the boy was kept in the ICU under intensive paediatric care till he died there on October 26, his ninth birthday

Friday, November 7th, 2008

New Delhi, November 6: In ’05, 8-yr-old died of internal burns and infection after a ‘rare’ fire in a laser machine, treating a tumour in his larynx, burnt his airway; HC finds hospital negligent

The death of an eight-year-old boy due to an “accidental” laser spark during a surgery at the Indraprastha Apollo Hospital has left the company that runs the country’s leading healthcare centre facing criminal action. Charges made out against the Indraprastha Medical Corporation Limited are “culpable homicide not amounting to murder” and “causing death by negligence”.

Aditya Pal died of internal burns and infection in October 2005, 23 days after a “rare” fire in a laser machine that was used to treat a recurrent tumour in his larynx (voice box) burnt his entire airway. After the surgery on October 3, the boy was kept in the ICU under intensive paediatric care till he died there on October 26, his ninth birthday, said his maternal grandfather Tej Singh, who is fighting the case against the hospital.

It was Aditya’s fifth visit to the hospital where he had been undergoing treatment since November 2004 for ‘recurrent laryngeal papillomatosis’.

The postmortem conducted the very next day by a specialist board of doctors from the All India Institute of Medical Sciences (AIIMS) had found it a “case of gross criminal negligence, and the burn injuries that were the primary cause of death were unwarranted and speak of failure of taking required precautions, care and skill in adopted procedure”.

In a recent order, the Delhi High Court agreed with the postmortem report and refused to quash a metropolitan magistrate’s direction issued in March 2007 to the Sarita Vihar police to investigate the hospital authorities and the doctors concerned under Sections 304 Part II and 304 A of the Indian Penal Code.

The boy’s family named the company running the hospital, its managing director, medical superintendent Ritu Rawat and the ENT consultant who had conducted the laser surgery on October 3, as accused in the complaint.

Rawat and the ENT consultant had moved the HC, seeking to quash the criminal proceedings.

The punishment under Section 304 Part II is imprisonment up to 10 years, but under Section 304 A it is a maximum of two years in jail.

“Aditya’s father had died of kidney failure in February 2005, but my daughter continued to stay with her in-laws in Meerut. Whenever it was time for Aditya’s treatment, I would pick them up from Meerut and later drop them back,” recalls Tej Singh, a resident of Loni.

The hospital authorities defended in the court that the postmortem report was “preliminary” in nature, and brought the judge’s attention to the November 2005 findings of an AIIMS medical board that had inspected the same laser machine and found it “working normally”.

Appearing for the hospital, senior advocate Siddharth Luthra argued that the Delhi Medical Council, on inquiry in 2006, had already given his client a clean chit and absolved the hospital of any negligence.

The council’s inquiry report termed the laser spark that claimed the boy’s life as “rare, and known to occur with the incidence of 0.5 to 1.5 per cent in the USA”.

Dismissing Luthra’s pleas, the Bench threw its weight behind the postmortem report.

It said the board that conducted the postmortem “had the body of the deceased who is alleged to have died on account of medical negligence with them while the other boards did not have the advantage of examining the body”.

Besides, the court observed that the inspection of the laser machine was done “considerably after the incident”, rendering the exercise far less conclusive.

The Apollo management, meanwhile, said it regretted the unfortunate incident, calling it “rare but not a case of medical negligence”.

“We have extended full cooperation to the investigating agency and will continue to do so,” their statement read.

SURVIVE A HEART ATTACK WHEN ALONE…

Monday, November 3rd, 2008

HOW TO SURVIVE A HEART ATTACK WHEN ALONE…

I dont know if you people have seen it somewhere already…I got it from another community and thought it was worth knowing…

Let’s say it’s 6.15p m and you’re going home (alone of course), after an unusually hard day on the job. You’re really tired, upset and frustrated.

Suddenly you start experiencing severe pain in your chest that starts to adiate out into your arm and up into your jaw. You are only about five miles from the hospital nearest your home. Unfortunately you don’t know if you’ll be able to make it that far. You have been trained in CPR, but the guy that taught the course did not tell you how to perform it on yourself.

Since many people are alone when they suffer a heart attack, without help,the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.

However,these victims can help themselves by coughing repeatedly and very vigorously. A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest.

A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again. Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating. The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart
attack victims can get to a hospital. Tell as many other people as possible about this. It could save their lives!!!

healthy dinner

Wednesday, September 3rd, 2008

Cooking doesn’t have to be about slaving for hours in the kitchen. Dietician Nigel Denby’s recipes show how easy it is to create quick healthy meals.

We are Europe’s biggest consumers of ready meals. And no wonder: we’re all leading increasingly hectic lives and it can be hard to muster the energy after a long day at work to prepare a healthy, balanced evening meal.

But there are ways you can whip up tasty nutritious dinners without slaving over a hot stove for hours or constantly resorting to ready meals. Try my seven-day plan and find out how easy, and enjoyable, cooking can be.

In part two, you’ll find my guide to making the healthiest choices when you do buy ready meals.

Before you start

On the side
If you’re serving the main course with a side, use these quantities and cooking times as a guide:
  • 50g couscous per person - 5 minutes
  • 75g basmati rice per person - 10-15 minutes
  • 75g brown rice per person - 25 minutes
  • 85g vegetables is one portion of your five a day. Steam 3-10 minutes, boil 5-15 minutes.
    • Planning is key - make a list of what meals you are going to eat during the week and go shopping with a list so you know exactly what you need.

    • Choose seasonal ingredients - they are likely to be fresher, in abundance, cheaper and higher in nutrients than imported out-of-season foods.

    • If you have some spare time at the weekend, have a cooking session and fill the freezer with ready portioned healthy meals that you can defrost and heat in a matter of minutes.

    • You could also make a habit of always cooking a double batch of whatever meal you are making and freeze half - this can work out cheaper, too.

    All these recipes serve two people, but can easily be increased to serve more.

    Monday

      • 2 salmon fillets

      • 100g couscous

      • handful sun-dried tomatoes, sliced

      • bunch spring onions, sliced

      • handful fresh dill

      • 1 garlic clove crushed

      • seasonal vegetables to serve

      • Prepare the couscous according to the instructions on the packet. Flavour with a squeeze of lemon juice and garlic.

      • Heap the couscous into the centre of two large sheets of greaseproof paper. Top with a handful of sun-dried tomatoes, spring onions and a salmon fillet.

      • Squeeze more lemon juice over the salmon and sprinkle with dill.

      • Wrap up the salmon to form a parcel.

      • Place on a baking tray and bake in the centre of the oven for 20 to 25 minutes.

      • Serve salmon in the paper bag with seasonal vegetables (steamed is best).

    Toddlers - making your home safe

    Tuesday, September 2nd, 2008

    Reviewed by Dr Stuart Crisp, paediatric specialist registrar

    Many toddlers are seriously injured in accidents around the home. These can include: falling down stairs, banging their heads, pulling objects on top of themselves, getting seriously scalded or burnt, or even falling out of windows that have not been properly shut or locked.

    Making your home as safe as possible will allow your child a better opportunity to explore their world in safety and give you peace of mind. However, it cannot be emphasised strongly enough that no matter how safe your home appears to be, parents should always keep an eye on their children. It is important to know where they are and what they are doing at all times.

    The kitchen

    The kitchen can seem like an exciting place for a child, but it is full of dangers: electrical appliances with trailing cords, kettles full of boiling water, hotplates or gas burners on the stove, hot saucepans and kitchen drawers full of sharp knives.

    The drawers and cupboards themselves can also be dangerous. If a drawer can be pulled out completely it could land on top of a child. It is also very easy for children to get their fingers trapped in drawers or doors. Because they don’t have complete control over their actions, they can easily slam a drawer shut on their hands.

    There are two ways to secure drawers and cupboards. You can fix a stopper to the drawers to prevent them being pulled out completely or fix a safety catch to prevent a child from opening the drawer or cupboard at all.

    It is also a good idea to fix a catch on the fridge door so that a child can’t get their fingers trapped, or even worse, climb inside. If the door closed by accident they would quickly suffocate or suffer from hypothermia.

    Cleaning products and household chemicals

    It is especially important to lock all cabinets that contain harmful or toxic products. Dish-washing agents, cleansing agents, detergent, petroleum, turpentine, flammable liquids and fertilizers are all toxic if swallowed. Dish-washing powder is also dangerous if it comes into contact with skin - for example, if a child spills a packet over themselves.

    Electrical cords

    It is very easy for a child to grab hold of an electrical cord and pull a kettle, blender, or other appliance onto themselves causing severe scalding or serious injury.

    This can be prevented by installing a cord holder, which will make the cord too short to reach over the edge of the table or work surface. You can also simply make electrical cords shorter.

    Stoves and ovens

    To prevent a child burning their fingers on hotplates or grabbing a saucepan handle and pulling the contents over him or herself, you can fix a grating at the edge of the stove. Always make sure that saucepan handles are turned inwards so children can’t reach them.

    You can also safeguard the knobs on the stove to prevent the child from turning on the stove or changing the temperature.

    Put a catch on the oven door so a child can’t open it. The glass window on the oven door may also get hot enough for your child to burn him or herself. You can prevent this by putting a fireguard or grate over the door.

    Living rooms and bedrooms

    Drawers and cupboards in the living room and bedroom can be secured in the same way as kitchen cupboards.

    There are many sharp, pointed edges in the living room - on tables and shelves for example - that a toddler could accidentally fall against. Low corners that could poke a child in the eye are especially dangerous. The best way to make them safe is to put plastic corners on them, or if you can’t find these, foam rubber secured with a rubber band. This may not look very attractive, but could save your child from serious injury.

    Use a wedge or hook on doors to hold them permanently open so that a child can’t get their fingers trapped.

    Windows

    As soon as toddlers are able to get around and explore their surroundings, they may start trying to climb up and look out of windows. If windows are not locked, put stoppers on them so they can’t be opened by more than 10cm. The best place to put them is at the top of the window so your child can’t reach them.

    Move furniture away from windows, so children can’t climb up in the first place.

    Shelving

    Some children may try to use book shelves as a climbing frame. Make sure all shelves are fixed securely to the wall so they can’t topple onto a child.

    Floor coverings

    Loose carpets and rugs are dangerous for children who are just learning to walk because they could easily trip over them. Put rubber matting or stoppers under the carpets and don’t put down loose rugs until the child is older.

    Tablecloths

    Toddlers will naturally grab hold of a dangling tablecloth to help themselves stand up. If you are using a tablecloth, make sure you fasten it to the table with pegs or clips so a child can’t pull the cloth and everything on the table over him or herself.

    Power points

    Electrical accidents are always very serious. They can cause severe third degree burns or even death.

    All power sockets should be secured with a plastic covering that a child can’t remove.

    Find out if there is a safety relay or circuit breaker in the house and if there isn’t, have one installed.

    The bathroom

    Children love playing with running water but it only takes 10cm (4in) of water for a small child to drown. If a small child’s face goes underwater, they will automatically breathe in so that they can scream and this will fill their lungs with water. Children also lose their sense of direction underwater, so they can’t react by pulling their head out or standing up as an adult would do.

    Put bath and basin plugs out of reach so that a child can’t fill up the bath or basin.

    The toilet lid can be held down with a clip attachment so a child can’t open it.

    You may want to adjust the thermostat on the boiler while your child is still a toddler so that if they turn on a tap, they won’t be scalded with very hot water.

    All medicine, tablets, vitamins and herbal remedies should be locked in a medicine cabinet or other cupboard so a child can’t get to them and swallow them - colourful pills are very attractive to children. Remember that medical poisonings can be extremely serious.

    Stairs

    Stairs are dangerous for children until the age of about four years. You can safeguard against falls by putting gates in front of the staircase.

    If there are openings between the steps, these should be blocked up to prevent your child from falling out underneath or getting their head stuck. A child’s head can also get lodged between the banister rails if they are more than 7.5cm (3in) apart.

    Babies - how to make your home safe

    Babies - how to make your home safe

    Reviewed by Dr Stuart Crisp, paediatric specialist registrar
    What you need to do to make your baby safe?

    Children have many accidents in the home that could be prevented by making the house and garden safer. It is also essential to choose baby equipment and toys that will not do your child any harm.

    Making your home safe also means being aware at all times of where your child is and what they are doing. And, should an emergency arise, knowing how best to react.

    A bed is not just a bed

    It is important that your baby has a good bed as they spend a lot of time there. A cradle can be cosy and romantic but may not be strong and safe enough after a couple of weeks. When your baby is able to turn over, it is time to replace the cradle with a cot.

    You should choose a quality cot with bars between 4.5 and 6cm apart to avoid the baby getting its head stuck. The height of the sides should be at least 60cm so your baby cannot climb over the edge. Make sure there are no mobiles low enough to get caught in.

    If you wish to protect the mattress, use a rubber sheet covered in cotton - not plastic which can cause suffocation. Make sure to fasten it securely under the mattress.

    Your baby’s blanket has to be light and of the right size. Do not use a pillow as it can cause suffocation and is bad for the baby’s back (babies should sleep on their backs as it helps to prevent cot death). Water beds are not safe for small children for the same reason.

    How to use a nappy changing table safely

    The table where the baby’s nappy is changed has to be stable with a high-sided cushion to avoid the baby rolling off.

    However, do not let this tempt you to walk away leaving your baby on the table. Even a newborn is strong enough to suddenly fall over the edge.

    Are you buying a safe dummy?

    The dummy must be undamaged and completely fastened to the shield. To try it out, hold it in one hand and the shield in the other and pull hard. There should be no loose parts.

    The shield has to be at least 4cm across to prevent the baby swallowing it. To be sure the dummy will not reach too far down the baby’s throat, don’t buy one longer than 3cm.

    How to choose safe toys for a baby

    Small toys are dangerous. Babies puts everything in their mouths to check them out. If they swallow something, it can choke them.

    Make sure teddy bears and dolls have no easily removable parts the baby could swallow.

    When your baby gets presents, you should see if they are tagged. Toys that are not safe for children under three years of age must, according to the law, be tagged.

    Buttons, coins, stones and other small objects are similarly dangerous to small children.

    Some musical boxes and toys can give out such loud noises that they are a hazard to a baby’s hearing.

    What is a safe playpen?

    Playpens should be strong, stable and durable enough not to collapse when the baby moves around vigorously. Care should be taken that there is nothing the baby can get caught in on the inside or outside of the playpen.

    If the playpen is upholstered, the material should be strong enough to avoid the baby biting or scratching through it and accidentally swallowing some of the stuffing.

    It is important that you measure the height and space between the bars of the playpen. The height has to be at least 60cm so the baby cannot crawl out and the space between the bars should not be more than 4.5 to 6cm.

    Is the bouncy-seat safe for baby?

    The bouncy-seat is a strain on your baby’s back and hips. Use it as little as possible. If you choose to use it, be aware that it can be dangerous to place on tables, or other high furniture, as the baby can fall off by rocking the chair.

    How to check that a pram or pushchair is safe

    The pushchair or pram has to be stable. It has to have effective brakes, strong joints and a safety mechanism to ensure that the ‘carriage’ pram will not suddenly collapse.

    If the folding top has a bright colour on the inside it may bother your baby’s eyes. During the summer, you should feel the temperature underneath the folding top with your hand before putting your baby in the pram. This is to make sure that the pram is not too hot. On sunny days, be sure to place the pram in the shade.

    Before putting your baby in the pram, make sure the top is fastened securely to the bottom.

    If you are using the pram for shopping, it is a good idea to put the groceries in the basket underneath to avoid destabilising it.

    Pushchairs should not be used for small children as their backs are not strong enough. Wait until the baby is able to sit up unaided.

    Carbon monoxide (CO) is an odourless, colourless, non-irritant gas. It is the most common cause of fatal poisoning in Britain today. It causes the accidental deaths of up to 50 people each year in the UK and a much larger number of sub-lethal poisonings.

    These figures could be just the tip of the iceberg as poisoning by carbon monoxide is almost certainly underdetected. There are two main reasons for this.

    Firstly, there is generally little awareness of carbon monoxide poisoning among the general public and the medical profession.

    Secondly, the signs and symptoms associated with carbon monoxide poisoning are not easy to diagnose as they often mimic many other conditions.

    To overcome this deadly killer requires improved awareness among the public of the risks and dangers of carbon monoxide poisoning and increased vigilance on the part of healthcare professionals in its detection.

    Children, pregnant women, babies, and individuals with a heart condition are those at most risk but CO poisoning can affect anyone.

    Where does carbon monoxide come from?

    Carbon monoxide is produced by the incomplete combustion of carbon-containing fuels, such as gas (domestic or bottled), coal, oil, coke and wood. Gas stoves, fires, heating boilers, gas-powered water heaters, paraffin heaters, and solid fuel-powered water heaters are all potential sources of carbon monoxide. The problem arises when such appliances are poorly maintained, not serviced and housed in poorly ventilated areas.

    When the waste products of combustion are not effectively removed, for example because of blocked flues and chimneys, then poisonous gas mixtures may re-enter the room. This problem is not just associated with older or poorer homes; it can also affect the occupants of newer homes with gas central heating. Exhaust fumes from cars is another obvious source.

    Domestic sources of carbon monoxide include:

    • domestic heating systems

    • blocked flues/chimneys

    • inadequate ventilation in living areas

    • inadequate ventilation in adjoining car garages

    • leakage from faulty appliances and chimneys/flues.

    How is carbon monoxide formed?

    When any fire burns, in an enclosed room, the amount of oxygen available gradually decreases. At the same time the amount of carbon dioxide increases. As the amounts of these two gases change, this increasingly causes the combustion process to alter from one of complete combustion to one of incomplete combustion. This results in the release of increasing amounts of CO.

    This highlights an important issue. Even with perfectly designed and maintained heating appliances (or any kind of combustion device), they too will eventually begin producing dangerous amounts of CO if used in confined and poorly ventilated areas. Having poorly operating appliances, only makes the problem worse more quickly. Maintaining appliances and ensuring sufficient fresh air is available are two easy ways of avoiding potentially lethal scenarios.

    How does carbon monoxide cause poisoning?

    To explain this aspect, we need to explain how the body uses oxygen from the air. Oxygen is transported around the body via the red blood cells. Specifically, oxygen binds to a substance within the red blood cells called haemoglobin, which is also responsible for their red colour.

    Haemoglobin takes up oxygen as blood passes through the lungs, and at the same time carbon dioxide, produced by the body’s metabolism, is released from the blood into the exhaled breath. The combination of oxygen with haemoglobin is called oxyhaemoglobin and this ‘oxygenated’ blood is carried away from the lungs through the bloodstream to all the tissues of the body.

    Carbon monoxide can also bind to haemoglobin but does so about 240 times more tightly than oxygen, forming a compound called carboxyhaemoglobin. This means that if both carbon monoxide and oxygen are inhaled, carbon monoxide will preferentially bind to haemoglobin. This reduces the amount of haemoglobin available to bind to oxygen, so the body and tissues become starved of oxygen.

    Carboxyhaemoglobin also has direct effects on the blood vessels of the body - causing them to become ‘leaky’. This is seen especially in the brain, causing the brain to swell, leading to unconsciousness and neurological damage.

    What are the symptoms of carbon monoxide poisoning?

    One of the difficulties with diagnosing carbon monoxide poisoning is that many of its symptoms are similar to those of other conditions. Often the onset of symptoms is gradual, occurring without the individual or doctor being fully aware of what is happening. Coupled with this is the fact that the severity of the poisoning depends on:

    • how much carbon monoxide is actually present in the environment.

    • the duration you are exposed to carbon monoxide.

    • the age of the individual concerned - elderly, children and the foetus are all at greater risk.

    • the general state of health.

    • the extent of physical activity - effects are increased with higher activity levels.

    The commonest symptoms (with frequency of occurrence in brackets) include:

    • headache (90 per cent)

    • nausea and vomiting (50 per cent)

    • vertigo (50 per cent)

    • altering states of consciousness (30 per cent)

    • weakness (20 per cent).

    The likely symptoms in adults, children and infants are shown in Table 1.

    Table 1: Likely symptoms of CO poisoning
    Symptoms Adult Child Infant
    General Dizziness, fatigue, weakness . Not feeling well
    Neurological Headache, drowsiness, disorientation, fits Headache, drowsiness, fits, uncoordinated movement .
    Stomach/intestine Nausea, vomiting, stomach pains Vomiting, stomach pains, anorexia, diarrhoea Loss of appetite
    Heart Chest pain, wheeziness, palpitations, hyperventilation Hyperventilation .

    How is carbon monoxide poisoning diagnosed?

    Individuals can either be exposed to high levels of carbon monoxide over a relatively short period of time (acute exposure) or to lower levels of exposure over a longer period of time (chronic exposure).

    Acute exposure is easier to diagnose as the symptoms are more pronounced, but it is the more common chronic exposure symptoms that are more subtle and difficult to tell apart from other conditions. Where whole families are affected by suspected ‘food poisoning’ this has been known to be due to carbon monoxide exposure.

    Where such symptoms are reported repeatedly, domestic carbon monoxide poisoning should be suspected. Clues that point towards a problem within the home include:

    • more than one family member being affected

    • symptoms appear or get worse when gas appliances are in use

    • symptoms are worse in the winter when gas boilers/heaters are in use

    • symptoms improve when family members are not at home, but recur on their return.

    Important information can also be obtained by inspecting gas-operated heating appliances within the home. Relevant points include:

    • black soot marks on gas fire burners or on walls near cookers, boilers, gas fires

    • a yellow gas flame colour, rather than the blue colour it should be.

    How is carbon monoxide poisoning treated?

    The first step is to move the affected individual(s) away from further exposure to the carbon monoxide source. Their signs and symptoms will then determine what happens next. If the individual is only mildly affected they should seek medical attention, but may not need to be admitted to hospital. All other exposed individuals will require hospital treatment.

    Administering 100 per cent oxygen, via a tightly fitting mask with an inflated face-seal, is the first treatment. A high concentration of oxygen in the air being breathed will speed up the formation of oxyhaemoglobin to replace carboxyhaemoglobin. The severity of the CO exposure can be checked by measuring the amount of carbon monoxide in the air breathed out by the individual or by taking a blood sample and measuring the carboxyhaemoglobin levels, and taking these laboratory tests along with the clinical signs and symptoms present in the affected person.

    If exposure is deemed to be significant and signs indicate nerve damage, then ‘hyperbaric’ oxygen therapy should be considered. This involves placing the individual in a sealed pressure chamber, similar to those used in treating decompression sickness in divers, and exposing the person to oxygen at high pressure. Using this technique there is greater penetration of oxygen at tissue level, and oxygen displaces carboxyhaemoglobin from the red cells more quickly.

    As a guide to who should be offered hyperbaric oxygen therapy the following indications have been recommended:

    • loss of consciousness

    • neurological signs (other than a headache)

    • abnormal heart rhythm or lack of blood to the heart

    • women who are pregnant.

    It should be noted that this treatment is still considered controversial. Although it speeds the reduction of carboxyhaemoglobin in the blood back to normal levels, symptom reduction may not be seen at the same time.

    Prevention is always better than cure

    The best course of action is to take steps that prevent carbon monoxide becoming a problem in the first place.

    • Raise the general awareness of the risks associated with carbon monoxide by communicating the relevant information to friends, family and work colleagues.

    • Be aware of the sources of carbon monoxide especially in domestic properties where a number of appliances could be responsible.

    • Get appliances professionally installed and regularly serviced to ensure they work efficiently and safely.

    • Ensure adequate ventilation for all fuel burning appliances.

    • Install monitoring devices for the early detection of excess carbon monoxide.

    • Recognise the early signs and symptoms of carbon monoxide poisoning, particularly when more than one family or work member is affected, and seek medical advice promptly.

    How do you measure carbon monoxide levels?

    Carbon monoxide levels can be measured either in the environment or in the blood. The latter is usually performed in a hospital setting to check how much carbon monoxide (in the form of carboxyhaemoglobin) there is present in the blood. There are also ways by which carbon monoxide levels can be monitored in the home or office.

      • Chem-optical (gel cell) technology

        Chem-optical technology (or gel cell or biomimetic technology) alarms use a type of sensor that simulates haemoglobin in the blood.

        Electrochemical alarm

        Electrochemical alarms work by converting the carbon monoxide electrochemically to carbon dioxide, which generates an electrical current that is taken as a measure of the gas concentration. Electrochemical alarms are usually powered by a battery lasting about five years.

        Semiconductor technology

        These alarms use semiconductors or tin dioxide technology to detect carbon monoxide levels. Unlike the alarms above, semiconductor detector alarms do not require any replacement sensors.

    • Carbon monoxide monitors

      Carbon monoxide detectors are available from most local hardware and DIY stores. They can provide an audible high-pitched alarm when high levels of carbon monoxide are detected or provide an alarm plus a digital display of the concentration of carbon monoxide detected in units of ‘parts per million’ (ppm).

      Three types of carbon monoxide detectors are available.

    The British Standards Institute (BSI) is a national standards body, responsible for ensuring products meet certain agreed standards of safety. BSI standard BS7860 is the one for monitors that detect carbon monoxide at levels well before they become dangerous for humans.

    What to do if the alarm sounds

    It is essential to read the instruction manual accompanying the detector as it provides important information on where to place it, how to use it and what to do if the alarm goes off. It will also contain important information about the levels of carbon monoxide detected and the risks associated with varying levels. The manual should be placed somewhere (ideally near the detector) so it can be accessed quickly in the event of an emergency. The following are some general points to bear in mind.

    • If your alarm goes off and you have a detector that displays the amount of carbon monoxide detected, make a mental note of what the reading states. Pick up the instruction manual but take it outside the house to read it.

    • Check whether you or any other family member is affected by any of the signs and symptoms of carbon monoxide poisoning (headache, dizziness, nausea, fatigue). If carbon monoxide poisoning symptoms are suspected, everyone should vacate the house and call for medical assistance. Dial 999 for an ambulance if necessary.

    • If no one has any symptoms of poisoning, promptly turn off all gas or other fuel burning appliances. Ventilate the whole house by opening all windows and doors.

    • Contact a professional appliance specialist, eg British Gas or other CORGI (Council of Registered Gas Installers) registered gas specialists, to check your appliances.

    heart attack

    Tuesday, September 2nd, 2008

    Reviewed by Dr Neal Uren, consultant cardiologist and Dr Reginald Odbert, GP

    important: this is a brief guide to the emergency help that can be given in the event of a heart attack or cardiac arrest before the arrival of emergency services. It is not intended as a replacement for a first aid or resuscitation course.

    What Your Soul Sings



    What should you do if someone has a heart attack?

    If someone has a cardiac arrest or heart attack, there are only a few minutes to act before it is too late. It is vital to know what to do beforehand.

    To perform CPR (cardiopulmonary resuscitation) and artificial respiration (mouth to mouth resuscitation) effectively, training and frequent practice on resuscitation dummies are essential.

    First aid courses are offered all over the country at night schools or by voluntary organisations such as St John Ambulance or The Red Cross.

    How can you tell if someone is having a heart attack?

    If the person is unconscious:

    • are they breathing? Look at the patient’s chest to see if it is rising and falling.

    • do they have a pulse? Place two fingers on one or other side of the person’s voice box in their throat to feel if they have a carotid pulse.

    If the patient has a pulse but is not breathing:

    • could it be because of suffocation? Feel inside the mouth with a finger to see if there is anything blocking it or the windpipe and remove any food or other objects. Provided that dentures are not broken, it is better not to remove them.

    • call for help immediately, stating that the casualty is not breathing, and provide resuscitation (see below) until the patient begins to breathe or the ambulance arrives.

    If there is no breathing or pulse, the patient has had a cardiac arrest.

    What help is needed?

    • If possible, raise the legs up 12 to 18 inches to allow more blood to flow towards the heart

    • Immediately place the palm of your hand flat on the patient’s chest just over the lower part of the sternum (breast bone) and press your hand in a pumping motion once or twice by using the other hand. This may make the heart beat again.

    If these actions do not restore a pulse or if the subject doesn’t begin to breathe again:

    • call for help, stating that the casualty is having a cardiac arrest but stay with the patient.

    • find out if any one else present knows CPR.

    • provide artificial respiration immediately (see below).

    • begin CPR immediately (see below).

    How to give artificial respiration

    • Tilt the head back and lift up the chin.

    • Pinch the nostrils shut with two fingers to prevent leakage of air.

    • Take a deep breath and seal your own mouth over the person’s mouth.

    • Breathe slowly into the person’s mouth - it should take about two seconds to adequately inflate the chest.

    • Do this twice.

    • Check to see if the chest rises as you breathe into the patient.

    • If it does, enough air is being blown in.

    • If there is resistance, try to hold the head back further and lift the chin again.

    • Repeat this procedure until help arrives or the person starts breathing again.

    How do I perform CPR (cardiopulmonary resuscitation)?

    See if there is breathing. If not, start artificial respiration as described above. Checking for a pulse in the neck (carotid artery) may waste valuable time if the rescuer is inexperienced in this check. The procedure is:

    • place your fingers in the groove between the windpipe and the muscles of the side of the neck. Press backwards here to check for a pulse.

    If there is no pulse, or if you are unsure, then proceed without delay thus:

    • look at the person’s chest and find the ‘upside-down V’ shaped notch that is made by the lower edge of the ribcage. Place your middle finger in this notch and then place your index finger beside it, resting on the breastbone. Take the heel of your other hand and slide it down the breastbone until it is touching this index finger. The heel of your hand should now be positioned on the middle of the lower half of the breastbone.

    • now place the heel of your other hand on top of the first. Keep your fingers off the chest, by locking them together. Your pressure should be applied through the heels of the hands only.

    • keep your elbows straight, and bring your body weight over your hands to make it easier to press down.

    • press down firmly and quickly to achieve a downwards movement of 4 to 5cm, then relax and repeat the compression.

    • do this 15 times, then give artificial respiration twice, and continue this 15:2 procedure until help arrives.

    • aim for a rate of compression of about 100 per minute. You can help your timing and counting by saying out loud ‘one and two and three and four …’ etc.

    Artificial respiration and CPR should both be performed at the same time

    • If possible, get someone else to help - one person to perform artificial respiration and the other to perform CPR. (This is not easily done without prior practice and it is well worth attending sessions on CPR training to become familiar with the technique.)

    • The ratio of chest compressions to breaths is 15:2 for both one-person and two-person CPR.

    • Continue until the ambulance arrives or the patient gets a pulse and starts to breathe again.

    • If the pulse returns and breathing begins but the person remains unconscious, roll them gently onto their side into the recovery position. This way mucus or vomit can get out of the mouth and will not obstruct the patient’s breathing. It also prevents the tongue from falling back and blocking the air passage.

    Make sure the patient continues breathing and has a pulse until the ambulance arrives

    • If you succeed in resuscitating the person who has been taken ill, he or she may be confused and alarmed by all the commotion. Keep the patient warm and calm by quietly, but clearly, telling them what has happened.

    Again, it needs to be emphasised that the only way to provide proper first aid and resuscitation is through learning the technique, then regular practice and guidance.

    First-aid kit

    First-aid kit

    first aid

    Reviewed by Christine Clark, pharmacist  and Dr John Pillinger, GP

    First-aid kit basics

    A first-aid kit contains emergency supplies and medication for unexpected minor illnesses or accidents.

    While it is vital for people who suffer from a chronic disease or condition to take their medication with them at all times, it is also a good idea for everyone to keep a first-aid kit in the home or car, or take one with them on holiday in case of emergencies.

    If going abroad, talk to your doctor before leaving about arrangements for vaccinations or special medication such as malaria tablets.

    Although it is possible to buy additional items for your first aid kit when you are abroad, it is a good safeguard to purchase extra supplies and medication before your departure. Emergency situations occur unexpectedly and you may find yourself unable to obtain essential items just when you need them most.

    Remember that medicines suitable for adults are not always suitable for children as well. Always read the label to check who can take the medicines in your first-aid kit, and at what dose.

    Motion sickness

    Medication to prevent motion sickness caused by car, air or sea travel can be bought over the counter without prescription. If necessary, this should be taken before starting a journey.

    Diarrhoea, irregular bowel movements or indigestion

    It is a good idea to be prepared for diarrhoea. Medication to treat it is available both on prescription or over the counter at your local pharmacy.

    If diarrhoea or vomiting occur despite these precautions you will need to make sure the patient gets enough liquid. This is especially important where children are concerned.

    Cola drinks are particularly helpful since they replace essential salt and sugar as well as provide a source of liquid, but a first-aid kit should also contain a rehydration medicine (a powder or large tablet that is dissolved in clean water, for example Dioralyte) to prevent dehydration.

    Many people get constipation when travelling. A mild laxative, available from a pharmacy, usually relieves most symptoms.

    For people who suffer from indigestion or heartburn when eating spicy food, it is a good idea to keep a supply of antacid preparation in the first-aid kit.

    Pain relievers

    Aspirin (eg Aspro clear), paracetamol (eg Panadol) or ibuprofen (eg Nurofen) can be bought over the counter. They come in different forms including soluble tablets, ordinary tablets or suppositories, and can relieve headache, muscle pain, toothache and period pain. Aspirin should not be given to children under 16 years of age, unless on the advice of a doctor.

    Fever

    Fever is most commonly caused by viruses that cannot be treated with antibiotics. Even though antibiotics can be bought in some countries without a prescription, they should be avoided. If antibiotics are necessary, a GP should be consulted. A doctor will be able to prescribe the appropriate antibiotics or other medication.

    Sunburn

    A sunblock to be applied prior to exposure to the sun should always be included in a first-aid kit, along with cream and lotion for use after sunbathing. The pharmacist should be consulted as to the appropriate screening (SPF-sun protection factor) level.

    Insect bites

    Antihistamines and soothing lotions such as calamine are effective at controlling the itching of insect bites or stings.

    Cuts and grazes

    The following items are all useful for treating minor cuts and grazes:

    • sticking plasters

    • cotton wool

    • safety pins

    • a gauze bandage and supportive bandages

    • antiseptic lotion or saline to clean wounds.

    Do I need to take everything wherever I go?

    There is no need to take everything with you. Indeed, a longer trip might require more supplies than a shorter one. Buy products in small sizes that fit easily into your luggage. Remember that all drugs have a ‘use by’ date and should be thrown away after they have expired.

    Why learn first aid?

    WARNING!
    This advice is a general guideline for use in an emergency.
    It is not intended to replace professional classes in first aid and resuscitation.

    First aid is an important skill. By performing simple procedures and following certain guidelines, it may be possible to save lives by giving basic treatment until professional medical help arrives.

    Remember, too, that practice makes perfect. In an emergency there is no time to read instructions. If you’ve memorised some of the basic procedures, it will help you react quickly and efficiently.

    Breathing difficulties

    If someone stops breathing, see if the person replies if talked to or touched on the shoulder. If not, call an ambulance and then begin first aid.

    • Place the person on his or her back on the floor.

    • Tilt the head so that the chin is pointing upwards. Do this by placing the fingertips under the jawbone, then lift gently while pressing down softly on the person’s forehead. This is done to make sure the tongue is not blocking the throat.

    • Keep holding the head in this way while checking for breathing: see if the chest is rising and falling, or place your ear next to their mouth to listen for breathing.
