Let’s hope it never happens - but if it does, knowing what to do could make the difference between surviving and not surviving. The sensible thing is to read these pages - or whichever parts are relevant to you or your child - before you encounter an emergency. It is often helpful to rehearse the procedure in your mind and actually imagine yourself going through the actions described here.
Find out in advance what the local ambulance service is like, and ask your GP for advice about who to contact in an emergency. (If you have latex allergy, check in advance that all local ambulances carry a latex-free kit.) These are the options:
• Call your GP.If the doctor is nearby and the hospital or ambulance station a long way off, this may be the best decision. Doctors in rural areas may have supplies of adrenaline for emergency treatment, and oxygen for those suffering a severe asthma attack.
• Call an ambulance. Where the local ambulance service is dependable, this is always the best option. The ambulance crew will have adrenaline and oxygen.
• Go by car or taxi to the nearest hospital
emergency department. This is not usually a
good plan, because your condition may quick-
ly get worse, and you have no emergency
treatment available. But there may be situa-
tions where it is a sensible decision. Emergencies can occur when you are away on holiday or business. Never stay anywhere without a phone – check that it is working as soon as you arrive. Make sure you have the number of a local doctor and know where the nearest hospital is. A remote holiday cottage can be a dangerous place to suffer an asthma attack or anaphylactic shock.
Anaphylactic shock
This is an extremely serious emergency, requiring immediate medical help. The signs of anaphylactic shock are listed on p.58. In the case of food allergy, there are additional signs in the mouth, lips and throat (see p. 62). Use adrenaline (epinephrine) straight away if you have it – but get emergency medical help as well. With injectable adrenaline (an EpiPen or Anapen – see p. 150), remove the cap and jab firmly into the outer thigh, going straight through any clothing. Never inject into any other part of the body – this can be dangerous.
If you have an adrenaline inhaler (see pp. 155-6) you can use this first to treat symptoms in the mouth, throat and airways, and then use the injector if you still have symptoms. (Improvise a spacer – see p. 100 – if there is difficulty in inhaling the adrenaline.) Anyone whose reactions tend to be severe should use the injector first and follow up with the inhaler if necessary. Overdosing with adrenaline is possible, and can be fatal, but using the inhaler as well as the injector is safe as long as you don’t have a heart condition (see pp. 155-6).
If you do not improve after using the injector, a second one can be used, 10-15 minutes later.
In situations where medical help is not yet available and the symptoms are not abating, another shot of adrenaline can be given every 15-20 minutes. But the maximum number of shots recommended by your doctor should never be exceeded. Keep count of how many you’ve had, and tell medical staff.
An asthmatic who does not have an adrenaline inhaler can use a beta-2 reliever inhaler such as Ventolin (see p. 152) as well as the adrenaline injection, although it probably won’t help very much.
Suppose you know for sure that you have encountered your allergen, but you don’t have any symptoms yet? In Britain, the usual advice is to wait for symptoms, but doctors in the United States say go ahead and use the adrenaline injector if you have reacted very badly in the past. In general, for people with no other health problems, it is better to give an adrenaline injection which isn’t needed than to delay giving one that is needed. Delaying the use of the injector may mean that the reaction gets out of control. Some people put off using the injector because they think it should be saved for when they ‘really need it’. In fact the adrenaline works just as well if you have used it on previous occasions.
Following anaphylactic shock, you should be kept in hospital for 6-12 hours even when everything seems fine. Attacks have recurred as much as eight hours later. Corticosteroids reduce the chance of this happening – ask if these have been given. If you are discharged early and it is a long journey home, consider waiting in the hospital, or nearby, until eight hours after the original reaction.
First aid for anaphylactic shock
A badly swollen tongue or throat can cause suffocation. If there is visible swelling and the person is unconscious or turning blue, try to keep the top of the trachea (the main airway leading from the throat) open. Use the handle of a spoon – one that has very smooth edges. Slide it carefully over the top of the tongue and into the throat. Press down gently but firmly to open the airway.
Someone who is feeling faint or dizzy, or losing consciousness, or (in the case of a child) becoming very pale and floppy, may be suffering from a dangerous drop in blood pressure. He or she is more at risk of a fatal collapse if in an upright position, because not enough blood is reaching the heart. The worst thing is to stand up suddenly, or to move (or be moved) quickly from a lying to a sitting position –death can follow within seconds. The best thing is to lie down, preferably with the legs resting on cushions or a stool so that they are above the torso, and with the arms raised above the chest. Adrenaline can be given while in this position. A stretcher should be used to get the patient to an ambulance.
Latex allergy and emergency treatment
If you have anaphylaxis due to latex allergy, going to hospital can be alarming, as you may suffer further reactions to latex gloves or equipment. Some patients with latex allergy have had such bad experiences in ambulances and hospitals that they become fearful of using their adrenaline injector, since this means they must go to the hospital afterwards. They delay using the injector, which makes the situation worse. Some doctors are now giving such patients all the medicines and training they need to manage their anaphylactic shock themselves, so that they don’t need to attend hospital.
A person who has lost consciousness should be lying down on their side in case they are sick (this reduces the chance of them inhaling their vomit). The same goes for anyone who feels nauseous.
On the other hand, if the major problem at the outset is difficulty in breathing (as it generally is in children) a sitting position is better.
It is unusual for both faintness and severe breathing problems to be present at once. If this occurs, the patient should lie down, and if there is swelling in the throat, a spoon should be used (see left) to keep the airways open.
Insect-sting allergy
If you don’t have an adrenaline injector, get medical help immediately.
If you’ve had a cutaneous systemic reaction (see p. 60) in the past, use the adrenaline injector if there is any difficulty in breathing, hoarseness, stomach cramps, diarrhoea, nausea, faintness, dizziness or confusion. If you are unsure, remember that, unless you have a heart condition, it is usually better to overreact (i.e. use the adrenaline unnecessarily) than under-react.
If you’ve had a severe systemic reaction (i.e. anaphylactic shock) in the past, use an adrenaline injector at the first sign of any reaction other than immediately around the sting.
If there is a honeybee stinger left in the skin, scrape or flick it out sideways using a fingernail, knife blade or credit card – the venom sac is attached and will go on injecting venom for up to 10 minutes if you leave it there.
Don’t try to pull the stinger out – this squeezes the venom sac and pumps more venom into the skin.
Get emergency medical help, and follow the other measures for dealing with anaphylactic shock (see left).
Don’t go alone
If you suffer vomiting or diarrhoea during anaphylaxis, and have to go to the toilet, tell someone to call an ambulance and take someone else with youto the toilet. Do not go in alone and lock the door, in case you collapse.
Asthma attacks
Even those with mild asthma, who have never had a serious attack before, can quite suddenly get into difficulties and require emergency treatment. Don’t be over-anxious about this, because it is unlikely to happen – but do be prepared. Not having your reliever inhaler with you when a severe attack starts is a recipe for disaster – always take it, wherever you go.
Deal with an attack promptly. The sooner you act, the fewer drugs you’ll need in the long run to control the attack. Most asthmatics wait too long and then under-treat their asthma.
The important thing is recognising an asthma attack, and knowing when it is getting out of control. Not all attacks are the same – some come on fast, some come on slowly.
Rapid asthma attacks come on in a matter of hours. You may have been fine all day, but then start to feel very breathless and wheezy, or begin coughing badly. Less than an hour later, despite using the reliever, the breathlessness is worse and it is a struggle to speak or walk across the room. This is a severe attack: don’t delay in getting medical help.
Slow asthma attacks come on over a period of days. At first you are more breathless and wheezy than usual, and your reliever inhaler is not helping much. Asthma wakes you up at night, and you are far more breathless than usual in the morning. This could be the beginning of a severe attack, so don’t delay in getting medical help. If you get to the point where your asthma is disturbing your sleep every night, and in the morning you have difficulty in speaking or walking about, this is a very serious situation – you must see your doctor or go to the hospital now.
A few asthmatics have great difficulty recognising when they are increasingly breathless, and for them, using a peak-flow meter (see p. 97) every day is essential. Indeed, most asthmatics find
Recognising an asthma attack in a very young child
With a young child, these signs indicate a severe asthma attack:
• the nostrils are flared
• the shoulders are unusually high
• the child can say only one or two words between breaths
• the ribs are pushed out, and the spaces between the ribs, and below the chest cage, are sucked in during breathing
• you can hear wheezing (a whistling noise)
• the lips, tongue or fingernails are blue.
If wheezing stops, without any other apparent improvement, this is a very bad sign — it may mean that the airways are now so narrow that no air is passing through them. This is called a ’silent chest’, and indicates an urgent need for medical attention.
that monitoring peak flow is a valuable way of spotting attacks in advance. However, if your peak flow seems normal, and yet you feel breathless and have a tight feeling in your chest, pay attention to your symptoms and get medical help.
Your response to your reliever inhaler is another helpful sign assessing asthma attacks. Things are serious if:
• the reliever inhaler does not seem to be working at all within 10 minutes of taking a puff
• it does not work as well as usual
• it works, but the effect wears off in less than three hours. If you have an asthmatic child, give everyone who normally takes care of the child detailed written instructions for recognising and dealing with an asthma attack. People forget verbal instructions especially in an emergency. A child who is exhausted or upset c. an attack should always be given medical care.
Taking action
If your reliever inhaler is not working well (see above), take another puff to open up your airways – and then take further action. as described below.
If you seem to be in the early stages of a slow asthma attack check your management plan, and if your peak flow has fallen below the recommended level, double the dose of inhaled steroids (twice as many puffs each time) now. Add any other medicines (e.g. steroid tablets) as recommended by the management plan.
Those who don’t have a peak-flow meter or management plan should double the dose of inhaled steroids and make an urgent appointment to see the doctor.
If you are suffering a rapid attack, or a slow attack that has got out of control, you need emergency medical help. Ring for an ambulance, ring your doctor, or go to the hospital – the ideal course of action will vary, depending on where you live (see p. 98).
Use your reliever inhaler until medical help arrives. You can take a puff every 5-10 minutes if needed, but keep a count of how many puffs you’ve had and stop after 30. Some doctors suggest taking up to 30 puffs all at once. (If you have a heart condition, this dose might be dangerous: follow your doctor’s advice.)
If it is difficult to inhale, use a spacer – this can make all the difference, especially for children.
You can improvise a spacer from a plastic cup, a plastic bottle, or a paper bag. Make a hole in the bottom of the cup or bottle, or in one corner of the paper bag, and insert the mouthpiece of the inhaler here. The open end of the cup, bottle or bag goes in or over the mouth – with the bag, you have to bunch it up and hold it around the mouth. Squirt the inhaler repeatedly into the improvised spacer, while breathing steadily in and out.
The six golden rules for asthma attacks
• Breathe as slowly as possible and concentrate on breathing out, not on breathing in. Exhale as fully as you can and your in-breath will follow automatically.
• Never panic – if you do, you may start hyperventilating, and this makes matters much worse (see p. 226). Panicky parents are the worst possible thing for an asthmatic child during an attack.
• Adopt a position that makes breathing as easy as possible. Propping your arms up at about shoulder height can help – for example, sit back-to-front on a dining chair, with your arms folded and resting on the back. Or put pillows on a table, sit in an upright chair, and rest your head and arms on the pillows. Don’t lie down, as this makes matters worse. Open a window, as long as the air outside is not cold, polluted or loaded with pollen.
• Avoid factors that can make an asthma attack worse, for example, vigorous activity, cold air, irritants and allergens.
• Drink plenty of water, fruit juice or other liquids as a lot of water is lost through the surface of the airways during an asthma attack, and you can become dehydrated.
• Don’t take anything to help you sleep, even herbal pills. If your asthma gets worse during the night, you need to wake up so that you can get more air.
After an attack
Asthmatics who have suffered a severe attack are occasionally sent home from hospital before they are completely better. A few people have died as a result of being discharged too soon. So if you feel breathless or otherwise unwell after you leave hospital, don’t hesitate to go back – or seek other medical help.
See your GP or specialist within a few days of any emergency treatment. Don’t be over-confident just after a severe attack – this can be a very vulnerable time. Take more rest than usual and drink plenty of fluids, as you may be dehydrated. Keep taking your preventer inhaler at the increased dose – reducing the dose now could lead to another severe, possibly fatal, attack. Keep taking steroid tablets if you have been given them.
If you produced a lot of mucus during the attack, try to clear it, but without violent coughing. Mucus can sometimes form solid plugs which block small airways. Treatment by a physiotherapist would help, and expectorants – drugs which help loosen mucus –can also be useful (ask your pharmacist about these). Don’t take ordinary cough medicine (see box on p. 163). There are also some breathing exercises which can help to clear mucus (see p. 231).
An asthma attack represents a chance to learn more about preventing asthma – so think about what went wrong. Had you forgotten to take your preventer inhaler regularly? How long is it since you had your medicines reviewed by the doctor or asthma clinic? Have you been using your peak-flow meter daily? Were you exposed to a high dose of allergen or an irritant?
A reaction to aspirin-like drugs
Aspirin sensitivity can begin quite suddenly in someone who has previously taken aspirin without trouble. If you have unexplained chronic urticaria, or polyps in the nose, plus asthma and/or rhinitis, the development of aspirin sensitivity at some time in the future is a distinct possibility (see p. 151).
A sensitivity reaction to aspirin or aspirin-like drugs usually begins between 30 minutes and two hours after the drug is taken. You will have some or all of these symptoms:
• a runny or badly blocked nose, and red eyes
• a feeling of warmth, flushing and sweating
• a general rash
• a sensation of tightness in the chest, a dry cough, increasing breathlessness
• malaise and exhaustion
• vomiting or diarrhoea
• swelling (angioedema) and/or nettle rash (urticaria). If you have such symptoms get emergency medical help immediately because the reaction can quickly develop into severe asthma, shock, collapse and unconsciousness.
If you have asthma, use your reliever inhaler as much as required (up to 30 puffs) until medical help arrives. Anyone who has an adrenaline (epinephrine) auto-injector, or an adrenaline inhaler, can use this as well – up to 30 puffs of the inhaler, or whatever maximum dose is given in the instructions. Tell the ambulance crew and doctors exactly what you have taken.
