First Aid: IntroductionCHAPTER 1

 
DEFINITION
First aid is the immediate and temporary care given to the victim of an accident or sudden illness. Its purpose is to preserve life, assist recovery and prevent aggravation of the condition until the services of a doctor can be obtained or during transportation to hospital or to the casualty's home.
The term ‘first aid’ was adopted officially in England for the first time in 1879 by the St John Ambulance Association. The expression ‘first aid’ had not come till 1894 and intended to designate any person who has received a certificate from an authorized association that he/she is qualified to render first aid.
 
OUTLINE OF FIRST AID
The principles and practice of first aid are based on the principles of practical medicine and surgery, knowledge of which, in case of accident or sudden illness, enables trained persons to give such skilled assistance as will preserve life. Promote recovery and prevent the injury or illness becoming worse until medical aid has been obtained.
The term ‘medical aid’ is used to indicate treatment by a doctor either on the spot, in the home or in hospital. The first aider's responsibilities ends as soon as medical aid is available, but he/she should standby after making his/her report to the doctor in case he/she can be of further assistance.
First aid is definitely limited to the assistance rendered at the time of emergency with such material as may be available. It is not intended that the first aider should take the place of the doctor and it must be clearly understood that the redressing of injuries and other such after treatment are outside the scope of first aid.4
Throughout the manual standard methods of treatment are given for a number of defined conditions, which may occur in different circumstances, but the first aider will find that these conditions seldom conform to an exact pattern and that even in the same circumstances individuals may react in different ways. He/She must be prepared to sum up any situation with which he/she may be faced and adapt himself/herself to wide variation from the average or typical.
 
SCOPE OF FIRST AID
  1. To determine the nature of the case requiring attention so far is necessary for intelligent and efficient treatment—diagnosis.
  2. To decide on the character and extent of the ‘treatment’ to be given and to apply the treatment most suited to the circumstances until medical aid is available.
  3. To arrange for the ‘disposal’ of the casualty by removal either to his/her home or other suitable shelter, or to hospital.
 
DIAGNOSIS
In deciding nature of the case, first aider must consider its ‘history, symptoms and signs’.
 
History
History is the story of how an accident or sudden illness occurred. This may be obtained from the casualty (if conscious) or from witnesses. It may be information that a person is subject to a particular disease or the surroundings may suggest the cause, e.g. a broken bicycle.
 
Symptoms
Symptoms are the sensations of the casualty such as feeling cold or shivery, faintness, nausea, thirst pain, which can be obtained, if conscious casualty describes. Pain is a very helpful diagnostic point for the first aider as it draws his/her attention to the part, which is most probably in trouble and saves a great deal of time during his/her examination of the casualty.5
 
Signs
Signs are any variations from the normal conditions of the casualty such as pallor, congestion, swelling and deformity, which can be observed by the first aider. Signs are the most reliable indications on which to base diagnosis, but the circumstances of each particular case will determine the relative importance of history, symptoms and signs.
 
TREATMENT
If the cause of the condition is still active, remove the cause if possible (e.g. a log of wood on leg), or remove the casualty from the cause of the conditions (e.g. gas-filled room). Give treatment to preserve life, promote recovery and prevent the condition becoming worse. Pay special attention to the treatment of failure of breathing, severe bleeding and shock. When there is the slightest doubt as to whether a casualty is dead or alive, continue treatment until medical aid has been obtained.
 
DISPOSAL
The speed with which a casualty is brought under medical care is of tremendous importance in his/her recovery. Unless the casualty is examined by a doctor on the spot, it is the responsibility of the first aider to see that he/she is conveyed to his/her home (or other suitable temporary shelter) or to hospital as soon as possible in the manner most suitable in the circumstances. A tactful message should be sent to the casualty's home or relatives indicating in a general way, ‘what has happened and the casualty's destination’.
 
MANAGEMENT OF THE CASE
The first aider must always:
  1. Respond quickly to calls for assistance, the saving of a life may depend on promptness of action.
  2. Adopt a calm and methodical approach to the casualty, quick and confident examination, and treatment, which will relieve pain and distress, lessen the effect of the injury and may save life. Time spent on long and elaborate examination of a casualty may be time lost in his/her ultimate recovery.6
  3. Treat obvious injuries and conditions endangering life such as failure of breathing and severe shock, before making a complete diagnosis.
  4. Take first aid material, if this is immediately available. If standard equipment is not available, the first aider must depend on material to hand, which will have to be improvised as required.
  5. Study the surroundings carefully. These may influence the action to be taken and therefore require careful consideration, for example:
    1. Danger: From falling building, moving machinery, electric current, fire, poisonous gases and similar hazards.
    2. Weather: If the accident occurs out-of-doors, the casualty may be treated in the open air if the weather is fine; if the weather is bad, he/she must be removed to shelter as soon as is reasonably possible.
    3. Shelter: Houses and buildings near at hand, whether occupied or unoccupied, and whether likely to be particularly useful (e.g. a chemist's shop), otherwise, temporary shelter may be provided by means of umbrellas, rugs, etc.
    4. Light: It is impossible to treat a patient satisfactorily without sufficient light, and the first aider must provide for this.
    5. Assistance: Crowds must be tactfully controlled. If a doctor is present, work under his/her direction. If not, ask if anyone with knowledge of first aid is present. If neither is available make use of bystanders to the best advantage.
    6. Reassure the casualty: By speaking encouragingly, warn him/her to be still and tell that he/she is in trained hands.
 
GOLDEN RULES OF FIRST AID
  1. Do ‘first things first’ quickly and without fuss or panic.
  2. ‘Give artificial respiration’, if breathing has stopped—every second counts.
  3. Stop any bleeding.
  4. ‘Guard against or treat for shock’ by moving the casualty as little as possible and handling him/her gently.
  5. ‘Do not attempt too much’—do the minimum that is essential to save life and prevent the condition from worsening.
  6. ‘Reassure the casualty’ and those around; so help to lessen anxiety.
  7. Do not allow people to crowd around as fresh air is essential.7
  8. Do not remove clothes unnecessarily.
  9. Arrange for the removal of casualty to the care of a doctor or hospital as soon as possible.
 
ACTION AT AN EMERGENCY (CONCEPT OF EMERGENCY)
The basic principles of first aid apply to all injuries or illnesses regardless of severity. Whatever the incident, it is the first aider's responsibility to act quickly, calmly and correctly in order to:
  • Preserve life
  • Prevent deterioration in the casualty's condition
  • Promote recovery.
    These objectives are best achieved by:
  • A rapid, but calm approach
  • A quick assessment of the situation and the casualty
  • A correct diagnosis of the condition based on the history of the incident and the casualty's history, symptoms and signs
  • Immediate and appropriate treatment of any conditions diagnosed
  • Proper disposal of the casualty according to the injury or condition.
 
Approach
Approach should be speedy, but calm and controlled. Ensure that you are not placing yourself in any danger when approaching the casualty. On arrival at the scene of any incident, state that you are a trained first aider and, if there are no doctors, nurses or more experienced people present, calmly take charge.
 
General Rules
Whenever and wherever you come across an emergency, use common sense, know the limitations and do not attempt to do too much.
 
Assessing the Situation
As soon as you have taken control at an incident, it is crucial to make an accurate assessment of the situation and decide on the priorities of action. To do this you must consider:8
  • Whether you and the casualty are not in any danger
  • If the casualty has any life-threatening conditions
  • If any bystanders can help you
  • Whether you need to call for assistance.
 
Safety
You must minimize the risk of danger to yourself, the casualty and bystanders, and guard against any further casualties arising (for example, in the case of road accidents).
Road accidents
Instruct a bystander to control traffic, keeping it well away from yourself and the casualty. Watch out for life risks, especially from petrol spillage and switch off the ignition of the vehicles concerned (refer Chapter 5 for more details of ‘procedure at major incidents’).
 
DETERMINING PRIORITIES
  • In order to determine the condition of a casualty, ask him/her “What happened?”
  • A reply will help you to know what to look for
  • It also tells you that he/she is conscious; his/her airway is clear; he/she is able to breathe, if he/she does not respond to questioning or touch, perform the following checks immediately.
 
Airway, Breathing and Circulation
  1. Following the airway, breathing and circulation (ABC) rule quickly check that the airway is open and that the casualty is breathing. If not, commence artificial ventilation immediately (Figs 1.1A and B).
  2. Check pulse for circulation (Fig. 1.2). If absent, commence ‘external chest compression’. Check for any severe bleeding and control it.
 
Unconsciousness
Place an unconscious casualty or one whose breathing is noisy, in the recover position (refer Chapter 4, topic on ‘recovery position’) and assess the level of responsiveness (refer the topic ‘levels of responsiveness’).9

If there is any possibility of spinal injury, do not turn the casualty and keep in spinal recovery position (refer the topic ‘examining the spine’) unless difficulty in breathing makes it essential, or vomiting is likely to occur:
  • Gas and poisonous fumes: If possible cut off the source and ensure adequate ventilation
  • Electrical contact: Break the contact, if possible, and take the necessary precautions against further contact
  • Fire and collapsing buildings: Move the casualty to safety immediately, if you can do so without endangering your own life.
 
Getting Others to Help You
Some bystanders can be extremely useful and may be able to assist with treatment. For example:
  1. Controlling severe bleeding or supporting a badly injured limb.
  2. Other bystanders may become nuisances so you must keep them occupied to prevent their interfering with your work. They can be asked to control traffic crowds, or be sent to telephone assistance.

However, when sending bystanders to the telephone 10make sure that they understand the message that is to be sent. If possible, ask them to write it down, but in any case, ask them to repeat the message to you before actually sending it. Always make sure that they report back to you afterwards.
 
Shock
Keep the casualty warm, quiet and lying down until skilled help arrives.
 
Other Needs
Unless there is immediate danger to life from the surroundings, treat all fractures and large wounds before moving a casualty. If the casualty is in danger, support the injured part whilst moving (refer Chapter 9) or you suspect that the casualty has a fractured spine.
 
CALLING FOR ASSISTANCE
Once you decide that assistance is required, and this may include ambulance, police, fire brigade, gas or electricity boards, send for it immediately. Go to the nearest telephone booth for ambulance service required. Do not leave the casualty unattended. Whether you are giving the message yourself or instructing someone to do so make sure that the following information is passed on:
  1. Your telephone number.
  2. The exact location of the incident; if you can point out nearby road junctions for other landmarks.
  3. An indication of the type and seriousness of the incident, e.g. road traffic accident, two cars involved, three people trapped.
  4. The number, sex and approximate age of the casualties involved and if possible, the nature of their injuries.
  5. Request for special help and if you suspect a heart attack or childbirth.
 
Multiple Casualties and Injuries
Where there is more than one casualty, you must decide by rapid assessment, which one needs priority of treatment. Remember that the noisiest casualty is rarely the most severely injured. In first aid, common sense is almost as important as the actual knowledge of the subject.11
In real life, serious accidents rarely produce only a single injury, frequently two or more injuries occur so that the correct treatment of one may interfere with the correct treatment of the other. In such circumstances you must decide, which injury is the more serious one and treat that in the correct way. You should then deal with the other injuries correctly as possible under the conflicting circumstances.
 
Examination and Diagnosis
Examination and diagnosis means taking account of the casualty's history and that of the incident, the symptoms, signs and levels of responsiveness.
 
History
History is the full story of how the incident occurred or the illness began, and should be taken directly from the casualty and a responsible bystander wherever possible. Never hurry the casualty and remember to pass on all the information you have obtained when skilled help arrives.
 
Symptoms
Symptoms are sensations that the casualty feels and describes to you—the most useful of these is pain. If the casualty is unconscious or unreliable because dazed or in shock, their diagnosis cannot be based on symptoms, but has to be based on information obtained from bystanders and signs.
 
Signs
Signs are the details ascertained by you using your senses—sight, touch, hearing and smell. These may be signs of injury such as bleeding, swelling, deformity or signs of illness such as raised temperature and/or a rapid or one irregular pulse.
 
HOW TO CARRY OUT AN EXAMINATION?
A general examination should be carried out quickly to discern any imminent threats to life whether the casualty is conscious or unconscious when examining a casualty. There are certain rules to follow:12
  • Move him/her as little as possible to avoid aggravating any injuries
  • Begin examination at the head and work methodically towards his/her feet
  • Remember to use all your senses—look, feel, listen and smell
  • Always compare one side of the casualty's body with the other as this makes it easier to detect any swellings or irregularities that require first aid.
 
Examining the Head
 
Mouth
Recheck breathing, noting the rate, depth and nature (whether easy or difficult, noisy or quiet); note also any odor. Check inside of the mouth to ensure it contains no foreign matter, such as vomit, blood, food or loose teeth that might cause choking.
 
Lips
Examine the lips for any signs of burning or discoloration that might indicate corrosive poisoning. Look inside the lips for blueness, which might indicate asphyxia.
 
Teeth
Check the teeth to make sure that any recently dislodged teeth have not fallen down into the back of the throat. Make sure that dentures are firm fitting (essential for resuscitation); if they are not, remove them.
 
Eyes
Examine both together comparing the pupils (the black circular centers) and noting whether they are equal in size. Check the white orbit of the eye for bloodshot.13
 
Nose
Check for signs of blood, clear fluid or a mixture of both, which might come from inside the skull.
 
Face
Look at the color—it may be pale, flushed or even bluish if breathing is affected. At the same time, feel the temperature of the face to check whether it is particularly hot or cold and note the state of the skin whether it is dry or clammy or even sweating profusely.
 
Ears
Check the ears for foreign bodies and traces of blood and/or clear cerebrospinal fluid that might indicate skull fracture. Speak into the casualty's ears to test hearing.
 
Skull
Gently run the hands over the scalp searching for bleeding, swelling or any indentation that might indicate a fracture.
 
Examining the Spine
Loosen clothing around the neck. Run your fingers over the spine from the base of the skull down to as far as you can reach between the shoulders, checking for any irregularity of the vertebrae that might indicate a fracture. Check round the neck, to see whether any warning medallion is being worn. Check the carotid pulse (Fig. 1.3), and note its rate, strength and rhythm. Note the presence or absence of movement or feeling in the casualty's limbs.

Examining the Lower Spine
Pass hand gently under the hollow of the back and without moving the casualty or removing 14any clothing. Feel along the spine as high and as low as you can there by checking for irregularity of the vertebrae or swelling.
 
Examining the Trunk
  • Check the chest for evenness of rib movement or breathing and note any wounds that are ‘sucking air’
  • Check the ribs for irregularity or depression that might indicate a fracture and also feel along the line of the breast bone
  • Check both collarbones for irregularity and the shoulders for signs of deformity. Carefully feel either side of the pelvis looking for signs of fracture and note any indication of incontinence.
 
Examining the Arms
Examine the upper arm bones, then the bones in the forearm, wrists, hands and fingers. Check carefully for any deformity and swelling, which might indicate fractures. Check the forearms to see if the casualty is wearing a medical warning bracelet and for injection marks. Needle marks might indicate either drug abuse or diabetes.
 
Examining the Legs
Check the hips, thighs, knee caps, both bones of the lower legs, the ankles, feet and toes in the same way as the arms.
 
LEVELS OF RESPONSIVENESS
There are various stages through which a casualty may pass during progression from consciousness to unconsciousness. If the casualty responds well to stimulation then unconsciousness is only light (e.g. as in a faint). However, he/she is still in a potentially dangerous state. If the response is poor or absent, the unconsciousness is deeper and the risk is correspondingly greater.
Every 10 minutes you should recheck and note the casualty's response to the stimuli of noise (speak loudly into the ear), touch 15(try to arouse by shaking the shoulders gently) and pain (watch the face, while you pinch the skin, or hand (ankle). In addition, you should keep a similar check on the casualty's breathing, pulse and temperature. Your findings should be recorded.
 
Aids to Diagnosis
Your diagnosis will be based on information from various sources. By taking the history of the incident, asking the casualty for symptoms and examining him/her for signs, it should be possible to make an accurate diagnosis. The following chart is a summary of how to achieve this.
 
History (Table 1.1)
History is obtained from surroundings, casualty and bystanders.
Table 1.1   History taking
Symptoms
Signs
These are the sensations experienced by the casualty and obtained by asking tactful questions:
  • Pain
  • Loss of normal movement
  • Loss of sensation
  • Cold
  • Heat
  • Thirst
  • Nausea
  • Weakness
  • Dizziness
  • Faintness

External Clues
If a casualty is unconscious, check their pockets, handbag or brief-case for possible clues. Appointment cards for a hospital or clinic or information cards may reveal that the casualty is on steroids or insulin or is liable to epileptic fits. Lumps of sugar or glucose present may even indicate that the casualty is diabetic (‘MedicAlert’). A locket for wrist or neck, a capsule, a neck chain or key ring containing a strip of paper may describe the casualty's condition.
 
Treatment
Carry out the appropriate treatment for each condition found gently and quickly. It is most important that to reassure and encourage the casualty constantly. Work calmly and efficiently. Pay attention to any remarks or request that the casualty makes, and do not pester with questions. This is annoying for the casualty and is a sign of uncertainty on your part. After giving the necessary treatment, place the casualty in the appropriate position and keep a watchful eye until help arrives. Bear in mind your aim is to preserve life, prevent the condition worsening and promote recovery.
 
To Preserve Life
  • Maintain an open airway by positioning the casualty correctly
  • Begin resuscitation, if the casualty is not breathing and the heart is not beating17
  • Continue treatment until skilled medical aid is available
  • Control bleeding.
 
To Prevent the Condition Worsening
  • Dress wounds
  • Provide comfortable support for any large wounds and fractures
  • Place the casualty in the most comfortable position consistent with the requirements of treatment.
 
To Promote Recovery
  • Relieve the casualty of anxiety and encourage confidence
  • Attempt to relieve the casualty of pain and discomfort
  • Handle the casualty gently
  • Protect the casualty from the cold and wet.
 
After Treatment
Once you have carried out your treatment the casualty should normally receive attention from a qualified person (doctor or nurse) without undue delay. Depending on the severity of the condition and the availability of skilled help you should:
  1. Arrange transportation to hospital by ambulance (or by car for minor injuries and arm fractures).
  2. Handover the casualty to the care of a doctor or nurse at the scene.
  3. Take the casualty to a nearby house or shelter to await the arrival of the ambulance or doctor.
  4. Allow the casualty to go home and advise him/her to seek medical advice, if necessary.
    Note: Never send anyone home who has been unconscious even for a short time or who is in shock; seek medical aid.
 
Making Report
The casualty should always be accompanied by a brief written report when he/she leaves your care. If necessary, you should accompany the casualty yourself and prepare personal report. The need to supply complete information cannot be emphasized enough and it should include the following:18
  • History of the accident or illness
  • Brief description of the injury
  • The level of responsiveness and any changes
  • Any other associate injuries
  • The pulse and any changes
  • The skin color and any changes
  • Blood loss sustained
  • Any unusual behavior by the casualty
  • Any treatment is given and when?
 
Informing Relatives
You should also send a tactful message to the casualty's home stating what has happened and where he/she has been taken if this has not already been done by the police or other authority attending the incident. If the casualty is unconscious or unable to tell you where to contact his/her relatives, look for a diary or donor card, which may give the relevant details (refer the topic ‘external clues’).
 
Property
Take care of any property belonging to the casualty and hand it over to the police or ambulance personnel.
 
Removing Clothing
Sometimes, it is necessary to remove clothing in order to expose injuries, make an accurate diagnosis or conduct a proper treatment. This should be done with the minimum of disturbance to the casualty and you should only remove as much as is actually necessary. Clothing should not be damaged unnecessarily. If very tight underclothing such as a girdle has to be cut, do this along the seams, if it is possible. Maintain sufficient privacy.
 
Removing a Coat or Jacket
Raise the casualty and slip the garment over his/her shoulders. Bend his/her arm on the sound side and remove the coat from that side first. Then slip the injured arm out of its sleeve, keeping the arm straight if possible. If necessary, slit up the seam on the casualty's injured side.19
 
Removing a Shirt or Vest
Remove a coat, if necessary slit it down the front or side.
 
Removing Trousers
Pull them down from the waist to reveal the casualty's thigh or raise the trouser leg to expose the calf and knee; if necessary slit up the inside seam.
 
Removing Boots or Shoes
Support the ankle, undo or cut any laces and carefully remove the shoe. If the casualty is wearing long boots, that will not unfasten, carefully slit them down the back seam with a sharp knife.
 
Removing Socks
If these are difficult to remove insert first two fingers between the sock and the leg. Raise the socks and cut it between the fingers with scissors.
 
Removing Crash Helmets
Whether or not you remove a protective helmet, such as motor cycle crash helmet, depends on the situation and condition of the casualty. It is best left on and should only be removed, if the casualty's condition warrants it. If possible, the helmet should be removed by the casualty. A full face helmet that encloses the head and face should only be removed, if it obstructs breathing, if the casualty is vomiting or if there are severe head injuries.
 
Removing an Open Face Helmet
Unfasten or cut through the chinstrap, if necessary. Take pressure off the head by forcing the sides apart, then lift the helmet upwards and backwards.
 
Removing a Full Face Helmet
To remove it safely, two people are needed, one to support the casualty's head and neck, while the other lifts the helmet:20
  1. Tilt the helmet back and gently lift until it is clear of the chin.
  2. Tilt the helmet forward to pass over the base of the skull, then lift it straight off.
 
POINTS TO REMEMBER IN FIRST AID
  • Ensure that there is no further danger to the casualty or yourself
  • Act quickly, quietly and methodically giving priority to the urgent conditions
  • If the casualty is unconscious, open the airway, check for breathing and complete the ABC of resuscitation if required, and place the casualty in the recovery position
  • Control bleeding
  • Minimize shock
  • Determine the casualty's level of responsiveness
  • Reassure the casualty to lessen anxiety
  • Position the casualty correctly and comfortably, but do not move more unless and until there is absolutely necessary
  • Consider the possibility of internal bleeding and poisoning
  • Treat large wounds and fractures before moving the casualty
  • If necessary, arrange for urgent transportation to hospital or into a doctor's care
  • Watch and record any changes
  • Do not attempt too much
  • Do not allow people to crowd around; this hinders first aid and may cause anxiety or embarrassment to the casualty
  • Do not remove clothing unnecessarily
  • Do not attempt to give anything via mouth to a casualty who is unconscious, who has a suspected internal injury or who may shortly need an anesthetic.
