First Aid: The Modern Way
by Tom Trimble, Nov 1996

[Tom Trimble, an emergency room nurse at UCSF,
came to Freeborn Hall on Thursday, 7 Nov 1996,
to speak on the topic of First Aid. This is the
handout that he prepared for those who attended the course.]

What is First Aid?
"What to do until the Doctor comes . . ." is now what to do to keep the victim alive, or prepare him for further treatment, until emergency medical services take over or medical care can be gotten.

What�s important?
Recognizing life-threatening problems, taking immediate action to save life, preventing further injury, accessing emergency medical services efficiently, following through on health care needs.

What are the really dangerous things?
Any time there is

  • unconsciousness
  • difficulty breathing
  • the heart�s beating doesn�t "seem" right ---too fast, too slow, too irregular, too hard to feel
  • bleeding is fast and hard to stop
  • or an overdose or poison has been taken,
    things can get bad very rapidly and the person may die before help arrives.

    What lifesaving acts must one know how to do?

  • How to open the airway.
  • How to assist breathing.
  • How to do CPR.
  • How to stop bleeding.
  • How to get help. Call 911.

    What are ABCs?
    ABCs are: the Airway; the Breathing; and the Circulation. The first things to check and to constantly ensure to keep the patient alive. If nothing else is done, these essentials are the most likely to save life.

    What about Airway?
    An open path or tube for air to actually reach the lungs when the patient breathes or is helped to breathe is essential. If someone chokes on food or vomit, the airway can be clogged so that air cannot flow and the lungs can be damaged by inhaled fluids. When a person is unconscious (cannot be easily woken), the body relaxes and slumps more than usual. The tongue, especially, then being about four ounces of floppy meat can sag making it difficult for air to fight its way through: the person may be snoring or even not moving any air at all.

    Getting the tongue out of the way is done by lifting the neck and tilting the head backwards, and pulling the chin or jaw upwards, so that the front of the neck is stretched tight. This pulls on the attachments of the tongue and other tissues and opens the airway. If the patient is capable of breathing on his own, he can do so now; he can then be turned on his side with the head supported in this position so that any drool or vomit can drain. If he does not move his own air, one can now breathe for him with mouth-to-mouth or mouth-to-nose artificial respiration.

    What about Breathing?
    If he breathes fully and sufficiently on his own with ease and seems OK, ---watch him and keep him that way.

    If he is awake, seems to be choking and can�t talk, and clutches his throat in a universal sign of distress, ---he may need to have a Heimlich maneuver done until he can move air or you can breathe air for him into his lungs.

    If he does not breathe on his own or his efforts are feeble, he will need to have you assist or replace his breathing with your own. (You may use a CPR pocket mask or face shield, or cover his mouth and nose with a handkerchief or layer of T-shirt. With the airway stretched open, and having taken a full breath, place your mouth around his mouth or nose with a good seal, and blow in smoothly until the chest makes a nice easy rise from your breath; stop; turn away and watch the chest smoothly fall; and repeat twelve times a minute for adults (every 5"), twenty times a minute for children (every 3"), and thirty times a minute (every 2") for babies. Have someone call for help.

    What about Circulation?
    If breathing is OK, or is being done for him, check the pulse to make sure the heart is beating and blood is being pumped. If you check carefully, and can�t feel a pulse, then chest compressions will need to be added to the mouth-to-mouth to provide CPR -- Cardio-Pulmonary-Resuscitation. Activate 911.

    What about Bleeding?
    The most effective way to stop bleeding is to press hard right where the blood is coming from and don�t let go. Think of the story of "the little Dutch boy with his finger in the dike" who saved his whole country from being flooded by the North Sea by plugging the leak. It will also help if you can also have the victim lie down, and raise the bleeding part well above heart level.

    What about getting help?
    Emergency help can usually be gotten by calling 911. No coin is needed. Cellular phones in California have 911 calls answered, at present, by the Highway Patrol rather than a local operator: you will need to know how to clearly describe your address or location if using a cell-phone.! Some locations such as the UC Campus may have special reporting numbers to call. Major public locations and some streets may have fire-alarm boxes or emergency telephones. Learn the special methods for any location that you frequent.

    What about broken bones and other injuries?
    Let the victim keep himself in any position in which he is comfortable. Injured arms can be tied to the chest and legs can be tied to the other one for extra support with a little padding in-between. The aim is to provide comfort and prevent further injury by keeping the broken bone ends and the joints above and below from moving.

    If the accident involved massive force, move the person as little as is necessary to save life, until rescuers arrive. Open wounds and burns can be covered to keep them clean.

    How does one know if the bone is broken?
    If the break is not obvious by deformity or angulation, the key finding is "point tenderness" along the path of the bone, e.g., it hurts to touch and pressure where the injury is. If the part hurts to move or bear weight, it should be rested and protected.

    What about muscle strains and joint sprains?
    These stretching-tearing injuries to "soft tissues" of muscle and gristle can be due to sudden excessive force beyond the usual range of motion. They can be taken care of with "R-I-C-E":

  • Rest -- Avoid using it; the "micro re-injury" with each use before pain is gone will slow the healing.
  • Ice -- Ice it frequently for 20-30 minutes at a time during the first 48 hours to slow the cascade of inflammatory chemicals from the injury, ease pain, and limit swelling.
  • Compression -- An elastic wrap may feel comfortable and limit swelling, but with higher grade sprains it may be necessary to have a protective splint from the doctor; sometimes, even a plaster cast or surgery may be needed.
  • Elevation -- Gravity can be put to work decreasing swelling and the throbbing ache that goes with it by elevating the injured part above the heart (just putting your ankle out in front of you on a footstool doesn�t do it) so as to drain away the accumulated fluid.

    What about Overdoses and Poisonings?
    If unconscious, do only the ABCs and get help. Call the SF Bay Area Regional Poison Control Center: 1 (800) 523-2222 for specific help and advice, if at all uncertain of what to do.

    When does a cut need stitches?

  • If the cut seems to go all the way through the skin so that fat or other structures underneath can be seen
  • if the edges gape or can be spread apart
  • if it is unusually dirty or ragged
  • if the shape of the wound crosses the natural "lines" in the skin
  • if it is a "bite" wound (whether human or animal)
  • if it is in an area of constant movement or crosses a joint
  • if it is caused by a penetrating object
  • if there is any change of sensation, movement, or strength
  • any time that you are not sure

    What about Tetanus?
    Tetanus is a horrible and deadly disease that is completely preventable and has been designated "the inexcusable disease." Immunization should be every ten years for your entire life, and a booster vaccination may be given anytime there has been a risky wound or status is uncertain.

    The germ is "everywhere" and in wounds where there is little air, gives off a toxin that attacks the spinal nervous system so that body-bending convulsions occur, in which one is perfectly awake, until one stops breathing or the back is broken. It is very difficult to treat.

    What First Aid Supplies are needed?
    Mainly knowledge and willingness. Bandages and splints can be improvised. A CPR pocket mask or face shield, and vinyl or latex gloves are desirable. While neckties, Kotex�, and panty-hose can all be used to give first aid, some sterile dressings and bandages are good to have. Clean non-fuzzy cloth can be substituted.

    Disorders of Consciousness
    Regardless of the cause of unconsciousness, the first aider has the job of protecting the patient from the dangers of being unconscious.

  • He must be protected from further injury and the accident kept from getting worse.
  • His ABCs must be safeguarded.
  • He must be kept reasonably warm and comfortable, lying in a recovery position where his airway is tilted open and drainage of saliva or vomit can occur
  • He must be taken to medical care, preferably by an ambulance.

    In healthy young adults, the commonest causes of unconsciousness are self-induced intoxication with alcohol, narcotics, and sedatives; simple faints; epileptic convulsions; and forceful injury to the brain.

    Simple faints usually occur through several mechanisms when the heart�s output decreases to less than that needed to perfuse the brain with blood carrying oxygen and nutrients. Classic examples are sudden intense physical discomfort or emotional distress putting the brakes on the heartrate and the blood vessels dilating so that blood pressure drops. When the victim lies down (or falls), he recovers naturally as it takes less pressure to perfuse a person lying down than one who is upright.

    Seizures are the convulsions that occur in epilepsy and other malfunctions of the brain�s electrical circuitry; ---not seizure and possession by demons . "He doesn�t act right" or interact with other people, and possibly uncontrolled stiffness and shaking of major muscle groups of the body. It�s hard to breathe because of the tightness of the muscle spasms so his face may turn first pale then dark. He might be hurt in falling or hitting things. The teeth and jaw might be clamped shut bite injuries happen to the victim and to his rescuer. He might pee, poop, or puke uncontrollably. As the seizure ends, the patient "sleeps" for a while, then wakens, perhaps gradually, usually without memory for the event.

  • Safeguarding the victim from injury is all that is needed.
  • Try to remember the time, how long the duration, and the sequence of events.
  • Don�t try to hold him down which might cause injury but, instead, cradle his head.
  • Put nothing into the mouth or between the teeth (you might break his teeth or other injury, or be hurt yourself).
  • If the seizure continues without let-up, or repeated seizures occur without waking up, than immediate ambulance treatment is necessary.

    Head Injury: This is the term for when the working of the brain has been temporarily or permanently altered by an injury. The danger is not whether there has been a "concussion" or even a "skull fracture" but whether progressive or permanent injury has occurred to the brain inside. Because there is no extra room inside the closed skull for an injured brain to expand as it swells from injury, unrelenting swelling can lead to unrelenting pressure on the brain and death.

    Man would never have evolved without surviving many lesser injuries yet the cumulative effects of many small injuries can be bad as in the sad case of Muhammed Ali.

    Burns: The largest organ of the body and the one that most protects us from the environment is the skin. If a large portion of our corporal envelope is damaged, the stress and decreased ability to regulate our internal environment may kill us.

    Regardless of the physical agent causing the "burn", whether thermal (wet = scald, dry = burn e.g. flame, contact); radiant energy such as ultraviolet from the sun, "radiation" from atomic energy, x-rays, microwaves; electrical or lightning; or chemical, such as strong acids or alkalis; ---the effect is to denature or coagulate proteins in the tissues i.e. the albumin egg white is cooked. Further, the amount and degree of injury may progress and become worse as a result of the burning agent itself or of subsequent infection. The body, and even Life, may be severely stressed or overcome by serious burns.

    Which burns are minor and which are major ---requiring immediate 911 response and treatment en route to a burn or trauma center? Minor burns, (the ordinary touch of a hot pot) can often be self-treated at home by cooling the burn, a non-stick airtight dressing and bandage, and simple pain relievers such as Ibuprofen, Aspirin, or Acetaminophen.

    Serious or Major burns are:

  • those to either young children or to elders
  • may not hurt very much as they have burned the entire thickness of the skin, even in a small area, and have killed the nerve endings that tell of pain
  • cover a substantial portion of the body (even a wide-area "sunburn" may need treatment)
  • affect important structures like the hands or feet, eyelids, ears, or lips, crossing joints
  • any burn from electrical energy (there may be internal injury not yet visible as the current coursed through the body along blood vessels or nerves)
  • any inhaled burn such as steam, smoke inhalation or toxic substances, any cough or shortness of breath, singed or sooty nose hairs, or has occurred from being in an enclosed space such as a car or bedroom fire (can cause serious difficulty with breathing, airway swelling, or poisonous inhalation)
  • any burn where the patient has been unconscious for any reason whatsoever, or seems greatly overcome by his injuries
  • any burn where there is clothing burned into the wound or embedded objects, the victim is covered with a contaminating chemical, or other non-burn injuries have occurred.

    With serious burns such as these, little first aid needs to be done other than to

  • remove from the cause of the burn and protect from further injury
  • keep the airway open and the patient breathing, if need be in the position that he finds most comfortable
  • prevent the burn from getting dirty by covering the burns with a clean sheet
  • keep him reasonably warm, lying down, and comfortable.

    For minor and "in-between" burns, cool the burn (this stops a "soft-boiled egg" burn from becoming a "hard-boiled egg" burn) by immersing it in water or covering it with clean wet cloths for 15-20 minutes, then wrap it airtight with a clean tight-weave cloth such as pillow cases or sheets. Go soon to the nearest appropriate hospital emergency department, to have the burn examined, cleaned and dressed, and for medicines to relieve pain and prevent infection.
