First Aid Tips

Managing a suspected Spinal Injury.

Creating further damage when dealing with a suspected spinal injury is always a great concern for first aiders.

The vertebrae is in 5 sections and contains 28 bones (some of these are fused to create a “joined bone”) and of course supports and protects the spinal cord which is carrying signals from the brain to different parts of the body.

If the injured person is conscious and can give symptoms of the pain eg: tingling in the hands, feet, or worse no sense of felling at all leave them on their back or in the position you have found them, avoid any movement of their vertebrae assisting with immobilisation if possible. If you are trained to do so and the equipment is available apply a neck brace or collar for support, constantly monitor their A.B.C and treat for shock while you are waiting for the professionals.

If the injured person is unconscious we should still be concerned about the movement of the vertebrae and must manage the causality with as much care as possible but in this case the causality must be rolled onto their side into the lateral position ensuring spinal alignment as this is don

The reason the unconscious causality must be moved is that there is a greater risk of blocking of the airway by their tongue or aspirating (choking on their vomit) when left on their back which will result in suffocation of the causality. The A.R.C (Australian Resuscitation Council) states that “airway management must take precedence over ever other condition including spinal damage”.

Managing a Thermal Burn

When the skin has been opened through cutting or burns the body is at a high risk of infection. When managing any injury it is important to ensure that part of the management includes infection control. If possible always use clean, hygienic, equipment including bandaging. An ideal method of infection control for a burn is using a plastic wrap like “Cling Film” from the kitchen. Make sure it is not applied to tight as you should expect some swelling from fluid retention from the burn. Burns should be ran under cool running water for at least 20 minutes or until the professionals arrive to give assistance.

Managing a Fracture

A fracture may not always be obvious. If a casualty is showing signs and symptoms including pain, swelling, loss of movement of a limb, deformity you should suspect a fracture and manage by immobilising.

Immablisation can be done with very simple tools. A fracture to a forearm can be managed by just resting it on a pillow on top of a table while waiting for the ambulance or supported by lifting their shirt up and pinning it above the forearm.

If possible part of immobilising the fracture may include “splinting”. Splints can be made by using simple household items like a rolled up newspaper or magazine, rolled towel or even another body part.

When splinting it is important to ensure that the splint is longer enough to go past the joint of the limb it is also important to keep checking the finger tips or toes for signs of restricted circulation.

Acute Myocardial Infarction
A myocardial infarction — or acute myocardial infarction — is a complete blockage of the coronary artery, which carries blood to the myocardium (heart muscle wall). The blockage often is a result of a blood clot, but can also be caused by plaque (cholesterol) or other material. A myocardial infarction leads to heart muscle death and may cause decreased heart output. Victims of acute myocardial infarction are at risk for sudden cardiac arrest and death.

Condition in which the heart has stopped or is too weak to pump effectively. A casualty suffering a cardiac arrest will be unconscious, unresponsive to verbal commands and touch, not breathing normally and not moving. Infrequent gasps of air may be seen in a witnessed cardiac arrest. However, this is not an indication of effective breathing. The three most common conditions that lead to cardiac arrest are ventricular fibrillation, ventricular tachycardia and Asystole. Casualties of cardiac arrest do not have enough circulation to maintain blood flow to the brain. Irreversible brain damage and death will usually occur within four minutes of the onset of cardiac arrest. Cardiopulmonary resuscitation (CPR) and defibrillation are the only treatments for cardiac arrest.

The fight or flight response is a catch-all phrase describing the body’s response to stress. Fight or flight refers to the two choices our ancestors had when facing a dangerous animal or enemy. In that moment of stress (fear) the body prepares itself to be injured and to expend energy in the large muscle groups of the arms, legs and shoulders that we use to either fight or run (flight).

Flail Chest
Refers to a section of the rib cage that has broken away from the surrounding ribs. Usually, more than one rib is involved, and they are broken in at least two places. Flail chest typically is the result of blunt chest trauma and is more common in the elderly. These segments of broken ribs got the name flail chest because the segments flail back and forth opposite from the rest of the chest wall. In other words, as the rest of the chest expands to suck in a breath of air, the flail chest segment sucks in. During exhalation, when the rest of the chest contracts, the flail chest segment bulges out. Often, a grinding sound or feeling called crepitus goes with the flailing segment.

Movement of air in and out of the lungs by inhaling and exhaling; during breathing.
Respiratory Arrest
The absence or cessation of breathing. In most cases, casualties of respiratory arrest are also suffering from cardiac arrest, and should receive CPR.

Every healthcare provider has a scope of practice, except physicians. Physicians have the ability to develop new skills as necessary. For example it is in the paramedic scope of practice to give injections through muscle, under skin or directly into a vein. Paramedics are not usually licensed to suture wounds.
