Recovery position

Recovery position
Intervention

All forms of the recovery position share basic principles. The mouth is downward so that fluid can drain from the patient's airway; the chin is well up to keep the epiglottis opened. Arms and legs are locked to stabilize the position of the patient

The recovery position refers to one of a series of variations on a lateral recumbent or three-quarters prone position of the body, in to which an unconscious but breathing casualty can be placed as part of first aid treatment.

An unconscious person, a person who is assessed on the Glasgow Coma Scale (GCS) at eight or below ≤8, in a supine position (on the back) may not be able to maintain an open airway as a conscious person would.[1] This can lead to an obstruction of the airway, restricting the flow of air and preventing gaseous exchange, which then causes hypoxia, which is life-threatening. Thousands of fatalities occur every year in casualties where the cause of unconsciousness was not fatal, but where airway obstruction caused the patient to suffocate.[2][3][4] The cause of unconsciousness can be any reason from trauma to intoxication from alcohol.

It is not necessarily used by health care professionals, as they may have access to more advanced airway management techniques, such as intubation.

Purpose

The recovery position is designed to prevent suffocation through obstruction of the airway, which can occur in unconscious supine patients. The supine patient is at risk of airway obstruction from two routes:

Placing a patient in the recovery position gives gravity assistance to the clearance of physical obstruction of the airway by the tongue, and also gives a clear route by which fluid can drain from the airway.

The International Liaison Committee on Resuscitation does not recommend one specific recovery position, but advises on six key principles to be followed:[5]

  1. The casualty should be in as near a true lateral position as possible with the head dependent to allow free drainage of fluid.
  2. The position should be stable.
  3. Any pressure of the chest that impairs breathing should be avoided.
  4. It should be possible to turn the victim onto the side and return to the back easily and safely, having particular regard to the possibility of cervical spine injury.
  5. Good observation of and access to the airway should be possible.
  6. The position itself should not give rise to any injury to the casualty.

History

The earliest recognition that placing unconscious patients on their side would prevent obstruction of the airway was by Robert Bowles, a doctor at the Victoria Hospital in Folkestone, England.[5] In 1891 he presented a paper with the title 'On Stertor, Apoplexy, and the Management of the Apoplectic State' in relation to stroke patients with noisy breathing from airway obstruction (also known as stertor).

This paper was taken up by anaesthetist Frederick Hewitt from the London Hospital who advised a sideways position for postoperative patients. This thinking was, however, not widely adopted, with surgical textbooks 50 years later still recommending leaving anaesthetised patients in a supine position.[5]

First aid organisations were similarly slow in adopting the idea of the recovery position, with 1930s and 1940s first aid manuals from the British Red Cross and St John Ambulance both recommending lying a patient on their back. The 1938 British Red Cross First Aid Manual goes so far as to instruct "place the head in a such as position that the windpipe is kept straight, keeping the head up if the face is flushed, and in line with the body if it is pale".[6] By contrast, the St. John manual advocated turning the head to the side, but it was not until the 1950 40th edition of the St. John Manual that it was added "if breathing is noisy (bubbling through secretions), turn the patient into the three-quarters prone position",[5] which is very similar to a modern recovery position.

A large number of positions were experimented with, mostly in Europe, as the United States did not widely take up the recovery position until its adoption by the American Heart Association in 1992.[5] Positions included the "Coma Position", "Rautek's Position" and the "HAINES (High Arm IN Endangered Spine) position".

In 1992, the European Resuscitation Council adopted a new position where the arm nearest the floor was brought out in front of the patient, whereas it had previously been placed behind the patient. This change was made due to several reported cases of nerve and blood vessel damage in the arms of patients.

ILCOR made its recommendations on the basic principles for recovery positions in 1996, but does not prescribe a specific position, and consequently, there are several in use around the world.
