Brief Summary:

This is a survey of airway codes, which are emergency mobile phone requests for anaesthetic help to manage acute airway crises in the hospital (out of theatre, out of Surgical Intensive Care Unit, SICU).

The anaesthetists are doctors trained in advance airway management. Patients in the hospital may suffer airway crises e.g. airway obstruction or need for tracheal intubation (insertion of breathing tube) for various reasons. The on call SICU anaesthetists responds to the airway code by attending the patient in need and managing the patient at their own discretion.

Airway management will depend on the anaesthetist's knowledge, skills and experience. it will also depend on the available airway equipment.

We plan to evaluate airway codes for a 24 month period. Parameters include: type of incident; patient factors (including airway assessment); type of equipment used; anaesthetic drugs used; airway management chosen by the attending anaesthetist; and, airway complications.

Condition or disease
Intubation; Difficult

Detailed Description:

Airway codes will be managed as standard care. These calls are taken and managed by anaesthetists on call on SICU. The audit form is filled in by the on call anaesthetist after the airway code has been managed. This is an audit looking at:

Primary outcome

•Evaluate the type of airway codes that the SICU anaesthetist is called for

Secondary outcomes:

  • Patient factors (including airway assessment)
  • Type of equipment used
  • Type of anaesthetic drugs used
  • Airway management chosen by the attending anaesthetist
  • Airway complications.

Primary Outcome Measures :
  1. Survey the type of airway codes that the SICU anaesthetist is called for [ Time Frame: One hour post calling of airway code ]
    Cause of airway codes i.e. respiratory arrest or indication for formal airway management by anaesthetist

Secondary Outcome Measures :
  1. Survey of types of equipment needed for airway management [ Time Frame: One hour post calling of airway code ]
    Type of equipment used include airway bag, bougie, videolaryngoscope

  2. Number of participants with predictors of difficult airway [ Time Frame: One hour post calling of airway code ]
    Predictors of difficult airway include small mouth opening, short thyromental distance, prominent upper teeth, receding lower jaw, decreased neck movement, previous surgery, previous radiotherapy
