Brief summary

This study consists of a survey created for intensive care physicians regarding their current practice of the implementation of apnoea test for patients with suspected brain death.

Detailed description

Although the apnoea test is part of nearly all protocols for determining brain death; implementation significantly differs among intensive care physicians according to national-level acts, national society protocols or local protocols. This cross-sectional study is based on an international, web-based questionnaire created for intensive care physicians, consisting of 25 questions in English. The survey will provide a current state of the practice of apnoea testing in patients with suspected brain death. The results can support the determination of future acts to standardize the apnoea test process. The given answers are anonymous. The e-mail address of the respondent is not recorded. Answers are treated solely for scientific purposes.

Design outcomes

Primary

MeasureTime frameDescription
Number of apnoea testslast 1 yearHow much apnoea test is required for brain death determination.
Timeframe between apnoea testslast 1 yearIf more than 1 apnoeae test is reuired for brain death determination, how many hours should elapse between the two tests.
Preoxygenationlast 1 yearFor how long (in minutes) the patient is preoxygenated before the apnoea test.
Baseline arterial carbon dioxide (CO2) levelLast 1 yearWhat is the required arterial partial CO2 pressure (PaCO2) before apnoea testing, confirmed by arterial blood gas measurement?

Secondary

MeasureTime frameDescription
Detection of possible spontaneous breath movementslast 1 yearTo determine if any observation method other than visualisation by the observer is used to determine possible spontaneous breath movements during the apnoea test.
Satisfaction with current practicelast 1 yearSurveying the satisfaction of physicians with current practice regarding the method of the detection of spontaneous breath movements on a 4 grade scale (1 - non-reliable to 4 - very reliable).

Other

MeasureTime frameDescription
Continuous positive airway pressure (CPAP)last 1 yearIf a CPAP system is used during apnoea test, what is the value of positive end-expiratory pressure (PEEP) in H2Ocm.
