Study 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.

Read the 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.

What researchers measure

Primary outcomes

  1. Number of apnoea tests

    How much apnoea test is required for brain death determination.

    Time frame: last 1 year

  2. Timeframe between apnoea tests

    If more than 1 apnoeae test is reuired for brain death determination, how many hours should elapse between the two tests.

    Time frame: last 1 year

  3. Preoxygenation

    For how long (in minutes) the patient is preoxygenated before the apnoea test.

    Time frame: last 1 year

  4. Baseline arterial carbon dioxide (CO2) level

    What is the required arterial partial CO2 pressure (PaCO2) before apnoea testing, confirmed by arterial blood gas measurement?

    Time frame: Last 1 year

Secondary outcomes

  1. Detection of possible spontaneous breath movements

    To determine if any observation method other than visualisation by the observer is used to determine possible spontaneous breath movements during the apnoea test.

    Time frame: last 1 year

  2. Satisfaction with current practice

    Surveying 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).

    Time frame: last 1 year

Other outcomes

  1. Continuous positive airway pressure (CPAP)

    If a CPAP system is used during apnoea test, what is the value of positive end-expiratory pressure (PEEP) in H2Ocm.

    Time frame: last 1 year

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
