Clinical Trial Summary

In a non-randomized, controlled, cross-over simulation study, the investigators evaluated and compared intubation performance of trained operators, using either a conventional laryngoscope in an ice-pick position or a video laryngoscope in a free-floating classic position, in weightlessness and in normogravity.

Data were analyzed with the generalized linear mixed-effects models.

Primary endpoint was the success rate of tracheal intubation. Time to intubation and the confidence score into the success of tube placement were also recorded as secondary endpoints.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	First pass success	Bi-pulmonary ventilation success was assessed by the intubating operator performing chest auscultation and by the measurement of a tidal volume on the mannequin's electronic sensors. Selective side intubation was considered as failure	1 day (1 flight)
Secondary	Time	The duration (seconds) of each attempt was recorded and ended with vocal confirmation of tube placement from the intubating operator or at the end of the parabola	1 day (1 flight)
Secondary	Confidence Score	A subjective score of confidence in the correct tube placement was recorded after each attempt and ranked from minus ten (complete certainty about failure) to plus ten (complete certainty about success). A score of zero was pronounced by the operator when he/she had maximum uncertainty about success or failure.	1 day (1 flight)
