Brief Summary

The Endotracheal intubation (ETI) of a neonate is a procedure that usually attracts a large number of observers. The fear of being judged by others could cause an increased level of stress, especially on the junior trainees. Little research has focused on the effect of the audience on the level of stress and therefore, on the success rate of complicated procedures in neonatal intensive care.

Hypothesis:Investigators hypothesize that time to successful intubation (in seconds) will be longer with the presence of observers.

Detailed Description

Objective: The aim of this study will be to provide objective evidence supporting that junior trainees are less successful at neonatal ETI when in the presence of a large audience. If this hypothesis is correct, this data will provide evidence to support the residents request for less people around during the procedure, which may increase the chance of a successful intubation.

After Investigators obtained written consent - the selected student-will be asked to wear a cardiac monitor and 5 minutes later after a period of rest, they will be called in the delivery room. Two minutes after their arrival they will be given a stylet and a 3.5 ET tube and will be asked to intubate orally a mannequin, after 30 seconds, the operator will be reminded of the time. After 45 seconds the attempts will be stopped.

Participants will be informed of their right to discontinue participation at any time. The trainee will be informed at the end of the experience about the aim of the study and will be asked to keep it confidential.

The trainees will be randomized in two groups that differentiate in the conditions under which they will start the intubation.

Condition A: Only the staff will be present with the operator Condition B: An audience of 5 people with at least 2 neonatologists will be present in case of junior resident or the responsible of stage in case of respiratory therapy students.

The residents who performed intubation in condition A will do a repeat intubation 24 hours later using condition B and vice versa. The time and the local of the 2 procedures will be the same in both conditions.

Time to successful intubation will be compared between the two experimental conditions for each subject with paired t test. A p<0.05 will be considered significant.

To estimate the required sample size, Investigators used the study O'Donnel and al who gave an approximate intubation time for trainees of 38 seconds with standard deviation of 20 seconds (14). Using an alpha threshold of 0.05 and power of 80 %, a sample size of 51 subjects is required to detect 8 second difference time between the two different groups. Eight seconds represents a 25 % change in time to intubate and is clinically significant for a newborn.
