Effect of Using Endotracheal Tube Introducer for Intubation During Mechanical Chest Compressions in a Manikin

Not Applicable

• Conditions: Intubation, Intratracheal; Advanced Cardiac Life Support
• Interventions: Device: Macintosh laryngoscope; Device: Endotracheal tube introducer

• Registration Number: NCT04116333
• Lead Sponsor: Derince Training and Research Hospital

Brief Summary

The aim of this study was to compare the impact of using ETI with the Macintosh laryngoscope on first pass success rates of the final year students of medical school on a manikin during continuous chest compressions with mechanical compression device.

Detailed Description

Fifty-two final year students of Kocaeli University Medical School will participate to the study. The participants will complete the one-hour training lecture on the use of the Macintosh laryngoscope (ML) and the endotracheal tube introducer (ETI) that will be instructed by an emergency medicine specialist. The information section will be followed by a chance of practice each endotracheal intubation method once by using the ML with and without the ETI on the manikin.

Mechanical compression device will be used to perform chest compressions. The manikin will be placed on an ambulance stretcher in a supine position. Airway interventions will be performed in a sitting position on a seat that will be adjusted to the same height with the ambulance seat. The airway kit will be placed beside the head of the manikin.

Each participant will perform 2 airway interventions. Participants will be allowed for maximum 2 attempts for each method. Each procedure will be recorded to the video camera. The participants will be aware of the video camera. Following the interventions each participant will be asked to grade the difficulty of the both methods on a 5-point Likert scale defined as 1: very easy, 2: easy, 3: moderate, 4: difficult and 5: very difficult. The participants will be asked for whether they have prior clinical experience or not with ML or/and ML with ETI use.
