Endotracheal Intubation Using Three Laryngoscopes in Maternal Cardiac Arrest: a Manikin Simulation Study

Not Applicable

Completed

• Conditions: Cardiac Arrest
• Interventions: Device: 15 degree left-lateral tilt wedges; Device: 30 degree left-lateral tilt wedges

• Registration Number: NCT02074072
• Lead Sponsor: Hanyang University Seoul Hospital

Brief Summary

European Resuscitation Council (ERC) Guidelines for Resuscitation 2010 emphasize high quality chest compressions .They propose minor changes for pregnant women: manual left deviation of the uterus or a left-lateral incline of 15-30to alleviate pressure on the inferior vena cava. We will examine the performance of the Glidescope (GVL), the Pentax-AWS Airwayscope(AWS) and Macintosh laryngoscope (McL) for airway management during chest compressions on 15 and 30 degree left-lateral tilt (15 \&30 LLT) custom-made hard wedges.

Arm && Interventions

Group	Intervention	Description
Direct laryngoscope	15 degree left-lateral tilt wedges	Macintosh laryngoscope
Direct laryngoscope	30 degree left-lateral tilt wedges	Macintosh laryngoscope
Videolaryngoscope-1	15 degree left-lateral tilt wedges	Glidescope
Videolaryngoscope-1	30 degree left-lateral tilt wedges	Glidescope
Videolaryngoscope-2	15 degree left-lateral tilt wedges	Airwayscope
Videolaryngoscope-2	30 degree left-lateral tilt wedges	Airwayscope

Primary Outcome Measures

Name	Time	Method
Time to intubation	1day	We will check the times from inserting blade to mouth to exposing vocal cord and from exposing vocal cord to first ambu-bagging.
Success rate of intubation	1day	Definition of failed intubation; * Time to intubation is longer than 90 seconds.; * Wrong placement of endotracheal tube (For example : Esophageal intubation etc.)

Secondary Outcome Measures

Name	Time	Method
Laryngeal View during intubation	1day	We will record the best laryngeal View during intubation. We will record according to the Cormack-Lehane Grade system.
The preference for laryngoscopes	1day	1. The preference for laryngoscope regardless of tilting degree of wedges; 2. The preference for laryngoscope in 15 degree left-lateral tilt situation .; 3. The preference for laryngoscope in 30 degree left-lateral tilt situation . (Participants will select only 1 of 3 laryngoscopes and the preference will be displayed as histogram)
