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

Outcome Measures
Primary Outcome Measures
- 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
- 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]
The preference for laryngoscope regardless of tilting degree of wedges The preference for laryngoscope in 15 degree left-lateral tilt situation . 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)
