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

Comparison of Glidescope, Pentax-AWS and Macintosh Laryngoscope for Intubation During Chest Compression in 15-30 Degree Left-Lateral Tilt: A Manikin Simulation Study of Maternal Cardiopulmonary Resuscitation

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.
