Purpose . Rapid advanced airway management is important in maternal cardiopulmonary resuscitation (CPR). This study aimed to compare intubation performances among Pentax-AWS (AWS), Glidescope (GVL), and Macintosh laryngoscope (MCL) during mechanical chest compression in 15° and 30° left lateral tilt.  Methods . In 19 emergency physicians, a prospective randomized crossover study was conducted to examine the three laryngoscopes. Primary outcomes were the intubation time and the success rate for intubation.  Results . The median intubation time using AWS was shorter than that of GVL and MCL in both tilt degrees. The time to visualize the glottic view in GVL and AWS was significantly lower than that of MCL (all  P  < 0.05), whereas there was no significant difference between the two video laryngoscopes (in 15° tilt,  P  = 1; in 30° tilt,  P  = 0.71). The progression of tracheal tube using AWS was faster than that of MCL and GVL in both degrees (all  P  < 0.001). Intubations using AWS and GVL showed higher success rate than that of Macintosh laryngoscopes.  Conclusions . The AWS could be an appropriate laryngoscope for airway management of pregnant women in tilt CPR considering intubation time and success rate.
