Abstract
We have previously reported the utility of the Pentax-AWS Airwayscope® (AWS) as an intubation device during chest compressions at one institution. To validate and generalize the utility of AWS, we investigated tracheal intubation time during cardiopulmonary resuscitation (CPR) in manikins using Macintosh laryngoscope (McL) or AWS in 34 difficult airway management (DAM) workshop students and task forces from various institutions. In the McL trial, time to secure the airway was significantly longer in a chest-compression situation than in a non-chest compression situation (15.0±3.3 sec vs 20.7±10.2 sec, P‹0.01). In the AWS group, significant differences between chest compression or non-chest compression were not observed. The success rate of the tracheal intubation in McL was significantly lower than that of AWS (P‹0.01). AWS training may lead to the emergent intubation in the situation of CPR.
