Abstract
Background
Emergency airway management in suboptimal conditions can result in difficulties in
tracheal intubation. The video laryngoscope (Pentax-AWS®) has potential advantages during difficult tracheal intubations. According to the
2005 guidelines for cardiopulmonary resuscitation (CPR), all rescuers should minimize
interruption of chest compressions. Our hypothesis is that tracheal intubation using
the Pentax-AWS® is possible without interruption of chest compressions. We tested this using tracheal
intubation performed by less experienced medical personnel in a manikin model.
Methods
Thirty-two less experienced (<10 tracheal intubations) medical interns performed intubation
using the Pentax-AWS® and the Macintosh laryngoscope in an ALS simulator (Laerdal, Stavanger, Norway) in
each of three scenarios. The three scenarios were: (1) normal airway without chest
compression, (2) normal airway with continuous chest compression, and (3) difficult
airway with continuous chest compression. The success rate, time required to complete
tracheal intubation and to visualize vocal cords, POGO (percentage of glottic opening)
score, dental compression and the ease of intubation were recorded.
Results
All participants performed successful intubation with the Pentax-AWS® in the three scenarios. In the two continuous chest compression scenarios (scenarios
2 and 3), the success rate was significantly higher with the Pentax-AWS® than with the Macintosh laryngoscope.
Conclusions
The Pentax-AWS® was an effective tool for endotracheal intubation during chest compression performed
by less experienced medical personnel in a manikin model simulating cardiac arrest,
both under conditions of normal and difficult airways.
