Abstract

PURPOSE
Personal protection equipment (PPE) is compulsory for the safety of physicians and patients in the presence of biological hazards. In particular, such equipment is required for airway management of patients with highly contagious respiratory diseases. However, there are only a few studies about the effect of PPE on airway management with various advanced airway devices including the newly developed video-laryngoscope. We conducted a study on the effect of PPE level C on airway management with five different types of advanced airway devices including the laryngeal mask airway (LMA), direct laryngoscope (DL), airwayscope (AWS), video-laryngoscope made by Stortz (DCI), and the Levitanscope (LE).
METHODS
Twenty-two emergency physician and residents in two emergency centers were trained to do trials with PPE and without PPE while performing airway management with five different airway devices. The procedures were done on two types of manikins. We compared the time from the start of the procedure to the first successful ventilation for each device and for each type of manikin. A short questionnaire was used to examine participants' subjective experiences.
RESULTS
For both types of manikin, there were no significant differences in performance time between the group not wearing PPE and the PPE wearing group for any device. However, when compared with the other devices, the performance time for the LMA was faster than the other devices, and the Levitanscope(R) took a significantly longer time in both groups. According to the questionnaires, the most comfortable & uncomfortable airway devices were the LMA and the Levitanscope(R).
CONCLUSION
When PPE level C was compared with the no protection state, there were no significant statistical time differences for performing advanced airway management with any particular airway device.
