| Popis: | Early respiratory support and airway (AW) control with endotracheal intubation (ETI) are crucial in mass toxicology events and must be performed while wearing chemical personal protective equipment (C-PPE).The aim of this study is to evaluate the efficiency of AW control by using second-generation supraglottic AW devices (SADs) as compared with ETI and first-generation SAD while wearing C-PPE.This is a randomized crossover trial involving 117 medical practitioners. Four AW management devices were examined: endotracheal tube, the first-generation SAD, laryngeal mask AW unique and 2 second-generation SAD, the laryngeal tube suction disposable, and supreme laryngeal mask AW (SLMA). Primary end point measured were success or failure, number of attempts, and time needed to achieve successful device insertion. Secondary end point was a subjective appraisal of the AW devices by study population.More attempts were required to achieve AW control with endotracheal tube, with and without C-PPE (P.001). Time to achieve AW control with ETI was, on average, 88% longer than required with other devices and improved with practice. The mean times to achieve an AW were longer when operators were equipped with C-PPE as compared with standard clothing. Subjectively, difficulty levels were significantly higher for ETI than for all other devices (P.0001).When compared with ETI, the use of SADs significantly shortened the time for AW control while wearing C-PPE. Second-generation SAD were superior to laryngeal mask AW unique. These finding suggest that SADs may be used in a mass toxicology event as a bridge, until definite AW control is achieved. |
