Prospective randomized comparison of the EasyTube and the esophageal-tracheal Combitube airway devices during general anesthesia with mechanical ventilation

Inter-center comparison of EasyTube and endotracheal tube during general anesthesia in minor elective surgery

“…The most important finding of our study is that insertion, ventilation, hemodynamics, and oxygenation of the EzT were comparable to the ETT and did not differ significantly between the sites. This is in accordance with overall results from other studies [14, 15, 17, 18]. We further show for the first time that there is a significant difference in rate of complications, leakage, and in difficulty of insertion amongst the different sites.…”

“…We therefore expected higher ventilatory pressures in the EzT group. However, peak and mean airway pressures were in accordance to previously reported data [14, 18], but lower than reported for the Combitube [21]. Also, we did not observe a significant change in peak or mean airway pressure compared to baseline as reported by Sethi [14].…”

“…Also, training in airway management is similar though not standardized worldwide. The observed insertion success rates for the EzT and ETT were comparable to other studies (Sethi 87% [14], Gaitini 92.5% [18], Lorenz 95% [15], Cavus 64% [13], Park [19]).…”

The EasyTube during general anesthesia for minor surgery

“…This is in accordance with previous results. [13,14,25,26] To our knowledge, this represents the biggest study population and the only multicenter-study with the utilization of the EzT during general anesthesia to date.…”

The Development and Application of Airway Devices in China

“…An esophageal-tracheal combi-tube [12] is a kind of emergency airway device that combines the esophageal-blocking function as well as the tracheal ventilation function as a supraglottic airway. It is usually used to tackle with difficult ventilation and difficult intubation during emergency.…”
