STUDY OBJECTIVE: To evaluate the effectiveness, safety, ease of placement, and ventilatory parameters of a new alternate airway device, the EasyTube (EzT; Teleflex Ruesch, Research Triangle Park, NC), in comparison to the endotracheal tube (ETT). DESIGN: Prospective, randomized controlled trial. SETTING: University Hospital. SUBJECTS:200 adult ASA physical status I and II patients scheduled for surgery. INTERVENTIONS: Patients were randomized to two groups, one to receive ventilation via the EzT (n = 100) or the ETT (n = 100). After preoxygenation and induction with fentanyl and propofol, patients received muscle relaxation. The respective airway device was then inserted and mechanical ventilation was instituted. MEASUREMENTS: Ease of insertion, number of insertion maneuvers, time until airtight seal of the airway was achieved, duration of surgery, leak pressure as well as arterial oxygen saturation (SpO(2)), and end-tidal carbon dioxide (ETCO(2)) data, were recorded. MAIN RESULTS:Mallampati airway class was higher in the EzT group (P < 0.029), while thyromental distance showed no difference between the two groups. Ease of insertion was noted in the EzT group (P < 0.043). Number of insertions was equal in both groups; insertion time was shorter with the EzT (15.5 +/- 3.6 sec vs. 19.3 +/- 4.6 sec; P < 0.0001). Leak pressure and SpO(2) were not significantly different, while ETCO(2) was lower with the ETT (P < 0.024). Adjustments had to be made for two EzT group patients. No difference in frequency of laryngo-pharyngeal discomfort was observed in either group. CONCLUSION: Insertion of an EzT appears to reduce time and facilitate placement of an airway device when compared with direct laryngoscopy and tracheal intubation.
