Abstract:
Objective:To investigate the efficacy and safety of a new airway opening device with automatic position adjustment.Methods:From January 4 to March 15,2021,the purposive sampling method was used to select 360 patients who underwent bronchoscopy exami-nation or treatment.According to the random sequence generated by a computer,the research assistant adjusted the position angle(PA)as 90°(90° PA group),95°(95° PA group),and 100°(100° PA group),respectively,to open the airway of subjects,and the bron-choscope entered the airway to obtain the image of the best glottic view.All subjects were followed up immediately after study and at 0.5,1,3,6,12,and 24 hours after study to observe device-related adverse events.The primary outcome measure was the Cormack-Lehane(CL)grade for glottic exposure,and the secondary outcome measures were the incidence rate of adverse events and Visual Ana-logue Scale(VAS)score.Results:More than 80.0%of the subjects had CL grade I glottic exposure,and there was no significant difference in CL grade between the three PA groups(x2=1.942,P>0.05).The CL grade of some subjects was optimized at an angle of 100°.No device-related adverse events were reported,and the VAS score was 0.Conclusion:The device can effectively and safely open the air-way of subjects undergoing bronchoscopy at a PA of 90°-100°,and although it has no obvious advantage in improving glottic exposure at different levels of PA,it is recommended to select the PA of 100° to open the airway.
