Abstract:ObjectiveTo explore the application value of visual double-lumen bronchial catheter in pulmonary isolation.Methods60 patients with one lung ventilation assisted by video-assisted thoracoscopic surgery who were treated in our hospital from October 2016 to February 2017 were selected as subjects.They were randomly divided into fiberoptic bronchoscopy group(group F)and visual double lumen bronchial catheter group (group VD),with 30 cases in each group.Patients in group F were positioned with the help of fiberoptic bronchoscopy,and patients in group VD were positioned with the help of visible double lumen bronchial catheter.The catheter positioning time,the number of catheter displacement during operation,the number of adverse events caused by catheter displacement in group F and VD were recorded (poor collapse of the lung on the operation side affected the operation field,insufficient ventilation on the healthy side,atelectasis,etc.),and the positioning time was readjusted after catheter displacement.ResultsThe localization time of group VD was shorter than that of group F,there was no significant difference between the two groups(P<0.05).The incidence of adverse events in group VD was lower than that in group F (P<0.05).The repositioning time of group VD after catheter displacement was significantly shorter than that in group F,the differents was satistically significant(P<0.05).ConclusionThe visual double-lumen bronchial catheter is superior to the fiberbronchoscope in the catheter positioning and continuous monitoring.It has a good application prospect in the lung isolation technology.
