左侧卧位下右支气管封堵器定位的应用

选取电视胸腔镜下右进胸食管癌根治术患者40例,随机分为平卧位组(S组)和左侧卧位组(L组),每组20例.两组患者均在麻醉诱导后插入气管导管,然后在纤维支气管镜引导下置入右侧支气管封堵器.S组患者处于平卧位时由纤维支气管镜引导置手并定位,L组患者在左侧卧位时由纤维支气管镜引导下置入并定位.观察比较两组患者支气管封堵器移位情况、纤维支气管镜使用次数以及肺萎陷满意率.S组侧卧位封堵器移位次数以及平卧位时需用纤维支气管镜的次数较L组明显增多,而肺萎陷满意率两组相比差异无统计学意义.左侧卧位下纤维支气管镜引导右侧主支气管置入支气管封堵器,其具有减少侧卧位移位发生和减少纤维支气管镜的使用次数等优点,值得推荐于临床实践.

Use of right bronchial occluder placement and positioning under left-lateral position

40 patients to undergo video-assisted thoracoscopic radical resection of esophageal carcinoma through right thoracotomy were randomly divided intogroup of horizontal position (group S) and group left lateral position (group L),and with 20 patients in each group respectively.The bronchial occluder was placed into the right bronchia guided by fiber bronchoscope after tracheal intubation following the anesthesia induction in each group,while the occluder of group S was placed under the left lateral position,while that of group L was inserted under horizontal position.Then,we observed including the occluder displacement,the number of the use of fiber bronchoscope and the satisfaction degree of pulmonary collapse in the two groups.The differences of the occluder displacement number under lateral position,the number of the use of fiber bronchoscope in the two groups were statistically significant,while there was no statistical difference in the satisfaction degree of pulmonary collapse between the two groups.The fiber bronchoscope-guided bronchial occluder placement into the right bronchia under left-lateral position is able to prevent the displacement during lateral position process and reduce the number of use of fiber bronchoscope,which is deserved to be recommended into the clinical practice.
