Coopdech封堵支气管导管用于食管癌手术单肺通气的临床观察

Clinical observation of Coopdech bronchial blocker tube in patients underwent resection of esophageal carcinoma with one - lung ventilation

目的评价Coopdech封堵支气管导管用于食管癌手术患者单肺通气（OLV）的效果。方法选取需行OLV的食管癌手术患者30例，随机分为双腔支气管导管组（A组，n=15）和封堵支气管导管组（B组，n=15），比较两组患者插管定位时间、术中肺萎陷情况、插管前后心率和血压变化及OLV时PaCO2、PaO2、SpO2、pH和气道压力（PAw）的变化。结果B组插管定位时间低于A组，插管后A组MAP、HR升高，OLV30分钟、60分钟时B组PaO2明显高于A组，而PAW低于A组，同时两组SpO2、PaCO2、pH无明显差异。结论Coopdech封堵支气管导管能够为食管癌手术提供有效的OLV。

Objective To evaluate the feasibility of Coopdech bronchial blocker tube in patients underwent resection of esophageal carcinoma with one - lung ventilation （OLV）. Methods Thirty ASA I or II patients were divided into two groups （n = 15 each） ： catheter with double tubes group（group A, 15 cases） , Coopdech bronchial blocker tube group（ group B, 15 cases）. The following variables were recorded： 1 ） time to initially position the assigned tube, 2） overall surgical exposure, 3 ） BP and HR, and 4） PaCO2 、PaO2 、SpO2 、Pressure difference between alveoli and mouth （PAW） at 30 min and 60 min after OLV. Results Group A took longer to place compared with group B. There was no statistical difference in lung collapse between the two groups. In group A, BP and HR increased significantly after intubation as compared with the baseline before intubation （P 〈 0. 05）. PaO2 was significantly higher and PAW was significantly lower at 30 min and 60 min after OLV in group B than in group A. There was no significant changes in PaCO2 and SpO2. Conclusions It is feasible to use the Coopdech bronchial blocker tube to attain rapid and secure lung isolation in patients underwent resection of esophageal carcinoma.
