肺上叶切除术后单根胸管持续负压引流的临床分析

Clinical Analysis of Continuous Negative Pressure Drainage by Single Chest Tube in Patients with Upper Lung Lobe Resection

目的探讨肺上叶切除术后单根胸管持续负压吸引引流对残腔闭合的影响。方法将2002年1月至2012年6月间在沧州市人民医院接受肺上叶切除的138例患者随机分成两组,试验组66例,采取单根胸管引流新型胸瓶持续负压吸引;对照组72例,采取上下双胸管引流普通胸瓶不接负压吸引,观察胸腔残腔闭合情况。结果试验组的术后平均残腔气液平面存留数少于对照组,且差异有统计学意义(χ2=4.87,P<0.05);试验组和对照组的术后胸腔平均引流总量分别为560mL和1000 mL,比较差异有统计学意义(χ2=7.75,P<0.01)。结论采用单根胸管引流新型胸瓶持续负压吸引的术后残腔闭合时间和引流量均优于上下双胸管引流普通胸瓶不接负压吸引的方式。

Objective To discuss the influence of pulmonary lobectomy single chest tube continuous negative pressure suction drainage on residual cavity closing. Methods 138 cases of lung lobectomy patients from People＇s Hospital of Cangzhou during Jan. 2002 and Jun. 2012 were randomly divided into 2 groups. Group A （trial group,66 cases） ：single chest tube drainage novel chest bottles sustained suction, Group B （control group ,72 cases） ：up and down double chest tube drainage ordinary chest bottle without suction;the residual cavity closure situation was observed. Results The mean postoperative residual gas-liquid surface of the residual caity of the trial group was less than the control group with statistically significant difference （Χ^2 =4.87 ,P 〈0.05 ）; the average total postoperative chest drainage of the trial group and control group was 560mL and 1000 mL respectively, the difference was statistically significant （Χ^2 = 7.75, P 〈 0.01 ）. Conclusion Single chest tube drainage novel thoracic bottle continuous suction in postoperative drainage is superior to the upper and lower double chest tube drainage ordinary chest bottle without suction in both resid- ual cavity closing time and drainage amount.
