中心静脉导管加持续低负压吸引治疗自发性气胸的临床疗效分析

目的探讨中心静脉导管加持续低负压吸引治疗自发性气胸的临床应用价值及可行性。方法对我科2004年4月至2007年5月98例自发性气胸患者随机分组，分为治疗组49例和对照组49例。治疗组采用中心静脉导管置入胸膜腔加持续低负压吸引治疗，对照组采用传统胸腔闭式引流术治疗。观察比较两组的平均肺复张时间、平均住院天数、治愈率及并发症发生率（皮下气肿、复张性肺水肿、穿刺部位感染）。结果肺复张时间及治愈率治疗组与对照组无明显差异，平均住院天数治疗组比对照组减少，并发症发生率治疗组比对照组明显降低。结论采用中心静脉导管加持续低负压吸引治疗自发性气胸，方法简单、易操作、创伤小、效果好、费用低．值得临床推广。

Clinical efficacy of central venous catheter plus lasting vacuum aspiration for the treatment of spontaneous pneumothorax

Objective To retrospectively analyze the clinical efficacy and reliability of central vein catheter plus lasting vacuum aspiration for the treatment of spontaneous pneumothorax. Methods Ninety - eight cases of spontaneous pneumothorax treated in our hospital from April 2004 to May 2007 were divided into two groups. Forty - nine cases in the treatment group were treated with central vein catheter plus lasting vacuum aspiration, traditional pleura cavity closed type drainage was applied in 49 cases in the control group. There were no significant differences between the treatment group and the control groups in age, the degree of lung compression, the type of pneumothorax, the mean length from the occurrence of pneumothorax to intubation and other aspects of adjuvant therapy. The average time of lung recruitment, the average length of hospital stay, the cure rate and the incidence of complications （ subcutaneous emphysema, reexpansion pulmonary edema and puncture site infection） were compared between the two groups. Results There was no obvious difference in lung recruitment for squeezing time and the cure rate between the treatment group and control group. The average length of hospital stay and the incidence of complications in the treatment group were obviously decreased compared to the control group respectively. Conclusion The method by using central venous catheter plus lasting vacuum aspiration to treat spontaneous pneumothorax is worthy of clinical promotion for its easy manipulating, less trauma, more effective and lower cost.
