双套管负压持续引流治疗胃肠术后腹腔感染的临床研究

Clinical effect of double cannula continuous negative pressure drainage on treatment of abdominal infections after gastrointestinal surgery

目的探讨双套管负压持续引流治疗胃肠术后腹腔感染的临床效果,以期提高临床治疗水平。方法以2011年3月-2013年1月90例胃肠术后腹腔感染患者为研究对象,平均分为两组,对照组45例予以传统的乳胶引流,观察组45例则予以双套管负压持续引流治疗,比较两组治疗后的效果情况;采用SPSS13.0软件进行分析。结果共检出病原菌36株,对照组24株占66.67%,观察组12株占33.33%;其中对照组、观察组均以金黄色葡萄球菌为主分别占33.33%、13.89%,其次为大肠埃希菌、鲍氏不动杆菌、肺炎克雷伯菌、真菌;引流液变清时间、拔管时间、置管时间、住院时间、平均引流量、二重感染率观察组分别为(5.53±1.83)d、(9.54±4.68)d、(10.28±4.36)d、(17.95±8.58)d、(158.94±23.74)ml/d、2.22%,对照组分别为(7.64±2.23)d、(15.82±6.63)d、(14.84±5.37)d、(23.78±1.85)d、(100.45±17.46)ml/d、11.11%,两组比较差异有统计学意义(P<0.05)。结论双套管负压持续引流能减少胃肠术后腹腔感染的发生率,缩短引流时间,临床效果满意。

OBJECTIVE To explore the clinical effect of the double cannula continuous suction drainage on the treatment of abdominal infections after gastrointestinal surgery so as to improve the level of clinical treatment.METHODS From Mar 2011to Jan 2013,totally 90patients with postoperative abdominal infections who underwent the gastrointestinal surgery were enrolled in the study and divided into two groups,then the 45cases in the control group were treated with the conventional latex drainage,while the 45cases in the observation group were given the double cannula continuous suction drainage;the therapeutic effect was observed and compared between the two groups,and the statistical analysis was performed with the use of SPSS13.0software.RESULTS A total of36strains of pathogens have been isolated,including 24（66.67%）strains isolated from the control group and 12（33.33%）strains isolated from the observation group;the Staphylococcus aureus was the predominant species of pathogens in the both the control group（33.33%）and the observation group（13.89%）,followed by the Escherichia coli,Acinetobacter baumannii,and Klebsiella pneumoniae.The time of the drainage fluid＇turning to be clear was（5.53±1.83）days in the observation group,（7.64±2.23）days in the control group;the time of extubation was（9.54±4.68）days in the observation group,（15.82±6.63）days in the control group;the time of catheter indwelling was（10.28±4.36）days in the observation group,（14.84±5.37）days in the control group;the hospitalization duration was（17.95±8.58）days in the observation group,（23.78±1.85）days in the control group;the mean drainage volume was（158.94±23.74）ml/d in the observation group,（100.45±17.46）ml/d in the control group;the incidence of superinfection was 2.22%in the observation group,11.11%in the control group;there were significant differences between the two groups（P〈0.05）.CONCLUSION The double cannula continuous suction drainage can reduce the incidence of abdominal infections after the gastrointestinal surgery and shorten the drainage time so as to achieve satisfactory clinical effect.
