持续负压吸引延长带管时间对颈部淋巴结核术后切口的影响

Effects of continuous negative pressure aspiration and prolonged drainage on the incision of patients with cervical lymph node tuberculosis after operation

目的探讨持续负压吸引延长带管时间对颈部淋巴结核术后切口的影响。方法回顾性分析132例颈部淋巴结核术后引流情况按引流方式分为2组,治疗组92例,采用持续负压吸引延长带管时间的引流方式;对照组40例,采用橡皮片或引流管的引流方式。比较2组患者术后引流量、术后住院时间、术后带管时间、切口愈合不良率、术后复发率、切口舒适度等指标。结果2组术后住院时间分别为(20.63±12.14)d、(17.87±5.51)d,差异无统计学意义(t=1.375,P>0.05)。术后引流量分别为(82.80±45.11)ml、(141.99±80.65)ml,差异有统计学意义(t=-5.368,P<0.05);术后带管时间分别为(6.15±2.66)d、(14.95±2.87)d,差异有统计学意义(t=-16.371,P<0.05),术后切口愈合不良率对照组为27.50%,治疗组为9.78%,差异有统计学意义(χ^2=6.087,P<0.05)。术后复发率对照组为17.50%,治疗组为10.87%,差异无统计学意义(χ^2=1.092,P>0.05)。2组切口舒适度差异有统计学意义,(Z=-7.911,P<0.05)。结论持续负压吸引延长带管时间可以降低颈部淋巴结核术后切口感染率,是适合颈部淋巴结核手术的引流方式。

Objective To investigate the effects of continuous negative pressure aspiration and prolonged drainage on the incision of patients with cervical lymph node tuberculosis after operation.Methods A total of 132 patients with cervical lymph node tuberculosis who were treated by surgery in our hospital were divided into observation group(n=92)and control group(n=40).The patients in observation group were treated by continuous negative pressure aspiration and prolonged drainage,however,the patients in control group were treated by rubber tissue or suction tube drainage.The postoperative drainage volume,postoperative hospital stay,postoperative tube indwelling duration,the incidence of bad incision healing,postoperative relapse rate and incision comfort degree were observed and compared between the two groups.Results There was no significant difference in the postoperative hospital stay between the two groups(P>0.05).There were significant differences in the postoperative drainage volume and postoperative tube indwelling duration between the two groups(P<0.05).There was no significant difference in postoperative relapse rate between the two groups(P>0.05),however,there was significant difference in the incision comfort degree between the two groups(P<0.05).Conclusion The continuous negative pressure aspiration and prolonged drainage can decrease the incidence of wound infection in patients with cervical lymph node tuberculosis after operation,which is suitable drainage mode for these patients.
