自制负压引流器在预防剖宫产术后切口感染中的应用体会

Application experience of self-made vacuum drainage apparatus in prevention of postoperative incision infection in cesarean section

目的探讨自制负压引流器在剖宫产术后预防切口感染中的疗效。方法 120例行剖宫产手术患者,随机分为观察组和对照组,每组60例。术后切口放置自制负压引流器患者作为观察组,术后行常规缝合患者作为对照组,术后两组患者均常规合理使用抗生素治疗。比较两组患者术后切口感染情况及切口愈合时间。结果两组年龄、孕周、手术时间及术中出血量比较差异无统计学意义(P>0.05)。观察组剖宫产术后出现切口红肿6例,发生率为10.0%,切口感染2例,发生率为3.3%,切口愈合时间(7.12±2.56)d。对照组剖宫产术后切口红肿15例,发生率25.0%,切口感染8例,发生率13.33%,切口愈合时间(11.76±3.67)d。两组切口红肿、切口感染、切口愈合时间比较差异均有统计学意义(P<0.05)。结论自制负压引流器对剖宫产术后患者可以有效的降低术后切口感染率,并缩短切口愈合时间,可在临床推广。

Objective To investigate curative effect by self-made vacuum drainage apparatus in prevention of postoperative incision infection in cesarean section. Methods A total of 120 patients in cesarean section were randomly divided into observation group and control group, with 60 cases in each group. The observation group received postoperative self-made vacuum drainage apparatus placement in incision, and the control group received conventional postoperative suture. Both groups received general antibiotic therapy after operation. Comparison was made on postoperative incision infection status and incision healing time between the two groups. Results There was no statistically significant difference of age, gestational weeks, operation time and intraoperative bleeding volume between the two groups （P〉0.05）. In the observation group, there were 6 cases with incision inflammation after cesarean section, with incidence as 10.0%, and 2 cases with incision infection with incidence as 3.3%, and it had incision healing time as （7.12 ± 2.56） d. In the control group, there were 15 cases with incision inflammation after cesarean section, with incidence as 25.0%, and 8 cases with incision infection with incidence as 13.3%, and it had incision healing time as （11.76 ±3.67） d. The difference of incision inflammation, incision infection, and incision healing time had statistical significance between the two groups （P〈0.05）. Conclusion Self-made vacuum drainage apparatus can effectively lower postoperative incision infection rate and shorten incision healing time, and it is worth clinical promoting.
