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 the curative effect of self-made negative pressure drainage device in preventing incision infection after cesarean section. Methods 120 cases of cesarean section were randomly divided into observation group and control group, 60 cases in each group. Postoperative self-made negative pressure drainage catheter placed in the observation group, postoperative conventional suture patients as a control group, postoperative patients were routinely rational use of antibiotics. The incision infection and wound healing time were compared between the two groups. Results There were no significant differences in age, gestational age, operation time and intraoperative blood loss between the two groups (P> 0.05). In the observation group, there were 6 cases of incision swelling after cesarean section, the incidence rate was 10.0%. The incision infection was in 2 cases, the incidence rate was 3.3% and the incision healing time was 7.12 ± 2.56 d. In the control group, there were 15 cases of incision redness after cesarean section, the incidence rate was 25.0%. There were 8 cases with incision infection, the incidence rate was 13.33% and the incision healing time was 11.76 ± 3.67 days. Two groups of incision swelling, incision infection, incision healing time difference was statistically significant (P <0.05). Conclusion Self-made negative pressure drainage device can effectively reduce the incision infection rate and shorten the incision healing time after cesarean section, which can be promoted clinically.
