目的:探讨负压引流在急诊剖腹探查术的切口感染预防工作的意义.方法:对2020年6月至2021年3月我科收治的98例急诊剖腹探查术患者进行随机对照研究,分为对照组和负压组,统计两组患者的一般资料、手术资料、术后炎症因子强度、切口感染及治疗时间、换药时间及费用等,分析比较两组的差异并进行亚组分析.结果:负压组切口感染的比例较对照组低,但差异无统计学意义,两组炎症因子差异无统计学意义,亚组分析中,肥胖患者和长切口的患者,负压组切口感染比例小,感染后换药时间短,差异具有统计学意义.结论:切口负压引流在预防急诊剖腹“,”Objective: To investigate the significance of negative pressure drainage in the prevention of incision infection in emergency exploratory laparotomy.Methods: in June 2020 to May 2021, our department treated 98 cases of emergency laparotomy surgery patients randomized controlled study, divided into control group and negative pressure drainage group, two groups of patients with general statistics, operation data, the strength of postoperative inflammation factors, infection of incision, and the treatment time, treatment time and cost, etc., analysis and comparing the difference between the two groups of subgroup analysis.Results: The proportion of incision infection in the negative pressure drainage group was lower than that in the control group, but the difference was not statistically significant. The difference of inflammatory factors between the two groups was not statistically significant. In the subgroup analysis, for obese patients and patients with long incisions, the proportion of incision infection in the negative pressure drainage group was lower, and the dressing change time after infection was shorter, the difference was statistically significant.Conclusion: The incision negative pressure drainage has certain significance in the prevention of incision infection in patients with emergency laparotomy, which is worthy of clinical promotion.
