Intervention effect of operating room environmental management on postoperative infection rate
手术室环境管理对术后感染率的干预效果

摘要

目的 探究多维度手术室环境管理方案对术后感染率的干预效果。方法 选取2024年9月-2025年9月在兴安盟人民医院接受择期手术的100例患者为研究对象，均符合年龄30-50岁、体重指数（BMI）20-25kg/m²、文化程度初中及以上的纳入标准，采用随机数字表法分为对照组（50例）与实验组（50例）。对照组实施常规手术室环境管理，实验组实施多维度环境管理方案。两组均随访至术后7d，比较术后感染率、环境质量指标及患者满意度。结果 实验组术后感染率显著低于对照组（χ2=5.316，P=0.021）；实验组术中平均浮游菌浓度、术后环境清洁达标率优于对照组（t=18.035，χ2=8.333，P均＜0.05）；实验组患者满意度）高于对照组（χ2=5.765，P=0.016）。结论 多维度手术室环境管理通过全周期、精细化管控，可有效降低术后感染率，提升环境质量与患者满意度，值得在临床推广应用。

Abstract

Objective To explore the intervention effect of a multi-dimensional operating room environmental management plan on the postoperative infection rate.
Methods A total of 100 patients who underwent elective surgery at Xing'an League People's Hospital from September 2024 to September 2025 were selected as the research subjects. All patients met the inclusion criteria: aged 30-50 years, body mass index (BMI) 20-25 kg/m², and education level of junior high school or above. They were divided into a control group (50 cases) and an experimental group (50 cases) using a random number table method. The control group implemented conventional operating room environmental management, while the experimental group adopted a multi-dimensional environmental management plan. Both groups were followed up for 7 days after surgery, and the postoperative infection rate, environmental quality indicators, and patient satisfaction were compared between the two groups.
Results The postoperative infection rate of the experimental group was significantly lower than that of the control group (χ2=5.316, P=0.021); the average concentration of planktonic bacteria during surgery and the compliance rate of postoperative environmental cleaning in the experimental group were better than those in the control group (t=18.035, χ2=8.333, all P<0.05); the patient satisfaction of the experimental group was higher than that of the control group (χ2=5.765, P=0.016).
Conclusion   Multi-dimensional operating room environmental management, through full-cycle and refined control, can effectively reduce the postoperative infection rate, improve environmental quality and patient satisfaction, and is worthy of clinical promotion and application.
