外科手术患者发生手术部位感染的手术室相关因素及预防措施研究

Study on Related Factors and Preventive Measures of Operating Room Infection in Surgical Patients

目的探究外科手术患者发生手术部位感染的手术室相关因素及预防措施。方法试验者均是方便选取在2019年6-11月间该院收治的86例外科手术患者,将2019年6-8月间收治的45例外科手术患者作为对照组(未实行手术室预防措施),将2019年9-11月间收治的41例外科手术患者作为观察组(实行手术室预防措施),分析外科手术患者出现手术部位感染的手术室影响因素,并对比两组患者手术后住院时间、住院费用和感染率。结果外科手术患者出现手术部位感染的手术室相关因素包括手术时间、手术切口、空气细菌含量、非流层手术以及参观人数;观察组患者手术后住院时间(0.84±0.23)周、住院费用(1.31±0.28)万元均明显较对照组(2.07±0.62)周、(2.68±0.69)万元更低,差异有统计学意义(t=8.732、7.651,P<0.05);观察组患者手术部位感染率14.63%明显较对照组37.78%更低,差异有统计学意义(χ^2=11.004,P<0.05)。结论手术时间过长、手术切口、空气细菌含量高、非流层手术以及参观人数多均可在一定程度上引起外科手术患者出现切口感染现象,临床据此实施一系列预防措施,能够有效缩短患者住院时间,降低住院费用,减少手术部位感染发生率。

Objective To explore the related factors and preventive measures of surgical site infection in surgical patients.Methods conveniently selected 86 surgical patients admitted to the hospital as test subjects from June to November 2019,and 45 surgical patients admitted from June to August 2019 were used as the control group(no implementation of precautions in operating room),41 surgical patients admitted between September and November 2019 were taken as observation group(precautions in operating room were implemented),and the factors influencing surgical site infections in surgical patients were analyzed.The hospitalization time,hospitalization expenses and infection rate after surgery were compared between the two groups.Results The operating room related factors of surgical site infection in surgical patients included operating time,surgical incision,air bacteria content,non-flow layer surgery,and the number of visitors;the observation group was hospitalized(0.84±0.23)weeks after surgery and hospitalization expenses(1.31±0.28)ten thousand yuan were significantly lower than those in the control group(2.07±0.62)weeks and(2.68±0.69)ten thousand yuan,and the difference was statistically significant(t=8.732,7.651,P<0.05);the surgical site infection rate of the observation group was14.63%significantly lower than the control group 37.78%,the difference was statistically significant(χ^2=11.004,P<0.05).Conclusion Excessive operation time,surgical incision,high air bacteria content,non-flow layer surgery,and large number of visitors can all cause incision infection in surgical patients to a certain extent.Based on this,a series of clinical preventive measures can be effectively shortened the length of the patient’s hospital stay,the reduction of hospitalization costs,and the reduction of the incidence of surgical site infections.
