Objective: To research and analyze the risk factor which lead to type Ⅲ operation incision infection,and prevent the incision infection.Methods: The clinical data of 1816 typeⅢoperation incision patients from the general surgery department during 2001-2016,With incision infection serving as a dependent variable, gender, age, using medical films, rinsing the incision with iodophor after the abdomen closing and other factors as independent variables, single factor analysis and logistic regression analysis were used to identify risk factor for typeⅢoperation incisions.Results: From 1816 typeⅢoperation incision patients,218 patients suffered from incision infection with a infection rate of 12%,Single factor analysis showed that 8 factors had significant effects on infection of type Ⅲ operation incision(P<0.01). Logistic regression analysis showed that there were 8 related factors out of 9 factors,and age,anesthesia,blood transfusion,the days of hospitalization and emergency surgery were possible independent risk factors of incision infection(P<0.01), and the critical pathway,using medical films,rinsing the incision with iodophor after the abdomen closing,reasonable use of antibiotics were protective factors against incision infection(P<0.01),while age,anesthesia,blood transfusion,the days of hospitalization and emergency surgery were possible independent risk factors of incision infection(P<0.01).Conclusion: Using medical films before the skin incising, rinsing the incision with iodophor after the abdomen closing can reduce the rate of incision infection postoperation, it is worthy of clinical promotion.

目的 分析神经营养类药物单唾液酸四己糖神经节苷脂(monosialotetrahexosylganglioside,GM1)与胞磷胆碱(citicoline)联合使用在新生儿缺血缺氧性脑病(neonatal hypoxic-ischemic encephalopathy,NHIE)的临床疗效并探讨其可能的作用机制。方法 收集2014年1月—2017年6月在广州市第一人民医院新生儿病房住院的54例新生儿缺血缺氧性脑病患儿的临床资料,将收集到的患儿随机分为2组,对照组27例,治疗组27例。治疗组与对照组的治疗的不同在于前者予以单唾液酸四己糖神经节苷脂GM1联合胞磷胆碱治疗,而对照组仅用单唾液酸四己糖神经节苷脂GM1,无用胞磷胆碱。治疗三个疗程后,比较2组用药前后的临床表现、神经功能评分及MRI变化情况。结果 治疗组中临床总有效24例(88.9%);对照组中总有效17例(63.0%)(P<0.05);经过三个疗程后2组的神经功能评分均有上升,且治疗组的效果更明显(P<0.05);MRI检查示2组较用药前病灶范围减少,水肿减轻,治疗组改善更明显(P<0.05)。即经过三个疗程治疗后,两组患儿病情均有好转,且治疗组疗效更明显。结论 神经营养类药物GM1联合胞磷胆碱通过修复、重构神经元、改善其代谢等促进受损的神经功能的恢复,在新生儿缺血缺氧性脑病的应用中具有良好的疗效。
