目的 研究和分析外科Ⅲ类手术切口术后感染的危险因素,达到进一步预防外科Ⅲ类手术切口术后感染的目的。方法 研究对象为我科2014年1月—2016年12月普外科的1 816例Ⅲ类手术切口患者,以术后是否发生切口感染为因变量,以性别、年龄、是否切口贴用医用薄膜、切口是否碘伏冲洗等相关因素为自变量,进行Logistic回归分析,统计分析外科Ⅲ类手术切口术后发生感染的危险因素。结果 1 816例外科Ⅲ类手术切口中,术后发生切口感染有218例,切口感染率为12%。单因素分析显示,8项影响因素与Ⅲ类手术切口术后感染具有相关性(P﹤0.01),对具有统计学意义的8影响因素进行多因素Logistic回归分析,结果显示手术切皮前应用薄膜保护切口、术后切口碘伏冲洗及合理应用抗生素为切口感染保护因素(P﹤0.01),而患者年龄、全麻、急诊手术、输血及住院时间为切口感染独立危险因素(P﹤0.01)。结论 手术皮肤切开前应用医用薄膜、关腹后碘伏冲洗伤口对降低Ⅲ类手术切口术后感染发生率有一定效果,值得临床推广。

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 分析慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)合并肺动脉高压(pulmonary hypertention,PH)的危险因素。方法 回顾2014年1月—2015年1月广州医科大学附属第一医院住院患者55例,经心脏彩色多普勒超声测量肺动脉收缩压(PASP),分为:轻度组(36≤PASP＜50 mmHg),中度组(51≤PASP＜70 mmHg)和重度组(PASP≥70 mmHg),分析比较三组临床特征,危险因素采用单因素及多因素Logistic回归分析。结果 年龄(75.3±11.6)岁,PASP为(52.6±15.1)mmHg。单因素分析中-重度PH与年龄、HCT、PaCO₂、PaO₂、D-二聚体有关;多因素Logistic回归分析确定3项危险因素:HCT[比值比(OR)=51.82,95% CI: 2.34～1149.02],RV(OR=4.53,95% CI: 2.83～7.27),及PaCO₂(OR=1.02,95% CI: 1.00～1.03)。结论 呼吸病相关PH多为轻-中度,高水平的HCT、RV直径及PaCO₂提示PH病情较重。

Objective To analyze the clinical risk factors of pulmonary hypertension (PH) associated with chronic obstructive pulmonary disease(COPD). Methods A total of 55 hospitalized patients from 2014 to 2015 were enrolled in the study and were classified into three groups according to pulmonary artery systolic pressure (PASP) with echocardiography as follows: the mild group (36≤PASP＜50 mmHg), the moderate group (51≤PASP＜70 mmHg) and the severe group (PASP≥70 mmHg). Clinical data were recorded and retrospectively analyzed. Results The average age of all patients was (75.3±11.6)years. Echocardiography showed a mean PASP was 52.6±15.1 mmHg. Age, hematocrit (HCT), partial pressure of carbon dioxide (PaCO₂), the oxygen partial pressure (PaO₂), D-dimer and right ventricular (RV) diameter (>20 mm) were associated with moderate-to-severe PH on an univariate regression analysis, while RV (diameter >20 mm)[odds ratio (OR)=4.53, 95% CI: 2.83～7.27], HCT(OR=51.82, 95% CI: 2.34~1149.02) and PaCO₂ (OR=1.02, 95% CI: 1.00-1.03), to these patients, were independent risk factors using the multiple logistic regression analysis. Conclusion PH related to respiratory diseases is mostly mild-to-moderate. Haemoptysis,high levels of RV diameter, HCT and PaCO₂ suggest a serious condition of patients with PH related to chronic respiratory disease.

目的 比较胆总管切开探查术后留置T管和胆总管切开探查并一期缝合术后胆管内支架引流这两种模式治疗胆管疾病的手术疗效。方法 对2012年—2014年期间收治的90例需择期行胆总管探查的患者进行前瞻性随机对照研究。按照实验方式分为T管组40例和单管内支架组50例。对比分析两组胆总管置管缝合手术时间、住院时间、治疗总费用、生活质量指数值以及并发症发生率,包括引流失败率(T管滑脱、内支架管滑脱、移位)、胆漏、胆道感染、胰腺炎和残石率。结果 开腹胆总管探查术术后内支架引流患者的出院前生存质量评价高于T管引流患者,住院时间少于T管引流患者,置管及胆管缝合时间长于T管引流患者(均为P＜0.05);术后两组患者间的治疗总费用和非计划脱管、胆漏、胆道感染、胰腺炎、残石率和不能拔/脱管等术后并发症发生率的差异无统计学意义(P＞0.05)。结论 内镜下胆道支架内引流术(Endoscopic retrograde biliary drainage,ERBD)移植于胆总管切开探查并一期缝合术具有可行性、安全性及治疗效果确切,显著缩短患者住院时间、加快患者康复提高患者出院前的生存质量,并放宽胆总管一期缝合指征。

Objective To compare the clinic research between biliary stent insertion drainage and T-tube drainage after choledochotomy. Methods The clinical data of 90 cases from 2012 to 2014 were analyzed in a prospectively randomized trial, and they were divided into two groups by T-tube drainage and biliary stent insertion drainage. Cathetering and suture time, length of stay, hospital costs, life quality and incidence of complications were compared, respectively. Results After open common bile duct exploration (OCBDE), the life quality of stent group was significantly higher than that of T-tube group, the length of stay in stent group was shorter, and cathetering and suture time of bile duct in stent group was longer than that of T-tube group (P＜0.05); There were no significant differences between the two groups in the hospital costs and incidences of postoperative complications including bile leakage, early stent dislodgement, biliary infection, pancreatitis and residual stone (P＞0.05). Conclusion Endoscopic retrograde biliary drainage (ERBD) with primary closure after choledochotomy is a safe, effective and feasible procedure for the management of choledocholithiasis, it can significantly reduce the postoperative hospital stay and improve the life quality of patients and expand the indications for primary closure of CBD incision.
