体外循环浅低温心脏不停跳心内直视手术的临床研究

目的:探讨体外循环浅低温心脏不停跳心内直视手术的方法、疗效评价及其对心肌保护作用。方法:总结2004年3月～2008年12月间12例施行浅低温心脏不停跳心内直视手术病例,并行循环不阻断主动脉,鼻咽温维持在32～35℃,阻断上、下腔静脉,完成心内直视手术。结果:全组无围手术期死亡,心脏手术结束能顺利停机,术后血流动力学平稳,无严重心律失常,血尿发生率0%,无1例发生空气栓塞。1例心房切口缝合针眼渗血,行再次开胸止血,1例术后第32h发生急性肺梗塞,均经治疗痊愈。结论:浅低温心脏不停跳心内直视手术技术安全可行,是一种接近生理状态的心肌保护方法,可避免再灌注损伤,有较理想的心肌保护效果。     

Mortality rate after hip hemiarthroplasty: analysis of risk factors in 299 consecutives cases

Abstract The femoral neck fracture is actually the most important traumatic event in the elderly, because of its high rate and terrible complications. We reviwed clinical records of 314 patients treated in our institution with a bipolar implant for femoral neck fracture. At a mean follow-up of 5 years, 15 patients (4.8%) were lost to followup so data for 299 patients was studied to identity factors associated with mortality. Ten predictor variables were examined: age, sex, waiting time for surgery, pulmonary dysfunction, fracture etiology, and comorbidity with ischemic heart disease, and heart failure, hypertension, cerebrovascular disease, and chronic renal failure. Cumulative mortality rate during the first 6 months was 19% (55 of 299 patients) and in the first year it was 25% (76 of 299). At logistic regression analysis, mortality was associated with age, male gender, waiting period for surgery and presence of neoplastic disease or pathological fracture. Waiting for surgery was a significant factor for mortality at 6, 12 and 24 months: patients surgically treated in the first 24 hours had lower mortality than those who waited longer. The risk of mortality in the first 6 months doubled for an age increase of 12 years, while mortality within 2 years doubled for an age increase of 9 years. Although the motality rate after surgery for femoral neck fracture was high in the first year (25%), it dropped off in successive years to levels observed in a healthy population. Thus, we agree with the literature that femoral fracture is a risk factor for survival only in the first year after trauma, above all in the elderly.     

肥大肝叶内胆管结石的处理

目的探讨在肝肥大-萎缩征中肥大肝叶内胆管结石的处理方法。方法回顾性分析我科1990年6月～2004年12月收治的103例肥大肝叶内胆管结石病人的临床资料，总结其手术治疗的原则和方法。结果全体病例均经手术治愈，术后残石率17．5％，效果优良率83．7％。结论肥大肝叶内的胆管结石，手术难度大，应根据病情选择手术方式，既要遵循肝胆管结石的治疗原则，又要保护赖以生存的肥大肝叶（段）。

电视胸腔镜心血管外科手术150例

目的 总结、分析150例电视胸腔镜心血管外科手术的临床结果。方法 应用电视胸腔镜手术技术对动脉导管未闭、房间隔缺损、室间隔缺损、三尖辨关闭不全、冠状动脉-肺动脉瘘、心包积液、原发性长Q-T综合征、雷诺病，心包囊肿等进行治疗。结果 动脉导管未闭均成功在胸腔镜下钳闭；房缺、室缺在胸腔镜体外循环下进行补片修补，冠状动脉瘘胸腔镜下修补；心包积液进行心包活检与开窗引流；长Q-T综合征进行胸腔镜下左T2、T3胸交感神经节切除，均无严重并发症，术后患者恢复良好。结论 电视胸腔镜心血管外科手术可取得满意的临床治疗结果。     

肺鳞状细胞癌81例临床分析

目的 分析81例肺鳞状细胞癌（鳞癌）临床特征，提高早期诊治率。方法 回顾性分析81例肺鳞癌诊断、手术、治疗及随访资料。结果 患者平均年龄62岁，男：女为2．2：1，有吸烟史76例（93．8％），平均26年，全组均有呼吸道症状，合并全身症状14．8％（12例）。确诊时间2～7个月。手术切除病肺63例（77．8％），术后放、化疗。未能切除18例中10例放、化疗。随访中位数5年以上。80例得到随访，1、3、5年生存率为90％（72例）、65％（52例）、47．5％（38例）。结论 肺鳞癌以老年男性多见，易误诊，手术切除率低，早期手术5年生存率高。     

护理学基础课程技术操作教学改革与实践

目的培养高素质实用型护理人才，塑造护生良好形象，使之更加适应现代护理工作需要。方法教师在护理学基础课程技术操作教学过程中，注意通过课前引导学生预习操作内容、精心设计教案、规范操作流程、善于灵活运用示教和多媒体、演练情景剧、开放实验室、强化训练、开展技能考核与比赛等方式培养学生动手操作能力。结果2001年以来，已先后有3届学生进入临床实习。通过问卷调查，学生、带教教师、病人满意度分别达到98．5％、98．2％、97．0％。
