Objective To evaluate the feasibility of a new approach to internal jugular vein (IJV) catheterization. Methods Sixty patients undergoing cardiac surgery were randomly divided into two groups (n=30). In group Ⅰ, a new method was used. In group Ⅱ, IJV catheterization from a high medial approach. The overall succcess rate of puncture, the success rate of puncture at first attempt, the success rate of cannulation and complication were recorded. Chest X-ray was taken for confirmation of the position of catheter in subclavian vein. Results The overall success rate of puncture was 100% and the success rate of puncture at first attempt was 93.33% in group Ⅰ, which is significantly higher than those in group Ⅱ(P<0.05). No complication occurred in group Ⅰ including arterial puncture, pneumothorax, hematothorax and difficult catheter placement. In group II there were 3 arterial punctures. Con-clusion This new method is a reliable and safe technique in patienst as compared with the high medial approach. 相似文献

目的积极应对我国西北边境口岸日益严重的恐怖威胁,加强乌鲁木齐机场口岸应对化学恐怖事件的处置能力。方法按照《有害气体泄漏事件应急处置演练脚本》,启动《核生化突发公共卫生事件应急处置预案》,通过合理安排,多部门协作,展开对涉恐化学泄漏事件的应急处置演练。结果演练过程基本按照《演练脚本》的预定规程进行,通过演练提高了口岸检验检疫部门相关人员的专业水平和应对能力。结论现有《核生化突发公共卫生事件应急处置预案》的实用性得到了检验,检验检疫人员以往的培训成果得以发挥,同时在演练现场也暴露出若干问题,如:部分仪器过于老旧,预案体系完整性不足等,需要进一步加强完善。 相似文献

上尿路结石围手术期尿细菌检测的临床意义 总被引:1,自引:0,他引:1
目的 分析上尿路结石患者围手术期尿细菌谱及其药敏结果,指导抗生素治疗,减少术后发热和感染并发症.方法 2009年1月至2010年9月,148例上尿路结石患者行经皮肾镜取石术,对患者术前中段尿、术中感染性结石、术后肾造瘘管末端进行细菌培养,选择敏感药物行抗感染治疗,并对细菌谱、术后发热及感染并发症进行总结分析.结果 148例患者中段尿细菌培养阳性38例(25.7%),其中大肠埃希菌17例(44.7%)、表皮葡萄球菌4例、奇异变形杆菌3例、肺炎克雷伯杆菌3例、铜绿假单胞菌2例、屎肠球菌2例、溶血葡萄球菌2例、鲁氏不动杆菌1例、弗氏柠檬杆菌1例、酵母样菌1例、摩氏摩根菌1例、腐生葡萄球菌1例;感染性结石10例,细菌培养阳性8例,其中大肠埃希菌和奇异变形杆菌各3例,酵母样菌和铜绿假单胞菌各1例;肾造瘘管细菌培养阳性25例(16.9%),其中表皮葡萄球菌5例、溶血葡萄球菌5例、铜绿假单胞菌5例、屎肠球菌3例、科氏葡萄球菌2例、沃氏葡萄球菌2例、蜡样芽孢杆菌1例、产气肠杆菌1例、粪肠球杆菌1例.3种标本共培养344例次,阳性71例次,总阳性率20.6%.培养阳性者常用敏感药物包括亚胺培南、头孢吡肟、万古霉素、呋喃妥因等.术后发热患者41例(27.7%),包括术前中段尿培养阳性10例和肾造瘘管培养阳性患者9例;术后出现感染性休克1例.结论上尿路结石术前尿细菌以革兰阴性杆菌为主,术后末期革兰染色阳性球菌常见;术前中段尿培养能指导抗生素应用,有效控制围手术期尿路感染,减少并发症.Abstract: Objective To analyze the bacterial distribution and resistance in upper urinary tract stone patients, then choose suitable antibiotics and reduce infectious complications accordingly.Methods Middle flow urine, infectious stone and the end of kidney drainage tube were taken for culture in 148 patients who underwent percutaneous nephrolithotomy between January 2009 to September 2010. Antibiotics were used according to the culture results and the complications secondary to infection were analyzed. Results Urinary pathogens presented in 38 (25.7%) patients before operation.There were 112 strains of bacteria. The predominant strains included: Escherichia coli (17 cases,11.5%), Staphylococcus epidermidis (4 cases) and Proteus mirabillis (4 cases). Escherichia coli and Proteus mirabillis were common in stone culture. Staphylococcus epidermidis (5 cases),Pseudomonas aeruginosa (5 cases) and Staphylococcus haemolytcus (5 cases) were found in renal drainage tube culture which were positive in 25 patients. Imipenem, cefepime, vacomycin, nitrofurinton were sensitive and commonly used antibiotics. Forty-one patients (27.7 %) had fever postoperatively, including 10 positive for middle urine culture and 9 positive for drainage tube culture. One infective shock was diagnosed postoperatively. Conclusions Gram-negative bacilli are predominant in the upper urinary tract stone patients preoperatively. Gram-positive ones are common postoperatively.Suitable antibiotics, based on middle flow urine culture, could reduce urinary infective complications. 相似文献
