提高医院感染填报准确性和及时性,降低漏报率,是全面了解情况,做好医院感染监控,制定控制策略的重要前提.但是目前我院多数科室存在医院感染漏报率差距过大、数据不准确等现象,为了提高医院感染漏报率的可信度,分析医院感染漏报原因是必不可少的方法之一.

目前在临床化学室内的质量控制工作中仍有流于形式、工作不扎实的现象存在,为了切实发挥室内质控的作用,我们在质控工作中侧重于质控品均值和标准差的确定,在对质控结果的分析中,侧重于查找系统误差,从而保证了室内质控工作的质量.

学龄期儿童活动性较强,外伤后容易造成牙齿松动移位,其中尤以切牙外伤多见[1].临床上如果采用常规的结扎丝等固定方法,常存在患者不配合,固位不牢等缺点.我科根据替牙期混合牙列的特点,自2003年以来,采用方丝弓托槽进行松牙固定,取得了良好效果.现将治疗情况及体会报道如下.

①目的探讨院内尿路感染病原菌的现状及体外耐药性,为临床医师提供诊断和治疗依据。②方法住院患者尿液培养中分离出192株病原菌进行鉴定和体外耐药性试验。③结果泌尿系感染菌株以大肠埃希菌为主,占34.3%;其次为表皮葡萄球菌、肠球菌、产气肠杆菌、铜绿假单胞菌、真菌。体外耐药试验表明,肠杆菌科对抗生素耐药率均较严重;革兰阳性球菌耐药率也相当严重。④结论泌尿系感染最主要病原菌为大肠埃希菌。医师合理使用抗生素,重视病原菌的培养和药敏,是预防院内泌尿系感染的重要措施。

Objective To explore the experience of long-term outcomes of orthotopic heart transplantation. Methods From Aug. 1995 to Dec. 2004, 40 patients with end-stage dilatation cardiomyopathy, 36 males and 4 females, aged 13～60 years underwent orthotopic heart transplantation (OHT) , 39 standard styles and 1 total style. Results 40 cases were all successful treated. The survival time is from 8 to 112 months with heart function of 0-I degree. All cases are in good quality of live and enjoy normal entertainments and work. Pulmonary infection and cardiac arrhythmia are the most common complications but they did not degrade the result after proper treatments. Conclusion Heart transplantation is an effective treatment for patients with end-stage heart diseases. Appropriate selections of recipients with low pulmonary vascular resistance, satisfactory myocardial preservation are the key points to success. The precautions and prompt treatments to the postoperative complications are guarantee for the ultimate results of heart transplantations.

Objective To explore the related causes and management of the death cases (following) orthotopic heart transplantation (OHT). Methods The data of the death cases (14 cases) were studied retrospectively.Results Fourteen cases died among the total 54 cases of OHT from Aug. 1995 to Dec. 2004 in our hospital. Eight cases died within 1 month and 1 case subject to combined heart-kidney transplantation died on the 38th day, and the other 5 cases died during the period from 17 weeks to 4 years. The death cases died of acute right ventricular failure (4 cases), lung infection (5 cases, including 3 cases associated with fungus infection), acute rejection (4 cases), acute renal failure (4 cases), arrhythmia (4 cases), adult respiratory distress syndrome (2 cases) and diabetes (2 (cases)). The death of 8 cases was related with several causes.Conclusion Various causes should be (responsible) for the results. In order to decrease the mortality rate, the recipients should be selected with low pulmonary vascular resistance and less preoperative complications. It is very important to discover and manage complications in time perioperatively.
