1040例在院病人抗生素一日使用调查报告

目的了解住院病人抗生素使用情况。方法采用横断面调查的方法时我院2005年7月27日所有住院病人抗生素使用情况进行调查。结果抗生素日使用率为34．81％（304／1040），治疗用抗生素占39．67％（144／363），预防用占16．25％（59／363），治疗＋预防占44．08％（160／363），抗生素单用和二联占95．04％（344／363），三联及以上者4．96％（18／363），抗生素日使用种类47种，病原体送检率7．57％（23／304）。结论我院抗生素日使用率不高，抗生素联合使用总体较好，但仍有病原送检率低、抗生素使用品种多、起点高、部分囤术期抗生素预防用药的时机不合理等现象，建议加强宣传教育力度，提高监测速度和指导医师合理用药。     

CT在外伤性胃肠道穿孔急诊中的价值

目的:探讨急诊外伤性胃肠穿孔的CT征象及诊断价值。方法:收集18例经手术证实的外伤性胃肠道穿孔的临床资料及CT征象,分析与总结胃肠道破裂穿孔CT扫描的各种有价值的表现。结果:18例外伤急诊患者中,胃、十二指肠、空回肠与结肠穿孔各1,2,12,3例,其中空回肠为多处破裂,CT主要征象为腹腔散在积液征、游离气腹征、肠系膜与肠壁增厚模糊征、造影剂外溢征。结论:CT扫描在外伤性胃肠道穿孔急诊患者的检查中有定性诊断价值,综合分析各种征象,会明显提高CT的诊断正确率。     

在校护生注射操作损伤及危险因素调查

目的 了解在校护生注射操作损伤发生情况,并探讨危险因素,为提高护生职业防护教育提供参考.方法 采用自行设计的调查表对220名在校护生进行调查.结果 有59名(28.1%)护生注射操作时发生过损伤,其主要危险因素为职业防护意识淡薄、单位时间实验内容过多、天气寒冷操作不便等11个因素.结论 护生注射操作损伤发生率较高;增强防护知识教育、科学合理安排实验室、加强实验室建设等措施,对减少护生注射操作损伤、提高防护意识有现实意义.     

螺旋CT三维重建成像在先天性高肩胛症手术方式选择中的作用

[目的]探讨螺旋CT三维重建技术在先天性高肩胛症分度和手术方式选择中的作用。[方法]22例先天性高肩胛症术前应用螺旋CT对病变部位进行扫描并三维重建，测量以肩胛骨肩胛冈内侧缘为参照点，两侧肩胛骨高度差。根据测量结果依据Cavendish分度将其分类，并根据三维重建成像选择不同的矫形手术术式。[结果]本组22例病人，随访2—4年，外观及功能均有不同程度的改善，未出现神经、血管和椎体等的损伤。[结论]根据螺旋CT扫描和三维重建检查结果，术前即可直观的明确先天性高肩胛症的病变程度，相互关系，伴发畸形，患侧肩胛骨与正常对侧肩胛骨的外观差异等，便于手术操作方案的制定，避免了手术操作的盲目性，减少医源性并发症的发生。     

腹腔镜肝切除术患者的护理

笔者报道腹腔镜肝切除术患者的护理。术前进行心理护理和呼吸训练；术后注意早期活动，加强腹腔镜CO2气腹后的观察、护理，做好皮下气肿、胆漏、出血、高碳酸血症和下肢静脉血栓等术后并发症的观察及护理。认为周到细致的护理是手术成功的重要保证。     

外科危重病人输血适应证选择及合理应用

输血在医疗活动中是很普遍的,美国北卡大学医学实验室的Hay等[1]在对北卡大学附属医院2004年死亡的病人进行回顾性调查分析后发现,有67.9%的病人输过血。大量的输血也造成了血源的紧张,目前我国无偿献血所能提供的血量只相当于临床需要量的60%,而输血的并发症也一直困扰着我们,     

Addressing quality of life issues in adolescents: social skills interventions.

OBJECTIVE: The purpose of this study was to determine whether social skills training can improve the social interaction skills of adolescents with craniofacial conditions (CFCs) in a natural environment (school lunchroom). DESIGN: This study used a pre-post between-group comparison design. Differences between treatment and control subjects were analyzed via a repeated measures analysis of variance. SETTING: The observations were conducted in the respective school lunch-rooms of the adolescents. Social skills groups were conducted in an outpatient clinic setting. MAIN OUTCOME MEASURES: Structured data based on 45 minutes of observation was coded for type, frequency, and duration of social contact. Specific measures included subject initiations and responses, peer initiations and responses, conversation events, total positive communication, and frequency of nondirected comments. RESULTS: Both target and peer-controlled total communication improved across time with adolescents receiving social skills intervention showing significantly more improvement than those adolescents not receiving direct social skills interventions. Adolescents receiving treatment participated in significantly more target initiated conversations lasting at least three interchanges and showed a trend toward a greater frequency of target initiations and positive responses to peer initiations. Peers were more likely to respond to treatment subject initiations after intervention. Fewer treatment subjects used nondirected communication, whereas control subjects continued to use nondirected communication at a slightly increased frequency. CONCLUSIONS: This study provides preliminary evidence that social skills training can increase the frequency of positive social interactions with peers for adolescents with CFCs.     

Use of a violence risk assessment tool in an acute care hospital: effectiveness in identifying violent patients.

This study examined the use and effectiveness of the Alert assessment form. The form is part of the Alert system, used by one large acute care hospital to identify patients with a propensity for violence. All reported incidents of patient violence from August 1, 2003, through December 31, 2004, were included in patient charts. One hundred seventeen violent patient charts were reviewed and compared with 161 non-violent patient charts, randomly chosen from the same time period. Overall use of the Alert assessment form for violent and non-violent patients was 75.7% and 35.4%, respectively. The assessment form was found to have moderate sensitivity (71%) and high specificity (94%). It is reasonably effective in identifying potentially violent or aggressive patients when it is used according to protocol. Efforts to improve the tool are warranted, as is evaluation of its benefit in settings with low prevalence of violence. Also, greater effort must be taken to prevent violence once an aggressive patient has been identified.     

海绵窦上段动眼神经的应用解剖研究

目的：探讨海绵窦上段动眼神经的应用解剖并讨论其临床意义。方法：经血管灌注后观测10例尸颅的海绵窦上段动眼神经及其毗邻与血供。结果：海绵窦上段动眼神经与海绵窦上段背侧紧邻海马钩回，内侧与视交叉、后交通动脉毗邻，外上与脉络膜前动脉相邻，腹侧紧贴鞍背突。海绵窦上段动眼神经80％未见神经外营养血管，可见20％后交通动脉发出1～2根分支进入神经。结论：海绵窦上段动眼神经毗邻结构复杂，滋养血管细小；在海绵窦上缘手术时，应特别注意辨认和保护动眼神经。
