Objective To explore the technique and clinicaleffects of internal fixation of complicated distal femoral fractures using the supporting steel of AO femoral condyles.Methods From October 2001 to February 2004, 23 cases of complicated distal femoral fractures were treated with open reduction and internal fixation using the supporting steel of AO femoral condyles. Of 23 cases, there were 19 males and 4 females, aged 27-55 years. The locations were the right side in 10 cases and the left side in 13 cases. Fracture caused by traffic accident in 16 and by fall in 7, including 14 closed fracture and 9 open fracture, 21 fresh fracture and 2 old fracture. Accordingto AO classification, 6 cases were classified as type A extra-articular fracture and 17 cases as type C intra-articular fracture. The X-ay films before operation showed comminuted fracture of femoral intercondyles and femoral supracondyles. All cases received scientific and rational rehabilitative treatment postoperatively. Results The postoperative follow-up ranged from 6months to 20 months, 23 cases achieved fracture healing with an average healing period of 10.3 months (from 7 months to 16 months). According to the criteria of Kolmert and Wulff, the results were excellent in 16 cases, good in 4 cases, fair in 2 case andpoor in 1 case. The excellenct and good rate was 86.9%.Conclusion Internal fixation with the supporting steel of AO femoral condyles for treatment of complicated distal femoral fractures has advantages of reasonable design, convenient operation, firm fixation and reliable clinical outcome .
摘要:目的:探讨新生儿铜绿假单胞菌肺炎的临床特点及药敏特点,为合理治疗提供依据。方法:对我院新生儿科2006年8月到2008年7月收治新生儿肺炎痰标本进行培养分离鉴定,选择培养结果为铜绿假单胞菌者做药敏及临床分析。结果:铜绿假单胞菌对碳青霉烯类,如:亚胺培南,美洛培南敏感率达100%,对近几年在新生儿较少用的或不用的氨基糖甙类,环丙沙星敏感率为85%～100%,而对常用的氨苄西林+舒巴坦不敏感,对头孢他啶敏感率gt;70%,临床根据药敏结果选择敏感抗生素治疗,疗效满意。结论:近年新生儿铜绿假单胞菌肺炎有上升趋势,病死率极高,故应根据药敏试验结果选择敏感抗生素,以控制疾病发展,降低病死率。
目的:分析探讨终末期慢性肾衰竭(CRF)并急性左心衰的发病机制及救治措施。方法:对36例各种原因所致的终末期CRF患者并急性左心衰采用药物控制血压,降低外周血管阻力,减轻心脏后负荷及采用血液透析等方法,减轻心脏前负荷,控制心衰。结果:36例患者2286次来院救治并发急性左心衰1144次,抢救成功1138次,成功率99.5%。结论:终末期CRF并急性左心衰据发病机理不同,给予不同处理,关键是尽快控制血压,脱水,降低外周血管阻力和控制血容量,降低心输出量。
