创伤患者伤口感染的危险因素分析

STUDY OF DANGEROUS FACTORS ABOUT WOUND INFECTION ON TRAUMA PATIENTS

目的 :了解创伤患者伤口感染发生的危险因素。方法 :对我院 1999年～ 2 0 0 1年间 5 2 0例外伤患者进行回顾性调查 ,并对伤口分泌物进行细菌学检查及耐药性分析。结果 :5 2 0例中感染率 14 .0 3% ,感染的病原菌以革兰阳性杆菌为主 (72 .6 % ) ,其次是革兰阳性球菌 (17.8% )和念珠菌 (9.6 % )。在革兰阴性杆菌中 ,大肠埃希菌占主导 (34% ) ,革兰阴性球菌中 ,主要是凝固酶阴性的葡萄球菌 (76 .9% )。这些细菌对抗生素均存在不同的耐药性 ,并有多重耐药的趋势 ; 类伤口感染率 5 6 .9%明显高于 类伤口的感染率7.7% (P<0 .0 5 )。结论 :创伤患者易发生伤口感染 ,特别是重伤及伤口状况差的患者 ,有高的易感性。针对创伤患者应采取相应措施 ,降低感染发生率。

Objective:To study dangerous facters about wound infection on trauma patients.Methods:The trama patients were analysis with 520 cases during 1999～2001.Results:The positive rate of wound infection was 14.3%.The main pathogens was Gram-negative bacteria(72.6),such as Escherichia coli?Pseudomonas aeruginosa et al .Then Gram-negative bacteria(17.8%)and fungi(9.6%).Among Gram-negative bacteria,Coagulase-negative Staphyloccus was main pathogens(72.6%).All the isolated bacteria hsd high drug-resistance rate for common antibiotics.Ⅲ type wound infection rate 56.9% was higher than Itype wound infection rate( P <0.05).Conclusions: The trauma patiens were susceptiple population in infectoon patients.Precaution measurements were introduced to lower the infection rate of trama patients.
