骨科择期手术术中细菌污染的监测研究

Study on bacteria contamination during orthopedic selective operation

目的 探讨骨科择期手术术中细菌污染情况及预防性抗生素的选择和使用。方法手术结束前于切口内组织及术野皮肤取样进行细菌培养及药敏试验。术后使用青霉素钾和奈特预防性用药３～５ｄ。结果本组术中细菌污染率为 １４． ２９％，术后基本无发热，伤口均甲级愈合。分析术中细菌污染与伤口类型密切相关。结论骨科择期手术术中细菌污染不容忽视，术后采用β－内酰胺类和氨基糖苷类配伍预防感染可行。

OBJECTIVE To study the bacteria contamination during orthopedic selective operations and the usage of preventive antibiotics. METHODS The samples got from skin and wound at the end of the operations were sent to conduct bacteria cultur- ing. Penicillin and netimicin were used as preventive antibiotics for 3-5 days postoperation. RESULTS The bacteria contamina- tion rate during operation was 14. 29%. Seldom wes the fever found, and the wound healed by the first intention. Further study showed that the bacteria contamination was closely related with the wound situation. CONCLUSIONS The bacteria contamina- tion during orthopedic selective operations should be paid attention. And it was proved effective that penicillin and netilmicin were used as preventive antibiotics.
