手部创面的细菌分布研究

Bacteriological study and treatment of open hand injury

目的 探讨开放性手外伤创面常见污染细菌的种类及敏感抗生素。方法 2 0 0例开放性手外伤 ,于急诊室、手术室刷洗创面后、清创后、关闭伤口前分四次取材 ,作细菌培养及药敏试验。结果 急诊室、手术室刷洗创面后、清创后及关闭伤口前的细菌检出率分别为 71 5 % (14 3/2 0 0 )、 74 0 % (14 8/ 2 0 0 )、 33 5 % (6 7/ 2 0 0 )及 2 5 5 0 % (5 1/ 2 0 0 )。术后伤口感染率为 3 5 % (7/2 0 0 )。对环丙沙星及头孢噻肟敏感性最高。结论 开放性手外伤创面菌种分布广泛 ,以革兰氏阳性菌为主 。

Objective To study the species and origins of bacteria on open hand injury.Methods 200 patients of open hand surgery randomly selected,bacteria from wound was cultivated individually in the emergency room,after the wound scrubbed,after debridement and before wound closure.Results The percents of cultivated bacteria from the wound in the emergency room,after the wound scrubbed,after debridement and before wound closure were 71 5%(143/200)?74 0%(148/200)?33 5%(67/200)and 25 5%(51/200).The infected rate of wound was 3 5%(7/200).The most sensitive antibiotic were cinrofloxacin and cefetamime.Conclusion The bacterial species of open hand injury were distributed widespreadly,Thorough debridement and keeping operative instruments clean are the main measures to decrease the infection in post operation.
