脑外科手术中无菌生理盐水两种给水方式的效果探讨

Effect of Modes of Feeding Sterilized Saline in Cerebral Surgery

目的探讨脑外科手术中两种方式应用生理盐水的效果。方法将64例颅脑外科择期无菌手术患者,随机分为开放式给水和密闭式给水各32例。在不同时间点,两种无菌生理盐水同时取样,并进行细菌培养监测。结果密闭组手术中使用的无菌生理盐水未检出细菌。开放组随手术时间和无菌生理盐水开放的时间延长,冲洗水中细菌的检查数量逐渐增加,两组比较有显著差异(P<0．05)。结论使用密闭式无菌生理盐水可以有效控制细菌污染,降低手术感染率,减轻患者痛苦和负担。

Objective To monitor and compare the pollution of open and closed sterilizing saline used in cerebral surgery so as to analyze the reasons. Methods 64 patients were randomly divided into open water fed group （ n = 32） and closed one （ n = 32）, Samples of saline water were taken from both groups at different point of time for bacterial culture. Results No bacteria were found in the closed group. More bacteria grew gradually with consuming of the operation time and exposure of sterilizing saline water, Significant difference was shown （P〈0.05）, Conclusion Use of closed sterilized saline water can control pollution and reduce infectious rate and alleviate patient＇s pain and sufferings as well.
