无盖杰雪的消毒效果观察

Experimental study on no-covered Jie Xue's sterilizing effect.

目的验证无盖杰雪消毒效果的可靠性，为临床使用提供客观实验依据。方法①浓度测定（实验组：无盖洁雪12瓶放置60d后检测浓度；对照组：有盖洁雪12瓶放置60d后检测浓度）。②皮肤实验（自身对照，实验组30例：无盖杰雪消毒患者右手背皮肤，消毒区采样细菌培养72h；对照组30例：有盖杰雪消毒患者左手背皮肤，消毒区采样细菌培养72h）。结果①浓度测定；有盖洁雪、无盖杰雪浓度均在标准范围内（醋酸氯已定5．0±5．5g/L、乙醇70％75％），两者比较差异无统计学意义（醋酸氯已定t=-0．196，P=0．847、乙醇t=-0．355，P=0．726）；②皮肤实验：有盖洁雪、无盖杰雪消毒皮肤后均无细菌生长。结论无盖杰雪消毒效果可靠。

Objective To verify the reliability of no-covered Jie Xue＇s sterilizing effects, and to provide the objective evidences for clinical application. Methods （1） Concentration experiment： the concentration was measured in 12 bottles of no-covered Jie Xue after 60 day （the study group） and 12 bottles of covered Jie Xue after 60 days （the control group）. （2） Skin experiment： The dorsal skin from 30 patients were disinfected with no-covered Jie Xue （on the fight side, the study group） and covered Jie Xue （on the left side, the control group）, then sampling and 72-hour bacterial culture were performed. Results （1） Concentration experiment： The concentrations of no-covered Jie Xue and covered Jie Xue were both in standard range （Chlorhexidine Acetate 5.0--5.5 g/L, Ethanol 70%-75%）, with no statistically significant difference （Chlorhexidine Acetate t=-0.196, P=0.847; Ethanol t=-0.355, P=0.726）. （2） Skin experiment： There were no bacteria grown in both groups for skin experiment. Conclusion No-covered Jie Xue＇s sterilizing effects is reliable.
