不同类别护手霜对洗必泰类外科手消毒剂消毒效果的影响

目的探讨不同护手霜对洗必泰类外科手消毒剂消毒效果的影响。方法将60名手术室医护人员随机分成A、B、C三组。受试者均按六步洗手法洗手1 min，用无菌擦手纸擦干双手。 A组不使用护手霜，B、C组分别使用3M爱护佳9260护手霜（水包油乳化液）及某品牌凡士林护手霜（油包水乳化液）。分别采集各组洗手后、使用护手霜后30 min及外科手消毒后的手部样本,进行细菌培养及菌落计数。结果洗手后各组间菌落计数比较，差异无统计学意义（P＞0.05）。擦护手霜后30 min，各组间［A组：（3.33±0.64）CFU/cm2；B组：（3.32±0.97）CFU/cm2；C组：（4.05±1.78）CFU/cm2］比较, 菌落计数差异有统计学意义，C组菌落计数显著高于A、B组(P<0.05)；A、B两组差异无统计学意义（P＞0.05）。外科手消毒后，A、B两组受试者均达到外科手消毒要求，差异无统计学意义（P＞0.05）；C组有2人未达到外科手消毒要求，且菌落计数［（1.28±1.45）CFU/cm2］显著高于A组［（0.07±0.10）CFU/cm2］及B组［（0.06±0.12）CFU/cm2］ (P<0.05)。结论使用与乳胶及洗必泰兼容的护手霜（水包油乳化液）可有效保护手部皮肤,同时对外科手消毒无显著影响。

Influence of different hand lotions on the efficacy of chlorhexidine surgical hand disinfectant

ObjectiveTo evaluate the influence of different hand lotions on the efficacy of chlorhexidine surgical hand disinfectant.MethodsSixty health care workers were randomly divided into group A, B, and C. All subjects washed their hands for 1 minute according to six step hand washing technique, and hands were dried with sterile paper towels. Group A didn＇t use hand lotion, group B and C used 3M 9260 hand lotion （water in oil emulsion） and certain brand vaseline hand lotion （oil in water emulsion） respectively. Bacterial cultures of hands in three groups were performed after washing hands, using hand lotions 30 minutes later and disinfecting with surgical hand disinfectant, bacterial colonies were counted.ResultsAfter washing hands, the difference in colony count was not significantly different among three groups （P〉0.05）. Thirty minutes after using hand lotions, colony count in group A, B, and C was （3.33±0.64） CFU/cm2, （3.32±0.97） CFU/cm2, and （4.05±1.78） CFU/cm2 respectively, colony count in group C was significantly higher than group A and B （P〈0.05）; there was no significant difference between group A and B （P〉0.05）. After surgical hand disinfection, both group A and B met requirements for surgical hand disinfection, the difference was not significantly different （P〉0.05）; two subjects in group C didn＇t meet requirements for surgical hand disinfection, and the colony count （1.28 ± 1.45]CFU/cm2） was significantly higher than group A （0.07 ± 0.10]CFU/cm2） and B （0.06 ± 0.12]CFU/cm2） （P〈0.05）.ConclusionHand lotion containing latex and chlorhexidine can protect hand skin and doesn＇t reduce efficacy of surgical hand disinfection.
