Abstract

Five protocols for surgical handwashing (scrubbing) were evaluated for their efficiency of removal of micro-organisms and their drying effect on the skin. The scrubbing protocols tested were: (1) an initial scrub of 5 min and consecutive scrubs of 3.5 min with chlorhexidine gluconate 4% (CHG-5); (2) an initial scrub of 3 min and consecutive scrubs of 2.5 min with chlorhexidine gluconate 4% (CHG-3); (3) an initial scrub of 3 min and consecutive scrubs of 2.5 min with povidone iodine 5% and triclosan 1% (PI-3); (4) an initial scrub of 2 min with chlorhexidine gluconate 4% followed by a 30 s application of isopropanol 70% and chlorhexidine gluconate 0.5%, and a 30 s application of isopropanol 70% and chlorhexidine gluconate 0.5% for consecutive scrubs (IPA); and (5) an initial scrub of 2 min with chlorhexidine gluconate 4% followed by a 30 s application of ethanol 70% and chlorhexidine gluconate 0.5%, and a 30 s application of ethanol 70% and chlorhexidine gluconate 0.5% for consecutive scrubs (EA). A convenience sample of 23 operating theatre nurses completed each scrub protocol for one week in a randomized order. A week of normal work activities intervened between each protocol. Subjects were assessed before commencing and after completing the week of each protocol to determine changes in the microbial counts and skin condition of the hands. Specimens for microbial analysis were collected before, immediately after and 2 h after an initial scrub, and 2 h after a consecutive scrub. The CHG-5, CHG-3 and PI-3 protocols, which used detergent-based antiseptics only, were compared with protocols incorporating an alcohol-based antiseptic (IPA and EA). The protocols incorporating alcohol-based antiseptics and the CHG-5 protocol were generally associated with the lowest post-scrub numbers of colony forming units (cfu). No difference between the CHG-5 protocol and the alcohol-based antiseptics was found at the beginning of the test week, but after exclusive use of the respective protocols for a week, the alcohol-based antiseptics were associated with significantly lower cfu numbers in two out of the three post-scrub samples (P = 0.003, P = 0.035). Although virtually no statistically significant differences in skin condition were found, many subjects reported the alcohol-based antiseptic protocols to be less drying on the skin. The findings of this study support the proposition that a scrub protocol using alcohol-based antiseptics is as effective and no more damaging to skin than more time-consuming, conventional methods using detergent-based antiseptics.

摘要

对五种外科洗手(刷洗)规程的微生物去除效率及其对皮肤的干燥效果进行了评估。所测试的刷洗规程如下:(1)先用4%葡萄糖酸氯己定(CHG - 5)初始刷洗5分钟,随后连续刷洗3.5分钟;(2)先用4%葡萄糖酸氯己定(CHG - 3)初始刷洗3分钟,随后连续刷洗2.5分钟;(3)先用5%聚维酮碘和1%三氯生(PI - 3)初始刷洗3分钟,随后连续刷洗2.5分钟;(4)先用4%葡萄糖酸氯己定初始刷洗2分钟,接着用70%异丙醇和0.5%葡萄糖酸氯己定涂抹30秒,随后连续刷洗时同样用70%异丙醇和0.5%葡萄糖酸氯己定涂抹30秒(IPA);(5)先用4%葡萄糖酸氯己定初始刷洗2分钟,接着用70%乙醇和0.5%葡萄糖酸氯己定涂抹30秒,随后连续刷洗时同样用70%乙醇和0.5%葡萄糖酸氯己定涂抹30秒(EA)。选取23名手术室护士作为便利样本,按照随机顺序对每个刷洗规程进行为期一周的操作。每个规程之间穿插一周的正常工作活动。在开始每个规程的一周前和结束后对受试者进行评估,以确定手部微生物计数和皮肤状况的变化。在初始刷洗前、刷洗后立即、刷洗后2小时以及连续刷洗后2小时采集微生物分析样本。将仅使用基于洗涤剂的防腐剂的CHG - 5、CHG - 3和PI - 3规程与包含基于酒精的防腐剂的规程(IPA和EA)进行比较。包含基于酒精的防腐剂的规程和CHG - 5规程通常与刷洗后最低的菌落形成单位(cfu)数量相关。在测试周开始时,未发现CHG - 5规程与基于酒精的防腐剂之间存在差异,但在各自规程独家使用一周后,在三个刷洗后样本中的两个样本中,基于酒精的防腐剂的cfu数量显著更低(P = 0.003,P = 0.035)。尽管在皮肤状况方面几乎未发现统计学上的显著差异,但许多受试者报告称基于酒精的防腐剂规程对皮肤的干燥作用较小。本研究结果支持以下观点:使用基于酒精的防腐剂的刷洗规程与使用基于洗涤剂的防腐剂的更耗时的传统方法一样有效,且对皮肤的损害更小。
