Comparison of Skin Antiseptic Agents and the Role of 0.01% Hypochlorous Acid 2026-08-20 00:00

Abstract

Background: Hypochlorous acid (HA) has both anti-microbial and wound-healing properties with a growing role for utilization in pre-procedural care on the face.

Objectives: The authors sought to compare the antiseptic property of 0.01% HA solution, 5% povidone iodine (PI), 4% chlorhexidine gluconate (CHG), and 70% isopropyl alcohol (IPA) antiseptic on facial skin.

Methods: This was a prospective single-center clinical trial.

Results: A total of 21 participants were recruited. Bacterial growth was seen in CHG (10%), IPA (71%), PI (81%), and HA (95%) of specimens (P < 0.001). CHG had less growth compared with HA (P = <0.001), IPA (P = <0.001), and PI (P = <0.001). No difference in bacterial growth was noted between HA and IPA (P = 0.063) or HA and PI (P = 0.25). Significant differences in mono-microbial and poly-microbial growth were seen between HA and IPA (P = 0.046) and HA and CHG (P = <0.001). Staphylococcus epidermidis grew less frequently in CHG (10%), followed by IPA (29%), PI (71%), and HA (71%). Staphylococcus capitis grew less frequently in CHG (0%), followed by PI (14%), HA (24%), and IPA (29%).

Conclusions: CHG reduced the bacterial growth compared with HA, PI, and IPA. However, HA, PI, and IPA had insignificant differences in bactericidal effects. Our study provides a supporting role of HA to be considered as an antiseptic.

【家庭护理】严防足部皮肤破损！糖尿病患者护脚指南

糖尿病患者大约有1.5%会发生足部溃疡，足部溃疡经久不愈，继发感染，发生坏疽。糖尿病足的截肢率很高，有报道称截肢率可高达85%，给患者造成极大痛苦，而通过积极的预防措施，可以降低40%~80%的截肢发生率。

　　在糖尿病足的预防和综合治疗中，足部护理占有特别突出的地位，通过家庭中实施的足部护理，可有效地防止或延缓糖尿病足的发生发展。足部护理的主要内容包括以下方面：

　　注意局部皮肤变化，观察皮肤的色、温度及感觉。如皮肤干燥无汗、弹性差、毛发脱落、皮温下降、皮色变暗、足背动脉搏动减弱或消失，提示动脉供血不足；如皮肤感觉缺失提示有神经营养障碍。

　　注意足部的保护，鞋袜要合适，最好选用软底布鞋及棉线袜，穿着以舒适不挤脚为宜，以保证足部血液循环的供应。由于糖尿病患者末梢神经感觉障碍，对冷热等物理刺激反应迟钝，因此冬天注意足部保暖，避免冻伤，用热水袋取暖时，热水袋内水温不超过60℃，热水袋外面用毛巾套包裹，不可直接触及皮肤，以防烫伤。

　　注意足部卫生，每晚用40~42℃的温水浸泡双脚15~30分钟，洗后用柔软吸水性强的毛巾擦干。消除过厚角质层防止干裂，可涂上植物油按摩，以保持皮肤柔软。

　　按摩足部以改善微循环。足部按摩每日早、中、晚各一次，每次10分钟，动作轻柔，应从趾尖开始向上按摩，有利于循环流畅。

　　修剪趾甲不应太靠近皮肤以免损伤甲沟皮肤导致感染，应沿着足趾甲平行修剪，不要剪向趾甲边角的深部。有胼胝的患者不要自行处理，应请专业人员帮助处理，避免不适当地应用鸡眼膏或脚癣浸泡液，以免造成足部感染。

　　减轻病变部位的负重。为了减轻病变局部的压迫，患者应注意卧床休息，不可长时间站立，行走时使用拐杖。患肢水肿者，把患肢抬高18~30°以利于静脉回流，减轻水肿。

　　日常多进行腿部运动，每日适当步行，做到定时、定量、量力而行、持之以恒。对较轻的患者可在护士的指导下，手扶椅子做单腿站立或甩腿运动，不能行走的患者在床上取坐姿位做提足运动，每日1~2次，每次至少20下。

　　糖尿病患者足部皮肤常易发生水疱，皮肤水疱易诱发感染和坏疽，一旦出现要积极处理。保持水疱清洁，避免受压，微循环改善后可自行吸收；对严重的水疱，可在无菌操作下抽出渗液。医生建议，出现了类似水疱等糖尿病皮肤早期皮肤损害，应当前往医院，在专业医护人员的指导下进行处理。

Objective: Hypochlorous acid (HOCl), a major inorganic bactericidal compound of innate immunity, is effective against a broad range of microorganisms. Owing to its chemical nature, HOCl has never been used as a pharmaceutical drug for treating infection. In this article, we describe the chemical production, stabilization, and biological activity of a pharmaceutically useful formulation of HOCl. Methods: Stabilized HOCl is in the form of a physiologically balanced solution in 0.9% saline at a pH range of 3.5 to 4.0. Chlorine species distribution in solution is a function of pH. In aqueous solution, HOCl is the predominant species at the pH range of 3 to 6. At pH values less than 3.5, the solution exists as a mixture of chlorine in aqueous phase, chlorine gas, trichloride (Cl− 3 ), and HOCl. At pH greater than 5.5, sodium hypochlorite (NaOCl) starts to form and becomes the predominant species in the alkaline pH. To maintain HOCl solution in a stable form, maximize its antimicrobial activities, and minimize undesirable side products, the pH must be maintained at 3.5 to 5. Results: Using this stabilized form of HOCl, the potent antimicrobial activities of HOCl are demonstrated against a wide range of microorganisms. The in vitro cytotoxicity profile in L929 cells and the in vivo safety profile of HOCl in various animal models are described. Conclusion: On the basis of the antimicrobial activity and the lack of animal toxicity, it is predicted that stabilized HOCl has potential pharmaceutical applications in the control of soft tissue infection.
