Multidisciplinary Expert Consensus Statements and Recommendations for Use of Hypochlorous Acid as a Solution for Negative Pressure Wound Therapy With Instillation

Abstract

Background. HOCl (eg, pHAp) preserved solutions have antimicrobial properties and are considered safe and effective for wound management. NPWTi-d (or NPWTi) is an established adjunctive wound modality for a variety of wound etiologies in various anatomic locations in which an instillate solution dwells on the surface of the wound to assist in wound bed preparation. A variety of solutions have been used, including 0.9% normal saline wound cleansers and antiseptics. pHAp is growing in popularity as the solution of choice for NPWTi-d. Objective. To evaluate consensus statements on the use of NPWTi-d with pHAp. Methods. A 15-member multidisciplinary panel of expert clinicians in the United States, Canada, and France convened in person in April 2023 in Washington, D.C. and/or corresponded later to discuss 10 statements on the use of pHAp with NPWTi-d. The panelists then replied "agree" or "disagree" to each statement and had the option to provide comments. Results. Ten consensus statements are presented, along with the proportion of agreement or disagreement and summary comments. Although agreement with the statements on NPWTi-d with pHAp varied, the statements appear to reflect individual preferences for use rather than concerns about safety or efficacy. Conclusion. The consensus indicates that NPWTi-d with pHAp can have a beneficial effect in wound care.
