Operating room mixing of irrigation solutions “OR-MISS” survey: A look at “homebrew” OR practices in the United States

Serious concerns were identified with OR‑mixed irrigation solutions, including unknown/unintended concentrations, inadequate training and competency evaluations, using non-sterile ingredients, and nonsterile practices. Findings revealed noncompliance with recommended standards and a lack of standardization. Using a clinical practice guideline‑aligned ready‑to‑use irrigation solution instead of OR‑mixed ones may enhance compliance and potentially reduce wound contamination from the irrigation solutions.
