Background: Preoperative skin antisepsis is a cornerstone of surgical site infection (SSI) prevention, evolving from 19th-century empirical observations to modern evidence-based protocols. While the primary goal remains the reduction of microbial load on the skin before incision, the choice of agents and application techniques continues to be a subject of clinical debate.
Historical Evolution: The field originated with Ignaz Semmelweis (1847) and Joseph Lister (1867), who introduced chlorinated lime and carbolic acid, respectively. The mid-20th century saw the introduction of more refined agents, including chlorhexidine gluconate (CHG) and povidone-iodine (PVP-I), shifting the focus from crude disinfection to sophisticated microbial suppression.
Evidence and Guidelines: Landmark trials, notably Darouiche et al. (2010), established the superiority of alcohol-based CHG over aqueous PVP-I, leading to its endorsement as a first-line agent by the WHO, CDC, and NICE. However, recent data from Albanese et al. (2020) suggest that alcohol-based PVP-I is noninferior to alcohol-based CHG when applied with rigorous technique, highlighting the critical role of the alcohol component and standardized application.
Current Best Practices: Modern protocols emphasize a "bundle" approach:
-
Agent Selection: Preference for alcohol-based solutions (CHG or PVP-I).
-
Technique: No-razor hair removal (clipping only) and a "paint-and-dry" method requiring at least 2–3 minutes of wet contact time.
-
Special Populations: Caution is required in neonatal and mucosal applications where alcohol-based solutions may cause chemical burns or toxicity.
Conclusion: While alcohol-based CHG remains the global standard, the efficacy of skin preparation depends heavily on meticulous application and drying times. Future research must address evidence gaps in pediatric populations, the implications of emerging CHG resistance, and the potential of novel antiseptic agents to further reduce the burden of SSIs.
