N2 - Objective: To analyze long-Term outcomes following inpatient treatment of infected wounds with antimicrobial or normal saline instillation during negative pressure wound therapy (NPWT). Approach: This was a single-center retrospective study analyzing the course of patients receiving 0.9% normal saline or 0.1% polyhexanide plus 0.1% betaine as instillation for wounds requiring surgery. Measured outcomes included rates of dehiscence, new wounds, re-operations, amputations, and mortality over 5 years. The article adheres to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Results: Forty-Two patients received normal saline instillation and 41 the antiseptic solution. Rates of dehiscence, wound recurrence, and re-operations in the saline and antiseptic cohorts were 6.3% and 5.6%, 9.4% and 5.6%, and 14.3% and 9.8%, respectively (p > 0.05). In patients requiring further surgery, time to wound closure averaged 104 and 130 days in the saline and antiseptic cohorts, respectively (p = 0.81). Five-year amputation and mortality rates were 14.3% and 22% (p = 0.36) and 24% and 17% (p = 0.45) in the saline and antiseptic cohorts, respectively. Innovation: To compare clinical outcomes associated with two fundamentally different instillation solutions over the full wound care episode and elucidate the potential impact of these results for future applications. Conclusion: This is the first evaluation of nonsurrogate outcomes of different instillations for NPWT in infected wounds. The results indicate that normal saline instillation outcomes are comparable to those of 0.1% polyhexanide plus 0.1% betaine. The clinical success, cost benefit, and accessibility of normal saline can expand the utilization of this therapeutic approach for larger patient populations.
