Abstract

Background: Optimal antibiotic prophylaxis duration in head and neck clean-contaminated free-flap cases is unknown.

Methods: A systematic review/meta-analysis was conducted using PubMed/MEDLINE, Cochrane Library, Web-of-Science, and Scopus databases.

Results: Of the 3755 searched articles, 5 articles were included for a total of 861 patients. The recipient surgical site infection risk was significantly higher in patients receiving prophylactic antibiotics for ≤24 hours compared to >24 hours (relative risk [RR] 1.56; 95% confidence interval [CI] 1.13-2.14). In the post hoc multivariate analysis based on available individual-level data on 697 patients from 3 studies, the risk of surgical site infection for ≤24 hours versus >24 hours was not significant after adjusting for antibiotic type (RR 1.09; 95% CI 0.78-1.55). When compared to ampicillin-sulbactam, patients who received clindamycin prophylaxis had an increased likelihood of recipient surgical site infection (RR 2.85; 95% CI 1.95-4.17).

Conclusion: Less than or equal to 24 hours of antibiotic prophylaxis in head and neck clean-contaminated free-flap is likely sufficient but a strong conclusion remains elusive. Clindamycin prophylaxis increases the risk of recipient surgical site infection. Further prospective trials are necessary to clarify.

How strong is the evidence?

Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 861 participants or records.
