Wagner JL, Kenney RM, Vazquez JA, Ghanem TA, and Davis SL. Surgical prophylaxis with gram-negative activity for reduction of surgical site infections after microvascular reconstruction for head and neck cancer Head Neck 2016; Oct;38(10):1449-54.
Head & neck
BACKGROUND: The purpose of this study was to determine the incidence of and risk factors for surgical site infections in microvascular reconstruction for patients with head and neck cancer.
METHODS: One hundred seventeen patients with head and neck cancer undergoing microvascular reconstruction received postoperative surgical infection prophylaxis and were followed for 30 days. Surgical infection prophylaxis was categorized by empiric spectrum of activity. Risk factors for surgical site infection development and cumulative incidence of surgical site infections were characterized.
RESULTS: Thirty-seven patients developed surgical site infection (cumulative surgical site infection incidence of 31.6%). Risk factors identified in logistic regression include alcohol use (odds ratio [OR] = 2.704; 95% confidence interval [CI] = 1.029-7.106), increased surgical duration (OR = 1.403; 95% CI = 1.185-1.661), American Society of Anesthesiologists (ASA) class IV (OR = 3.075; 95% CI = 1.000-9.459), and lack of postoperative gram-negative coverage (OR = 15.139; 95% CI = 3.083-74.347).
CONCLUSION: Alcohol use, longer surgical duration, and lack of gram-negative postoperative prophylactic coverage are modifiable risk factors for surgical site infection development. © 2016 Wiley Periodicals, Inc. Head Neck 38: First-1454, 2016.
