Abstract Background: Surgical site infections (SSI) contribute to surgical patients' morbidity and costs. Operating room traffic may be a modifiable risk factor for SSI. We investigated the impact of additional operating room personnel on the risk of superficial SSI (sSSI). Patients and Methods: In this matched case-control study, cases included patients in whom sSSI developed in clean surgical incisions after elective, daytime operations. Control subjects were matched by age, gender, and procedure. Operating room personnel were classified as (1) surgical scrubbed, (2) surgical non-scrubbed, or (3) anesthesia. We used conditional logistic regression to test the extent to which additional personnel overall and from each work group were associated with infection. Results: In total, 474 patients and 803 control subjects were identified. Each additional person among total personnel and personnel from each work group was significantly associated with greater odds of infection (all personnel, odds ratio [OR] = 1.082, 95% confidence interval [CI] 1.031–1.134, p = 0.0013; surgical scrubbed OR = 1.132, 95% CI 1.029–1.245, p = 0.0105; surgical non-scrubbed OR = 1.123, 95% CI 1.008–1.251, p = 0.0357; anesthesia OR = 1.153, 95% CI 1.031–1.290, p = 0.0127). After adjusting for operative duration, body mass index, diabetes mellitus, and vascular disease, additional personnel and sSSI were no longer associated overall or for any work groups (total personnel OR = 1.033, 95% CI 0.974–1.095, p = 0.2746; surgical scrubbed OR = 1.060, 95% CI 0.952-1.179, p = 0.2893; surgical non-scrubbed OR = 1.023 95% CI 0.907–1.154, p = 0.7129; anesthesia OR = 1.051, 95% CI 0.926–1.193, p = 0.4442). Conclusion: The presence of additional operating room personnel was not independently associated with increased odds of sSSI. Efforts dedicated to sSSI reduction should focus on other modifiable risk factors.

SummaryBackgroundBardet–Biedl syndrome (BBS) is a rare genetic condition with manifestations that can impact anesthetic and perioperative care. There is a void of literature describing the perioperative anesthetic management in this complex patient population.ObjectivesThe purpose of this retrospective series was to describe the perioperative care of patients diagnosed with BBS at a large academic tertiary referral center with experience in caring for these patients.MethodsAll patients receiving anesthesia during the time between July 10, 1997 and Jan 1, 2015 were identified. Anesthetic and perioperative records were reviewed in detail for demographic, echocardiographic, preoperative, intraoperative, and postoperative data.ResultsWe identified 12 patients with BBS undergoing 40 anesthetics at our institution. The study identified a high risk for difficult airway with need for advanced airway techniques (67% of patient's ≥18 years of age required either awake fiberoptic or video laryngoscopy techniques), cardiac abnormalities, renal impairment, morbid obesity, and intellectual disability as the main syndrome manifestations of interest to the anesthesiologist. No patient had perioperative complications directly related to BBS; however, each underwent thorough perioperative evaluation with emphasis on the systemic comorbidities associated with the syndrome. This report illustrates that patients with BBS can safely undergo anesthesia, but a detailed and often multidisciplinary preoperative evaluation is prudent.
