• Umbilical hernia repair
• General anesthesia
• Monitored anesthesia care
• 30-day complications
• Hospital stay

Monitored anesthesia care with intravenous sedation (MAC/IV), recently proposed as a good choice for hernia repair, has faster recovery and better patient satisfaction than general anesthesia; however the possibility of oversedation and respiratory distress is a widespread concern. There is a paucity of the literature examining umbilical hernia repairs (UHR) and optimal anesthesia choice, despite its importance in determining clinical outcomes.
A retrospective analysis of anesthesia type in UHR was performed in the National Surgical Quality Improvement Program 2005-2013 database. General anesthesia and MAC/IV groups were propensity-score-matched (PSM) to reduce treatment selection bias. Surgical complications, medical complications, and post-operative hospital stays exceeding 1 day were the primary outcomes of interest. Pre-operative characteristics and post-operative outcomes were compared between the two anesthesia groups using univariate and multivariate statistics.
PSM removed all observed differences between the two groups (p > 0.05 for all tracked pre-operative characteristics). MAC/IV cases required fewer post-operative hospital stays exceeding 1 day (3.5 vs 6.3 %, p < 0.001). Univariate analysis showed that overall complication rate did not differ (1.7 vs 1.8 %, p = 0.569), however MAC/IV cases resulted in fewer incidences of septic shock (< 0.1 vs 0.1 %, p = 0.016). After multivariate logistic regression, MAC/IV was revealed to yield significantly lower chances of overall medical complications (OR = 0.654, p = 0.046).
UHR under MAC/IV causes fewer medical complications and reduces post-operative hospital stays compared to general anesthesia. The implications for surgeons and patients are broad, including improved surgical safety, cost-effective care, and patient satisfaction.
