Background: Intraoperative anesthetic typically consists of either general anesthesia (GA) or isolated regional anesthesia (RA).
Methods: A retrospective propensity-matched cohort analysis on patients undergoing TSA was performed to determine differences between GA and RA in regard to patient population, complications, LOS and hospital readmission.
Results: 4158 patients underwent TSA with GA or isolated RA. Propensity-matching resulted in 912 patients in each cohort. RA had lower overall in-hospital complications and greater homebound discharge disposition with lower 90-day readmission rates than GA.
Conclusion: After TSA, isolated RA was associated with lower in-hospital complications, readmission rates and odds of hospital readmission than GA.
