For patients undergoing total hip arthroplasty, some evidence suggests that perioperative outcomes are more favorable with regional anesthesia than with general anesthesia. To shed additional light on this issue, U.S. researchers accessed a large surgical database that included detailed information on 13,000 total hip arthroplasties. Forty percent of patients received regional anesthesia (mostly spinal), and 60% received general anesthesia; the two groups were compared using propensity matching and multivariable analyses.
Regional anesthesia patients, compared with general anesthesia patients, were significantly less likely to have surgical site infections (3 fewer per 1000 patients), cardiovascular complications (5 fewer per 1000 patients),…
