Key result
Spinal anesthesia for total joint arthroplasty was associated with fewer 30-day complications and nonhome discharges compared to general anesthesia (P<0.05).
Why the study?
The authors sought to compare 30-day mortality, complication rates, and discharge disposition between spinal anesthesia and general anesthesia for total knee and total hip arthroplasty.
Does spinal anesthesia reduce 30-day complications and mortality compared to general anesthesia in patients undergoing total knee and hip arthroplasty?

May support spinal anesthesia preference in total joint arthroplasty; hypothesis-generating and requires randomized confirmation.

Does spinal anesthesia reduce 30-day complications and mortality compared to general anesthesia in patients undergoing total knee and hip arthroplasty?
p-value: p=<0.05
Spinal anesthesia is associated with fewer 30-day complications and a lower likelihood of nonhome discharge compared to general anesthesia for total joint arthroplasty.
Warren et al. (2019) conducted a cohort in Total knee and hip arthroplasty (n=294,043). Spinal anesthesia vs. General anesthesia was evaluated on 30-day mortality, major and minor complication rates, and discharge disposition (p=<0.05). Spinal anesthesia for total joint arthroplasty was associated with fewer 30-day complications and nonhome discharges compared to general anesthesia (P<0.05).
