Anaesthesia
-
General anaesthesia and regional anaesthesia are used for hip and knee arthroplasty but their impact on long-term outcomes remains unclear. This study aimed to compare one-year clinical outcomes and healthcare utilisation in patients receiving general or regional anaesthesia for hip or knee arthroplasty. ⋯ Although general anaesthesia and regional anaesthesia showed comparable one-year mortality, general anaesthesia was associated with lower risks of major depression and care provider dependency but higher readmission rates than regional anaesthesia. These findings suggest that the choice of anaesthesia may have important implications for long-term outcomes beyond mortality.
