First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watches 2000 people having hip or knee replacement surgery to see how long spinal anaesthesia lasts. The goal is to learn how the amount of anaesthetic affects timing, helping doctors decide if patients can safely go home the same day. No new treatments are tested—just careful observation.
