Comparison of continuous with single-injection regional analgesia on patient experience after ambulatory orthopaedic surgery: a randomised multicentre trial

Background: The optimal approach to improving patient experience and analgesia after ambulatory orthopaedic surgery remains unclear.Methods: This multicentre, randomised clinical trial compared single-injection nerve block analgesia with home delivery of continuous nerve block analgesia by remote-controlled electronic pump. The primary outcome was patient-reported satisfaction (Evaluation du Vecu de l'Anesthesie Generale [EVAN-G]; 0-100) assessed on postoperative Day 2. Secondary outcomes focused on pain, opioid consumption, quality of rehabilitation, activity tracking using a wearable electronic device, and 90-day quality of life.Results: We randomly assigned 294 patients to continuous pump delivery or single injection. For subjects with normal level of pain catastrophising (Pain Catastrophizing Scale
