ABSTRACT
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 <30; n=211), median global EVAN-G was higher with the electronic pump compared with the single injection (78 [69-86] vs 72 [63-84]; P=0.03), as were pain satisfaction scores (P=0.01). For the maximum pain levels, the numerical rating scale score was 2.0 (1.0-5.0) in the electronic-pump group vs 5.0 (3.0-7.0) in the single-injection group on the first 2 days after surgery (P<0.0001). Total opioid consumption in morphine equivalent was higher with single injection (mean [standard deviation]) 70.5 [73.8] vs 31.9 [54.2] mg; P<0.01). The groups did not differ in early rehabilitation on Day 1 or quality of life on Day 45. Electronic activity tracking indicated higher activity in the electronic-pump group (P<0.01).CONCLUSIONS:
Self-reported patient satisfaction at home was better with continuous nerve block analgesia via electronic pump vs single injection, without impairing early rehabilitation. Single-injection analgesia was associated with higher pain levels and opioid consumption and lower satisfaction. Patient catastrophising negatively affected the experience of pain.
