Résumé
Pain control and quality of recovery (QoR) at home remains a challenge after ambulatory shoulder arthroscopy. This study aims to assess the QoR and pain relief using a sequential implementation strategy for rescue analgesic drugs.
After institutional review board approval, patients (>18 years, American Society of Anesthesiology [ASA] score 1-3 stable) scheduled for ambulatory surgery under general anesthesia with a single-shot interscalene nerve block were enrolled. After discharge, patients received standard information regarding the postoperative recovery and care consisting of a multimodal analgesic regime (acetaminophen and ketoprofen for 5 days). The first 48 postoperative hours allowed us to compare 3 different rescue drug regimes with a control group, in sequential order: tramadol (control group), tramadol + nefopam, immediate-release oxycodone (IR), and extended-release oxycodone (ER). The primary endpoint was the QoR 40 score at 48 hours after surgery. Secondary endpoints were pain relief and adverse events over a 7-day period. An intention-to-treat statistical analysis was performed with sequential analysis (as an interim analysis) every 20 patients. Results were recorded as medians and interquartiles (25-75).
We analyzed 109 patients with similar characteristics among groups. The QoR 40 scores were similar for the tramadol group (168 [161-172]), the tramadol + nefopam group (161 [151-173], P = .09), and the IR group (164 [153-169], P = .17), but higher for the ER group (176 [167-181], P = .03). Concerning adverse events, drugs were interrupted more frequently in the tramadol + nefopam group (36 %). In the ER group, a higher quality of postoperative relief was attained in the domains of pain and sleep.
The present study shows that a combination of IR and ER oxycodone over a short period of time (<48 hours) is associated with a better QoR at home after ambulatory shoulder surgery.
