Multimodal oral analgesia strategy after ambulatory arthroscopic shoulder surgery: case series using adaptive therapeutic approaches by sequential analysis.

BACKGROUND: 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. METHODS: 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). RESULTS: 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. CONCLUSION: 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.

How traditional and digital analytics interventions can enhance lung-protective ventilation strategies during general anaesthesia: A two-year quality improvement project analysis.

PURPOSE: This quality improvement project evaluated interventions implemented to enhance individual adherence to a lung-protective ventilation strategy and its triad: low tidal volume, PEEP ≥ 5, recruitment manoeuvres. METHODS: For two years, nine anaesthesia workstations were connected to an automated cloud-based analytics software tool, which automatically recorded ventilation parameters as soon as a new patient case was opened. Four quality improvement periods were determined over the first year: baseline, intervention, no intervention, intervention + digital. In the second year, the digital strategy was continued for nine months, followed by a final "overtime" period. Baseline and no intervention periods included no training. The intervention period included both conventional and educational programs. The digital period included pop-up messages, which automatically appeared on the screen of the anaesthesia data management system when patients were intubated. The primary endpoint was provider adherence to the recommended triad. RESULTS: From October 2018 to December 2020, 12,883 procedures were performed. Data were available for 8968 procedures: baseline (n = 2361), intervention (n = 2423), no intervention (n = 1064), intervention + digital (n = 1862), overtime (n = 1258). Age, Predicted Body Weight, ASA score, type of surgery and airway management were similar between periods. At baseline, 75.2% of procedures reported low tidal volume but only 6.9% involved the complete triad. At over time, Triad was 22% (p < 0.001). Over study period, each parameter of the Triad (RM, Vt and Peep) increased (p < 0.001 vs. baseline), driving pressure decreased although EtCO2 and plateau pressure had not changed. CONCLUSION: Training with the help of digital apps improved LPV adherence over time.
