Secondary
| Measure | Time frame |
|---|---|
| Blood pressure (BP), heart rate (HR), and oxygen saturation (SpO?) measured at five time points;Amounts of remimazolam, propofol, remifentanil, and sufentanil administered during surgery;Difference in diaphragmatic mobility measurements during deep breathing (baseline vs. post-block PACU evaluation);Changes in diaphragmatic excursion during quiet breathing at baseline versus post-block assessments (PACU and 24-hour);Partial pressure of oxygen (PaO?) at 30 minutes after extubation;Peripheral oxygen saturation (SpO?) at 30 minutes post-extubation and 24 hours post-block;Analgesia duration (time from block completion to first postoperative pain at surgical site), sensory block (time between block completion and return of normal finger sensation), and motor block (time from block completion to recovery of normal grip strength);Resting and movement-evoked pain scores (NRS, 0–10) assessed in PACU and at 6h, 12h, 24h, 48h, and 72h post-block;24-hour analgesic consumption and postoperative nausea and vomiting (PONV);Quality of Recovery-15 (QoR-15) score on postoperative day 1;Length of hospital stay (LOS) and satisfaction scores;Neurological complications (persistent numbness, tingling, or weakness) in the surgical limb were assessed via telephone follow-up at 1 week postoperatively;Grip strength at 30 minutes post-block completion; | — |
