Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The difference in pain scores before and after the loss of the nerve block analgesic effect.;The intensity and incidence of rebound pain at the surgical site.; | — |
Secondary
| Measure | Time frame |
|---|---|
| Duration of nerve block;NRS scores for resting pain at 8h, 12h, and 24h post-surgery, and the worst pain score at 48h post-surgery;Time to first report of pain and time to first request for analgesia (in hours);Number of requests for analgesia;Total amount of opioid drugs, tropisetron, and dezocine used within 24 hours post-surgery;Patient satisfaction with pain relief at 24h and sleep quality on the first night;Postoperative recovery quality (Qo-15);Incidence of opioid-related side effects (such as nausea, vomiting, itching, etc.);Preoperative blood glucose level.;Postoperative Day 2 Morning 6:00 Blood Glucose Level;Nerve Block Success Rate;Complications related to blockade: such as intravascular injection, systemic toxicity of local anesthetics, hematoma, and nerve injury caused by puncture. Telephone follow-ups will be conducted at 7 days and 1 month postoperatively to document any residual symptoms related to nerve blockade (persistent numbness, paresthesia, or weakness).;Surgery duration, anesthesia duration, intraoperative opioid consumption, and recovery time (from arrival at the recovery room to departure from the recovery room).; | — |
