|
|
Aktiv komparator: Ropivacaine group
Patients in this group will receive transversus abdominis plane (TAP) block with Ropivacaine after surgery.
|
Standard-dose ropivacaine administered via ultrasound-guided transversus abdominis plane (TAP) block after laparoscopic cholecystectomy.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Postoperative dynamic NRS pain score at 24 hours
Tidsramme: 24 hours after surgery
|
Postoperative pain intensity under dynamic conditions (e.g., coughing or deep breathing) will be assessed using the Numerical Rating Scale (NRS, 0-10, where 0 = no pain and 10 = worst imaginable pain).

Tidsramme |
|---|---|---|
|
Postoperative NRS pain scores at different time points
Tidsramme: 24, 48, and 72 hours after surgery
|
NRS scores at 24, 48, and 72 hours post-surgery while at rest; NRS scores at 48 and 72 hours while active
|
24, 48, and 72 hours after surgery
|
|
Postoperative recovery quality (QoR-15 scale)
Tidsramme: 24, 48, and 72 hours after surgery
|
Postoperative recovery quality will be evaluated using the 15-item Quality of Recovery (QoR-15) scale at 24 hours after surgery.
The total score ranges from 0 to 150, with higher scores indicating better recovery quality.
|
24, 48, and 72 hours after surgery
|
|
Time to first rescue analgesia
Tidsramme: Up to 72 hours after surgery
|
The time from the end of surgery to the first request for rescue analgesia (e.g., opioid or non-opioid analgesics) will be recorded(background pain is excluded).
|
Up to 72 hours after surgery
|
|
Total postoperative analgesic consumption within 72 hours
Tidsramme: 72 hours after surgery
|
Total amount of rescue analgesics (e.g., opioids, NSAIDs) used by each patient within 72 hours after surgery will be calculated and converted into equivalent doses.
|
72 hours after surgery
|
|
Gastrointestinal function recovery
Tidsramme: Postoperatively, through hospital discharge, up to 7 days after surgery
|
Time to first flatus and time to first defecation, measured from the end of surgery.
|
Postoperatively, through hospital discharge, up to 7 days after surgery
|
|
Postoperative length of hospital stay
Tidsramme: Postoperatively, through hospital discharge (up to 7 days)
|
The total number of days from surgery to hospital discharge will be recorded.
|
Postoperatively, through hospital discharge (up to 7 days)
|
|
Incidence of adverse events
Tidsramme: Postoperatively, through hospital discharge, and at follow-up (up to 7 days after surgery)
|
Adverse events including nausea, vomiting, dizziness, local anesthetic toxicity, and neurological complications will be recorded and compared between groups during hospitalization and follow-up.
