Is this trial a fit for you?
✓Likely a good fit
Adults 18-60 with ASA I-II scheduled for elective laparoscopic cholecystectomy who can receive intraperitoneal injections and do not have contraindications to dexmedetomidine or magnesium.
✕Probably not a fit
Patients with arrhythmias, significant organ impairment, or other exclusions may not experience additional analgesic benefits from these adjuvants.

What this trial studies
This interventional study compares two intraperitoneal adjuvants mixed with bupivacaine during laparoscopic cholecystectomy to see which offers better postoperative analgesia. The design uses two arms: bupivacaine 100 mg with dexmedetomidine 1 mcg/kg and bupivacaine 100 mg with magnesium sulfate 50 mg/kg. Eligible participants are adults aged 18-60 with ASA I-II undergoing elective laparoscopic cholecystectomy under general anesthesia. Outcomes focus on analgesic effectiveness and safety, contributing to multimodal pain strategies in this common procedure.
Why it matters
Potential benefit: If successful, the preferred adjuvant could provide improved pain control and potentially reduce opioid requirements after surgery.
How similar studies have gone: Previous studies have shown potential analgesic benefits for both adjuvants with local anesthetics, but direct intraperitoneal head-to-head comparisons in this setting are limited.
