BackgroundPain after laparoscopic cholecystectomy (LCC) is multifactorial. Effective post-operative pain control is necessary in LCC performed as day-case surgery. We studied the efficacy of paracetamol or valdecoxib with or without dexamethasone after LCC.MethodsOne hundred sixty patients were randomized to four groups of 40 patients. Groups 1 and 3 received parecoxib 40 mg intravenously (IV) during surgery and valdecoxib 40 mg x 1 per os (PO) for 7 post-operative days. Groups 2 and 4 received paracetamol 1 g x 4 IV during surgery and 1 g x 4 PO for 7 days. In addition, Groups 3 and 4 were given dexamethasone 10 mg IV intra-operatively. Propofol and remifentanil were used during surgery. The patients were given oxycodone 0.05 mg/kg IV in phase 1 post-anaesthesia care unit (PACU 1) or 0.15 mg/kg PO in phase 2 post-anaesthesia care unit (PACU 2) as needed to keep visual analogue scale <3/10. The patients were supplied with the study drugs for 7 post-operative days.ResultsPain intensity, nausea and the need of oxycodone in phase 1 PACU were similar in all groups. Dexamethasone reduced the need of oral oxycodone in phase 2 PACU (7.0 +/- 1.0 mg vs. 9.1 +/- 1.0 mg, P<0.05). Pain intensity was similar in all groups at home. More patients in the parecoxib/valdecoxib groups needed rescue medication on the 1st post-operative day (P<0.001) than paracetamol-treated patients.ConclusionParacetamol was as effective as parecoxib/valdecoxib for pain after LCC. Dexamethasone decreased the need of oxycodone in phase 2 PACU. The effect of dexamethasone was similar in paracetamol and parecoxib/valdecoxib patients.
