BackgroundNon-opioid analgesics, paracetamol and non-steroid anti-inflammatory drugs (NSAIDs) are proposed for pain relief after laparoscopy. We compared perioperative propacetamol (P) and ketoprofen (K) to provide analgesia after laparoscopic cholecystectomy.MethodsAfter ethical committee approval, we included 104 ASA I-II patients, without preoperative analgesic drugs, who were scheduled to undergo laparoscopic cholecystectomy. Anaesthesia was standardized using propofol, fentanyl, atracurium, isoflurane and N(2)O 50%. Ketoprofen 100 mg or propacetamol 2 g or a saline drip (a 100-ml unit of saline in 10 min) was infused blindly and randomly. Patients received either ketoprofen (group K1) or propacetamol (group P1) before induction of anaesthesia and saline after surgery, or saline before surgery and ketoprofen (group K2) or propacetamol (group P2) after surgery. Postoperative visual analogue pain scores (VAS 0-100 mm) were recorded during 24 h. If VAS was >30, a second dose (placebo, ketoprofen or propacetamol) was infused. Nalbuphine 0.2 mg kg(-1) i.v. was given as rescue analgesic if VAS was > or =50.ResultsNinety-eight patients were studied The number of patients not requiring the second analgesic was greater in K1 (33.5%) than the others (K2 0%, P1 0%, P2 7.5%). VAS scores were significantly lower in K1 (P=0.001), with less nalbuphine consumption compared with P1. VAS and opioid request were similar in K2 and P2.ConclusionPreoperative administration of ketoprofen improves postoperative analgesia after laparoscopic cholecystectomy compared with its postoperative administration and pre- and postoperative propacetamol.
