BACKGROUND AND OBJECTIVE: We compared the efficacy of intravenous lornoxicam vs. dipyrone in patient-controlled analgesia for postoperative analgesia. METHODS: The study included 105 patients who had undergone elective septorhinoplasty after receiving general anaesthesia. Patients were divided into three groups to receive lornoxicam (24 mg day(-1)), dipyrone (5 g day(-1)) or placebo. Pain was evaluated using a 0-100 mm visual analogue scale at 2, 4, 6, 8, 12, 16, 20 and 24 h postoperatively. Pethidine (1 mg kg(-1)) was administered intramuscularly to patients requiring rescue analgesia. Pethidine requirements were recorded during the first 24 h postoperatively, and treatment-related adverse effects were noted. RESULTS: Postoperative pain scores were significantly lower with lornoxicam compared with dipyrone at 8 h (P = 0.016). No significant differences regarding pain scores at 2, 4, 6, 12, 16, 20 and 24 h were found. Significantly fewer patients in the lornoxicam group required rescue analgesics (vs. dipyrone, P = 0.046; vs. placebo, P = 0.001); fewer patients in the dipyrone group required rescue analgesics compared with placebo (P = 0.008). Significantly fewer patients in the lornoxicam group had nausea (vs. dipyrone, P = 0.022; vs. placebo, P = 0.006); no significant differences were found between the other two groups. Antiemetic use was significantly lower in the lornoxicam group (vs. dipyrone, P = 0.002; vs. placebo, P = 0.001). CONCLUSIONS: Lornoxicam has better tolerability and is a more effective analgesic than dipyrone when administered by patient-controlled analgesia for postoperative analgesia after septorhinoplasty.
