paracetamol instead of ketorolac in post-video-assisted thoracic surgery pain management: a randomized trial

conclusions paracetamol 1 g stat + 3 g/24 h infusion is as effective as ketorolac 30 mg stat + 90 mg/24 h infusion in post-vats pain management, with good tolerability and a low incidence of adverse effects. results there was no significant difference between the k and p groups in pain scores in any of the evaluations. seventeen (48.6 %) and 9 (25.7 %) patients in the k and p groups, respectively, did not require any rescue analgesia (p = 0.047). the mean doses of rescue analgesia in the k and p groups were 3.129 ± 4.27 mg and 4.38 ± 3.69 mg, respectively, which were similar (p = 0.144). there was no significant difference between the groups in satisfaction scores (p = 0.175). objectives the aim of the present study was to compare the analgesic effects of paracetamol and ketorolac in vats patients. methods this was a double-blinded randomized clinical trial conducted on 70 patients undergoing lobectomy or segmentectomy due to lung masses, using video-assisted methods. the patients were randomly divided into two groups (each n = 35): the ketorolac (k) group and the paracetamol (p) group. the k group received ketorolac 30 mg iv stat at the end of surgery and then a 90 mg/24 h infusion. the p group received paracetamol 1 g iv stat at the end of surgery and then a 3 g/24 h infusion. pain scores were recorded during recovery and 2, 4, 8, 12, and 24 hours after drug administration. pain scores, total doses of rescue analgesics, and patient satisfaction levels were compared between the groups. background video-assisted thoracic surgery (vats) is a minimally invasive procedure that is growing more common around the world. despite causing less pain compared open thoracic surgery, postoperative pain management is still important.
