‘Scheduled’ dosing of lornoxicam provides analgesia superior to that provided by ‘on request’ dosing following craniotomy

Abstract
The aim of this study was to compare the efficacy of ‘scheduled’ analgesia with analgesia ‘on request’ in patients after craniotomy. We performed a prospective randomized study comparing ‘scheduled’ analgesia with analgesia ‘on request’ on 126 patients aged 16–70 years undergoing craniotomy for a variety of reasons. Patients were randomized to one of two groups; group 1 (68 patients) received lornoxicam ‘on request’, and group 2 (58 patients) received 8 mg of lornoxicam preoperatively, immediately after intubation, then 8 mg again 6–8 h after the first injection and 8 mg repeated every 8 h for 48 h postoperatively. Subgroup analysis was performed for patients with supratentorial and infratentorial craniotomy. We measured pain scores (visual analogue scale), mean blood pressure and heart rate at 6, 18, 30, 42 and 54 h after surgery and compared differences in these parameters between groups and amongst subgroups. Group 1 visual analogue pain scale scores were significantly higher than those in group 2 (P 0.05). We found no correlation between visual analogue scale scores, mean blood pressure and heart rate (P > 0.05). ‘Scheduled’ analgesia with lornoxicam was more effective for treating postcraniotomy pain than ‘on request’ analgesia with lornoxicam.
