O2502 ROFECOXIBE AND LORNOXICAM AS ADJUNCTS TO MORPHINE BY PATIENT – CONTROLLED ANALGESIA AFTER TOTAL KNEE REPLACEMENT

Abstract

Aim: The purpose of the study is to determine the opioid Ð sparing effect of Rofecoxibe and Lornoxicam in comparison to placebo in total knee arthoplasty. Method: This was a prospective, randomized, double-blind study. 82 patients with mean age of 70 years old (±3.5) and weight 82 (±4) were included. The operation was done under spinal anaesthesia. All patients after the operation were transferred to the Orthopaedic High Dependency unit where PCA morphine with a bolus of 1 mgr and lock-out interval of 8 min was started. There were randomized to receive 50 mgr of Rofecoxibe orally the morning of the operation or 8 mg of Lornoxicam I.V. twice a day. The third group did not receive any additional analgesic. After 24 hours the consumption of morphine and the evaluation of pain according to VAS scale were recorded. The evaluation of pain was done by the same doctor.

Results: There was no statistically signiþcant differences between the three groups either in the consumption of morphine or the pain intensity (Wilcoxon test)Conclusions: Our study showed that the administration of Rofecoxibe 50 mg per os, Lornoxicam 8 mg I.V/b.d. or placebo makes no difference either in the consumption of morphine or the pain intensity during the þrst 24 hours.
