COMPARISON OF LIGNOCAINE VS LIGNOCAINE + KETOROLAC

Abstract

. Objective: To compare the duration of anaesthesia and degree of analgesia during intravenous
regional anaesthesia using lignocaine alone and lignocaine with ketorolac. Design: This international quasi
experimental study Setting: Nishtar Hospital, Multan. Period: Six months (from June 2004 to November 2004).
Material and Methods: Patients with known allergy to local anaesthesia or keteroloca and with hepatic, renal disease
were not included in the study. Results: Mean pain score at 0,1,2,3,4,5,6 in both groups after release of tourniquet.
The quality of analgesia observed in both groups showed that 20 patients in lignocaine + ketorolac group had excellent
analgesia compared with only 4 patients in lignocaine group. Tourniquet pain was not experienced in any patient in
both groups; owing most probably to the inflation of distal tourniquet cuff on the anaesthetized part of the arm with
release of proximal tourniquet, 10 minutes after injection of solution. Conclusion: It is concluded that 30 mg ketorolac
added to lignocaine in IVRA increases degree of anaesthesia and also provides prolonged postoperative analgesia.
