Bier's block; comparison of lignocaine vs lignocaine + ketorolac

To compare the duration of anaesthesia and degree of analgesia during intravenous regional anaesthesia using lignocaine alone and lignocaine with ketorolac. This international quasi experimental study. Nishtar Hospital, Multan. Six months [from June 2004 to November 2004]. Patients with known allergy to local anaesthesia or keteroloca and with hepatic, renal disease were not included in the study. 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. It is concluded that 30 mg ketorolac added to lignocaine in IVRA increases degree of anaesthesia and also provides prolonged postoperative analgesia
