['To test if the simple technique of warming lignocaine reduces the pain of injection during local anaesthetic cataract surgery.', 'Sixty patients undergoing peribulbar local anaesthesia for cataract surgery were allocated randomly to receive either warm (37 degrees C) or cold (room temperature) plain 2% lignocaine for the injection. Pain was assessed subjectively by asking the patients to score their pain from 0 (no pain) to 10 (most severe pain imaginable).', 'The mean pain score for the warm group was 2.3 (SD 1.3) in comparison with a mean score of 5.5 (1.0) for the cold group (p < 0.01).'] Does warming lignocaine reduce the pain of injection during peribulbar local anaesthesia for cataract surgery?
