AbstractOne hundred unpremedicated fit day surgery patients aged between 27 and 68 years were allocated randomly into one of four groups and EMLA, glyceryl trinitrate, EMLA and glyceryl trinitrate or a placebo ointment was applied to the dorsum of a hand. The pain and ease of venepuncture were determined at induction of anaesthesia 60 minutes later. Pain scores were also reassessed 1-2 hours after operation. Lower pain scores and easier venepuncture occurred when EMLA and glyceryl trinitrate ointment was applied to the dorsum of the hand.
