Topical anaesthesia in haemodialysis: Evaluation of topical anaesthesia with lidocaine during vascular access in children undergoing long-term haemodialysis for chronic renal failure
Children with chronic renal failure are frequently exposed to painful invasive procedures. Ointments containing lignocaine-prilocaine, when used before intravenous punctures, have been reported to lessen the pain sensation. The aim of this study was to interpret the effectiveness of lidocaine 2.5% ointment in preventing pain when used before venous and arterial punctures in children undergoing a haemodialysis programme for chronic renal failure. Eight children were included in this study. The pain level was identified by the patients using a linear analogue scale. When topical anaesthetic and placebo were compared, there was no statistical difference in interpretation of pain during arterial (P>0.4), venous (P>0.375) or both (P>0.4) procedures. We conclude that lidocaine 2.5% ointment is not effective in preventing pain in children undergoing long-term haemodialysis. In these patients some other factors, like psychological factors, puncture technique and needle size must be taken into consideration for the prevention of pain.
