Use of warm local anaesthetic solution for caudal blocks
Abstract:
A double-blind study was undertaken to investigate the effect of prewarmed local anaesthetic solution on the latency of onset of caudal blocks. Forty-four (ASA I-II) patients were allocated into two equal groups. In Group A, the local anaesthetic solutions were injected at room temperature (25 degrees C), while in Group B, they were injected at 37 degrees C. All the caudal blocks were performed using 20 ml of lignocaine 1.5% with adrenaline 1:200,000. The speed of onset of perianal analgesia was found to be significantly faster (39%) with the prewarmed local anaesthetic solution (P < 0.05). No adverse effects were observed.
