The effect of needle size and type in paediatric caudal analgesia.

A randomized prospective study compared three types of needle for caudal analgesia in 623 children. Inadvertent vascular puncture (bloody tap) was more likely if a child weighed more than 15 kg. There were no significant differences in respect to success or complication rate between the needle types (21 g and 23 g standard bevelled intramuscular (i.m.) needles and 22 g short bevelled 'regional block' needle).
