Randomized Controlled Trial Comparative Study
Ultrasound-guided versus conventional injection for caudal block in children: A prospective randomized clinical study.
The aim of this study was to compare the efficacies of ultrasound guided sacral hiatus injection and conventional sacral canal injection performed for caudal block in children. ⋯ Despite the limitations in central neuroaxial anesthesia we recommend the use of ultrasound since it reduces the complications and increases the success rate of first puncture in pediatric caudal injection.
