Caudal Epidural Block

Brief summary

Park et al. reported the results of a randomized study of the use of ultrasound and the use of C-arm in caudal epidural block. However, it is difficult to determine the overall epidural space contrast agent spread with ultrasound alone, and intravascular injection can be avoided with ultrasound. It was said that the evidence for the efficacy of exclusion of intravascular infusion was not as good as that of the C-arm. Therefore, it was suggested that ultrasound in caudal epidural block should be considered only when it is difficult to use the C-arm as an auxiliary means to guide the needle when the sacral hiatus is less than 2 mm and has a complex anatomical structure. The purpose of this study is to determine the difference between intravascular injection and epidural spread according to the type of needle during caudal block under ultrasound guidance.
