Ultrasound Guided Investigation Of The Anatomical Features For Caudal Block In Children With Sacral Dimple

Study Overview
=================
Brief Summary
-----------------
When dimples are detected in the sacral region, most practitioners consider it to be a sign of spinal anomaly and avoid caudal block. Ultrasound guided investigation of the anatomical features for caudal block in normal children and in children with sacral dimple will be informative for practitioners.

Detailed Description
-----------------
A dimple over the sacrum may be an isolated finding or a sign of underlying spinal abnormality. Therefore, most practitioners are confused to perform a caudal block. Ultrasonography is a safe and cost effective screening tool in pediatric patients. Ultrasound guided investigation of the anatomical features of sacral region may play a key role to eliminate suspicions. It is possible to detect spinal abnormalities and also measuring dural sac level, distance between dural sac and estimated needle insertion site or needle entry angle. In this study, we will examine whether there is a difference between normal children and children with dimple in the sacral region.
