Sensorial Block Assessment of Erector Spinae Block

Ultrasound-guided erector spinae plane blocks are used as postoperative analgesia method for abdominal, chest and hip surgeries. Regional techniques are well-described methods for postoperative analgesia. However, the sensorial dermatomal spread of regional block varies depending on the multiple variables as the level of the block, local analgesic concentration etc. The aim of this study is to observe dermatomal evaluation of sensorial block.
