Analgesic Effect of Erector Spinae Plane Block at T2 Level in Arm Surgery

ABSTRACT

Erector spinae plane block (ESPB) has been performed as a method of postoperative analgesia for breast, thoracic, and abdominal surgery. Most of those cases were carried out at T4–7 level and the main targets for postoperative analgesia were the thoracic nerves. However, there are few studies on the effect of ESPB on the cervical nerves. We report that ESPB at the T2 level was effective for postoperative pain management of arm surgery due to the blocking effect of thoracic and cervical nerve.
