Ultrasound-guided erector spinae block for postoperative analgesia in thoracotomy patients: a prospective, randomized, observer-blind, controlled clinical trial

Authors

Abstract

Background and objectives
Thoracotomy is considered the most painful of surgical procedures and providing adequate analgesia is the onus for all anaesthesiologists. This study investigated the efficacy of the ultrasound-guided erector spinae plane (ESP) block in analgesia after thoracotomies.
Patients and methods
Sixty patients with American Society of Anesthesiology physical status (ASA-PS) I–IV, aged more than 18 years were allocated to two groups, ESP group which received the ESP block and C (control) group with no block. Single-shot U/S-guided ESP block with 20 ml 0.25% bupivacaine at the 5th thoracic vertebral level was performed preoperatively in the ESP group. Postoperative 24 h morphine consumption and pain scores were compared between the groups. Also, the side effects of opioid usage were compared.
Main results
Postoperative morphine consumption was 22.06 ± 6.24 mg in the ESP group and 30.6 ± 6.23 mg in the C group ( < 0.001). Results showed that there was a significant difference between both groups in favour of the ESP group regarding visual analogue score (VAS) at rest and with coughing ( < 0.001).
Conclusion
Our study findings show that US-guided ESP block exhibits a significant analgesic effect in patients undergoing thoracotomy surgery.
