Abstract

Objective: To evaluate the range of sensory block following ultrasound-guided administration of bilateral ESPB at the level of the T7 transverse process with a fixed single dose. Materials and methods: A total of 30 patients undergoing choledocholithiasis surgery at Viet Duc University Hos. from Jan. 2022 to Sep. 2022 received a preoperative bilateral ESP block under ultrasound guidance at the T7 level and were evaluated for the pinprick cutaneous sensation in the anterolateral abdomen and chest wall, and lower extremities at 30 minutes after injection. Results: Thirty patients were enrolled in the study, with the average duration to perform the block procedure being 11.50±2.36 minutes, and the distance from the skin to the erector spinae plane measured under the ultrasound image was 2.17±0.92 cm on average. There were 2 patients with failed blockade. The mean dermatomal spread was 6.43 (range 2 -10), with the majority of patients having cutaneous sensory block from T6 to T9 and over half of patients having sensory block from T4 to T10. No major complication was recorded in the study. Conclusions: Ultrasound-guided erector spinae plane block at the T7 level provided a good sensory block effect, but sensory block varied widely among patients.
