Erector Spinae Plane Block for Postoperative Pain Management

The Effect of Erector Spinae Block for Postoperative Pain Management Cesarean Delivery Patients

Erector spinae plane (ESP) block is an interfacial plane block with visceral and somatic analgesic activity at paraspinal muscles. This study aims to examine the postoperative analgesic efficacy of ESP block after cesarean section (CS) with Pfannenstiel incision under spinal anesthesia.

The study included 54 patients with mild systemic disease (ASA II patients) who would undergo elective CS under spinal anesthesia. They were randomly divided into an ESP block group (Group E) and a control group (Group C). After the surgery, Group E patients underwent ultrasound-guided bilateral ESP block with 20 ml of 0.25% bupivacaine at the lateral decubitus position, while Group C received no intervention. Patients in both groups received parenteral patient-controlled analgesia. The patients' post-operative 24-hour opioid consumption, regular Visual Analogue Scale (VAS) measurements, and need for rescue analgesics were evaluated. Statistical analysis was performed using SPSS 21 program. Demographic and other data were assessed using independent samples t-test, Mann-Whitney U test, and Chi-square analysis.
