Abstract

Objective: To evaluate the analgesic efficacy of bilateral erector spinae plane (ESP) block using 0.25% ropivacaine for postoperative pain management after cesarean delivery. Materials and Methods: This randomized controlled clinical trial included 60 parturients undergoing cesarean section under spinal anesthesia. Participants were allocated into two groups: Group N1 (control) received no regional block, while Group N2 (ESP group) received bilateral ESP blocks at the T9 level with 20 mL of 0.25% ropivacaine per side. All patients were subsequently provided with morphine patient-controlled analgesia (PCA). Results: The ESP group demonstrated a significantly longer time to first analgesic request compared to the control group (210.1 ± 35.3 minutes vs. 67.6 ± 21.3 minutes). Total morphine consumption during the first 24 hours and between 24–48 hours postoperatively was significantly lower in the ESP group. Additionally, ESP block reduced visual analog scale (VAS) pain scores at rest and during movement within the first 24 hours postoperatively. Patient satisfaction scores were also higher in the ESP group compared to controls. Conclusion: Bilateral ESP block is an effective analgesic technique for cesarean delivery, reducing opioid requirements and improving patient satisfaction after surgery.
