Comparison of The Effects of Erector Spina Plane Block and Transversus Abdominis Plane Block Methods on Postoperative Analgesia in Elective Caesarian Section with Ultrasonography Account

Background: The study aimed to compare the efficacy of erector spina plane (ESP) block and transversus abdominis plane (TAP) block in postoperative analgesia in cesarean section operations. Materials and Methods: The study included a total of 90 pregnant women scheduled for elective cesarean section under spinal anesthesia between February 2021 and February 2022. Following the completion of the operation, the patients were randomly assigned to three groups: TAP, ESP, and a control group using a closed envelope technique. Demographic data, postoperative Visual Analog Scale (VAS) scores at 0, 2, 4, 8, 12, and 24 hours, time of first analgesic administration in the patient control analgesia (PCA), the total amount of tramadol consumed, complications, surgeon, and patient satisfaction were recorded. Results: The time of first analgesic administration was statistically significantly lower in the TAP group than in the ESP group (p<0.01). Postoperative tramadol consumption at 0,2,4 and 8 hours was statistically significantly lower in the ESP group than in other groups (p<0.01). At 24 hours, the total amount of tramadol consumed was statistically significantly lower in the ESP group than in other groups (p<0.01). Patient satisfaction was higher in the ESP group compared to the TAP and control groups (p
