Background: This study aimed to investigate the effects of tranversus abdominis plane (TAP) block placed postoperatively using ultrasound guidance for patients with caesarean section, myomectomy, and hysterectomy under general anesthesia by eliminating additional pain caused by surgical incision. Methodology: The study has been planned to investigate the postoperative analgesia of 50 patients with TAP blocks applied and non-applied between the ages of 18-65, who will pass abdominal surgery. The study has been conducted in a prospective, randomized and controlled manner. Patients have been classified as those who have undergone TAP block (group: I) and those without block (group: II). Results: Mean age of the patients in the TAP block group was 35.52 years, the mean age of the other group was 32 years and there was no statistically significant difference. The patients' visual analog scale (VAS) was evaluated at the 30th minute, 1st, 2nd, 6th, 12th, and 24th hours in the postoperative period. For patients with TAP blocks, the VAS score was found to be lower for all hours than patients without TAP blocks (p<0.05). Beginning at the 30th minute and 1st-hour analgesic needs of the block patients were compared with the other group (p<0.05). Conclusion: TAP, that can be easily and safely placed provides effective analgesia and reduces the additional disruptions caused by the pain.
