  "abstract": "Background and Aims Fascial plane blocks can effectively reduce acute pain. Our study aimed to compare the analgesic effects of ESP-block and posterior TAP-block in patients undergoing abdominal hysterectomies and to compare the quality of recovery after anesthesia in different regional anesthesia techniques.Methods A total of 41 patients with ASA status II-III, aged 40–55 years old and who were scheduled for abdominal hysterectomy were included in the trial. All patients underwent general anesthesia with tracheal intubation and mechanical ventilation. Patients were randomized into two groups. In addition to general anesthesia I group received posterior TAP-block ( figure 1), II group received ESP-block (figure 2). Intraoperative fentanyl consumption, daily requirement of morphine after surgery, pain level (with visual analogue scale – VAS) and quality of recovery after anesthesia (with QoR-15 questionnaire) were evaluated. The data was checked for normal distribution and the result was presented as Me [Q1; Q3].Results The total amount of fentanyl perioperatively during abdominal hysterectomy was higher in the I group - 500 [300;700] mcg while in the II group it was 400 [300;700] mcg (p=0.04). There was no significant difference in the duration of anesthesia in the groups. The daily requirement of morphine was 7.5 [2,5;10,0] mg/day in the I group and 5.0 [2,5;10,0] mg/day in the II group (p = 0.003). The VAS values at 1 hour (p = 0.001) and 8 hours after the surgery (p = 0.01) were higher in the I group compared to the II group. There was no statistically significant difference in QoR-15 scores between I and II group (p > 0.05).Conclusions ESP-block demonstrated a higher opioid-sparing effect compared to posterior TAP-block and the level of pain after the surgery was higher in the group where posterior TAP-block was performed. No significant difference was found in quality of recovery after anesthesia scores in two groups.Abstract EP056 Figure 1Posterior TAP-space sonoanatomyAbstract EP056 Figure 2Erector spinae plane block at Th12 level",
