The postoperative analgesic effect of ultrason-guided transversus abdominis plane block for patients undergoing total abdominal hysterectomy [Total abdomi̇nal hi̇sterektomi̇ olgularinda ultrason tekni̇ǧi eşli̇gnde yapilan transversus abdomi̇ni̇s düzlem bloǧunun postoperati̇f analjezi̇k etki̇nli̇ǧi̇]

Background: transversus abdominis plane (tap) block is an effective method of providing postoperative analgesia in patients undergoing abdominal surgery. we evaluated the analgesic efficacy of the ultrasound-guided tap block with compared epidural analgesia in patients undergoing total abdominal hysterectomy under spinal anesthesia. methods: a randomized,double-blind trial was performed at a tertiary hospital. forty patients were randomized to receive spinal anesthesia and epidural analgesia either without (group i,n=20) or with tap block (group ii,n=20). bilateral tap block was performed with bupivacaine 0.25%. all participants received spinal anesthesia with bupivacaine,followed by postoperative patient-controlled epidural levobupivacaine+fentanyl. postoperative demand of levobupivacaine+fentanyl,average pain scores,nausea,vomiting,urinary retention,hypotension,satisfaction with pain relief was recorded. results: total levobupivacaine + fentanyl use in 48 hours was reduced in group ii (mean ± sd levobupivacaine: 150±43 mg and fentanyl: 240±68 μg) compared with group i (mean ± sd levobupivacaine: 428±90 mg and fentanyl: 685±145 μg) (p<0.05). vas scores were significantly lower in group ii at all times,than in group i (p<0.05). conclusions: the ultrasound-guided tap block reduces levobupivacaine+fentanyl requirements,decreases pain scores and increases patient satisfaction after total abdominal hysterectomy.
