Comparison of the efficacy of modified thoracolumbar interfacial plane block (mTLIP) and erector spinae plane block (ESP) for preemptive analgesia in lumbar discectomy surgery

Modified thoracolumbar plane block (mTLIP): under ultrasound-guided, the lateral compartment of the longissimus muscle and iliocostal muscle muscles are imagined and the block needle is placed in the interfascial plane of these two muscles and local anesthesic solution is appliced. - 20 ml of 0.25% bupivacaine will be used on each side (total of 40 ml of 0.25% bupivacaine will be used) - to be administered only approximately 20-30 minutes before the onset of anaesthesia. - only once in the preoperative block room approximately 20-30 minutes before induction of anaesthesia - plane block applications will be performed by anaesthesiologists with at least 5 years of experience - patients' intraoperative fentanyl consumption, agitation-sedation scores on awakening from anaesthesia, tramadol consumption in the postoperative 24 hours, postoperative VAS pain scores, and side effects such as postoperative nausea-vomiting will be evaluated. - plane blocks will be applied under ultrasound guidance. - plane block applications will be performed by anaesthesiologists with at least 5 years of experience - Postoperative evaluations of patients will be performed face to face. Patients will be routinely administered 1 g paracetamol intravenously at 8 hour intervals in the postoperative period. 100 mg tramadol intravenously will be administered if their pain is above VAS 4 despite this. - This study was followed up in the neurosurgery unit of SBU Gazi Yasargil Training and Research Hospital. - Patients were sedated with 1 mg midazolam and 50 mcg fentanyl intravenously in the preoperative preparation room in the operating room and 20 ml of 0.25% bupivacaine was administered bilaterally on each side under ultrasound guidance. After the block application, the patient was taken to the operating room and standard general anaesthesia was applied. Patients will be monitored for pain and side effects at the neurosurgery unit , 1st hour, 2nd hour, 4th hour, 8th hour and 24th hour in the postoperative period. - Both plan blocks are applied for analgesia in the postoperative period and aim to reduce opioid consumption in the postoperative period.
