Investigation of the analgesic efficacy of ultrasound-guided thoracolumbar interfacial plane block in vertebral surgery A prospective randomized clinical study

Abstract

Objectives: To investigate the effect of thoracolumbar interfacial plane block)TLIP(on analgesic consumption and pain score in vertebral surgery. Methods: All patients)64 patients undergoing vertebral surgery(were randomly allocated as Group T)patients with block, n=32(and Group C)patients without block, n=32(. After surgery, patient-controlled analgesia using tramadol was administered to all patients. Pain intensity was evaluated with visual analogue scale)VAS; recovery room at 1, 2, 6, 12, and 24 hours postoperative(, and as rescue analgesia, morphine was administered to patients with VAS scores of >4. In this study, total tramadol consumption, the number of patients requiring morphine, VAS score, and Quality of Recovery-40 of all patients questionnaire was evaluated. Results: There were important differences between the 2 groups according to mean postoperative tramadol consumption)Group T and Group C; 180 mg]100-260[vs. 210 mg]100-300[; p=0.001(and the number of patients requiring additional analgesia)n=4; 12.5% vs. n=24; 75%, p=0.000(. There were important differences between the 2 groups according to the postoperative VAS pain score)p=0.000(. Conclusion: Ultrasound-TLIP reduces analgesic consumption and pain severity after vertebral surgery. Therefore, it is an important regional analgesia technique.
