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

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]; =0.001) and the number of patients requiring additional analgesia (n=4; 12.5% vs. n=24; 75%, =0.000). There were important differences between the 2 groups according to the postoperative VAS pain score (=0.000).

CONCLUSION

Ultrasound-TLIP reduces analgesic consumption and pain severity after vertebral surgery. Therefore, it is an important regional analgesia technique. CLINICALTRIALSGOV GRANT NO: .
