Investigation of Analgesic Efficacy of Thoracolumbar Interfascial Plane Block in Vertebral Surgery

Thoracolumbar interfascial plane block has successfully been demonstrated to provide an efficient analgesia in patients. The present study is aimed to investigate the intraoperative hemodynamic responses, anesthetic and analgesic consumption, and postoperative recovery quality of thoracolumbar interfascial plane block in patients with vertebral surgery. After approval, patients enrolled in the study are divided into two groups by computer-based randomization technique as control and study group. After standard monitorization, anesthesia induction and tracheal intubation, erector spinae plane block is performed to study group and no intervention to control group.

In the intraoperative period, 10 mg / kg paracetamol and 0.05 mg / kg morphine will be used for postoperative analgesia. After surgery, all patients will be given 10 mg/kg paracetamol every 8 hours and will be fitted with a patient-controlled analgesia (PCA) device (Tramadol HCL). PCA device bolus dose will be set to 20 mg, lock time will be set to 10 minutes and the number of buttons per hour will be set as 3.for postoperative analgesia.After surgery, VAS scores of the patients will be evaluated (in the recovery room, 1,3,6,12 and 24 hours, Patients with VAS>4 will be given 0.03mg / kg morphine as salvage analgesia.After 30 minutes, the patients' VAS will be re-evaluated,If VAS>4 the same dose will be repeated. A patient satisfaction questionnaire (Qr40)will be filled by patients at the postoperative 24th hour.
