Comparison of the Postoperative Effects of the Erector Spinae Plane Block and Local Infiltration Analgesia in Patients Operated with Lumbotomy Surgery Incision: Randomized Clinical Study

The erector spinae plane (ESP) block is a paraspinal fascial plane block.. Local anesthetic drug administration between the tip of the transverse process of vertebra and the anterior fascia of the erector spinae muscles in ESP block . This block is applied under ultrasound guidance. In ESP block, a linear 38-mm, high frequency 10-15 MHz transducer linear usg probe was placed to the 2-3 cm lateral of the T9 vertebral spinous process on the paramedian sagittal plane. The transverse process of the vertebra, trapezius muscle, erector spinae muscle, and subcutaneous tissue were visualized. The plane between the anterior fascia of the erector spina muscle and the T9 vertebra transverse process was aimed from the side to be operated with the lumbotomy incision, with a 22 G 80 mm stimuplex needle, using the in-plane technique. The targeted point was reached by advancing the needle in the caudal and cephalic directions at 45° angles. 10 mL of 0.5% bupivacaine and 10 mL of 2% lidocaine local anesthetic were administered in a controlled manner, carrying out negative aspiration at each 5 mL. The procedure was terminated observing the detached fascial plane after the administration of the local anesthetic solition, Before this block, the anesthetist will review the clinical records again and vital parameters will be closely monitored throughout the procedure. This block will be applied by an experienced anesthesiologist while the patients are under anesthesia and will not be repeated.
