About

This study included 46 patients who underwent lumbar disc herniation surgery under general anesthesia. After the operation, US-guided ESPB was performed on Group E, and WI was performed on Group W. Postoperative pain was assessed, and the time to first analgesic requirement, total analgesic amount in 24 hours, and side effects were recorded. IBM SPSS Statistics 22 was used for statistical analyses.

46 participants in 2 patient groups

erector spinae plane block

Active Comparator group

Description:

At the end of the surgery, while the patient was still intubated and in the prone position, the linear probe of a Samsung HM70 EVO ultrasound device was placed sagittally, approximately 2-3 cm lateral to the spinal cord. After identifying the erector spinae muscle and transverse processes, a 22-G, 10-mm block needle (Braun Stimuplex Ultra 360, Germany) was advanced posterior to the transverse process after reaching the bone structure. The location of the needle tip was then confirmed, 0.25% bupivacaine (20mL) was injected intermittently, and separation of the erector spinae muscle from the transverse process was observed. The procedure was applied bilaterally (22 patients)

Treatment:

Other: erector spinae plane block(ESPB)

wound infiltration

Active Comparator group

Description:

In Group W, a dose of 0.5% bupivacaine (20 ml) was injected for wound infiltration into the surgery site. (24 patients)

Treatment:

Other: erector spinae plane block(ESPB)
