Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Erector spinae plane (ESP) block Technique: It is a single shot technique performed by an anesthetist ( one of the investigators) at the beginning of the surgical procedure in the operation room. An in-plane approach in the prone position will be attempted under the ultrasound guidance. Using a 6- to 15-MHz high-frequency linear probe, Erector spinae (ES) muscles will be visualized at the L3 transverse process 22g needle will be used to locate ES, after saline test dose 0.25% bupivacaine (20 mL per side) will be administered. This ESP block is monitored in the recovery room and assessed how effective in providing postoperative pain relief in lumbar disc hernia surgery.

Prevention
Comparator / control treatment
The erector spinae plane (ESP) block will not be applied to the control group. Remifentanil (0.25 – 0.5 mcg kg-1 min) will be used for intraoperative analgesia. Tramadol (1 mg kg-1) and paracetamol (1g) will be used for postoperative analgesia.
Control group
Active

Statistical methods / analysis
The data will be analysed using the following methods: differences between the
continuous variables by the “t”-test; categorical variables by Fisher's exact test. For data without normal distribution, Mann Whitney U test was performed. Ratios were compared using Chi Square. Categorical variables were compared using Fisher exact test. A p-value of<0.05 was considered statistically significant.

Summary
Brief summary
The study will be conducted at the University of Health Sciences Erzurum Regional Education and Research Hospital with patients who are scheduled for elective lumbar disc hernia surgery. This study aimed to evaluate the effect of erector spinae plane (ESP) block on postoperative pain levels. Efficiency is assessed by pain score, analgesic use, and other outcomes.
We hypothesize; that ultrasound-guided ESP block in lumbar disc hernia operation will reduce postoperative pain level.
