An interventional study of ESPB and PVB in Nerve Block, sponsored by Giresun University. Completed at 1 site in Turkey. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2023-05-03.
Sponsored by Giresun University · Not applicable, Interventional, and Diagnostic
Erector spinae plane (ESP) block is a more recent method than paravertebral block (PVB) and has a lower risk of complications. The aim of this study was to compare postoperative analgesia requirements and side-effects in terms of safely reaching the maximum analgesic effect in patients.
The primary aim of this study was to compare ESP block and PVB as important postoperative pain management in terms of being able to reliably reach the highest analgesic efficacy in patients who underwent laparoscopic surgery which is a frequently applied surgery. The secondary aim was to determine the incidence of postoperative nausea, vomiting and side-effects, and patient satisfaction.

Exclusion Criteria:
The spinous processes of the vertebrae were marked up to T8 level. After providing antisepsis of the skin with 10% povidone iodine, the ultrasound probe was placed at T8 level parallel to the vertebral spine at T8. The transverse process (TP) and hyperechoic pleura were observed 2.5cm right lateral of the spinous process. Using the in-plane approach, the needle was placed in the caudal direction. After confirming displacement of the pleura with 0.5-1ml local anaesthetic (LA), 20ml 0.25% bupivacaine was administered for the block .
Procedure: ESPB
After sterilisation of the skin with povidone iodine, the probe covered with a sterile sheath was placed 3cm lateral of the T8 spinous process. The trapezius, rhomboid major, and erector spinae muscles, and the TP of the vertebrae were visualised. The needle was placed craniocaudally within the fascial plane of the deep surface of the erector spina muscle above the bone shadow of the TP. The fluid dissemination was confirmed by raising the placement of the needle tip towards the erector spina muscle. 20ml 0.25% bupivacaine was applied to this region and the spread of local anaesthetic was observed
