Ultrasound Guided Sacral Erector Spinae Plane Block in vNOTES Surgery

Vaginal natural opening transendoscopic surgery (vNOTES) has emerged as a minimally invasive surgical approach in gynecological procedures. By utilizing the vaginal passage as a natural opening, vNOTES eliminates abdominal incisions and has been associated with less postoperative pain, shorter hospital stays, and faster recovery compared to traditional laparoscopic surgery. Despite these advantages, patients undergoing vNOTES may still experience significant perioperative pain due to visceral pelvic manipulation, colpotomy, and uterine traction during the procedure. Recently, sacral modification of ESP block has been described as a promising technique for surgeries involving sacral and perineal regions. Ultrasound-guided sacral ESP block has demonstrated beneficial postoperative analgesic effects in procedures such as pilonidal sinus surgery and other perineal operations. However, the potential role of sacral ESP block in gynecological procedures, particularly in vNOTES surgery, has not yet been sufficiently explored. Pelvic organs receive complex autonomic and somatic innervation, primarily originating from the sacral segments (S2-S4), including the pelvic splanchnic nerves and the pudendal nerve. Targeting these nerve pathways with sacral ESP block can provide effective analgesia for both the visceral and somatic components of pain associated with vNOTES procedures. Therefore, this prospective randomized study aimed to evaluate the effect of ultrasound-guided sacral erector spinae plane block on intraoperative opioid consumption in patients undergoing vNOTES surgery. It was hypothesized that adding sacral ESP block to general anesthesia would reduce intraoperative remifentanil requirements, lower postoperative pain scores, and decrease the amount of analgesics consumed postoperatively. The primary objective of this study was to investigate the effects of sacral ESP block on intraoperative opioid consumption in challenging vNOTES; the secondary objective was to determine its effects on postoperative pain scores and the amount of analgesics consumed.

Comparison of Erector Spinae Plane Block and Caudal Block for Postoperative Analgesia in Pediatric Patients Undergoing Orchiopexy: A Prospective Observational Study

This study aims to compare the analgesic efficacy of ultrasound-guided erector spinae plane block and caudal block for postoperative pain management in pediatric patients undergoing orchiopexy. Postoperative pain scores, time to first rescue analgesic requirement, total analgesic consumption, and block-related adverse effects will be evaluated during the first 24 hours after surgery. The study will assess whether erector spinae plane block provides effective postoperative analgesia comparable to or superior to caudal block in pediatric orchiopexy.

Sacral Erector Spinae Plane Block in Pilonidal Sinus Surgery

This study aims to evaluate the efficacy of ultrasound-guided Sacral Erector Spinae Plane (ESP) block for postoperative analgesia management in patients undergoing pilonidal sinus surgery under general anesthesia

Sacral Erector Spinae Plane Block Versus Penile Block For Analgesia In Pediatric Circumcision

Circumcision is one of the most frequently performed surgical procedures in childhood and is associated with significant postoperative pain. This randomized controlled trial (RCT) aims to compare the analgesic effectiveness of sacral erector spinae plane block (sacral ESPB) and penile nerve block (PNB) in children undergoing circumcision surgery. The primary outcome is postoperative pain, assessed using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale at predefined time intervals within the first 24 hours after surgery. Secondary outcomes include intraoperative analgesic consumption, time to first postoperative analgesic requirement, perioperative hemodynamic changes. The results of this study are expected to provide evidence for selecting the optimal regional analgesic technique for pediatric circumcision surgery.
