Paracervical block for pain control after vNOTES uterosacral ligament suspension

A Prospective Randomized Double-Blind Placebo-Controlled Trial Evaluating the Effect of Paracervical Block on Postoperative Pain After vNOTES Uterosacral Ligament Suspension

Not applicable Interventional Bakirkoy Dr. Sadi Konuk Research and Training Hospital · NCT07440576

This will test whether a paracervical injection of bupivacaine reduces early postoperative pain in women having vNOTES uterosacral ligament suspension for pelvic organ prolapse.

What this trial studies

This is a single-center, randomized, double-blind, placebo-controlled trial in 58 patients undergoing vNOTES uterosacral ligament suspension for benign indications. Participants are randomized 1:1 to receive a 10 mL paracervical injection of 0.5% bupivacaine or 10 mL normal saline prepared and administered in a blinded fashion. The primary outcome is pain on the Visual Analog Scale at 6 hours after surgery, with additional pain measurements up to 24 hours, total analgesic consumption, length of stay, and patient satisfaction as secondary outcomes. Analyses will follow the intention-to-treat principle.

Who should consider this trial

Good fit: Women aged 18 years or older with symptomatic pelvic organ prolapse scheduled for vNOTES uterosacral ligament suspension (with planned hysterectomy) who are ASA I–III and can give informed consent.

Not a fit: Patients with allergy to bupivacaine or other local anesthetics, chronic opioid use or chronic pain disorders, prior pelvic radiation, severe hepatic/renal impairment, coagulopathy or anticoagulation contraindicating injection, active pelvic infection, pregnancy, or inability to use the pain scale are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, adding a paracervical block could reduce early postoperative pelvic pain and lower short-term opioid needs after vNOTES procedures.

How similar studies have performed: Paracervical block has shown mixed results in other gynecologic procedures, and high-quality randomized data specifically for vNOTES are limited.
