Is this trial a fit for you?

Likely a good fit

Adults aged 18 years or older scheduled for total laparoscopic hysterectomy at Mount Sinai Hospital who do not meet the exclusion criteria are eligible.

Probably not a fit

Patients with prior presacral neurectomy, chronic opioid use, fibromyalgia, BMI >50, advanced gynecologic cancer, or who cannot communicate or consent (including language barriers) are excluded and unlikely to benefit from this intervention.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-center, parallel-group, randomized controlled phase 2 trial comparing a presacral nerve block with 20 mL ropivacaine (5.0 mg/mL) to a 20 mL normal saline sham given at the time of total laparoscopic hysterectomy. Sixty patients will be randomized 1:1, with study syringes prepared and labeled by a clinic nurse unaffiliated with other study activities to maintain blinding. Participants are recruited by convenience sampling from Mount Sinai Hospital outpatient gynecology clinics and provide informed consent before surgery. The trial's primary focus is post-operative pain after surgery, with collection of related outcomes such as analgesic use.

Why it matters

Potential benefit: If successful, the presacral nerve block could reduce post-operative pain and lower opioid requirements after laparoscopic hysterectomy.

How similar studies have gone: A prior report by Rapp et al. used a similar 20 mL ropivacaine instillation at open hysterectomy with suggestive results, but randomized data for presacral block in laparoscopic hysterectomy remain limited.
