What this trial studies

This clinical trial will enroll women aged 18 and older who are undergoing laparoscopic or robotic hysterectomy procedures. Participants will be randomly assigned to receive either intravenous N-acetylcysteine or a placebo during the first hour of their surgery. Following the procedure, patients will report their pain levels and any pain medication they have taken at various time points. The goal is to evaluate the effectiveness of N-acetylcysteine in reducing opioid use post-surgery.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older scheduled for elective laparoscopic or robotic hysterectomy.

Not a fit: Patients with a history of adverse reactions to acetylcysteine or those with active asthma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to reduced opioid consumption and improved pain management for patients undergoing hysterectomy.

How similar studies have performed: Other studies have shown promise in using N-acetylcysteine for pain management, suggesting potential success for this approach.
