What this trial studies

This clinical trial evaluates the effectiveness of topical lidocaine compared to a placebo in managing pain during manual vacuum aspiration (MVA) for patients with endometrial thickening. It is a prospective, randomized, double-blind, placebo-controlled trial involving 126 participants, divided into two groups. The study will assess pain perception using a visual analog pain scale before, during, and after the MVA procedure, which is performed in the emergency area of Obstetrics and Gynecology. The trial aims to improve pain management protocols for women undergoing this common procedure.

Who should consider this trial

Good fit: Ideal candidates include women over 40 years old with endometrial thickening or abnormal uterine bleeding who can provide informed consent.

Not a fit: Patients who are pregnant, breastfeeding, or have severe cardiovascular diseases will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for women undergoing manual vacuum aspiration.

How similar studies have performed: Previous studies have shown the effectiveness of lidocaine in pain management during similar procedures, suggesting a positive outlook for this approach.
