ClinConnect Summary

This clinical trial is studying a new way to predict who might faint or feel very lightheaded during a common procedure called office hysteroscopy, which is used to look inside the uterus. The researchers want to develop a “red flag” system to identify people at higher risk of these reactions so that the procedure can be made safer. During the study, women will undergo the hysteroscopy using a gentle technique, and a nurse will carefully watch for any signs of fainting or discomfort. Participants will also be asked how much pain they feel and whether it changes depending on their menstrual cycle. If at any time a participant wants to stop the procedure, it will be stopped immediately.

Women aged 18 and older who have had gynecological care before and can give consent are eligible to join. However, women who cannot consent, have certain mental health conditions or take anxiety medications, use stronger anesthesia, or have a family history of fainting spells are not eligible. This study aims to help doctors better understand who might be at risk during office hysteroscopy and improve safety for future patients.
