Brief Summary:
The goal of this pilot cross sectional study is to identify participants at risk of vasovagal reaction/syncope(VVR/VVS) during office hysteroscopy. A predictive red flag classification system is being studied to improve procedural safety during office hysteroscopy. Researchers will perform office hysteroscopy as per the standard protocol by vaginoscopic technique. A nurse positioned at the head side of the participant will record signs and symptoms of VVR/VVS. The participant will be asked of the severity of the pain experienced during office hysteroscopy in relation to their menstrual cycle. The procedure will be discontinued at any point the participant wishes to stop.
Detailed Description:
Office hysteroscopy is increasingly utilized due to advancements in instrumentation and techniques; however, its adoption in routine gynecologic practice remains limited to 10-12% of cases. This under utilization is largely attributed to the perception of pain and lack of financial incentives. Consequently, fewer than 20% of gynecologists employ office hysteroscopy for the evaluation of intrauterine pathology.
Although generally safe, vasovagal syncope (VVS) is the most concerning complication, with a reported prevalence ranging from 0.21% to 1.85%. Other complications include pain, infection, and bleeding. Surgeons often fail to anticipate vasovagal responses during the procedure. This study aims to develop a red flag classification system based on pain response to enable early recognition and prevention of VVS during office hysteroscopy.
Research design This is a multicenter, cross-sectional, analytical pilot study enrolling women undergoing office hysteroscopy over 4 months.
Sample Size Calculation Based on an estimated VVS rate of 6.3%, and using a 95% confidence interval, the sample size of 46 was calculated using Crutzen's online tool.
Statistical Analysis Descriptive analysis will be conducted for continuous and categorical variables. Chi-square tests will evaluate the association between pain classification and vasovagal events. The STROBE checklist will guide reporting.
