Comparison of Fluid Capture Efficiency of the Total Capture Drape Versus a Standard Drape for Hysteroscopy

Safety during operative hysteroscopy requires a fluid management system to assist in gauging patient fluid absorption of media used for visualizing the uterine cavity. Serious patient complications, including hyponatremia (low serum sodium), heart failure, and pulmonary and cerebral edema, can result from over absorption of this distending medium. Failure of surgical drapes to collect unabsorbed fluid causes inaccurate determination of the hysteroscopic fluid deficit (HD) thus preventing proper risk evaluation for patient fluid overload, could prompt premature procedure terminatio, and result in hazards for the OR team. Specific Aims: 1. To perform a comparative trial of the "Total Capture" hysteroscopy drape (TCD) versus the standard drape during patient surgeries to document improved, real-time determination of patient fluid absorption. Pilot testing of a prototype design of the "Total Capture drape" versus the conventional hysteroscopy drape indicated remarkable improvement in fluid capture and accurate fluid deficit determination in a plastic pelvic model experiment. 2. To evaluate the clinical usefulness of the TCD compared to the Standard drape for hysteroscopy with the standardized metrics of: 1) the Technology Acceptance Model, and 2) The System Usability Scale. These metrics will allow us to quantitate clinical usefulness and usability of both the operating surgeons and operating room staff. The investigators hypothesize the "Total Capture" Drape design provides an accurate recorded hysteroscopic fluid deficit in real-time so that patient safety and surgical parameters are optimized. The simple design of the TCD would add a very significant improvement for patient safety and care with minimal cost for the estimated 200,000 hysteroscopies performed per year in the U.S.
