Does temperature of distending medium matter in outpatient hysteroscopy? A double-blinded cohort control observational study of room temperature versus warmed saline.

Aim: There is little data assessing outcomes of outpatient hysteroscopy using warmed versus room temperature saline. The aim of this study was to determine if the temperature of the distending medium during outpatient hysteroscopy affect ease of procedure, clarity of view, procedural discomfort/pain and patient satisfaction.

Methods: This was a double-blinded cohort control quasi-randomized prospective study involving 100 women undergoing outpatient diagnostic and operative hysteroscopy for abnormal uterine bleeding, intrauterine contraceptive devices retrieval and removal of endometrial polyps.
