Objective: To assess the efficacy of warm normal saline distention solution versus a standard, room-temperature normal saline as distention medium for pain relief during outpatient hysteroscopy. Materials and Methods: A prospective randomized case-placebo controlled study was conducted in tertiary care centre - Central Clinical Hospital of Ministry of Interior and Administration. Study group consisted of 100 women referred for outpatient hysteroscopy between January 2015 and July 2015. Every patient, who was referred for an office hysteroscopy, was offered to participate in the study to receive a sterile, 0.9% normal saline warmed up to 36℃ as distention medium. Control group were women receiving sterile, room temperature of 25℃, 0.9% normal saline solution as a distention medium. No pre-medication nor analgesia were used. A visual analogue scale (VAS) was used for one-dimensional pain assessment. Women were asked to mark a VAS score before, during, and five and 15 minutes following the procedure. Results: Median VAS scores during and directly after the anaesthesia-free hysteroscopy were no different between two groups. (p = 0.554 and p = 0.121, respectively). There were also no differences in the procedure time between groups (p = 0.845). Conclusions: Warm normal saline distention solution does not reduce the pain during and at the end of the outpatient hysteroscopy. The effect does not depend on the age of women, menopausal status, parity or type of outpatient hysteroscopy (operative or diagnostic).
