The impact of altering filling pressures in diagnostic outpatient hysteroscopy on the procedure completion rates and associated pain: a randomised double‐blind controlled trial

Abstract

Uterine filling pressure of 50 mm Hg was associated with better visualisation than 30 mm Hg and lower pain scores than that of 80 mmHg with no difference in the proportion of completed procedures.

A randomized double‐blind controlled trial of different filling pressures in operative outpatient hysteroscopy

“…The present results are in agreement with a previous randomized trial that included 240 women undergoing diagnostic hysteroscopy and compared uterine filling pressures of 30, 60, and 80 mm Hg. In that study, pain scores increased progressively with increasing pressure, whereas visibility was lowest in the group with a filling pressure of 30 mm Hg.…”

“…Operative hysteroscopy was performed as described previously using a vaginoscopic approach. Saline at room temperature was used as the distention medium, with an even pressure maintained by an automated pressurized pump.…”

“…Studies comparing different uterine filling pressures have only been performed for diagnostic procedures . To the best of our knowledge, no studies have compared different uterine filling pressures during operative outpatient hysteroscopy.…”

“…19,20 Studies comparing different uterine filling pressures have only been performed for diagnostic procedures. 18,21 To the best of our knowledge, no studies have compared different uterine filling pressures during operative outpatient hysteroscopy. The outcomes from studies on diagnostic hysteroscopy cannot be applied to operative hysteroscopy because the latter is usually longer and associated with greater discomfort.…”

What should the optimal intrauterine pressure be during outpatient diagnostic hysteroscopy? A randomized comparative study

“…Many published studies have evaluated the use of different pain‐management strategies. However, view studies investigating optimal intrauterine filling pressure have been performed in outpatient HSC only, and only two studies were randomized trials conducted from a diagnostic HSC perspective . From the published work, we have concluded that there are two reasonable options for evaluating intrauterine filling pressure in outpatient HSC, namely low pressure states (30–50 mmHg) and high‐pressure states (70–100 mmHg).…”
