Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial asks whether using saline warmed to body temperature (37°C) during outpatient hysteroscopy—a procedure to look inside the uterus—can reduce pain compared with saline at room temperature. Women aged 18 to 70 scheduled for diagnostic hysteroscopy will be randomly assigned to receive either warm or room-temperature saline. Pain scores will be compared during the procedure and one hour later, along with the need for extra pain relief. The hope is that a simple temperature change could make the experience more comfortable.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Warmed saline at 37°C used as a uterine distension medium during hysteroscopy
What this could lead to
If warm saline works, it could offer a simple, low-cost way to make outpatient hysteroscopy more comfortable and reduce the need for pain medication.
What could go wrong
This is a small, early-stage trial, and the benefit may be modest or not clearly better than room-temperature saline. Pain is subjective, and results may not apply to all women.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 60 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18-70 years. * Ability to understand and report pain using the Visual Analog Scale. * Willingness to undergo outpatient hysteroscopy and provide written informed consent. Exclusion Criteria: * Congenital genital tract malformations: including these patients could introduce a confounding factor because pain may result from difficult anatomy rather than the temperature of the distension medium. * Previous hysteroscopic procedures: pain perception may be influenced by prior experience rather than the intervention itself * Suspected pregnancy: standard gynecologic practice considers pregnancy a contraindication to elective diagnostic hysteroscopy * Active pelvic infection: instrumentation of an infected genital tract may increase morbidity and facilitate ascending infection. Also, pain scores may reflect infection-related pain rather than procedural pain.
