Optimal visualization of the uterine cavity is essential for both diagnostic and operative hysteroscopy. It relies on effective distension, achieved by delivering irrigation fluid at an appropriate pressure.
Insufficient pressure can limit visualization, while excessive pressure may increase patient discomfort or lead to excessive fluid absorption. The challenge is to maintain effective and stable distension throughout the procedure.
Why is stable distension so important?
During hysteroscopy, intrauterine pressure constantly fluctuates due to fluid loss through the cervix, instrument insertion, and suction during the procedure.
Pressure that is too low can cause partial collapse of the uterine cavity and impair visibility, particularly when bleeding occurs. Conversely, excessive pressure may increase fluid absorption.
Maintaining appropriate pressure, ideally close to the patient’s mean arterial pressure, helps balance optimal visualization and procedural safety.
Which parameters influence distension quality?
Distension quality depends on several complementary factors:
- Pressure adapted to the type of procedure;
- Sufficient flow to compensate for fluid loss;
- Constant pressure to minimize fluctuations.
Controlling these parameters helps maintain optimal working conditions throughout the procedure.
Why use a fluid management system?
Electronic fluid management systems automatically regulate pressure and flow throughout the procedure. They compensate for fluid loss and reduce the need for constant manual adjustments, helping maintain consistent uterine distension and facilitating irrigation parameter monitoring.
These systems are valuable for both diagnostic hysteroscopy and longer or more complex operative procedures.
The iFlow mini Solution
To meet these needs, Delmont imaging has developed iFlow mini, a compact fluid management solution designed for diagnostic and operative hysteroscopy.
With automated pressure control, continuous automatic flow adjustment, and a constant-pressure system, iFlow mini helps maintain a stable uterine cavity throughout the procedure. Its intuitive interface and compact design make it easy to use in both dedicated examination rooms and operating theatres.
An efficient fluid management system helps optimize working conditions for medical teams while contributing to the quality and safety of hysteroscopic procedures.
