Hyskon is used as an intrauterine instillation fluid during hysteroscopy to allow clear visualization of the uterine cavity during diagnostic and surgical procedures. It may also serve as an adjuvant in fertility treatments and is sometimes used as a culture medium in embryology laboratories.
Hyskon is a high-molecular-weight dextran solution that is instilled into the uterine cavity to distend the walls, creating space and optical clarity for visualization during endoscopic procedures. Its viscous nature helps maintain uterine distension while being relatively non-absorbable by uterine tissue.
Hyskon is intended solely for intrauterine use and must not be administered intravenously. Severe allergic reactions, including anaphylaxis, have been reported. Caution is needed in patients with active uterine bleeding, cervical stenosis, or known dextran hypersensitivity. Equipment compatibility should be verified before use, as dextran may damage certain optical instruments.
