IVF success rate in mind

EXPOSURE TO TOXIC DISINFECTANT CAN IMPACT IVF SUCCESS RATE

The risk of exposure to toxic residuals can impact oocyte retrieval, embryo transfer and other IVF applications during pelvis ultrasound probe procedures (1-9)

In a study conducted at FDA’s Office of Science and Technology, it measured the integrity on cellular membrane, metabolic activity or cell growth and found that there was several hundredfold difference in the relative toxicity of various disinfecting substances. The liquid disinfecting agents were classified into three main groups according to their relative toxicity:2

  • Mild (TC(50) > 1 mM, including phenol, hydrogen peroxide (30% w/v), and formaldehyde (37% w/v))

  • Moderate (1mM > TC(50) > 0.1 mM, Sodium hypochlorite (4% w/v))

  • Severe (TC(50) < 0.1 mM, glutaraldehyde (50% w/v), cupric ascorbate, and peracetic acid (32% w/v)) toxicity.

The Sonex/NanoNebulant hydrogen peroxide (80ml; 35% w/w) is a higher concentration to the chemical tested in the study.

Remove chemical toxicity in selecting Chronos UV-C High Level Disinfection for pelvic ultrasound examinations that is chemical-free and ultrafast, thus improving quality patient care.

While it is clear that UV-C HLD technology has many favourable characteristics for disinfection in IVF applications, it also removes other issues caused by chemicals:6-10

  • Respiratory problems

  • Anaphylaxis

  • Skin reactivity, irritation

  • Dermatitis Systemic antibody production

  • Chemical burns to staff and patients

  • All chemicals require a rinsing step, to remove disinfectant residue toxicity from the probe a crucial step that could be forgotten
