Area of Science:

  • Microbiology
  • Infectious Disease Control
  • Hospital Hygiene

Background:

  • Disinfection is crucial for preventing healthcare-associated infections.
  • Evaluating the efficacy of commercially available disinfectants is essential for clinical practice.
  • Henkel Austria disinfectants were assessed for their microbicidal properties.

Purpose of the Study:

  • To verify the effectiveness of specific Henkel Austria disinfectants (Spitaderm, Incidin M spray, Incidur, Incidur spray, Sekusept pulver, Sekusept forte, Maranon H).
  • To propose their practical application in Czechoslovak healthcare settings.
  • To assess their performance in both laboratory (in vitro) and real-world clinical environments.

Main Methods:

  • In vitro testing using standard suspensive, suspensive micromethod, and carrier methods.
  • Inclusion of various microbial strains: gram-positive and gram-negative bacteria, B. subtilis spores, yeasts, and a model virus.
  • In-practice evaluation over 4 weeks in university hospital wards (internal medicine, surgery) and a hemodialysis center.
  • Regular sampling of surfaces, instruments, and staff hands to estimate bacterial contamination.
  • Specific assessment of artificial kidney apparatus disinfection with Maranon H.

Main Results:

  • Disinfectants demonstrated effectiveness at recommended concentrations and exposure times with a sufficient safety margin.
  • Significant reduction in bacterial contamination was observed in the clinical wards.
  • Positive user feedback regarding scent, cleaning properties, and precise dosage equipment.
  • All tested disinfectants met stringent requirements for modern, effective disinfection.

Conclusions:

  • The evaluated Henkel Austria disinfectants are highly effective for clinical use.
  • Their application can significantly minimize bacterial contamination in healthcare facilities.
  • Licensed production is recommended based on the positive experimental outcomes and user acceptance.
