New disinfectants.

Abstract

The authors estimated the microbicidal effect of disinfectants produced by the firm Henkel Austria, namely Spitaderm, Incidin M spray, Incidur, Incidur spray, Sekusept pulver, Sekusept forte and Maranon H. The aim of the study was the verification of the effectivity of preparations and the proposal of their application in Czechoslovak practice. The estimation was performed in two stages: in vitro and in practice. The standard suspensive method, the suspensive micromethod and the method of carriers were chosen for the experiments, as well as the strains of grampositive and gramnegative bacteria, the spores of B. subtilis, yeasts and the model virus. In the second part of experiments, the disinfectants were applied according to the producer's instructions in inpatient departments of internal medicine and of surgery at the University Hospital in Olomouc in the course of 4 weeks. During the experiment, the rubdowns were taken twice a week from the working places, floor, instruments and hands and the bacterial contamination of the establishment was estimated. In hemodialysing centre, the apparatuses of the artificial kidney were estimated as well, as the preparation Maranon H is recommended for their disinfection. The results of the experiments show that the recommended concentrations of disinfectants and their effective exposition are chosen with sufficient safety coefficient. In chosen wards, the minimum bacterial contamination was observed. All disinfectants were accepted favourably, their scent estimated as pleasant, the staffs evaluated their high cleaning properties and the dosage equipment, ensuring the precise concentration of preparations. With regard to the above mentioned results, the authors recommend to start the licensed production, as all the tested preparations correspond to the exigent demands of modern and effective disinfection.
