Einfluss der NatriumhydrogencarbonatVorbehandlung auf die Endqualität der Reinigung im RDG.

BICARMed® is a pre-treatment method using a pressurized sodium bicarbonate jet. We evaluate here the benefit of BICARMed® to facilitate and improve the quality of the final cleaning and compare it to the pre-treatment by immersion. After use in the operating room, the instruments are randomly divided into 2 arms. Arm A: pre-treatment with detergent-disinfectant (n=539 instruments); Arm B: pre-treatment with BICARMed® (n=555 instruments). At the end of the pre-treatment, the instruments were cleaned in a washer-disinfector (WD) and the residual contamination after cleaning was visually assessed and evaluated by a semi-quantitative colorimetric method. The percentage of soiled instruments after cleaning in the WD was on average higher in arm A (44.7%; n=241) than in arm B (19.8%; n=110) (p-value < 0.001). Contaminated areas and color intensity were also higher in arm A. The effectiveness of the bicarbonate pre-treatment improves the quality of the final cleaning. [ABSTRACT FROM AUTHOR]
