ABSTRACT
The present study evaluates the efficiency of the following decontaminating agents for the multiresistant, locally circulating bacterium Pseudomonas aeruginosa: glutaraldehyde 2
--makes A and B-, glutaraldehyde-formaldehyde; povidone-iodine-makes A, B and C-; sodium hypochloride; chloroxylenol--makes A and B-; and lapire chloride. The 9027 ATCC strain was used as a standard. A modification of the method of Kelsey and Sykes (1) was used to evaluate decontaminating efficiency. Highly satisfactory results were obtained with glutaraldehide 2
A and B, glutaraldehyde-formaldehyde and sodium hypochlorite. The results for povidone-iodine A, B and C were satisfactory but were unsatisfactory for chloroxylenol and lapirium chloride.
ABSTRACT
534 autoclaves from Rosario dentist offices were controlled by a method developed in our laboratory, that consists in: a) a procedures instruction; b) a survey ; c) a colorimetric control; d) a biological control. By this method it is possible to detect the mistake in the autoclave function by only one step. The results showed that 86.90
of the autoclaves lacked thermometers, 76.60
were automatic and 58.80
did not sterilize. It can be concluded the necessity of a periodic control by this method, the importance of a commercial quality control of the furnaces and the urgency of continuous education over biosafety concepts.
