[Occupational exposure to glutaraldehyde during its use in chemical disinfection of endoscopes]
Background:
To evaluate the air pollution experimentally produced by different solutions of glutaraldehyde due to the activity of chemical disinfection in a flexible endoscopy unit.
Methods:
The glutaraldehyde environment concentrations due to the use of 3 solutions (2% solution and its 1:5 and 1:20 dilutions) were measured by liquid chromatography after sampling on specific cartridges and by fotoacoustic method.
Results:
Only after the use of the most concentrated solution it was possible to detect glutaraldehyde in the environment air, with values between 0.2 and 0.3 mg/m3 and during specific activities such as after shaking the disinfecting solutions.
Conclusions:
When the usual preventive recommendations are respected, the use of 1:5 and 1:20 solution of 2% glutaraldehyde products does not produce air concentrations of the aldehyde exceeding the current, even restrictive, limits proposed by industrial hygienists.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
