Background:
Many publications have emphasized the need of proper cleaning, disinfection and sterilization process for reused materials intended to prevent cross infections. As the endoscope the esophageal manometry catheters are considered as semicritical materials and must be free of microrganisms.
Aim:
To standardize the esophageal manometry materials cleaning and disinfection process to guarantee the safety of patients when reusing semicritical materials. It was based on international protocols and according to recommendations of the Hospital Infection Control Commission of the "Hospital de Clinicas de Porto Alegre", Porto Alegre, RS, Brazil.
Materials And Methods:
Enzymatic detergent was used for catheter cleaning, followed by immersion with 2% glutaraldehyde solution during 20 minutes for high-level disinfection. The water reservatory was kept clean and dry to prevent microorganisms proliferation.
Conclusions:
The high level disinfection with 2% glutaraldehyde, preceded by enzymatic detergent cleaning, is a safe and simple technique that avoids cross infection in the esophageal manometry equipment. This care must be taken after each manometric procedure. The transducers must be resterilized in ethylene oxide. The professionals of this area must work in concordance with the Hospital Infection Control Commission, being acquainted with the country laws and regulations and keeping sterilizing process and materials updated.
