PROCEDURE FOR APPLYING MEDICAL ASEPSIS
Hospital-acquired (nosocomial) infections and cross infections (infections that are
transmitted between individuals with different pathogens) show the need of applying
basic principles of medical asepsis. The following steps outline the basic procedures
used in applying medical asepsis.
a. Perform Patient Care Handwash. Follow previous instruction on patient
care handwash. The patient care handwash is the most important step in preventing
and controlling infection. There may be times when you do not have the materials or
the time to do a thorough handwash; however, always wash your hands and clean your
fingernails if time permits.
b. Disinfect Materials as Required. Disinfecting means cleaning objects to
remove most organisms. Follow directions explicitly where chemical agents are used.
c. Maintain Clean Patient Care Environment.
(1) Concurrent cleaning. Disinfect and dispose of infectious matter
immediately during the course of a disease. This is a constant task.

transfers, or is discharged.

furniture, mattress covers, grossly soiled areas of walls, and equipment not handled by
Wet-vacuum or mop floors.
