HAND WASHING AND ASEPSIS

Thursday, October 28, 2010

Asepsis is commonly defined as the absence of pathogenic organisms. Hand washing is a proven method of asepsis, which effectively minimizes the onset and spread of infection. It is the brief but vigorous rubbing together of all the hands’ surface lathered with soap or antibacterial hand washing agents, followed by a thorough rinsing in a continuous stream of water.

The purpose of this procedure is to remove dirt and any transient organisms from the hands and the reduction of microorganism count.

Hand contamination is the most common cause of cross infection; and disease can be easily communicated from one person to another through hand contact or touching objects which have been contaminated. If a nurse fails to wash hands after handling articles, which are contaminated, he/she is most likely to spread infections.

Factors influencing Frequency of Hand Washing
• Intensity of contact with patients
• Patient/nurse’s susceptibility to infection
• Contamination degree that could result from contact
• Procedure/activity to be performed

Situations where Hand Washing is necessary
• When hands are visibly soiled
• Before and after contact with patient
• Before performing invasive procedures (e.g., intravascular catheter/indwelling catheter insertion)
• After contact with a source of microorganism (e.g., blood/bloody fluids, mucous membrane or potentially contaminated objects)
• After removal of gloves
