Introduction:
Hand hygiene is an important procedure in preventing peritoneal dialysis-related infections.
Objective:
To compare the effectiveness of two distinct techniques for hand hygiene in reducing the number of colony-forming units in patients on peritoneal dialysis.
Materials And Method:
Controlled clinical trial. Thirty patients underwent three collections of microbiological flora from the hands in three different instances: before and after hand washing with glycerin soap and water, and after rubbing 70% glycerin gel-alcohol. Cultures were obtained by applying the fingers surface directly on agar-blood plates.
Results:
Cultures mean growth were 31, 30 e 12 colony-forming units prior to washing, after washing with glycerin soap and water, and following gel-alcohol, respectively (p < 0.001). Staphylococcus epidermidis was the predominant germ in culture, occurring in 93.7% of seeded plates.
Conclusion:
Hand rubbing with gel-alcohol was more effective in reducing the number of colonies recovered than the other methods.

Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
