ABSTRACT

Introduction. Nosocomial infections in patients undergoing surgical procedures may be associated with inadequate or poor hand hygiene, because microorganisms with very different virulence factors may be causing infectious diseases. The aim of this study is to analyze the proportion of microbial load reduction after hand washing procedure of the staff at the operating room area of the General Area Number 2 Hospital of the IMSS, in San Luis Potosí, México, and to carry out identification of microbiological isolates.
Materials and methods. Descriptive study in which the studied population included staff from the health team, who participated in surgeries scheduled in the two operation rooms of the institution, and agreed to participate in the study from October to November 2009.
Results. Specimens with an initial quantification› 1x10⁶, which struck in at least 90% were 71.43% (20) p ‹0.05. Coagulase-negative Staphylococcus, and Bacillus sp were the microorganisms most frequently isolated, followed by S. aureus, non lactose-fermenting Gram-Negative rods (Stenotrophomonas, Acinetobacter and others), and enterobacteria.
Conclusions. This study found that, in general, 71.43% of staff had a decrease of at least 90%, mainly in the group with initial count greater than, or equal to, 1X106 CFU. This can imply that the procedure is performed properly.
