Evaluación de los factores y microorganismos más frecuentes en la contaminación de hemocultivos en hospitales

Abstract

The blood culture is a laboratory test of the utmost importance and one of the most effective when identifying the type of pathogen that affects the organism and health of the living being, but sometimes they can be altered by external agents causing contamination and altering the results , the objective of the present work is to evaluate the factors and microorganisms present in the contamination of blood cultures in hospitals, as well as the percentage rate of contamination established by international standards, the methodology applied to reach our objective was descriptive since it has been carried out investigations of different updated scientific articles obtaining important information to solve the unknown posed by means of the description of the information found in them, finished the work it was possible to identify bacteria such as negative coagulase staphylococcus, viridans streptococcus, spp bacillus, such as mi most common croorganisms found in contaminated blood cultures in addition to the factors that involve contamination such as asepsis at the time of taking the sample, the volume of blood to be analyzed and the correct processing of the sample respectively and the percentage of contamination allowed by the American Society Microbiology which are between 2% and 3% of the total samples analyzed. In addition, a proposal was made to reduce the errors that cause contamination at the time of performing a blood culture
