Microbiological diagnosis of the infections at the Intensive Care Unit

Abstract

In a transversal, retrospective study of descriptive type, we analyze the behavior of the more frequently isolated microorganisms and their resistance to the antibiotics at the Intensive Care Unit of the Mario Muñoz Monroy Hospital of Matanzas, during 2004 and 2005. The laboratory diagnostic work was carried out by means of culture of different samples of the infected patients´ corporal fluids according to the branch norms of the specialty. To determine the resistance and susceptibility of the aisled germens we used the diffusion method in Mueller Hinton´ plates. The Enterobacter is the most frequently isolated germen among the cases of sepsis we studied, followed by Klebsiella and Citrobacter; Estafilococos epidermis and Hafuia are lest frequently. Tracheabronchial secretions were the samples with highest positiveness reached, predominating in them gram negative germs as a main cause of respiratory infections, and standing out Klebsiella. Kanamicina, Cefotaxima and Ceftriaxona are the antibiotics with higher resistance, while Amikacina and Imipenen are those with more sensibility to the isolated germs.
