Importância da presença de granulações tóxicas para o diagnóstico hematológico de septicemia

Abstract

This work aims at investigating the association of the presence of toxic granulation with positive blood cultures, age of patients, conditions of hospitalization and types of bacterial agents. Blind prospective and retrospective, analyses were carried out for the presence of toxic granulations-in blood samples of 300 patients of the both genders hospitalized in the City of Belém, Pará, Brazil. Request blood tests over a two year period were evaluated. The blood tests and cultures were performes using automated methods. All the data were statistically compared using the Qui-square test (clump method). The results show statistical associations between: (1) the presence of toxic granulations and positive blood cultures; (2) lower ages of patients (the newborn) and positive blood cultures; (3) hospitalization in the ICU and positive blood cultures and (4) toxic granulations-and the observation of leucocytosis and right-left shunts in patients hospitalized in the ICU with positive blood cultures. The commonest bacterial agents identified were klebsiella oxytoca (22%), Acinetobacter calcoaceticus (20%), Escherichia coli (18%), Enterobacter cloacae (14%), and Pseudomonas aeruginosa (8%).
