Background:

the infectious processes are one of the main causes of morbidity and mortality in the burned patients, which is why the early diagnosis of the infection through the bacteriological quantitative study represents a forward-motion step for the opportune treatment of these patients.

Objective:

to determine the diagnosis of infection in the burned patients by means of the bacteriological quantitative study of the injury by burn.

Methods:

a descriptive, cross-section study was carried out to determine by means of the bacteriological quantitative study of the injury by burn the diagnosis of infection in the burned patients entered in the service of Burn at Manuel Ascunce Domenech Universitary Hospital of the province Camagüey, from September 2015 to November 2017. 34 patients were studied in those who were evaluated the following variables: age, sex, severity rate, positivity or no of the qualitative and quantitative study relating to the clinical public demonstrations of infection.

Results:

in this study the feminine sex became represented by 70.59 %, predominating ages between 48- 67 years, the 38.23 % of injured persons were classified as very grave, and colonization was the predominant on the infection in the quantitative cultivation with a 26.47 %. In patients with clinical demonstrations of infection, the quantitative culture was positive in 11 of them for a 32.35 %. It was found in 44.12 % of patients, the presence from germs to a concentration of over 105 germen per gram of fabric.

Conclusions:

determining factors in the appearing of infection in the injury by burn were age, extension and depth of the injuries. There was a correlation between the positivity of the bacteriological quantitative study and the presence of clinical demonstrations of infection in these patients. Greater number of quantitative cultivations with positive results and their correlation with the presence of germs in the qualitative cultivations were documented.
