Acute kidney injury in patients admitted to the intensive care unit of a general hospital

Abstract

Background: acute kidney injury is frequent in patients admitted to intensive care units. Despite being a potentially reversible phenomenon, high mortality rates are reported.Objective: to characterize clinical and epidemiological variables in patients with acute kidney injury admitted to the intensive care unit of the “Dr. Ernesto Guevara de la Serna” of the province of Las Tunas, from January to June 2020.Methods: an analytical, retrospective, case-control study was carried out with 60 patients older than 18 years with acute kidney injury, at the aforementioned institution and during the period herein declared. Two groups of 30 patients each were formed, according to vital status at ten days. The following variables were studied: age and sex, personal medical history, development of sepsis during admission, creatinine levels, glomerular filtration rate and urea.Results: the mean age was 52,57 ± 15,03 years and 68,33 % were male. There were differences between both groups in terms of previous chronic kidney disease and sepsis, as well as in creatinine, glomerular filtration rate and urea, always worse in the deceased. The prerrenal cause predominated (71,67 %). The highest incidence of deaths occurred at the third and eighth days of follow-up.Conclusions: patients with acute kidney injury were characterized in an intensive care unit. Previous chronic kidney disease, sepsis, and creatinine levels were variables with different incidence in the groups studied.
