Acute kidney injury in patients with invasive mechanical ventilation in Guantanamo, 2018-2019

Abstract

Introduction: acute kidney injury is a very common complication in the intensive care units, especially in patients with invasive mechanical ventilation. Objective: to characterize acute kidney damage in patients with invasive mechanical ventilation in the intensive care unit at the General Teaching Hospital ¨Dr. Agostinho Neto¨ within the period 2018-2019. Method: a descriptive, retrospective and longitudinal study approved by the Ethics Committee was carried out. The study population was constituted by the total of patients with the diagnosis, according to the Acute Kidney Injury Network (AKIN). Characteristics and variables like: reason for the invasive mechanical ventilation, its duration, hemodialysis, and status of the patient at time of discharge were taken into account, along with the characteristics of the kidney injury (stages and etiology). Results: 47.5 % of the patients treated with life support showed acute kidney injury, especially the ones with more than a week of mechanical ventilation (68.4 %). The risk of death was higher in the patients with mechanical ventilation and hemodialysis. In the patients with stage 2 and 3 of the scale used for kidney injury presented 3 times more risk compared to those who did not require these treatments. Sepsis was the main cause of acute kidney injury (69.4 %). Conclusions: the use of invasive mechanical ventilation and acute kidney injury are deeply related to each other, both of them constitute main issues in the variables of mortality.
