ABSTRACT

Introduction: hemodynamic management in critically ill patients focuses on maintaining optimal cardiac output and blood pressure. In the context of septic shock, vasopressors are used to achieve this. Renal perfusion is evaluated as a success parameter through diuresis and creatinine clearance, as variations in blood pressure directly impact perfusion once the autoregulation threshold is reached. The VeXus protocol uses Doppler ultrasound to classify venous congestion and predict acute kidney injury. Objective: to compare the baseline renal resistance index measured by ultrasonography upon admission to the intensive care unit (ICU) in patients diagnosed with sepsis and to assess changes in this index with the use of Norepinephrine. Material and methods: descriptive, longitudinal, prospective, single-center study evaluating variations in the renal resistance index using Norepinephrine. Results: in a sample of 42 patients, no significant changes were observed in the index of the dose of norepinephrine, with a correlation of 0.2369033. Conclusions: no changes were observed in the renal resistance index in patients requiring Norepinephrine during their ICU stay.
