Hemodynamic monitoring protocol using ultrasound in patients with acute renal failure

Introduction: in patients with acute renal failure, hemodynamic monitoring is essential. In this regard, ultrasound techniques are highly useful due to their safety and informational value, enabling timely diagnostic and therapeutic decisions.Objectives: develop a protocol for hemodynamic monitoring by ultrasound in patients with acute renal failure.Methods: a descriptive technological development research project was conducted. Theoretical, empirical, and statistical methods were used. It was developed in three phases: 1) theoretical argumentation phase, 2) protocol development phase, and 3) protocol evaluation phase. The research was conducted in accordance with the principles of medical ethics and was approved by an institutional Scientific Council.Results: a structured protocol was developed in the diagnostic sequence: lung ultrasound (LUS), assessment of systemic congestion (VExUS) and echocardiography (FoCUS).Conclusions: the protocolized use of ultrasound for hemodynamic monitoring is a noninvasive and valuable tool in the evaluation and management of acute renal failure, providing critical information on the anatomy and function of the kidneys and other related organs, allowing for better treatment guidance for this condition.
