Fluid Responsiveness Assessment for Intensive Care Bed Patients

Abstract

Fluid administration in the ICU is essential, requiring an accurate assessment of the patient's intravascular status. Methods such as PLR can help in predicting hemodynamic response. Managing proper volume is crucial, as both insufficiency and excess can be detrimental, highlighting the importance of fluid responsiveness in fluid therapy guidance. The aim of this research is to analyze the importance of intravenous fluids in critically ill patients in ICUs, including the evaluation of the different types of fluids available and strategies for effective fluid therapy, with an emphasis on the prevention of fluid overload. This study consists of a literature review with a qualitative descriptive approach. The methodological framework of the bibliographic research was used to carry it out. The search for material took place in March 2024, in the databases of the Scientific Electronic Library Online (SciELO), Virtual Health Library (VHL) and National Library of Medicine (PubMed). The terms used were "Intensive Care Units", "Fluids" and "Hemodynamic monitoring", combined with the connective "AND". The selected studies will be read and analyzed, using the specialized literature to build dialogues and inferences on the subject, with the aim of strengthening the discussions. Infusions of dextrose in water with electrolytes are common in fasting patients to prevent electrolyte imbalances and hypoglycemia. To avoid complications such as water overload, appropriate management strategies are essential. During resuscitation, it is crucial to avoid excessive administration of fluids, while in the stabilization phase, administration should be restricted.
