Introduction: Evaluation of intravascular volume status in critically sick patients at the bedside. The risk of organ failure and death may be impacted by how fluids are managed, which in turn affects systemic perfusion. When formulating a fluid management plan, clinicians often employ data from invasive hemodynamic monitoring in addition to that obtained from a patient's physical examination and laboratory assessment. The central venous pressure (CVP) is a widely used hemodynamic measure. Ultrasound is a non-invasive and cost-effective method that may aid in the diagnosis and treatment of critically sick patients in the intensive care unit.

Aim of the work

The purpose of this research is to determine how fluid delivery affects IVC and common carotid artery (CCA) diameters, which are used to predict volume status in patients who are critically sick.



Patients and Methods:



After receiving clearance from the university ethics committee (approval number.133:2021) and the written informed consent of all Patients or first degree relatives, this prospective observational research was carried out between March 2021 and August 2022 at El-Minia University Hospital. We analysed 55 patients between the ages of 20 and 60, both sexes, who were admitted to our surgical Intensive care unit (SICU) with American Society of Anesthesiology (ASA) physical status II or III, were able to breathe on their own, were lying supine, and had a central venous catheter (CVC) placed because they needed constant monitoring and assessment of their intravascular volume status.
