U.S., Dec. 27 -- ClinicalTrials.gov registry received information related to the study (NCT07305051) titled 'Study Of Ultrasound Windows For Measuring Inferior Vena Cava Changes Before Cardiac Surgery' on Nov. 17.
Brief Summary: This research study will compare two ultrasound methods for assessing the inferior vena cava (IVC), a major vein that reflects intravascular fluid status and cardiac function before and after surgery. The standard method uses a subcostal ultrasound view obtained below the breastbone, but this approach may be limited in patients with obesity, surgical dressings, or postoperative discomfort. An alternative approach, the transhepatic view, uses the liver as an acoustic window and may provide improved feasibility in th...
