Transhepatic Versus Subcostal Views to Assess Inferior Vena Cava Variation in Pediatric Patients

Not Applicable

Not yet recruiting

• Conditions: Inferior Vena Cava Abnormality
• Interventions: Diagnostic Test: Ultrasound Analysis of Inferior Vena Cavae (IVC)

• Registration Number: NCT04298216
• Lead Sponsor: Stanford University

Brief Summary

Currently, in order to visualize the inferior vena cava (IVC) of the heart using ultrasound, physicians traditionally place the ultrasound probe onto the "Subcostal" area which is located below the chest in the upper abdomen area. In this location, the pressure from the ultrasound probe is often uncomfortable for adults, and even more so for pediatric patients. Previous research and physician experience have demonstrated that it is possible to visualize the heart in the "transhepatic" area which is located under the arm on the side of the chest. By placing the ultrasound probe in this location, it is more comfortable for the patient when applying pressure, and this study aims to prove the effectiveness of visualizing the heart through this new location.

Arm && Interventions

Group	Intervention	Description
Assessment of Inferior Vena Cavae with Subcostal View	Ultrasound Analysis of Inferior Vena Cavae (IVC)	Patients will have a novel operator attempt to visualize their Inferior Vena Cavae with the probe placed in the subcostal region.
Assessment of Inferior Vena Cavae with Transhepatic View	Ultrasound Analysis of Inferior Vena Cavae (IVC)	Patients will have a novel operator attempt to visualize their Inferior Vena Cavae with the probe placed in the transhepatic region.

Primary Outcome Measures

Name	Time	Method
Accuracy of the IVC Analysis	For the entirety of the ultrasound procedure.	Novel Operators will be evaluated by the ultrasound expert who will confirm clinical success in locating the IVC.
Time	For the entirety of the ultrasound procedure.	Novel Operators will be timed from the point at which the probe is placed until the image has been and will be evaluated between both the control and experimental groups.
