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

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.

Treatment and study plan

Ultrasound Analysis of Inferior Vena Cavae (IVC)

Diagnostic Test

Novel Operators will attempt to visualize the Inferior Vena Cavae through two different views on the patient's body. The images taken will be interpreted by an expert ultrasound user to determine if the novel operator was successful in locating and evaluating the IVC.

Primary outcomes

  1. Time

    Time frame: 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.

  2. Accuracy of the IVC Analysis

    Time frame: 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.
