Bedside Ultrasound for Fluid Estimation

Completed

• Conditions: Catheterization
• Interventions: Device: Ultrasound imaging

• Registration Number: NCT05159063
• Lead Sponsor: Gaurang Vaidya

Brief Summary

The study aims to standardize patient positioning during bedside ultrasound assessment of internal jugular vein (IJV) and correlate the results with invasive hemodynamics obtained immediately after. The study hypothesizes that the respiratory variation in the size of IJV, as estimated through ultrasound at bedside, is an accurate estimation of the patient's actual right atrial pressure estimated through right heart catheterization.

Primary Outcome Measures

Name	Time	Method
Cross-sectional diameters of the inferior vena cava (IVC)	5 minutes	Sniff collapsibility - Complete collapse (0cm) of the cross sectional diameter of IVC on sniff maneuver by the patient, as assessed by M-mode of the ultrasound.
Cross-sectional diameters of the internal jugular vein (IJV)	5 minutes	Diameter variation index will be calculated as: (maximum diameter - minimum diameter)/ body surface area.
Sniff collapsibility of IJV	10 minutes	Complete collapse (0cm) of the anteroposterior diameter of IJV on sniff maneuver by the patient, as assessed by M-mode on the ultrasound.
