Clinical Trial: Internal Jugular Vein Respiratory Variability as a Marker of Disease Severity in Infant Bronchiolitis

U.S., Aug. 22 -- ClinicalTrials.gov registry received information related to the study (NCT07778225) titled 'Internal Jugular Vein Respiratory Variability as a Marker of Disease Severity in Infant Bronchiolitis' on Aug. 15.

Brief Summary: This prospective observational cohort study evaluates whether respiratory-cycle variation in internal jugular vein (IJV) diameter, measured by point-of-care ultrasound, correlates with clinical disease severity in infants 1-23 months of age presenting with acute bronchiolitis. Using a standardized M-mode protocol, the IJV Variability Index ([IJVmax-IJVmin]/IJVmax x 100) will be calculated and compared with the Wang Bronchiolitis Severity Score, four additional validated clinical severity instruments (Modi...
