Correlation of inferior vena cava ultrasound with packed cell volume and clinical condition in children with dengue fever

Objective: to correlate collapsibility of the inferior vena cava (ivc) with packed cell volume (pcv) and clinical condition and to ascertain ivc collapsibility as a guide to estimate intravascular volume using bedside ultrasonography (usg) in children with dengue fever. methods: a prospective observational study was conducted in the pediatric emergency department of an academic hospital in india. clinical data and pcv of children with dengue fever aged between 1 month to 18 years were documented. the collapsibility of ivc was determined using bedside ultrasonogram. results: ivc collapsibility correlates with high pcv and dengue shock in children ( p = 0.000). ivc was not collapsible in children with normal pcv ( p = 0.000). the collapsibility of ivc correlated with the need for normal saline bolus ( p = 0.000),colloids ( p = 0.002),picu admission ( p = 0.015) and mortality ( p <,0.05). conclusions: the assessment of intravascular volume status by determining ivc collapsibility using bedside usg is a helpful non-invasive tool in children with dengue fever. © 2016 raman,licensee hbku press.
