Assess the Ability of Electrical Cardiometry to Trend Hemodynamic Variables During Dexmedetomidine Sedation (DEX-CO)

January 4, 2017 updated by: Jackson Wong, Boston Children's Hospital

A Pilot Study to Assess the Ability of Non-invasive Bio-impedance Cardiac Monitoring to Detect and Trend Hemodynamic Variables During Dexmedetomidine (DEX) Sedation in Children for Radiology Procedures

The aim of the study is to investigate the use of a new FDA-approved non-invasive bio-impedance cardiac monitor, ICON, to detect hemodynamic effects during sedation in children undergoing radiology procedures. The purpose of the study is to determine the ability of the ICON monitor to identify the anticipated and documented hemodynamic changes in children which occur in response to Dexmedetomidine sedation. The investigators postulate that if the ICON device can trend hemodynamic changes, if any, during dexmedetomidine (DEX) sedation in children the investigators can delineate changes in cardiac output, stroke volume, and systemic vascular resistance associated with observed changes in heart rate and blood pressure.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
The primary aim is to ascertain if a decrease in heart rate (HR) with intravenous (IV) DEX is associated with a change in trend of cardiac output (CO) as measured by the ICON device.
Time Frame: pre-, during, and post sedation
pre-, during, and post sedation

Secondary Outcome Measures

Outcome Measure
Time Frame
To determine the cardiac parameters provided by the ICON device during changes in blood pressure.
Time Frame: pre-, during and post sedation
pre-, during and post sedation
