Assess the Ability of Electrical Cardiometry to Trend Hemodynamic Variables During Dexmedetomidine Sedation
This trial has been completed.
|Conditions||cardiac output, sedation|
|Sponsor||Boston Children’s Hospital|
|Start date||September 2009|
|End date||September 2011|
|Trial size||17 participants|
|Trial identifier||NCT01001533, 09-03-0130|
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.
All pediatric patients (1 month to 18 years of age) eligible for Radiology Sedation Service for CT scan and Nuclear Medicine Scan procedure.
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.
