  Purpose
To assess whether a non-invasive cardiac output monitor can follow heart function in children during treatments in the hospital. To establish a normal reference for children who are well and awake.

Condition
Cardiac Output Blood Pressure

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Pilot Study: Cardiac Function as Measured by Non-invasive Electrical Velocimetry Cardiac Monitor in Hospitalized Children From Acute Illness (Disease) to Recovery (Health).

Further study details as provided by Jackson Wong, Boston Children's Hospital:

Primary Outcome Measures:
  • To document trends in cardiac output (CO) and systemic vascular resistance (SVR) in subjects undergoing systematic changes in mean arterial pressure (MAP) and to assess intra-individual variability for those with normal blood pressure [ Time Frame: During hospitalization until discharge ]

Secondary Outcome Measures:
  • To establish age relevant hemodynamic norms as measured by the electrical velocimetry (EV) cardiac monitor for trend parameters [ Time Frame: Measurements obtain on day of discharge ]

Enrollment: 83
Study Start Date: December 2009
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts
Elevated Mean Arterial Blood Pressure
Mean arterial pressure greater than 1 standard deviation above the mean based on age
Decrease Mean Arterial Blood Pressure
Mean arterial pressure greater than 1 standard deviation below the mean based on age
Normal Mean Arterial Blood Pressure
Mean arterial pressure within the standard deviation of the mean based on age

Detailed Description:
The aim of the study is to evaluate the ability of a new FDA-approved non-invasive Electrical Velocimetry (EV) cardiac monitor called AESCULON (Cardiotronic Inc, La Jolla CA) to detect and trend hemodynamic changes in hospitalized ambulatory pediatric patients during recovery from acute illness. We postulate that if the cardiac monitor can trend hemodynamic changes in hypertensive patients whose mean arterial pressure (MAP) decreases to normal levels, or hypotensive patients whose MAP increases to normal levels over several days, it may improve our understanding of different disease processes and allow us to improve care. We also seek to establish normative data for different measures provided by the AESCULON monitor - specifically cardiac output (CO) and systemic vascular resistance (SVR), which are the prime determinants of MAP.
