About this study
Official title: Assessments of Early Hemodynamics in Emergency Department Patients and Evaluation of Trends and Variability in Prediction of Life-saving Interventions
This study is an observational prospective pilot trial that utilizes finger cuff non invasive hemodynamic monitoring (NexfinHD Monitor) to assess 4 different groups (CHF/COPD, Trauma, Sepsis, Stroke) of patients on arrival to the Emergency Department and to document the changes seen in these hemodynamics with acute therapies.
Read the detailed description
There has been little very early (after Emergency Department presentation) hemodynamic monitoring of acutely ill or injured patients secondary to the lack of non invasive technologies that could be reliably applied to this patient population.Thus all assessments of hemodynamics have been made by physicians on clinical information including intermittent pulse and blood pressure measurements. It is not known what the underlying continuous cardiac output, systemic vascular resistance, etc are in these patients and how these change with current Emergency Medicine therapeutic interventions. Currently there is available a finger cuff devise (NexfinHD Monitor, BMEYE, Amsterdam) that can measure these hemodynamics on a beat to beat basis and that can be easily applied to acutely ill individuals. This prospective pilot study of 48 patients (4 groups of 12 each) will document the hemodynamics of patients on arrival and continuously for 2 hours, blinded to the treating physician. Treating physicians will be asked to estimate these hemodynamic parameters at various time points. The study will characterize the hemodynamics of patients, compare them to the estimates of treating physicians and determine whether they predict the need for life saving interventions.

Measured: ED arrival to 2 hours
To calculate short term hemodynamic variability parameters and their prediction of life saving interventions within 2 hours and subjective/objective estimation of clinical improvement

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00851214, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Feb 2010.
