Prehospital CPAP vs. Usual Care for Acute Respiratory Failure - Full Text View

Sponsor:	Dalhousie University
Collaborator:	Capital District Health Authority, Canada
Information provided by:	Dalhousie University
ClinicalTrials.gov Identifier:	NCT00405314

Purpose

The purpose of this study is to evaluate the effectiveness of continuous positive airway pressure ventilation when applied by paramedics to individuals with severe breathing difficulties in the prehospital setting.

Condition	Intervention
Respiratory Insufficiency Hypoxia	Device: Continuous positive airway pressure ventilation mask

Study Type:	Interventional
Study Design:	Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Single Group Assignment Masking: Open Label Primary Purpose: Treatment
Official Title:	Prehospital CPAP Versus Usual Care for Acute Respiratory Failure: a Randomized Controlled Trial

Further study details as provided by Dalhousie University:

Primary Outcome Measures:

proportion of patients in each group endotracheally intubated prior to hospital discharge or death

Secondary Outcome Measures:

mortality
critical care unit length of stay
hospital length of stay

Estimated Enrollment:	60
Study Start Date:	July 2002
Estimated Study Completion Date:	March 2006

Detailed Description:

Continuous positive airway pressure ventilation (CPAP) has been shown to be effective in avoiding endotracheal intubation (ETI) for patients with acute respiratory failure in hospital but despite several case series, the effectiveness of the prehospital application of CPAP by paramedics has not been studied in a randomized fashion. We performed a prospective, randomized, non blinded trial to determine whether patients in acute respiratory failure treated with CPAP in the prehospital setting had lower overall ETI rates than those treated with standard care.

Eligibility
