Out-of-Hospital Non-Invasive Ventilation for Patients With Acute Respiratory Failure (NIV)

This study has been completed.

In the past, patients suffering from acute respiratory failure had to be treated with Oxygen and specific medication, or - if this had not been sufficient - had to be anesthesized and had to undergo endotracheal intubation for invasive ventilation. Nowadays, since emergency ventilators are available that can be used for non-invasive ventilation, the purpose of this study is to investigate if non-invasive ventilation is safe, feasible and effective for the treatment of acute respiratory failure and if less patients will need to be intubated out-of-hospital as well as in the further course.

Study Completion Date: April 2009
Primary Completion Date: January 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
"Non-invasive ventilation"
Procedure: Non-invasive-ventilation
increased oxygen fraction, continuous positive pressure ventilation, if necessary pressure support ventilation or even intermittent positive pressure ventilation
Active Comparator: 2
Procedure: conventional treatment
oxygen, diuretics, bronchodilators, positive inotropic drugs

Detailed Description:

Single center, prospective, randomized, intention-to-treat clinical trial. The study has been performed within a two tier EMS system of a major city. Prehospital emergency physicians are on scene in every patient enrolled to the study.

Patients with acute respiratory failure (SaO2 < 90%, respiratory rate > 20/min) were enrolled to the study using envelopes for randomisation for either "conventional" (O2 + medication) or "NIV." Vital signs have been documented as well as venous blood gases have been taken every 10 minutes after treatment has been started.

Primary endpoints are 28-day mortality, hospital-, ICU- and respirator-days, SAPS, SOFA II and complications. Secondary endpoints are out-of-hospital incidence of invasive ventilation, effect on SpO2, CO2, respiratory rate, heart rate and blood pressure.
