Continuous Positive Airway Pressure for Acute Pulmonary Edema (CPAP)

This study has been completed.

Assistance Publique - Hôpitaux de Paris Identifier:
First received: November 6, 2007
Last updated: March 29, 2010
Last verified: March 2010
The investigators hypothesise that CPAP + pharmaceutical treatment, compared to pharmaceutical treatment alone, improves the respiratory and hemodynamic status of the patients before H2 after the inclusion time and decreases the rate of death and tracheal intubation during the first 48 hours.

Condition Intervention Phase
Pulmonary Edema Dyspnea Paroxysmal Congestive Heart Failure Procedure: Continuous Positive Airway Pressure (CPAP) Procedure: usual care of acute pulmonary oedema Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Effect of Continuous Positive Airway Pressure on Short Term Inhospital Prognosis for Acute Pulmonary Edema

Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • Composite criteria includes during the first 48 hours : death, tracheal intubation and mechanical ventilation rates, persistence of inclusion criteria for respiratory distress and shock until H2, reappearance of inclusion criteria after H2. [ Time Frame: 48 hours ]

Secondary Outcome Measures:
  • brain natriuretic factor value curves from H0, H6 and H24; composite criteria without intubation rate; clinical and biological parameters evolution during the first 48 hours, myocardial infarction rate, CPAP non tol [ Time Frame: H0, H6, H24, H48 ]

Enrollment: 208
Study Start Date: October 2004
Study Completion Date: July 2008
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: A
Usual care of pulmonary acute oedema
Procedure: usual care of acute pulmonary oedema

Usual treatment of acute pulmonary oedema including :

Oxygen, diuretic minimum one bolus IV of 40 mg FUROSEMIDE (LASILIX) possibility to repeat the dose every 15 minutes with a maximum 120 mg.

Bolus of ISOSORBIDE DINITRATE (RISORDAN) of 1 mg maybe repeated every 3 minutes.

As soon as possible perfusion of ISDN with flow adapted to the clinical status If necessary administration of DOBUTAMINE continuous perfusion of to 5 to 20 µg/kg/min.

Experimental: B
CPAP + usual care of pulmonary acute oedema
Procedure: Continuous Positive Airway Pressure (CPAP)

Usual treatment of acute pulmonary oedema (see arm A) + CPAP will be administered without interruption for at least one hour and will be stopped for efficacy:

stade I or II KILLIP classification and FR less or equal to 25 /min and SpO2 larger than 90 % ambient air and patient willing the stop of CPAP because of improvement of his clinical status.

Detailed Description:
Patients are included at home after informed consent by the emergency medical team and transported during the following 2 hours to a cardiac intensive care unit were the treatment is purchased as well. Randomization process has been done previously with envelopes ; group A : pharmaceutical treatment alone , B pharmaceutical plus CPAP. Medical treatment includes furosemide and nitroglycerin (continuous perfusion and bolus), inotropes if needed, and all other specific treatment required (ex : anti antiarrhythmic drugs). Doses are free, adapted to the clinical response for respiratory and hemodynamic distress. CPAP is a passive high flow venturi system device alimented by a hyperbaric oxygen. FiO2 can be controlled and adapted to the pulsed oxygen saturation. PEP must be initially celled at least at 7.5 cmH2O and increased to 10 if well tolerated.
