The purpose of this study is to investigate the concentration-effect relationship of inhaled milrinone after prophylactic administration in cardiac surgical patients with preoperative pulmonary hypertension undergoing cardiopulmonary bypass.

Condition Intervention Phase
Pulmonary Hypertension
Drug: Inhaled milrinone 5 mg

Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Pharmacokinetic and Pharmacodynamic of Inhaled Milrinone in Cardiac Surgical Patients

Further study details as provided by Montreal Heart Institute:

Primary Outcome Measures:
  • Study the elimination rate of milrinone administered by inhalation [ Time Frame: up to 24 hours ]

Secondary Outcome Measures:
  • Demonstrate the presence or absence of hemodynamic and echographic effects observed after inhalation of milrinone [ Time Frame: 15 min after the of study drug administration ]
    hemodynamic values evaluated will be: central venous pressure, systolic and diastolic pulmonary pressure, wedge, cardiac output, cardiac frequency, systolic and diastolic pressure, SaO2, EtCO2. Patient will also have arterial and venous gaz. Echographic values will be evaluated to see the cardiac fonction: left and right ventricular systolic and diastolic function and valvular function.

  • Confirmation of the safety of inhaled milrinone [ Time Frame: 24 hours after cardiac surgery ]
    Verification of the absence of deleterious effects on cardiac output and systemic arterial pressure.

  • Determination of the efficacy of inhaled milrinone in the treatment of pulmonary hypertension [ Time Frame: 15 min after end of milrinone administration ]
    Efficacy in the treatment of pulmonary hypertension is defined as a reduction of the mean pulmonary pressure of 10-20 %
