  Purpose
Pulmonary hypertension is an important morbidity factor in patients having to undergo cardiac surgery with cardiopulmonary bypass (ECC). Milrinone used in inhalation, shows evidence of being a pulmonary vasodilator able to possibly contribute to the reduction of pressure on the pulmonary artery.

Condition Intervention Phase
Valvular Stenosis Valvular Insufficiency Hypertension, Pulmonary Coronary Artery Disease Drug: Milrinone Drug: Normal saline Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: 2- Inhaled Milrinone Prevents the Increase in Pulmonary Artery Pressure After CPB

Further study details as provided by Andre Denault, Montreal Heart Institute:

Primary Outcome Measures:
  • To demonstrate that inhaled milrinone administered before CPB is superior to placebo in reducing the severity of difficult separation from bypass [ Time Frame: End of CPB ]

Secondary Outcome Measures:
  • Reduction in morbidity and mortality post-op [ Time Frame: At discharge, 3 months, 6 months and 1 year by telephone ]
  • Reduction in pulmonary artery pressure [ Time Frame: Same day before and after CPB ]
  • Right ventricular function measured using transthoracic echocardiography (TTE) and TEE [ Time Frame: Same day before and after the CPB ]
  • Serum levels of milrinone in relation with the pharmacodynamic marker [ Time Frame: Same day pre CPB per CPB and post CPB ]
  • reduction of the composite index of hemodynamic complications (defined as hospital death, vasoactive drugs > 24 hours and post-op cardiac arrest), [ Time Frame: 24 hrs post op and hospital discharge ]

Estimated Enrollment: 124
Study Start Date: February 2009
Study Completion Date: December 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Normal saline

Drug: Normal saline
5 ml normal saline by inhalation over 15 min
Other Names:
  • Placebo
  • Comparator
Active Comparator: Milrinone
Inhaled milrinone 5 mg(as for the injectable solution)
Drug: Milrinone
inhaled milrinone 5 mg (as for the injectable solution)
Other Names:
  • Milrinone Cardiac Surgery
  • Milrinone inhaled
  • Inhaled milrinone reduces pulmonary artery pressure

Detailed Description:
This controlled, randomized, double-blind study will aim at confirming the efficiency as well as the security of Milrinone, used in inhalation, to diminish the degree of pulmonary hypertension before the cardiopulmonary bypass (ECC) circulation. In addition, the pharmacokinetic and echo graphic repercussions of administering the medication will be analysed. At the present time, there is no data on the pharmacokinetics of the medication when it's administered through inhalation. For this reason, we would like to study the serous rate of the medication in the minutes following its administration through inhalation.
