Protocol summary

Study aim
Determining and comparing the effect of two drug regimens noradrenaline plus Milrinone versus noradrenaliene plus dobutamine`s effect on adult`s pulmonary hypertension after heart valve implantation.
Design
Clinical trial, consisting of two parallel groups receiving two different drug regimens, triple blinded, sample size of 38 patients, phase 3, randomized using random allocation software
Settings and conduct
In this study,38 patients suffering pulmonary hypertension who are candidates for heart valve replacement surgery in isfahan Shahid Chamran Heart hospital are randomly divided into two groups receiving milrinone + noradrenaline (group 1) and dobutamine + noradrenaline (group 2) using random allocation software. Systolic pulmonary arterial pressure (SPAP), Mean pulmonary arterial pressure (MPAP) and diastolic pulmonary arterial pressure (DPAP) are determined using echocardiography before surgery, then by implanting a pulmonary artery catheter، the above parameters are measured and recorded at the times after induction of anesthesia before Cardiopulmonary Bypass (CPB), after CPB, time to enter the Intensive care units(ICU) ،every 6 hours till 24 hours in the ICU and furthermore other parameters at the specific times.
Participants/Inclusion and exclusion criteria
Patients who are candidate for heart valve transplantation and suffering pulmonary hypertension The age over 18 years old The consent of patient to being involved ; Renal and hepatic failure Emergent surgery necessity to inotropic drugs before surgery Long QT interval patients Drug allergy
Intervention groups
The group that receiving noradrenaline with milrinone and the group that receiving noradrenaline with dobutamine
Main outcome variables
Reduction of pulmonary hypertension, reduction of mechanical respiration, reduction of inotropic drug using duration, reduction of ICU hospitalization, reduction of tachycardia

Randomization (investigator's opinion)
Randomized
Randomization description
This study is a randomized controlled clinical trial .before sampling, the order of assigning individuals to groups is determined randomly with random allocation software.In this way, before starting the sampling, patients are divided into two groups based on the Sequential turn number and as soon as they enter the study, they are assigned to one of the groups based on their turn number. In fact, patients are coded based on their turn number in the study and each code is randomly assigned to one of the groups. Individuals are assigned to groups by an operating room technologist outside the research team. The groups are marked with codes A and B and the researcher does not know the allocation of codes. Patients and the analyzer are also unaware of the medication received and the Drugs are blinded with names A and B. The group codes are opened after the analysis.
Blinding (investigator's opinion)
Triple blinded
Blinding description
Patients, clinical caregivers, outcome assessors, and data analyst are unaware of the medication regimen used in each patient group. In this way, the patients and drug regimens are divided into two groups A and B before entering the study and each patient receives the desired medication regimen according to that, which are blinded with the names A and B. The group codes are opened after the analysis.

Intervention groups

1

Description
Intervention group 1:The group that receiving Intravenous infusion of noradrenaline at a dose of 0.1 - 0.5 μg / kg / min with milrinone at a dose of 0.5 - 0.75 μg / kg / min. Medication regimens commence from the time of patient`s rewarming and continue until the patient's condition stabilizes in the Intensive Care Unit under the anesthesia attending`s care .Milrinone is a phosphodiesterase III inhibitor commonly used after cardiopulmonary bypass in combination with adrenaline or noradrenaline to reduce pulmonary artery pressure with a synergistic inotropic effect. Noradrenaline made by BCWORLD PHARM CO. South Korea and Milrinon made by Baxter India.

2

Description
Intervention group 2: The groupe that receiving Intravenous infusion of noradrenaline 0.1-0.5 μg / kg / min with dobutamine 5-10 μg / kg / min. Dubotamine through strong agonist stimulation effect on Bradykinin 1 Receptor and moderate stimulation effect on Bradykinin 2 Receptor increases myocardial contractility and increases stroke volume, cardiac output and heart rate and decreases vascular resistance. After cardiac surgery, the combined use of dobutamine with Noradrenaline has a double inotropic effect due to its competitive effect on Bradykinin 1 Receptor. Noradrenaline made by BCWORLD PHARM CO. South Korea and Dobutamine made by Darou Paksh- Iran.
