Brief Summary

Cardiopulmonary bypass (CPB) is a critical technology in cardiac surgery, allowing for the temporary replacement of the heart and lung functions during intricate surgical procedures. it has significant post-surgical complications, the most important complications of CPB is right ventricle (RV) dysfunction. Diagnosis and management of RV dysfunction is crucial for maintenance of hemodynamic stability and organ function in early post-operation period and prognostic for later phase.

Keywords

Cardiopulmonary bypass (CPB) -Tricuspid annular plane systolic excursion (TAPSE)-Epinephrine - Milrinone

Outcome Measures

Primary Outcomes (1)

  • The incidence of change in Tricuspid annular plane systolic excursion (TAPSE) within 5 minutes post-cardiopulmonary Bypass from the basal value

    measured by Transesophageal echocardiography (TEE)

    Basal then within 5 mins post-cardiopulmonary bypass

Secondary Outcomes (5)

  • Tricuspid annular plane systolic excursion (TAPSE)

    within 30-60 minutes post-cardiopulmonary bypass

  • Incidence of Right Ventricular Dysfunction after Cardiac Surgery

    24 hours postoperative

  • Incidence of Arrhythmias

    intraoperatively and 24 hours postoperative

  • Vasoactive-Inotrope Score (VIS)

    recorded at 6, 12, 24, and 48 hours postoperative

  • Total consumption doses of Vasopressors

    48 hours postoperative

Study Arms (2)

Epinephrine group (group E)

ACTIVE COMPARATOR

The patients receive 0.05-0.1 mcg/kg/min.of epinephrine 5-10 minutes before aortic unclamping

Drug: Epinephrine

Milrinone group (group M)

ACTIVE COMPARATOR

patients will recieve an initial bolus dose of of 50 µg/kg, followed by 0.40 -0.80 µg/kg/min 5-10 minutes before aortic unclamping

Drug: Milrinone Injection

Interventions

Normal saline bolus over 10 min followed by Epinephrine intravenous infusion of 0.05-0.1 mcg/kg/min.of epinephrine 5-10 minutes before aortic unclamping

Epinephrine group (group E)

Milrinone initial bolus doses of 50 µg/kg, followed by 0.40 - 0.80 µg/kg/min of milrinone 5-10 minutes before aortic unclamping

Milrinone group (group M)
