Abstract
Background: Tetralogy of Fallot represents 10% of all congenital heart defects and is the most common form of cyanotic heart disease. Aim of the Work: the aim of this work is to compare between effect of Milrinone and dobutamine as positive inotropic agent in separation from cardiopulmonary bypass in fallot tetralogy repaired by transannular patch technique. Patients and Methods: After approval of department of anesthesia, faculty of medicine, Ain Shams University, and the medical ethics committee, an informed consent was obtained from all patients’ guardian. This study was conducted on 150 pediatric patients of ASA III-IV, admitted to the cardiothoracic surgery unit, Ain Shams university hospital for elective fallot tetralogy total repair. Their age ranged from 12 to 24 months, weight from 6 to 15 kilograms and of both sexes. Results: the present study, regarding hemodynamics parameters; there were no significant changes in SBP between both groups, while DBP was higher in dobutamine group rather than milrinone group. Conclusion: Both inotropic support milrinone and dobutamine are effective in management of post cardiopulmonary bypass after Fallot repair by transannular patch as inotropic drugs. Recommendations: Further studies are needed to confirm the present study results.
