Comparison of postoperative outcomes of milrinone versus dobutamine in tetralogy of Fallot with transannular patch

Abstract

Background: Since the original description of TOF, its management modalities are continuously evolving. Present modality includes complete correction of the pathology by intra-cardiac repair with or without using transannular patch. Various finer aspects of intraoperative and postoperative management of the TOF repair are still evolving. Aims and Objectives: In this single centre study we are aiming to compare short term outcomes in patients of tof operated with transannular patch repair treated postoperatively with dobutamine vs milrinone. Materials and Methods: Total 100 patients undergoing TOF repair with transannular patch were grouped with respect to the inotropes used. One group who received milrinone and other who received dobutamine. Postoperative outcomes depending upon the need of other inotropic support, duration of ventilatory support, icu stay , inotropic support , hospital stay , morbidity and mortality are compared between the groups. Observations: No significant difference was seen in both groups for mean ventilation time, duration of icu and hospital stay. Only parameter which was significant was increase in usage of adjuvant inotropic support in milrinone group which were depicted in terms of increased VIS ( Vasoactive inotrope score). Almost equal incidence of adverse events were noted in both the groups. Conclusion: Milrinone and dobutamine are fairly comparable to each other in cases of TOF repair with transannular patch. Dobutamine being a cheaper alternative have a better scope in developing countries like India.
