Delayed Sternal Closure after Cardiac Operations for Congenital Heart Disease in Infancy / 日本心臓血管外科学会雑誌

ABSTRACT

Among 95 infants aged less than one year who underwent intracardiac repair for congenital heart disease at Kurume University Hospital between August 1990 and June 1995, a patients (3.9%) received primary elective open sternal (PEOS) and delayed sternal closure (DSC) after operation. 1) The mean interval for DSC was 4.3±0.9 (2-8) days, and DSC interval significantly correlated with the extracorporeal circulation (ECC) time. 2) Before DSC, patients became hemodynamically stable and requirements for inotropes and FiO₂ for mechanical ventilation decreased. 3) It was important to carefully manage fluid balance before DSC, and the balance after operation should be 0. 4) There was only one patient with mediastinal infection. Of the three patients who died in hospital the cause of death was pulmonary infection due to prolonged mechanical ventilation. 5) Both PEOS and DSC required careful postoperative management, but, the treatment seemed to improve postoperative results in cases in which postoperative hemodynamic status was unstable due to prolonged ECC.
