Abstract
Introduction: Congenital heart diseases (CHD) represent the most frequent group of congenital
disorders, with an incidence of 8 to 10 per 1000 live births. The aim of this study was assess the correlation
between the presence of CHD and the acid base status of the umbilical cord blood at the Fundación Cardiovascular de
Colombia during the period 2007-2018. Materials And Methods: Retrospective descriptive study in FCV, prior to authorization
of the ethics committee, medical records were reviewed and with ICD10 codes the patients with CHD were identied everyone
with prenatal echocardiography, CHD incompatible with life or incomplete records were excluded, It took a sample of arterial
blood from the umbilical cord, the sample was processed in a gases machine (i-STAT300F), the data was collected in Excel, the
heart diseases were classied according to the cardiopathophysiological classication, the association measure was -X2
Results: we met 111 patients with CHD, 56.7% men, in total 367 specic defects, grouped into 4 groups (IPB, DBPF, OBNSD and
NSBC) with 157, 50, 77 and 58 respectively. The pH, HCO3, Pco2, Po2 in general without alterations. However, when we compare
DPBF, it had an increase in the incidence of acidosis and mortality statistically signicant p = 0.005. Conclusions: according to
the ndings, we can afrm that there are specic heart diseases such as DPBF, which predispose worse results, including
acidosis and perinatal asphyxia. It also means that the changes in acid-base state in patients with CHD are not simply
physiological variations, but are indicators of pathology and mortality, just as in patients without CHD.
