Hyoung Won Lee, You In Park, Kwang Chul Lee, Ju Won Lee, Soon Kyum Kim
Clin Exp Pediatr. 1992;35(1):34-43.   Published online January 15, 1992
Despite the scientific advances made in medical science, the potential for serious hemorrhagic complications remain an important problem in patients undergoing open heart surgery with extracorporeal circultation (OHSEC). Hematologic abnormalities that have been reported in association with OHSEC and that may lead to a hemorrhagic tendency include thrombocytopenia, alteration of coagulation factors, advanced fibrinolysis and inadequate neutralization of heparin. We investigated...

The short-term effects of increasing hemoglobin concentration were evaluated on cardiac catheter- ization in nine patients with congenital heart diseases and relative anemia. Diagnosis were ventricular septal defect in six, tetralogy of Fallot in two, and endocardial cushion defect in one. Various hemodynamic data including pulmonary and systemic blood flow, pulmonary and systemic vascular resistance and the degree of shunt were compared before and...
Left Ventricular Cardiac Output in Term Newborn Infants: Changes Associated with Closure of Ductus Arteriosus.
Ho Jin Oh, You In Park, Chang Sung Son, Young Chang Tokgo, Pyung Hwa Choe
Clin Exp Pediatr. 1989;32(8):1045-1050.   Published online August 31, 1989
We studied on leftventricular Cardiac output on the 25 normal newborn infants by using pulse Doppler echocardiography, before & after closure of ductus arteriosus, we also made closing time of ductus arteriousus by using pulsed & color Doppler echocardiography. The results were as follows; 1) The closure of ductus arteriosus was noted before 24hr of age in 3 cases (12%), 48hr of age in 19 cases...
