[Monitoring of cardiac rhythm changes during surgical operations with total cardiopulmonary bypass with haemodilution and hypothermia in infants and small children (author's transl)].

Surgical corrections of some serious cardiovascular anomalies in infants and small children were attempted within the last 2 years; 12 severely ill infants and children below the age of 3 years were operated. All, but one, were below 10 kg of body weight, and in all of them there was a considerable weight deficit, more than 30%. The risk of operation was undertaken because of the ineffectiveness of medical treatment and very bad prognosis.

[Congenital heart diseases in newborns and infants; early detection, differentiation and accuracy of clinical diagnoses (author's transl)].

In order to facilitate for the general physicians the making of a suitable selection of babies who are in the most urgent need of specialized treatment at cardiac centres, simple methods for diagnosing and qualifying congenital cardiovascular diseases were elaborated. The following "minor" criteria were taken for suspecting a CHD: 1) cardiorespiratory distress following birth, 2) sequentially repeated Apgar score below normal, 3) "pneumonia" symptoms with respiratory distress, dyspnoea and cyanosis, attacks of unconsciousness, 4) feeding difficulties, failure to thrive, inexplicable irritability, 5) presence of other congenital anomalies. The almost certain presence of serious heart disease should be recognized in children, showing the following "major" symptoms: 1) permanent cyanosis, pallor or greyish colour, 2) cardiorespiratory failure (resembling usually symptoms of pneumonia), 3) ECG patterns indicating ventricular hypertrophy signs, 4) other significantly abnormal ECG patterns (e.
