title: [Comparative monitoring of pre-ejection-period and transcutaneously measured pO2 in neonatal period (author's transl)].
abstract: Pre-ejection period (PEP) and transcutaneous measured pO2 (tc pO2) were monitored simultaneously with the beat-to-beat ECG in 55 cases of unselected neonates. In addition body weight, acid-base-status and body temperature were registered 11 neonates were monitored immediately post partum, the others at various times until 9 days after delivery.
  
  
  RESULTS
  The mean value of PEP after delivery is 63,3 msec. There is a negative correlation between neonatal heart rate and Pre-ejection-period. Increases of body temperature leads to a decrease of the PEP and vice versa. There are no direct significant alterations in PEP in connection with changes in neonatal tc pO2. Only when tc pO2-values beyond 20 mmHg were registered in distressed neonates PEP shortened significantly. PEP shortened also in periods of neonatal crying PEP is not correlated to birth weight or the actual neonatal weight when measurement of PEP and tc pO2 was performed.
