Apgar score is most widely used evaluating indicator of newborn health, but it is very subjective. Umbilical cord blood gas analysis is more objective and effective than Apgar score in evaluation of newborn status. Cord blood gas was changed slightly by processing of time after fetal birth. This study was undertaken to observe objectiveness and effectiveness of umbilical arterial blood gas analysis and effects of time interval of cord clamping to newborn health with 122 pregnant women and their babies. We observed following results: 1. There were poor correlation between Apgar score and umbilical cord arterial blood analysis in evaluating of newborn health (P>0.05). 2. There was no clinical significance of Apgar score or umbilical arterial blood gas analysis as single indicator in evaluating of newborn health (P>0.05). 3. Gas analysis and pH of umbilical arterial blood was more helpful in evaluating of newborn health than Apgar score. 4. There were no significant effects of time interval of umbilical cord clamping to newborn health. 5. If there were no indications of early umbilical cord clamping, cord blood sampling at immediately after birth without cord clamping was more effective to evaluate newborn status.
Key Words: Apgar score, Umbilical arterial gas & pH, Cord clamping time, Newborn health
