Abstract:
Objective To study the gas analysis of umbilical cord artery blood and radial artery blood on predicating the prognosis of asphyxia neonate?Methods From September 2014 to September 2015, 328 neonates were divided into groups by Apgar score:290 patients in the control group and 27 patients in the mild asphyxia group,11 patients in the severe asphyxia group?After birth,umbilical artery blood,radial artery blood gas analysis was perfomed, oxygenation index was calculated, Outcome of neonatal behavioral neurological assessment ( NBNA) in neonates with asphyxia was regular follow?uped,the relationship between pH value and umbilical artery blood gas analysis was analyzed?Results The pH, PO2, PCO2 and oxygenation index of umbilical cord blood and radial artery blood in the severe asphyxia group was(7?11±0?25,(73?93±23?35) mmHg,(51?36±16?37) mmHg,206?23±98?12),significant different than the mild group(7?24±0?05,(86?35 ±12?56) mmHg,(45?89± 9?21) mmHg,411?22±57?94) and the control group(7?28±0?08,(87?80±12?07) mmHg,(43?68± 6?45) mmHg,426?23±73?30)(P<0?05)?The pH,PO2,PCO2 and oxygenation index of umbilical cord blood and radial artery blood in the severe asphyxia group was(7?25±0?18,(74?66±24?09) mmHg,(51?42±17?83) mmHg,332?03±65?19),significant different than the mild group(7?31±0?09,(87?24 ±11?75) mmHg,(45?73±10?21) mmHg,405?67±82?65) and the control group(7?32±0?06,(87?99±11?81) mmHg,(42?84± 9?32) mmHg,439?89±60?76)(P<0?05)?The NBNA scores of the severe asphyxia group was (34?09±5?02) points,lower than the mild group(36?62±2?04)(F=21?65,P<0?05)?The NBNA scores showed significant relationship with umbilical cord blood pH in the severe asphyxia group( r=0?877,P<0?01)?Conclusion The pH,PO2 and oxygenation index of umbilical cord blood and radial artery blood was lower while PCO2 was markedly high in the severe asphyxia group than other groups?For neonates, there is a correlation between umbilical cord blood pH and NBNAs core, neonates borned with hypoxia and acidosis should monitor blood gas analysis and oxygenation index dynamically
