Maternal / fetal blood gases and PH in anaemic patients during labour

ABSTRACT

One hundred anaemic women, during labour, with hemoglobin were <10 g/dl, and 20 non-anaemic cases of the same age and parity groups, with hemoglobin > 10 g/d. This study was conducted in Al-Azhar University Hospitals during a period of 18 month starting from March 2000. The effect of maternal anaemia on the maternal fetal blood gases and pH was studied in two groups. The maternal oxygen concentration of the anaemic cases, showed a statistically significant, compared with the oxygen level of the control group, the decreased oxygen level between the 2 groups was clearly manifest during the second stage of labour. Uterine concentration of the second stage of labour result in a significant increase in the maternal PCO[2], HCOO[3] levels among the anaemic cases compared with the control group. The maternal pH value of the anaemic group showed a non significant increase in comparison with the pH level of the control group. The fetal blood gases and pH [O[2], CO[2], HCO[3]] and pH of the neonates of the mildly anaemic mothers showed no significant change when compared with the values of the control neonates
