Comparative maternal lactate-pyruvate ratios in singleton and twin pregnancies and in babies delivered at term.
The lactate-pyruvate (L/P) ratio was used for assessment of anaerobic metabolism, hypoxia or oxygen debt in uterine contractile muscle during labour and immediately after parturition. The mean blood lactate level was significantly higher in mothers with twin pregnancies (P<0.001) than in singleton pregnancies at term. L/P ratios were markedly elevated in established labour both in mothers of singleton as well as in mothers of twin pregnancies and were also higher in cord blood of the twins than those of singleton babies (P<0.001). The twins delivered second had higher L/P ratios (P<0.05) than the leading twins.
