ABSTRACT:
In some situations, the neonatal mortality rate in dogs can be high, and perinatal and postnatal veterinary care is essential to improve survival. This study to compared the Apgar score, serum lactate levels, and blood gas analysis results in 30 neonates born by elective cesarean section (GCE, n = 18) or cesarean section due to dystocia (GD, n = 12). Neonates were assessed at five time points: T0, at birth; T1, 3 h after birth; T2, 6 h after birth; T3, 12 h after birth; and T4, 24 h after birth. At T0, in the GCE group, 55.6% of the animals presented with adequate vitality, while 38.8% showed moderate changes in the Apgar score. In the GD group, 83.3% of the neonates had severe loss of vitality. At T1, none of the GCE neonates and 8.3% of the GD neonates presented with vitality deficits. Hyperlactatemia was observed in 83.3% of the GD neonates, and mixed acidosis (metabolic and respiratory) was observed at T0 in most neonates in both groups (GCE, 55.6%; GD, 72.7%). Compared to GCE neonates, the acid-base disorders were more severe and their recovery slower in GD neonates. At T0, GD neonates had higher hyperlactatemia and a lower Apgar score (worse vitality) than those of GCE neonates.
