摘要

Blood lactate concentration is known to be a good prognostic indicator associated with the severity of illness and the patient's outcome both in human and veterinary medicine. It also plays a significant role in the assessment of the newborn, being a good indicator of fetal hypoxia and the ideal predictor of morbidity at term in babies. In veterinary neonatal medicine, hyperlactatemia is considered a valid prognostic marker in critically ill foals; moreover, blood lactate measurement has been proposed for the evaluation of newborn viability and the assessment of fetal distress during delivery in dogs. Unfortunately, only a few studies have been published concerning the canine species. The present work examines 67 brachycephalic newborn dogs and their mothers, with the aim to evaluate the time dependent changes of blood lactate and glucose concentration during the first 24 h after vaginal or caesarean delivery both in puppies and bitches. To our knowledge, this is the first published study examining the time-dependent changes of these parameters in the bitch after parturition. Within the studied population of puppies, non-surviving was significantly associated with a higher lactatemia and a lower APGAR score. Blood lactate was high at birth then progressively decreased during the first 24 h of life and a lack of normalization of blood lactate levels within this time interval was suggestive for a poor prognosis for the newborn dogs; moreover, the decrease appeared to be slower after vaginal delivery. Lactatemia also showed a positive correlation with glycemia at birth. Concerning the bitches examined, blood lactate was found to be significantly higher after vaginal delivery than after caesarean section; the normalization occurred within 24 h after parturition. Blood glucose level was significantly higher at 2 h from delivery both in the group of bitches submitted to caesarean section and in those undergoing natural whelping but no statistical correlation was found between maternal glycemia and lactatemia. The results of the present study highlighted that the monitoring of lactatemia during the first 24 h of life, in association with the assessment of the APGAR score at birth, can be an useful prognostic tool helping to identify the most severely distressed puppies and to provide them an adequate support.
