ABSTRACT
For the neonatal patient, precocity of diagnosis is crucial for effectiveness of medical approach. However, the newborn has its own physiological peculiarities due to ongoing adaptive mechanism for extrauterine life and deserves special attention in order to underline a specific management or clinical approach. The objective of this work was to verify clinical adaptations and biochemical balance of neonates during immediate period, with special reference to haematological, renal and metabolic functions. Neonatal puppies (n = 51) were physically examined for vitality and rectal temperature at birth, 5 and 60 min post-birth. Blood was collected at birth and 60 min post-birth for analysis of glucose, sodium, potassium, chlorine, blood urea nitrogen (BUN), haematocrit and haemoglobin. Neonatal vitality was lower at birth compared with 5 min and 60 min post-birth. Progressive decline in rectal temperature (36.5 ± 0.3°C, 34.2 ± 0.2°C, 32.3 ± 0.5°C) was observed at birth, 5 min and 60 min post-birth, respectively. Puppies presented slight hyponatremia (140.7 ± 0.5 mmol/L) at birth and hypopotassemia (3.5 ± 0.1 mmol/L) and blood urea nitrogen (13.1 ± 0.7 mg/dl) during the first hour, and high haematocrit (45.1 ± 1.0%) and haemoglobin (15.3 ± 0.3 g/dl) concentration. In conclusion, puppies had rapid evolution of vitality. Marked decrease in rectal temperature occurred at 5 min post-birth. Haematological values of neonates immediately after birth reflected mainly the dam's blood status, not being useful for a blood panel at this time point. The peculiar pattern of BUN, sodium and potassium observed during transition period, suggested that specific reference range should be considered for neonatal puppies.
