Abstract

---

Aim: This study was conducted with the objective of identifying and evaluating intrapartum fetal stress in connection with the type of delivery in bitches.

Materials and Methods: A total of 26 bitches between 1 and 5 years, belonging to 10 different breeds were evaluated. Bitches were subjected to detailed clinico-gynecological examination based on history. Neonatal stress associated with spontaneous whelping (SW), assisted whelping (AW), and emergency cesarean section (EC) was evaluated using umbilical vein lactate (UL) estimation by collecting the blood from umbilical vein.

Results: A high umbilical vein lactate value was associated with fetal distress. The mean umbilical lactate value was highest in EC (12.54±0.8 mmol/L) followed by AW (8.86±0.9 mmol/L) and the lowest value was found in SW (7.56±0.58 mmol/L). A significant increase (p<0.05) in umbilical lactate level was observed in EC group of canine neonates compared with AW and SW groups. Overall mean umbilical lactate values of neonates which died within 24 h (13.31±1.08 mmol/L) and the neonates which survived beyond 24 h (8.87±0.55 mmol/L) differed significantly at 5% level.

Conclusion: Immediate identification of neonatal distress by use of umbilical vein lactate estimation is helpful for the clinician to undertake resuscitation or medical therapy to ensure better neonatal survivability.
