The objective of this study was to investigate the impact of parturition type on vitality in newborn puppies, their weight gains, and survival in the first week postpartum. One hundred and twenty-three puppies were divided in three groups: vaginal parturition (VP), emergency (EM-CS), and elective cesarean section (EL-CS). Apgar scores were assessed 5, 15, and 60 min postpartum. Lactate and glucose concentrations were measured in amniotic fluid and umbilical blood; cortisol concentrations were measured in amniotic fluid and puppy urine. Puppies' weight gain was tracked daily for 7 days postpartum. Apgar score at 5 and 15 min was significantly better in the VP group. EL-CS puppies had significantly lower umbilical blood and amniotic fluid lactate concentrations compared to the VP group, which also had higher umbilical blood lactate concentration than EM-CS puppies. The cortisol concentration in the amniotic fluid and in urine differed significantly between the groups, with the highest concentration in the EM-CS, followed by the VP group. Glucose concentration in amniotic fluid was higher in the VP group than EM-CS group. The type of parturition had no impact on puppies' weight gain or their survival at birth; however, supportive treatment was provided for non-vital puppies. Non-invasive analysis of puppies' fluids could help in the assessment of the neonatal vitality.
本研究的目的是调查分娩类型对新生幼犬活力、体重增加以及产后第一周存活率的影响。123只幼犬被分为三组:阴道分娩(VP)、急诊剖宫产(EM-CS)和择期剖宫产(EL-CS)。产后5分钟、15分钟和60分钟评估阿氏评分。测量羊水和脐血中的乳酸和葡萄糖浓度;测量羊水和幼犬尿液中的皮质醇浓度。产后7天每天跟踪幼犬的体重增加情况。VP组在5分钟和15分钟时的阿氏评分明显更好。与VP组相比,EL-CS组幼犬的脐血和羊水乳酸浓度明显更低,而VP组的脐血乳酸浓度也高于EM-CS组幼犬。各组羊水和尿液中的皮质醇浓度差异显著,EM-CS组最高,其次是VP组。VP组羊水葡萄糖浓度高于EM-CS组。分娩类型对幼犬的体重增加或出生时的存活率没有影响;然而,对无活力的幼犬提供了支持性治疗。对幼犬体液的非侵入性分析有助于评估新生儿活力。
