Diagnosis of the Compromised Equine Pregnancy

      A compromised equine pregnancy is commonly associated with a high risk of an unfavorable outcome, with maternal, fetal, and neonatal implications. The maternal consequences of a compromised pregnancy may vary from the premature interruption of gestation to reproductive and medical issues, which may interfere with the mare's general health or challenge its ability to carry another pregnancy to term. The impact of maternal or placental disorders on the intrauterine environment generally results in fetal or neonatal compromise that summarizes the effects of one or a combination of three mechanisms: hypoxia, infection, and derangement of in utero development. Fetal compromise may ultimately result in premature or complicated delivery, fetal demise, stillbirth, or abnormalities in neonatal development and behavior. The effects of fetal compromise are dependant on the nature, duration, severity, and stage of gestation of occurrence of the stressful condition.
