<ul data-deprecated="true"><li data-deprecated="true"><p data-uuid=null data-created-at=null>The class continues Chapter 2 on equine obstetrics, focusing on parturition and placental assessment. Emphasis is placed on proper management of pregnant mares, monitoring gestational risk, and recognizing when intervention is needed.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Foaling must always be attended, though not always intervened. Physiological preparation includes hormonal changes, cervical maturation, and increasing uterine contractility driven by oxytocin, estrogen, and prostaglandins.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Fetal readiness for birth depends on activation of the HPA axis and cortisol release, which is critical for survival. Premature or dysmature foals (<320 days or insufficiently matured) often suffer from pulmonary immaturity, inadequate surfactant, incomplete ossification, and underdeveloped immune systems.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Immune maturation involves shifting neutrophil-to-lymphocyte ratios from 1:1 to 3–4:1 near term, driven by cortisol. Assessments of this ratio assist in prognosis.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Predicting foaling is challenging, especially in primiparous mares, which show fewer signs and may lack mammary development. Multiparous mares exhibit vulvar relaxation, pelvic ligament softening, udder filling, and waxing.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Monitoring methods include daily evaluation of mammary secretion pH using commercial test strips, with noted variability in young, old, or minimally developed mares. Additional tools include Foal Alert, Easy Foal, and Foal App, though none replace in-person supervision.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Induction of labor is generally discouraged due to risks of inadequate fetal maturation. It is reserved for mares with severe systemic compromise. Off-label protocols using betamethasone or dexamethasone may support fetal maturation prior to induction. Oxytocin (diluted IV or IM), lidocaine cervical gel, or misoprostol may be used during induction.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Normal foaling requires anterior presentation, dorsosacral position, and extended posture. Three stages of parturition are described: Stage 1 (up to 4 hours, behavioral signs), Stage 2 (expulsion, critical—should be under 20 minutes), Stage 3 (placental expulsion within 30 minutes to 3 hours).</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Assisted deliveries require rapid detection of abnormalities, avoiding premature amnion rupture, and coordinating traction with uterine contractions. Correct timing ensures optimal fetal oxygenation and blood transfer via the umbilical cord.</p></li><li data-deprecated="true"><p data-uuid=null data-created-at=null>Post-birth monitoring includes ensuring mare–foal bonding,</p></li></ul>

Relembrando um pouquinho que na aula anterior a gente falou da importância do manejo da gestante, da escolha do ambiente e do monitoramento gestacional que hoje através dele nós conseguimos então observar patologias gestacionais que estão se desenvolvendo, classificar éguas de gestação de alto risco e instituir então o manejo que é o manejo de avaliação obstétrica que pode ser mensal, quinzenal, semanal ou até diário a depender da nossa égua.
