1M - Parturition Flashcards
Clinical labor is what phase of parturition?
Phase 3
This is the quiescence stage of parturition?
Phase 1
This is the phase of parturition where contractile unresponsiveness and cervical softening are manifested?
Phase 1
This phase of parturition involves the uterine preparation for labor, cervical ripening and formation of the lower uterine segment?
Phase 2
What are the stages of labor?
Contraction, cervical dilation and fetal and placental expulsion
This phase of parturition involves the involution of the uterus, cervical repair and breastfeeding?
Phase 4
This phase of parturition can be called the phase of parturient recovery?
Phase 4
What do you call the low intensity myometrial contractions that are felt during the quiescent stage and this normally do not cause cervical dilation?
Braxton Hicks contractions or false labor
To maintain quiescence, prostaglandins are are markedly increased? T or F?
False
They are suppressed
What genetic defects can cause cervical insufficiency during pregnancy?
Ehler Danlos Syndrome and Marfan syndrome
This phase of parturition may also be called the phase of uterine awakening or activation?
Phase 2
When does phase 2 of parturition start?
Last few weeks of pregnancy
How long does the Phase 1 of parturition last?
Start of pregnancy until near the end of pregnancy
Phase 2 of parturition happens because of the withdrawal of what hormone?
Progesterone
This phase of of parturition involves the formation of the lower uterine segment and the descent of the fetus to or through the pelvic inlet?
Phase 2
Oxytocin receptors level rise during phase 2 of parturition, what are the primary regulators of oxytocin receptor expression?
Estrogen and progesterone
This hormone maintains uterine quiescence through inhibition of myometrial oxytocin response?
Progesterone
This substance is largely responsible for the structural disposition of the cervix?
Collagen
Production of these substances during cervical ripening is thought to increase viscoelasticity, hydration and matrix disorganization?
Glycosaminoglycans and proteoglycans
Inflammatory substances are increased during stage 2 of parturition. T or F?
True
Therapies to prevent cervical ripening are present? T or F?
False
What are the fetal contributions to parturition?
Fetal stretch, Fetal endocrine cascades, Surface Protein A
This fetal substance from the placenta and decidua is required for lung maturation of the fetus?
Surface Protein A
Before 37 weeks of gestation, and before lightening, what organs does the uterus compress into?
Lungs and diaphragm
