Parturition Flashcards
Parturition
Process of giving birth
What happens during parturition
Softening and effacement of cervix and developing uterine powerful contractions
Rupture of feral membrane is
Not essential as it can happen a few days before labour onset ,during labour or not at all
In active pause of stage 1 pregnancy what are regular contractions
3 every 10 minutes
Oxytocin is given in which phase why
Active phase stage 1
To augment contractions
Which stage of preg results in delivery of the baby
2
Stage 3 what is delivered
The placenta and insulation begins
Does uterus contract in stage 3
Yes to expel placenta and clamp down to minimise blood loss
Oxytocin is key in this
If fails give synthetic oxytocin or ergometrine
During pregnancy uterus is and cervix is
Uterus quiescent
Cervix is closed, forming mechanical and chemical barrier
This prevents early delivery and infection
As cervix softened it…
Shortens so is more easily dilated by uterine conditions
Cervical distension due to contractile activity causes?
Oxytocin release which promotes more contractions
Oxytocin used best when
Less used at early gestationa as oxytocin receptors are only lowly expressed in myometrium prior to term
Which weeek gestation do we need medical intervention
42
Who can time the birth of kids
Mother and fetus
The expansion of milk producing cells occurs when
Early (16 weeks) in case baby premature
