What are the signs and symptoms of the onset of labour?
|
Painful regular uterine contractions
A show Rupture of the membranes Diagnosis is by effacement (shortening) and dilatation of the cervix |
|
|
What is the uterine action in a contraction?
|
contraction wave starts near one or other cornu. This spreads in the myometrium, taking 10-30 seconds to reach the whole uterus. The contraction may take another 30 seconds to reach its peak.
Duration of contraction is greater in the upper than the lower segment – result is effacement. |
|
|
What does an abnormal wave patterns with lack of dominance of the upper segment lead to?
|
uncoordinated uterine contractions, i.e. dysfunctional labour
|
|
|
What is the role of oxytocin?
|
Protein hormone, 8 amino acids from posterior pituitary
Increased myometrial and decidual oxytocin receptors in late pregnancy Effective in augmenting uterine contractions |
|
|
What is a Partogram?
|
Graph of cervical dilatation against time
First stage of labour Start partogram when labour diagnosed |
|

|
What are the Causes of abnormal labour?
|
3 Ps
Powers (Uterine contractions) Passage (Capacity of the pelvis) Passenger (Fetal size/ cephalopelvic disproportion) Passenger |

|
What is a shoulder dystocia?
|
Shoulders held up by pubic bone in a head delivery.
Placenta separated=no fetal blood supply. Risk of fetal damage |
|
|
Can you predict a shoulder dystocia?
|
Increases with birthweight, but 50% in babies of normal birth weight.
|
|
|
What are the warning signs of shoulder dystocia?
|
Prolonged first stage
Prolonged second stage Assisted delivery Fetal head retracts against the perineum after delivery |
|
|
What the fuck do you do in a shoulder dystocia!?!?!?!?
|
Helperr
H=call for help E=evaluate for episiotomy L=legs McRoberts P= external pressure E=enter for wood screw manoeuvre R=remove posterior arm R=role deliver posterior arm. |
