labour and delivery Flashcards
Define the first stage of labour
onset of labour (true contractions) until 10cm cervical dilatation
Define the second stage of labour
10cm cervical dilatation to delivery of the baby
Define the third stage of labour
delivery of the baby to delivery of the placenta
Pessaries containing what can be used to induce labour
prostaglandin E2 (dinoprostone)
What can help to reduce braxton hicks contractions
staying hydrated
relaxation
The first stage of labours has how many phases
3
phase one of the first stage of labour is called the
latent phase
during the latent phase
cervix dilates to 3cm
there are irregular contractions
during the latent phase the cervix dilates at roughly
0.5cm an hour
the second phase of the first stage of labour is called the
active phase
during the active phase the cervix dilates
from 3 to 7 cm
at roughly 1cm an hour
the third phase of stage one labour is called the
transition phase
during the transition phase the cervix dilates
from 7 to 10 cm
at roughly 1 cm an hour
the second stage of labour depends on the
3 p’s
What are the 3 p’s of the second stage of labour
power
passenger
passage
define longitudinal lie
the fetus is straight up and down
define transverse lie
the fetus is straight side to side
define oblique lie
the fetus is at an angle
define complete breech presentation
hips and knees flexed (like doing a cannonball jump into a pool)
define a frank breech presentation
hips flexed and knees extended, bottom first
define a footling breech presentation
foot through the cervix
7 cardinal movements of labour
Engagement
Descent
Flexion
Internal Rotation
Extension
Restitution and external rotation
Expulsion
How is descent measures
position of the baby’s head in relation to the mother’s ischial spines
What should prompt active management of the third stage of labour
Haemorrhage
or
More than a 60-minute delay in delivery of the placenta
