Induction and Augmentation of labour Flashcards
Define Induction of labour
Artificial initiation of where by it is believed that the outcome of the pregnancy will be better if it is artificially interrupted rather than being left to follow its natural course Nice 2008
What is a membrane sweep?
VE: Separation of chorionic membrane from the decidua and stimulate prostoglandin levels. Which increases the likelihood of spontaneous labour.
When should a sweep be performed?
Primip: 40weeks and 41 weeks
Multip: 41 weeks
Indication for induction?
Diabetes
Prevent prolonged pregnancy
PROM >37week (>24hours)
IUD
What complications can arise?
Uterine hyperstimlulation
Uterine rupture
Cord prolapse
What is used for inducing labour?
Vaginal prostaglandin E2 - PGH2
tablet, gel, pessary
Management of PGH2 in each form?
tablet and gel- one does followed by a second if not in established labour 6hours
pessary one does over 24hours
If failed - women and fetus fully assessed (CTG)
further attempt at induction
caesarean
What should be recorded prior to induction? X2
FH
Bishop score
When is the women to contact the hospital after gel or tablet?
when contractions begin
has no contractions <6hours
How to prevent hyperstimulation
tocolytic
How to prevent cord prolapse
Before IOL: engagement of presenting part
palpate foe umbilical cord presentation
ARM avoid if head high
What is the definition of augmentation of labour?
Augmentation of labour is the process of stimulating the
uterus to increase the frequency, duration and intensity of
contractions after the onset of spontaneous labour WHO 2014
Indications for augmentation?
Confirmed delay in labour
Contraction insufficiently strong OR
uncoordinated to dilate cervix
What is established delay in first stage of labour?
Primip: <2cm/4hours
multip:<2cm/4hours or slowing in progression
If delay confirmed in 1st stage what should be the management?
Amniotomy bishop score >7 VE 2hours following if <1cm consider oxytocin
