cervix is 3-4cm dilated

Q

what is cervical effacement?

A

the shortening and thinning of the cervix

17
Q

what is foetal station?

A

the relationship of the presenting part to the ischial spines
measured in cms above and below the ischial spines

18
Q

what is the second stage of labour?

A

the delivery of the baby
mother pushes with pelvic floor msucles
with each contraction the presenting part is pushed downwards into the placental floor

19
Q

what is the third stage of pregnancy?

A

the delivery of placenta and membranes

20
Q

why do we give mothers synthetic oxytocin after delivery of the placenta?

A

as there are open vascular beds so the uterus needs to contract to cause haemostats and avoid postpartum haematosis

21
Q

how is delivery of the placenta carried out?

A

controlled cord traction

or by mother pushing

22
Q

what are the 7 cardinal movements of labour?

A 
engagement
descent
flexion
internal rotation
extension
external rotation
expulsion

24
Q

what is a Partogram?

A

a composite graphical record of key data (maternal and fetal) during labour entered against time on a single sheet of paper. Relevant measurements might include statistics such as cervical dilation, fetal heart rate, duration of labour and vital signs.

25
Q

why is it important to have regular bladder emptying in labour?

A

so the bladder doesnt become overdisteded and damage the detrusor muscle as this can cause complications for urinating post fatally

26
Q

what type of analgesia can be given during labour?

A

oral analgesics e.g. paracetamol or codeine
transcutaneous electrical nerve stimulation
entenox
systemic opiates
epidural

27
Q

what is Cardiotocography?

A

a technique used to monitor the fetal heartbeat and the uterine contractions during pregnancy and labour.

28
Q

what are the complications of prolonged labour?

A 
foetal distress due to o2 deprivation
inter cranial haemorrhage 
sepsis
increased chance of instrumental use
long term risk for injuries like cerebral palsy and seizure disorders
29
Q

what is augmentation of labour?

A

the process of stimulating the uterus to increase the frequency, duration and intensity of contractions after the onset of spontaneous labour.

30
Q

how is augmentation of labour done?

A

by giving oxytocin

31
Q

whats the differnce between augmentation of labour and induction?

A

Induction of labor is defined as the artificial process of initiating labor before spontaneous onset. Augmentation of labor is the stimulation of uterine contractions once the woman has spontaneously initiated labor- because progress is considered inadequate
