FULL DILATAION

3

in nulliparous women delivery considered prolonged if it lasts longer than?

3 hours

4

how long does expulsion of the placenta usually take?

10 mins, but can be longer

5

active management - delivery of placenta - why

lower risk of post part haemorrhage

6

admin of oxytocin, ergometrine, cord clamping and cutting, injection of oxytocin directly in to chord

.

7

why do you get cervical softening?

increase in hyaluronic acid gives increase in molecules among collagen fibres. decreased bridging causes decrease in firmness of cervix. decrease in tensile strength, increase in cervical decorin

8

painless contractions, resolve with ambulation/change in activity/position?

braxton hicks

9

what are these?

tightening of uterine muscles, thought to aid the body to prepare for birth

10

when can they start from?

6 weeks

11

abdomen hard, come and go, 5 minutes apart, evenly spaced reduction in time between contractions. what does the body release during these contractions?

oxytocin

12

greatly painful, don't resolve with change of position

.

13

what collagen types are present in the cervix?

1-4

14

what acts as pacemaker in contractions?

tubal ostia

15

front suture, in line with sagittal?

metropic

burning/stinging feeling for the mother

20

name of the procedure carried out t prevent tearing of anus>

episiotomy

21

5 parameters for assessing the cervix?

EDLFP - effacement, dilataion, level of presenting part, firms, position

22

normal blood loss at pregnancy?

less than 500ml

23

if greater?

abnormal

24

more significance if above?

1500ml

25

any blood loss prior to delivery is abnormal and needs to be referred to consultant unit

.

collostrum - rich in antibodies, but no ?

fat

31

decrease in oestrogen and progesterone. lactation is initiated by placental expulsion

if placenta not out by 1 hour, prepare for removal under GA

32

what inhalation agent acts as anaesthetic?

entonox

33

does epidural impair uterine activity?

no, but it might slow stage 2

34

complications?

hypotension, dural puncture, headache, back pain, atonic bladder

35

failure to progress at stage 1 - dilation?

if dilation less than 2 cm in 4 hours
