Q

what is the definition of

  • LMP
  • Cycle
  • Parity
  • Gravidity
A

LMP = first day of last normal menstrual period

Cycle = number of days from first day of bleeding to next period e.g. 5/28 is 5 days of bleeding with 28 day cycle

Parity = number of deliveries after 24 weeks incl stillborn, miscarriage, terminations and ectopic pregnancies, if terminated before 24 weeks, ^x

Gravidity = total number of pregnancies inc current pregnancy, regardless of outcome

29
Q

how often are contractions at the maximum during labour

A

5 every 10 mins

30
Q

describe stage 1 2 3 of labour

A

stage 1 onset of labour to full dilatation of cervix (10cm)

stage 2 full dilatation to delivery of baby

stage 3 delivery of baby and placenta

31
Q

describe stage 1 of labour

A

latent phase - irreglar painful contractions, start of cervical changes, up to 4cm dilatation

active phase - regular painful contractions + 10cm dilatation

32
Q

how is stage of descent described using the fifths and ischial spines?

A

before baby head at ischial spines, palpate abdomen to feel for how much of baby head is still above, count in fifths (e.g. 4/5ths of baby head is above)

when baby’s head is at ischial spines, that is zero station, once below is +1 station e.g

33
Q

how are fetuses monitored during labour

A

intermittent auscultation with doppler or pinnard - 1 min, after contraction every 15 minutes for first stage and every 5 mins in second stage

34
Q

what pharmacological options are there for women in labour?

A

paracetamol
entonox
diamorphone
epidurals

35
Q

describe second stage of labour

A

passive second stage - from full dilatation, allow spontaenous descent, don’t push yet.

active second stage, when head is visible, encourage mother to push

36
Q

mechanism of body regarding babies’ positions

A
descent
flexion
internal rotation
crowning
extension
restitution
internal rotation of shoulders
expulsion
37
Q

what is caput succedaneum

A

temporary swelling of head due to compression by cervix

38
Q

when is the cord cut?

A

after pulsation of cord stops

39
Q

ways that placenta can be delivered

A

physiological or active

40
Q

different degrees of perineal tear

A

1st degree is down to fourchette
2nd is skin, vaginal wall and perineal muscles
3rd includes anal sphincter
4th includes rectum

41
Q

what to inspect the placenta for?

A

is it complete, how many vessels? (3), how many membranes (2), any malformations, histology or cytogenetics

42
Q

most common cause of abnormal labour regarding “powers”

A

inefficient uterine action

hyperactive uterine action

43
Q

how to manage inefficient uterine action?

A

augmentation - ARM, oxytocin

44
Q

common abnormal fetal presentations

A
OP
OT
brow
face
breech
45
Q

management of different abnormal fetal presentations

A
OP - instrumental
OT - CS if progress to deep transverse arrest
brow - C section
face - C section if chin is posterior
breech - C section
46
Q

what is deep transverse arrest

A

if baby is stuck in OT position after 1 hour

47
Q

common causes of abnormal labour regarding Passage

A

cephalo-pelvic disproportion (head>pelvis)

48
Q

2 types of forceps

A

rotational and non-rotational

49
Q

where are rotational forceps used?

A

in theatre because failure => csection

50
Q

which instrument is more likely to fail

A

ventouse

51
Q

why can using a ventouse cause jaundice to the baby

A

suction causes bruising on head leading to blood break down and build up of heme

52
Q

what are the indications for isntrumental delivery

A

prolonged 2nd stage leading to maternal exhaustion

fetal compromise

prophylatically in high risk pregnancies

53
Q

what analgesic is given to the mother in a low cavity instrumental delivery

A

pudendal block/local anaesthesia.

low cavity = baby below 0 station

54
Q

prerequisites for instrumental delivery

A

maximum 1/5s head palpable on abdomen

cervix fully dilated

analgesia

consent
empty bladder
consider venue e.g theatre

55
Q

what can be done to reduce instrumental delivery rates

A

midwife encouragement

encourage mobilisation of

mother during labour

altering maternal position

using oxytocin for slow 2nd stage progress

allow longer passive 2nd stage when epidural present

56
Q

definition of inducing labour

A

at least 24 weeks gestation

intact or ruptured membranes, but not active labour

57
Q

61
Q

what is included in the modified bishops score

A
dilatation

head station
62
Q

what do the scores in the modified bishops score mean

A

less the points the less advance labour

> 9 means labour imminent

63
Q

risks of labour induction

A
