Difficulty delivering the shoulders after delivery of the fetal head

40
Q

Puerperium

A

The 6 weeks following delivery

41
Q

Quickening

A

Maternal perception of fetal movements

42
Q

Restitution

A

Rotation of the fetal head after delivery to align with the back and shoulders

43
Q

Show

A

A discharge of blood and mucus from the vagina in early labour or the days preceding labour

44
Q

Phototherapy

A

Use of standard fluorescent white light or blue light therapy to photoisomerise bilirubin to allow for its excretion

48
Q

Neonatal respiratory distress

A

Tachypnoea, increased effort of breathing, noisy breathing and central cyanosis

49
Q

Caesarean hysterectomy

A

Laparotomy at which the contents of the gravid uterus are delivered, then the uterus is excised (e.g. due to placenta accreta)

50
Q

Perimortem CS

A

Caesarean performed on a moribund or dead woman with a view to preserving her life

51
Q

Augmentation of labour

A

The process of stimulating a labour that has already started

Q

Vasa praevia

A

54
Q

Antepartum haemorrhage

A

Bleeding >5ml from the vagina after 20 weeks gestation

55
Q

Abruption

A

Separation of the placenta from the uterus in the antenatal or intrapartum period

70
Q

Position

A

The relationship of a defined area on the presenting part (the ‘denominator’) to the mother’s pelvis. In a cephalic presentation, the denominator is the occiput, thus the fetal position is described as occipito-anterior (OA), occipito-posterior (OP), left or right occipito-transverse (L/ROT).
