Abortion/miscarriage
Pregnancy loss before 20 weeks gestation
Labour
Regular painful contractions with cervical change after 20 weeks gestation
Lower uterine segment caesarian section
Operative delivery of the baby through an incision in the lower uterine segment
Classical caesarean section

Lecture: Vertical incision into uterine body
Hysterotomy

Premature prelabour rupture of membranes (PPROM)
Rupture of the membranes before labour at less than 37 weeks gestation
ARM/AROM

SROM
Spontaneous rupture of the membranes
Braxton Hicks contractions
Painless uterine contractions in the antenatal period
Naegles rule
To estimate the probable date of confinement: Add 9 months & 7 days to the first day of the LMP. A correction is required if the patient does not have 28 day cycles
First stage of labour
From the start of labour until full dilatation of the cervix
Second stage of labour
From full dilatation of the cervix until birth of the baby
Third stage of labour
From the birth of the bay until the delivery of the placenta and membranes
Spurious or false labour
Uterine contractions which may be regular and/or painful, but are not associated with cervical effacement and dilatation
Oxytocic
Medication that stimulates contractions of the uterine muscle
Tocolytic
Medication to stop uterine contractions
Induction of labour
The process of causing labour to commence
Augmentation of labour
The process of stimulating a labour that has already started
Placenta praevia
Placenta that approaches or covers the internal cervical os in late second or third trimester
Vasa praevia

Antepartum haemorrhage
Bleeding >5ml from the vagina after 20 weeks gestation
Abruption
PCP: Separation of the placenta from the uterus in the antenatal or intrapartum period
Lecture: “Premature separation of a normally implanted placenta prior to delivery of a fetus”
Post partum
haemorrhage

Lecture: “Placenta that is moribidly adherent to the myometrium”
Uterine atony
Abnormal relaxation of the uterus after delivery, usually causing bleeding
Isoimmunisation
Blood group antibodies cross the placenta resulting in haemolysis of fetal red blood
cells. Antibodies include D, c, K (Kell), Kidd, Duffy etc.

weighing >400gm if gestation is unknown
Stillbirth
