Terminology Flashcards
Nullipara
A woman who has never been pregnant beyond 20/40
Gravid
Number of pregnancies, regardless of outcome
Para/Parity
The number of babies born after 20/40
G6P4
Gravida 6, Para 4 6 pregnancies (including current pregnancy) and has previously delivered 4 babies at more than 20/40
Grand multipara
A woman who has delivered 5 or more babies at more than 20/40
Abortion/miscarriage
Pregnancy loss before 20/40
Labour
Regular painful contractions with cervical changes after 20/40
Lower uterine segment caesarean section (LUSCS)
Operative delivery of the baby through an incision in the lower uterine segment
Classical caesarean section
Operative delivery of a baby through a vertical incision in the upper segment of the uterus
Hysterotomy
Operative delivery of the baby through a uterine incision at less than 20/40
Preterm labour
Labour at less than 37/40
Prelabour rupture of membranes (PROM)
Rupture of the membranes before onset of labour
Premature prelabour rupture of membranes (PPROM)
Rupture of the membranes before labour at less than 37/40
ARM/AROM
Artificial rupture of membranes
SROM
Spontaneous rupture of membranes
Braxton Hicks contractions
Painless uterine contractions in the antenatal period
Naegles rule
To estimate the probable date of confinement.
Add 9 months and 7 days to the first day of the last menstrual period. A correction is required if the patient does not have 28-day cycles
First stage of labour
From the start of labour until full dilation of the cervix
Second stage of labour
From full dilation of the cervix until birth of the baby
Third stage of labour
From the birth of the baby 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 the contractions of the uterine muscle
Tocolytic
Medication to stop uterine contractions
Induction of labour (IOL)
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
Foetal vessels lying in the membranes in front of the presenting part
Antepartum haemorrhage (APH)
Bleeding >5mL from the vagina after 20/40
Abruption
Separation of the placenta from the uterus in the antenatal or intrapartum period
Postpartum haemorrhage (PPH)
PV bleeding of >500mL in the first 24h post delivery
Secondary post partum haemorrhage
PV bleeding of >500mL more than 24h post delivery
Placenta accreta
PLacenta that invades 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 the foetal red blood cells.
Antibodies include D, c, K (Kell), Kidd, Duffy etc
CTG
Cardiotocograph
Neonatal death
A liveborn infant who dies within 28 days of birth, of at least 20/40 or weighing >400gm if gestation is unknown
Stillbirth
An infant born after 20/40 (or birthweight >400gm if unknown gestation) who did not show any signs of life after birth
Perinatal mortality rate
The number of stillbirths plus neonatal deaths per 1000 births
Maternal death
The death of a woman while pregnant (irrespective of the gestation) or within 42 days of the conclusion of the pregnancy irrespective of the cause of death or gestation at delivery
Maternal mortality rate
Number of maternal deaths per 100,000 births
Infant death
Death of an infant b/w 29 days and 1 year of life
Station
The level of descent of the presenting part relative to the pelvic brim or symphysis on abdominal palpation, or to the ischial spines on vaginal examination
Lie
The relationship between the long axis of the foetus and the long axis of the uterus
Eg: longitudinal, oblique, transverse
Position
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 foetal position is described as occipito-anterior (OA), occipito-posterior (OP), left or right occipito-transverse (L/ROT). In a breach presentation, the denominator is the sacrum (SA, SP, ST)
Presentation
The part of the foetus which is presenting
Eg vertex, breech
