gestational HTN

29
Q

defined as a systolic BP of >160 mmHg or a diastolic BP of >110mmHg.

A

severe HTN

30
Q

Multi-systemic disease characterised by hypertension in pregnancy with the addition of significant proteinuria (greater than 300 mg/24 hours in the absence of a urinary tract infection, chronic renal disease or contamination of the urine) after 20 weeks gestation.

A

pre-eclampsia

31
Q

The commonest cause of blood coagulation failure in obstetrics. The blood fibrinogen level falls below the normal of 4-6 g/L. Usually secondary to severe placental abruption, severe pre-eclampsia, prolonged retention of a dead fetus, or amniotic fluid embolism.

A

hypofibrinogenaemia

32
Q

A malformation of the male penis where the urethra opens on it’s under surface or on the perineum

A

hypospadias

33
Q

Incision of the uterus via the abdominal route. This term is generally used for delivery of the fetus via abdominal route prior to viability - after this time the operation is termed a Caesarean section.

A

hysterectomy

34
Q

Penetration of the endometrium by the early fertilized ovum (blastocyst) which becomes completely surrounded by decidua occurs 6-8 days after ovulation.

A

implantation

35
Q

The uterus is retroverted and with enlargement becomes imprisoned in the pelvis, impacting beneath the sacral promontory leading to urethral obstruction and acute urinary retention.

A

incarceration of gravid uterus

36
Q

Fundal dominance is lost, intrauterine tension between contractions is increased, the uterus is tender on palpation, and the woman complains of backache.

A

uncoordinated uterine action

37
Q

Death in the first year of life of infants born alive (includes neonatal deaths). The rate is 5-10 per 1,000 births in developed countries

A

infant mortality

38
Q

Entrance to the vagina

A

introitus

39
Q

Uterus turned inside-out, usually due to pulling on the cord when the uterus is relaxed.

A

inversion of the uterus

40
Q

Yellow staining of the baby’s brain due to high blood levels of billirubin causing severe neurological damage (billirubin encephalopathy) or death

A

44
Q

Usually occurs after 36 weeks and is commoner in nulliparos; the presenting part enters the pelvis and thus reduces the pressure on the diaphragm; the mother notices that it is easier to breathe.
