Karten in diesem Stapel (12)
- 1Principal associations of cerebral palsyPreterm
IUGR
Congenital abnormalities
Intrapartum fetal distress
Pre-eclampsia
Infection - 2Define small for dates (SFD)/small for gestation (SFG)The weight of the fetus is less than the tenth centile for its gestation
- 3Identification of the high-risk pregnancy: prepregnancyPoor past obstetric history or very small baby
Maternal disease
Assisted conception
Extremes of reproductive age
Heavy smoking or drug abuse - 4Identification of the high-risk pregnancy: during pregnancyHypertension/ proteinuria
Vaginal bleeding
Small for dates (SFD) baby
Prolonged pregnancy
Multiple pregnancy - 5Identification of the high-risk pregnancy: investigationsCervical scan at 23 weeks
Uterine artery Doppler
Maternal blood tests, e.g. PAPP-A - 6Methods of surveillance in the high-risk pregnancyFortnightly (max.) US - growth
Umbilical artery Doppler - identify compromised fetus
CTG on a daily basis
Methods specific to disorder, e.g. blood pressure in pre-eclampsia - 7In what three ways can ultrasound scans be used to monitor whether fetal growth is healthy?1. Comparison to previous scans
2. Compare growth of abdomen to that of the head (abdo growth will slow before head growth if compromised)
3. Compare actual growth against expected growth for individual fetus - 8Cardiotocography (CTG)Fetal heart is recorded electronically
Accelerations and variability >5 bpm should be present
Decelerations should be absent
Rate should be 110–160 bpm - 9Constitutional determinants of smaller fetal size and growthLow maternal height and weight
Nulliparity
Asian ethnic group
Female fetal gender - 10Pathological determinants of fetal growth causing IUGRPre-existing maternal disease
Pre-eclampsia
Multiple pregnancy
Smoking
Drug usage
Infection e.g. CMV
Extreme malnutrition
Congenital abnormalities - 11What are the risks of prolonged pregnancy?More common: stillbirth, neonatal illness, encephalopathy, meconium passage, fetal distress
- 12Management of prolonged pregnancyFrom 41 weeks: Examine the patient vaginally and induce unless cervix very unfavourable (not ripe), or patient prefers to wait
If no induction: sweep cervix and arrange daily CTG
