Complications Flashcards
Potential causes of IUGR
Placental insufficiency
Fetal chromosomal abnormalities
Single umbilical artery
Most common type of IUGR
Asymmetric
Oligo, increased placental maturity, thin placenta are factors associated with:
Asymmetric IUGR
Side effects of chronic fetal hypoxia
Decreased fetal urinary output
Decreased AFV
Decreased FM
When fetal blood flow is compromised, umbilical vein flow is:
Increased
Reversed blood flow in the IVC may indicate:
Right ventricular failure
Most common type of twinning:
Dizygotic
Cord entanglement is most likely to occur in:
Monoamniotic, monochorionic
Twin to twin transfusion syndrome occurs only in:
Monochorionic twins
In twin to twin transfusion syndrome, the donor twin or “stuck” twin becomes stuck as a result of:
Oligo
Most common type of conjoined twinning:
Thoracopagus
Discordant growth in twins may be indicated by an abdominal circumference greater than:
20 mm
Macrosomic fetuses may be found in women with what kind of Diabetes:
Diabetes type 1,2 A and B
Describe symptoms of preeclampsia:
Albuminuria
Headaches
Edema Of the LE
Hypertension of 140/90 or higher
With each pregnancy, Rh sensitivity may:
Increase
What test is done on the amniotic fluid to check for bilirubin
Delta OD 450
Where is the blood injected while performing fetal blood transfusion?
Peritoneal cavity or umbilical vein
Ossification centers in the femur are usually seen by:
32-33 weeks
Best area to Doppler umbilical cord
In the mid portion
Doppler flow characteristics of umbilical vein:
Constant low velocity flow
Normal umbilical vein flow:
100-120 ml/kg per minute
Significant protrusion of the membranes is considered when they bulge:
6 mm or greater
4mm would be funneling of cx
Complications associated with transnational sonography in the 2nd and 3rd trimester
Amnionitis
Stimulation of uterine contractions
Vaginal bleeding
Lower limit for a normal cervical length on a transabdominal scan is:
3cm
Second most important cause of perinatal mortality is:
Preterm labor
Most common cause of 1st trimester spontaneous abortion is:
Fetal chromosomal anomalies
The overlapping of the fetal cranial structures is referred to as:
Spaulding’s sign
