Fetal Heartbeat Monitoring

Question 1

1. Variable deceleration: Cause
2. Normal FHR, Variablity
3. Continuous monitoring significantly increase the risk of the following: (a) perinatal death rate (b) The rate of C/S (c) The rate of Cerebral palsy (d) The rate of instrumental delivery
4. Fetal ABG: Aciditic pH value, Association with APGAR score, Caution
5. Fetal Pulse Ox: Abnormal value, useful instance
6. Fetal lung maturity: (a) normal for normal pregnancy, diabetes (b) Saturated phosphotidylglycerol for normal and diabetes (c) TDx-FLM

Answer 1

1. Umbilical cord compression
2. 110-160 bpm, 5-25 bpm
3. (b), (d)
4. pH<7.2, Well correlated, Maternal acidosis (Fetal demise start with resp acidosis then metabolic acidosis)
5. <30%, decrease C/S for non-reassuring fetal status.
6. (a) >2.0, >3.5 (b) >500, >1000 (c) <40 immature, >50 mature (no adjustment for diabetes)
