Causes
1 2 3 4 |
Uterine
Placental Umbilical Cord Maternal, i.e. hypotension |
|
|
Chronic Fetal Distress:
Dx and Causes |
SFH and Weight gain
U/S Causes: hypertension, smoking, nutrition, chromosomal etc |
|
|
Acute Fetal Distress
Causes |
Abruption
Infection Cord accident Preeclampsia |
|
|
Antepartum Tests for Fetal Wellbeing
|
SFH
Weight gain MSS U/S / BPP NST Contraction test (give oxytocin at term; if HR drops, consider delivery) |
|
|
SFH Scores
20-32 weeks? 32-40 weeks? |
20-32: equals GA
32-40: add 2 to get GA |
|
|
BPP
What information does it give? 4 elements? |
+ve score = reassuring
-ve = not reassuring Movement, tone, breathing, AFV (NST) |
|
|
NST
What is reassuring? |
2 accelerations of 15 / ming lasting 15 seconds, usually associated with movement
Absence of decelerations |
|
|
Decelerations
Early: Variable: Late: Bradycardia: |
Early: Head compression due to contractions. Normal
Variable: Cord compression Late: Uteroplacental insufficiency Bradycardia: sustained deceleration (often with epidural-- complications rare) |
|
|
Tx Decelerations?
|
Stop oxytocin
IV bolus Oxygen Maternal left side Pelvic: for prolapse Try to stall vag delivery...C/S |

|
OCT
|
Stimulate 3 contractions in 10 min; look for decelerations
Not often done due to high FPs-- BPP has replaced it |
|
|
How do you measure intrapartum wellbeing of fetus?
|
Maternal temp / HR
FHR Meconium Scalp pH |
|
|
Scalp pH Cutoffs
|
< 7.20 = Deliver!
7.2-7.25: deliver in 20-30min 7.25-7.35: normal |
