8/26 Lecture Flashcards
What does the acronym of NR FHR mean?
Non reassuring Fetal Heart Rate
What provides oxygen and nutrients to the fetus?
Umbilical vein
What receives CO2 and waste from the fetus?
Umbilical artery
If fetal hypoxia continues what can happen?
Metabolic acidosis
Damage to vital organs
Accumulation of lactic acid can lead to birth asphyxia
Permanent brain damage may result
If the baby has respiratory difficulties, lack of tone, subnormal consciousness, seizures, what do you suspect?
Neonatal encephalopathy
What type of cerebral palsy is associated with AP or IP asphyxia (ACOG say majority IP)
Spastic CP
What type of cerebral palsy is more related to genetics?
Dyskinetic or ataxic CP
What is a FSE?
Fetal scalp electrode
Used to monitor baby pulse rate
What is normal baseline rate for baby?
120-160
What is fetal bardycardia?
80-100 (if persists this is an ominous sign)
What is fetal tachycardia?
Above 160
What is a common reason for fetal tachycardia?
Chorioamnionitis
Chorion faces who?
Mom
Amnion faces who?
Baby
What are 2 common side effects of epidurals?
Fevers can lead to tachy in the baby
maternal hypotension
What is gentamycin toxic to?
The kidneys
Why is heart rate variability important?
shows that there is both parasympathetic and sympathetic control
Moderate variability (adequate oxygenation) is variability of how many bpms?
6-25 bpms
What is marked variability?
> 25 bpm
What is nonreassuring FHR variability?
Absent
What is minimal feta heart rate variability (concerning, or baby could be asleep)
<6 bpm
What is early decelerations?
Occurs early with UCs. can be due to head compressions, physiologic
If late declarations are persistent, what do you want to think?
Uteroplacental insufficiency (which can lead to fetal hypoxia)
What do variable deceleration indicate usually?
Umbilical cord compression
How many babies are born with a cord around their neck?
1/3 of babies
If there are persistent and deep FHR changes what can be done?
Amniofusion may relieve cord compression
