neonatal resuscitation week 1 Flashcards
Where does resuscitation start?
in utero
Baseline heart rate is _____ and a decrease may indicate _______.
Baseline heart rate is normally 120-160 bpm and a decrease may indicate asphyxia
Is variability normal?
Yes
The absence of short and long term variability may indicate fetal distress!!!
Short term variability
3-6 bpm; CNS depressants reduce this short-term variability
Long term variability
Characterized by periodic accelerations correlating with fetal movements normally 15-40 accelerations per hour. Decreases seen with fetal sleep.
Early decelerations
Vagal response to head compression, not associated with distress.
Late decelerations
Uteroplacental insufficiency. Decreased O2 supply, combined with lack of short-term variability is ominous for fetal distress.
Variable decelerations
Related to cord compression, associated with fetal asphyxia when they are greater than 70 bpm, longer than 60 sec, or occur in a pattern persisting for more than 30 min.
Where can you get fetal blood sampling from?
Can be obtained via scalp puncture after membranes ruptured.
Normal neonate ABG values
pH 7.25-7.35 normal
7.20-7.25 is borderline
below 7.20 may be associated with neonatal depression
Fetal Scalp Blood Sample Analysis
Normal
pH: 7.25-7.35 (mean 7.33)
pCO2: 40-50 mmHg
pO2: 20-30 mmHg
Base: <10
Metabolic Acidosis
pH: <7.25
pCO2: 45-55 mmHg
pO2: <20 mmHg
Base: >10
Respiratory Acidosis
pH: <7.25
pCO2: >50 mmHg
pO2: Varies
Base: <10
What is the goal of fetal treatment?
Goal should be to restore uteroplacental circulation
Avoid and treat aortocaval compression.
Correct hypotension.
Correct hypoxia.
Failure to remedy the situation calls for immediate delivery.
Methods for neonatal assessment
Fetal Heart Rate Monitoring
Apgar scores
Fetal cord pH
CPR
APGAR scores
Who is primarily responsible for the care of the neonate?
The neonatal care team
