OB: Basic Fetal Heart Monitoring -
NUR252
Basic Fetal Monitoring - ANS-Top of fundal area = toco monitors for uterine contractions
Lower belt = ultrasound tracing fetal heart rate
Normal fetal heart rate - ANS-110-160/min
what does fetal monitoring tell us - ANS-- fetal oxygenation
- acid-base status of the fetus
- prevention of hypoxia/asphyxia
- monitors distress
Consequences of Inutero Hypoxia/Asphyxia: - ANS-- Cerebral Palsy
- Mental Retardation
- Epilepsy
- Respiratory distress syndrome
- Renal Damage (no O2 to kidneys)
- NEC (Necrotizing Enterocolitis) (no O2 to bowels = death/dying)
- Chronic Brain Impairment
toco transducer - ANS-- top devise
- which senses uterine activity
- place above mother umbilicus to the right or left
ultra sound device - ANS-- lower
- senses the fetal heart beat
- ultrasound jelly
** if heart rate is high in the abdomen = breech baby (need to call DR & confirm)
Internal Monitoring: - ANS-- Intrauterine Pressure catheter
- Fetal Scalp Electrode (FSE)
*Intrauterine Pressure catheter* - ANS-- You do not do this (only doctor)
- cervixes needs to be dilated at least 3 cm
- bag of water has to be ruptured
, *Fetal Scalp Electrode* (FSE) - ANS-- Nurses can do this
- Internal fetal heart monitor
- Cervix has to be dilated 3cm
- Bag of water has to be ruptured
*Monitoring Contractions* - ANS-External: Toco transducer
Internal: Intrauterine pressure catheter (IUPC)
*Monitoring Fetal Heart Rate* - ANS-External: Ultrasound device
Internal: Fetal scalp electrode (FSE)
measure intensity of contractions - ANS-*objectively*: IUPC
*subjectively*: palpating funds during contractions
If the fundus tone feels like:
Tip of the nose = mild contraction
Chin = moderate contraction
Forehead = strong contraction
Fetal Heart Monitoring Tracing Paper - ANS-Top: fetal heart rate
Bottom: contractions
fetal monitor paper - ANS-6 squares = 1 minute
1 square = 10 seconds
Counting *duration* of contractions: - ANS-From the beginning to the end of one
contraction (length of contraction)
Counting *frequency* of contractions: - ANS-Beginning of one contraction to the
beginning of the next contraction
contraction *length* - ANS-40-70 secs
>2 minutes = major stress for baby
- can also be caused by Pitocin
- beginning to the end of contraction (length of contraction)
Critical drip: *Pitocin* - ANS-- should always be on a pump
- Pitocin is only a critical drip when baby is on board
