CTG Flashcards
(18 cards)
white
contractions
less than 5 in 10 min
FRH
White
110 - 160
white variability
5-25
white
decelerations
no decels
early decels
variable decels that are not evolving to have concerning characteristics
what are concerning characteristics of variable decelerations
- lasting more than 60 seconds
- reduced variability within the deceleration
- failure or slow return to baseline fetal heart rate
- loss of previously present shouldering
if fetal accelerations are normal then what
fetal acidosis is unlikely
if CTG is suspicious consider:
fetal scalp stimulation
or
expedition of birth
what are conservative measure to consider when suspicious or pathological CTG
- reduce or stop synto
- offer terbutaline
- encourage woman to change position or mobilize , avoid being supine
when to give fluids?
Do not give fluids to teat CTG abnormalities, unless women is hypotensive or has signs of sepsis
amber contractions
5 or more in 10 min
leading to reduced resting time between contractions or hypertonus
red contractions
nil
FHR amber
increase in baseline fetal heart rate of 20 beats a minutes or more from the staRt of labour or since the last review an hour ago OR
100-109 FRH
OR
UNABLE TO DETERMINE BASELINE
FRH red
less than 100 or more than 160

decels red
repetitive variable decels with any concerning characteristic for more than 30 min
or
repetitive late decels for more than 30 min
or
acute bradycardia or a single prolonged deceleration lasting 3 min or more
what is the categorization of CTG
normal
suspicious - 1 amber
pathological - 1 red or 2 amber
