ctg Flashcards
in uncomplicated labour how often should auscultation w/ doppler/pinard stethoscope be performed ? for 1st stage and 2nd stage
1st - every 15 mins
2nd - every 5 mins
how often in maternal pulse felt in 1st stage of labour
every hour
what is CEFM - continuous electronic foetal monitoring a- a screening tool for ?
hypoxia
if there is prolonged decelerations for more than 3 minutes what should be done ?
urgent c section
what is the expected number of contractions in established labour in 10 minutes ?
3-5 contractions every 10 mins (>5 is hyperstimulation)
what should the baseline rate be on a CTG
110-160bpm
what is good variability on a ctg ? what is reduced ? how long would reduced variability be expected to last for if normal?
5-25 per min
<5 is reduced
<40 mins baby may be asleep
if greater than >90 mins may suggest compromise
what is an acceleration
an increase in foetal HR for min 15 beats for 15 seconds
how many accelerations should typically occur in 15 minutes and what do they typically occur along side with?
2 and contractions
what kind of decelerations indicate hypoxia ?
late decelerations
what is a terminal bradycardia
baseline foetal hr drops below 100bpm for more than 10 mins
what is a terminal deceleration
hr drops and does not recover for more than 3 mins
what should you do if terminal bradycardia and terminal decelrations
deliver via c section
if a baby has a suspicious ctg , late decelerations, reduced variability or foetal tachycardia what can be done to investigate
foetal scalp blood sample
what would a sinusoidal ctg indicate and management
severe foeatl hypoxia, foetal anaemia, foetal or mat haemorrhage
urgent c-section required
