Explanation
Question 10 A 34 year old primigravida presents in spontaneous labour at 39 weeks gestation. The cervix is 4cm dilated with thin meconium stained liquor. The CTG over 25 minutes shows a base-line fetal heart rate of 135bpm with variability of 3-4bpm, no accelerations and variable decelerations. There are 3-4 uterine contractions every 10 minutes.
(Correct answer: F)
EXPLANATION GIVEN-
NICE guidlines--2 non reasuring features (low variability and variable decelerations)= pathological CTG.FBS or delivery.at 4cm FBS possible.
NICE guidline-Non Reasuuring Features include variability reduced for 40-90 minutes and variable decelrations with over 50% of contractions occuring for over 90 minutes.
This CTG is for 25minutes,does it still qualify as pathological?
Thanks Paul.
u misunderstand
Posted by Stanley T.
poor btbv more than 90 minutes pathological but that is without variable deceleration
throw in a variable deceleration in the poor btbv and it become pathological immediately no time frame here

Thanks a lot for ur reply Stanley,i was pretty sure i am not going to get one before my exam on 11th.
i am still confused,if variabilty is reduced for 25 mins or
variable decelrations r present fr less than 90 mins do they qualify as non reassuring features as a definite time frame is given by guidline?
secondly is there no time frame required whenever two features occur together to classify them as nonreassuring or abnormal ?
please reply as soon as possible as i have a few days left before exam.
