Predictability of intrapartum cardiotocography with meconium stained liquor and its correlation with perinatal...

To determine the relationship between the colour of liquor and the trace of cardiotocography to see whether it is reactive or non-reactive..

This cross-sectional study was conducted at Obstetrics and Gynaecology department, Dar-ul-Sehat Hospital, Karachi from June 2015 to March 2016, and comprised women in labour who delivered singleton babies and had >37 weeks of gestation. Intrapartum monitoring by cardiotocography was conducted. The status of the amniotic membranes, colour and amount of liquor observed were recorded. Cardiotocography was performed for 30 minutes in the left lateral position on admission as well as a monitoring tool in labour at an interval of less than 4 hours. Foetal heart transducer and uterine pressure transducers were applied and the readings were recorded. SPSS 21 was used for statistical analysis.

Of the total 200 subjects, 183(91.5%) were reactive and 17(8.5%) were non-reactive women. Overall mean age was 27.39±4.40 years. Most commonly noted risk factor were post-date 53(26.5%), anaemia 35(17.5%), premature rupture of membranes 28(14%) and pregnancy-induced hypertension 10(5%). Insignificant difference was observed in between Cardiotocography findings and risk factors of the women (p>0.05)..

Significant change was seen in cardiotocography of clear liquor which needs more evaluation to rule out ongoing hypoxia.
