Main findings
The study has demonstrated that; firstly, MCA-PI and MCA-PI z-score are significant lower in pregnancies that require emergency delivery for pathological CTG during labour compared with those who do not; secondly, the umbilical cord arterial pH significantly correlates with log10 cCTG STV, whilst none of the study parameters correlates with umbilical arterial cord base excess; thirdly, smoking and log10 cCTG STV are independent predictors of umbilical cord arterial pH; fourthly, nulliparity, maternal diabetes and EFW z-score are independent predictors of NICU/SCBU admission; and lastly, none of the factors amongst maternal characteristics, labour onset, indications of labour induction, EFW z-score, maternal-foetal Doppler indices, log10 cCTG STV and Dawes-Redman criteria by cCTG is predictive of emergency delivery due to pathological CTG during labour and umbilical cord arterial pH <7.1.
