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.
