Cervical dilatation threshold of 1 cm/hour throughout labour is unrealistic for most women, regardless of parity.
We already know this but a timely reminder that ALL woman are different and progress should be evaluated contextually and individually. Cervical dilatation patterns for low-risk women are not linear.
The overall labour progression pattern deviates considerably from the classic Friedman's curve that has been central to labour practice for several decades. An important finding across included studies is the wide variability in the distribution of cervical dilatation profiles. Please read the full study here.
