A cervimeter for continuous measurement of cervical dilatation in labour-preliminary results.
We briefly review instruments that have been used to measure cervical dilatation and describe the development of a new cervimeter. Curves derived from cervical dilatation and intrauterine pressure traces are presented in a form that clearly records the activity of the uterus and the response of the cervix to individual contractions. Our results suggest a new concept for behaviour of the cervix in labour.
