Abstrakt		General objectives: To contribute to a broader understanding of the activity of the human uterine cervix during pregnancy and at the onset of labour. By analysing electromuographic (EMG) recordings of cervical smooth muscle activity, we aimed to further characterise EMG activity at the onset of induced labour. The EMG signals are supposed to reflect the actual activity of the cervical smooth muscle tissue and, thus, its readiness (ripeness) for parturition. Besides the well-established Bishop pelvic score, EMG recordings could be used as an additional tool for evaluating pelvic condition, thereby helping the obstetrician to predict the course of labour and undertake appropriate procedures. Immediate objectives: To improve the processing of signals from cervical EMG activity and to characterise the pattern of the activity at the onset of labour with regard to various components constituting the Bishop pelvic score. Main hypothesis: Some parameters of the EMG signals, obtained from cervical smooth muscle, are related to individual components of Bishop pelvic score, and have a predictive value for the course of labour. Setting: Department of Obstetrics and Gynaecology, University Medical Centre, Ljubljana. Subjects: Forty-seven healthy primiparous women with induced labour. Methods: The EMG activity of cervical smooth muscle, detected on the exterior wall of the cervix, was registered during the total duration of labour in 47 women by using small spiral steel electrodes. The differential detecting technique was used and signals were amplified 2000 times. Additionally, intrauterine pressure (IUP) was measured by an open-end catheter. Both signals were sampled at 20Hz (18.2Hz) and the data were written to a personal computer hard disk for later processing. For the purpose of this study, a 20-minute interval was selected out of each labour, starting as close to the onset of labour as possible. (Abstract truncated at 2000 characters).
