Effect of spasmoanalgetic Dolantin on the electromyographic activity of the cervix during labour.
The influence of spasmoanalgetic Dolantin on electrical activity of the smooth musculature of the cervix during labour was studied in 50 primiparous women after induction of labour. The highest electrical activity was measured at the time of uterine contraction (AC) and between contractions (BC). The basic pattern of Dolantin-produced changes in muscular contractions in the cervix observed via EMG activity is that of the EMG activity diminishing with contractions of the uterine corpus and even more so in the period between contractions. Dolantin administered during the latent phase of induced labour did not accelerate cervical dilatation either in the latent or in the active phase of amniotomy- and Oxytocin-induced labour.
