Objective To investigate the effect of compound Lidocaine Mucilago applied on uterus cervix for labour pain relieving in active period and for speeding up delivery. Methods A total of 250 women with normal pregnancy history were selected and divided randomly into the test and control groups to test effect of labour pain easing during their vaginal deliveries. Those in test group were applied 5ml of compound Lidocaine Mucilago to uterus cervix when uterus os opened to 4cm wide, while no compound Lidocaine Mucilago were given to those in control group. The degrees of labour pain, dilatation of cervical os, and the length of delivery period were recorded and compared between the test and control groups. Results By reference to the established standard, the greater effects of pain easing were observed in 60 min after the application of compound Lidocaine Ointment in test group than checking group (97 60% vs 20 00%, P< 0 005). The active period and the total delivery time of the test group are much shorter than that of the controls ( P< 0 05). Conclusions Application of Compound Lidocaine Mucilago to uterus cervix when uterus os opens to 4 cm wide, is an effective way for labour pain easing. It can also speed up dilatation of cervical os, shor- ten active period of labour and delivery time. No side effects were observed in mother and child. This simple and economic method is worthy to be recommended for routine clinical practices.
