To investigate the effect of dolantin on fetus and uterine contraction. Thirty pregnant women under stress, restless or fatigue were given dolantin 100 mg i.m. during the latent phase of labor. Internal fetal heart rate (FHR) monitoring and intrauterine pressure measuring were carried out at 30 minutes, 1 hour and 2 hours after medication. The baseline FHR showed a decrease 30 minutes after dolantin, and decreased further at 1 and 2 hours though still within normal range. At the same time, the baseline of intrauterine pressure decreased as well at 30 minutes, so hypertonic uterine contractions were improved. One hour later the incoordinate uterine contraction was relieved and the frequency and strength of uterine contraction were enhanced (P < 0.01). During labor, especially in latent phase, the use of dolantin may improve the general condition of the women. In spite of the decrease of FHR, no fetal distress occurred. Besides, it may enhance the frequency and strength of uterine contraction and relieve the incoordinate uterine contraction.
