Clinical research was made to clarify the effect of the continuous epidural analgesia on labor in 50 cases of uncomplicated pregnancies in comparison with 50 cases of control group who did not undergo analgesia during labor at the Department of Obstetrics and Gynecology from January to August, 1978. The results were as follows: 1. In the control group, 26 women were primipara and 24 women were multipara, while 30 women were primipara and 20 women were multipara who underwent labor and delivery under epidural analgesia. The most common maternal age ranged from 26 to 30 in both groups. 2. Duration of the first stage of labor was measured subdividely according to the extent of cervical dilatation, which revealed shortening of labor in primipara under epidural anesthesia. It took 460±36.18 minutes until cervix dilated to 5cm and 165±19.67 minutes over 5cm to full dilatation in the control primipara. It was 480±32.43 and 158±18.39 minutes in primipara under epidural anesthesia, respectively. In the multipara, it took 228.8±23.46 minutes and 77.5±13.24 minutes in the control group and 216.3±24.17 and 104±14.31 minutes in the anesthesized group. 3. Duration of the second stage of labor was lengthened in anesthetic group. While it took 48.0±4.62 minutes in the control primipara and 96.2±13.15 minutes in the women under anesthesia, it was 20.1±1.79 minutes in the control multipara and 54.8±3.73 minutes in the multipara under the epidural anesthesia. 4. Subjective and objective scoring were applied to evaluate the extent of pain relief in anesthetic group: 42 women(84.0%) had good score(0-4), 7(14.0%) fair score(5-8) and only one(2.0%) poor score(9-12). 5. Fetal distress occured in 2 cases in control group and 1 case in the anesthetic group. 47 and 48 cases had good 1 minutes Apgar score(7-10) in control group and anesthetic group, respectively. 49 cases of the control group and all cases of anesthetic group had 5 minutes Apgar score over 7, which showed no significant adverse effects of epidural
