[Clinical study on chanlibao in accelerating second stage of labor].
OBJECTIVE
To find out a new way to strengthen the uterine contraction and shorten the second stage of labor, for improving the prognosis of mother and newborn.


METHODS
Primiparae observed were divided into three groups randomly and Chanlibao (CLB, a preparation of Chinese herbal medicine) or oxytocin (OTC) was given to the CLB group (80 cases) and the OTC group (52 cases) respectively, to the third group, as a control group (29 cases) of natural labor, without any drug was given. Time of second stage of labor (TSL) and prognosis of mother and newborn of different groups were observed and compared. And intrauterine pressure (IP) and fetal heart rate were monitored by means of electronic-monitor.


RESULTS
TSL and postpartum hemorrhage in the CLB group were less than those in the control group. The average IP in former was higher than that in latter, but with no difference as compared with the OTC group. No side effect of CLB was found.


CONCLUSIONS
CLB could obviously strengthen uterine contraction and shorten the TSL, it is cheap, convenient and with no side-effect, so it is a new safe, effective method for improving prognosis of primiparae and newborn, especially for those nonindicated in using oxytocine or infusion of fluid profusely.
