A retrospective analysis on the 100 cases cesarean section with indication of cephalopelvic disproportion was carried out in Beijing Obstetrics and Gynecology Hospital, From March to October in 1992, there were 73 cases were performed operation with correct diagnosis and management, another 27 cases were required further discussion, such as too early intervention of the delivery in laten phase in 8 cases, improper observation and management in active phase in 19 cases. Therefore we suggest that the diagnosis of cephalopelvic disproportion should be carefully after observation in labor stage and sufficiently trials of labor. It may decrease the rate of cesarean section and increase the obstetric quality.
