title: [The effect of the duration of administration of epidural analgesia on delivery].
abstract: The authors compared the length of labour periods, number of surgical deliveries, the use of oxytocin, analgetics, spasmolytics and intensity of pain in two groups of primiparae, who were in labor under continuous epidural analgesia (CEA). In the first group CEA was started when the cervix was dilated not more than 3 cm, in the second one when the cervix was dilated more than 3 cm. The length of labour, oxytocin consumption and frequency of vaginal surgery did not differ in the two groups. In the first group there was great consumption of analgetics and spasmolytics, more motor blocks of the lower extremities and a higher rate of Caesarean sections on account of dystocia. In some of the women of the first group the intensity of pain at the end of the first stage of labour and during the second stage was higher than before the onset of CEA.
  
  
  CONCLUSIONS
  It seems to be better to start CEA when the cervix is dilated more than 3 cm.
