Two sets of group of 50 women were examined and compared to find out if the introduction of continuous intra-uterine catheter during labour increased infection. Amniotic fluid was withdrawn from both groups and examined. Also a catheter was introduced into the amniotic sac of one group and after 2 and 5 hours amniotic fluid was also withdrawn from both groups and examined. Inhaled amniotic fluid from the infant was also withdrawn and bacteriologically examined both quantitatively and qualitatively. The examination proved that there was no significant increase in the infection of the test group and the control group. Also there were no complications observed on the mother and child after delivery.
