The average second stage of labor length in the group with disturbed patterns was 25 minutes shorter than the other group. Statistically, this difference was significant (P < 0/00 I). The average for the three stage labor length between the two groups was nut significant (P > 0.05).The results also showed that the chance of cesarean section among the disturbed group was 2.7 times more than the other group (CI= 0/83 - 8/5 , RR = 2/7 ) .
