Induction of labor with prostaglandin E2 vaginal tablets in parous and grandmultiparous patients with previous cesarean section.
OBJECTIVE
To compare the outcome of induction of labor with prostaglandin E2 vaginal tablets between lower parity (parity 1-5) and grandmultiparous (parity >5) patients with a history of one previous lower segment cesarean section.


METHODS
A prospective study of 113 patients conducted at King Faisal Military Hospital, Khamis Mushayt, Saudi Arabia during a 5-year period spanning January 1995 to December 1999.


RESULTS
There were no statistically significant differences in the two groups regarding mean maternal age, dose of prostaglandin used, gestation at delivery, mean birth weight, P>0.05. Syntocinon augmentation was used in 16 (21.9%) of the lower parity patients compared with 8 (20.0%) in the grandmultiparas but this was not statistically significant, (P=0.677). However, there was a statistically significant difference in the cesarean section rate between the two groups, P=0.019. Although no cases of uterine hyperstimulation were recorded, there was one rupture of the uterus in each of the two groups of patients; 1.36% and 2.5%, respectively, but this was not statistically significant, P=1.000.


CONCLUSIONS
The complications of induction of labor with prostaglandin E2 vaginal tablets in grandmultiparous patients with previous cesarean section were similar to those with lower parity but the cesarean section rate was significantly higher. However, larger studies are needed for validation.
