Objective

To evaluate the mode of delivery and maternal morbidity associated with pregnancies ending at 41聽weeks.

Material and methods

We designed a retrospective cohort study. The mode of delivery and maternal complications of 230聽pregnancies ending at 41聽weeks were compared with those in 234聽pregnancies ending between 37 and 40 weeks at the Miguel Servet University Hospital in 2005.

Results

Women delivering at 41 weeks had an increased risk of membrane sweep, unfavorable Bishop score at admission, induction and longer duration of labor. These increases were also seen in the rates of operative vaginal delivery (25.6 vs 17.6%, p < 0.001) and cesarean section (21.7 vs 8.5%, p < 0.001).

Conclusions

The rates of maternal peripartum complications increase as pregnancy reaches 41聽weeks. Accurate investigation of these rates is important to determine the gestational age at which the risk of continuing the pregnancy outweighs the risk of labor induction.
