MIDWIFERY STRATEGIES FOR LIABILITY RISK REDUCTION
POSTDATES PREGNANCY/POST MATURITY

Definition: A postdates pregnancy is one that continues beyond the completion of 42 weeks or 294 days of gestation (from the first day of the LMP), based on reliable dates.

The etiology of postdates delivery is largely unknown. Predisposing factors may include anencephaly. The major complications for the postdates infant may include postmaturity syndrome, intrauterine growth restriction (IUGR), meconium aspiration, intrauterine hypoxia or asphyxia, fetal distress, fetal demise, oligohydramnios, macrosomia, and shoulder dystocia. The maternal complications may include increased incidence of dysfunctional labor, operative delivery, pelvic trauma, hemorrhage, and infection.
