Get immediate access, anytime, anywhere. In the first stage of labor, the diagnosis of dystocia can not be made unless the active phase of labor and adequate uterine contractile forces have been present. Most commonly, size discrepancy secondary to fetal macrosomia is associated with difficult shoulder delivery.

See My Options close. Fetal anomalies such as hydrocephaly, encephalocele, and soft tissue tumors may obstruct labor.

Ressel Am Fam Physician. Beta-blockers are generally considered to be safe, although they may impair fetal growth when used early in pregnancy, particularly atenolol. The dystocla of oxytocin administration is to stimulate uterine activity that is sufficient to produce cervical change and augmentatiob descent while avoiding uterine dysstocia and dysrocia compromise.

The active phase of labor is characterized by an increased rate of cervical dilation and by descent of the presenting fetal part. If oxytocin is being infused, it should be discontinued to achieve a reassuring fetal heart rate pattern.

The duration of the second stage of labor is unrelated to perinatal outcome in the absence of a nonreassuring fetal heart rate pattern as long as progress occurs.
