Diagnostic Studies

The decision for forceps delivery is often made in the second stage of labor when transport of the mother to other units is not practical and imaging studies may not be available quickly enough. Although x-ray pelvimetry and pelvic magnetic resonance imaging and computed tomography have been shown to help in defining the pelvic anatomy, their usefulness has not been demonstrated in predicting successful vaginal delivery.

Ultrasonographic evaluation of the fetus may be of value in gathering information prior to a forceps delivery, although it is not required prior to forceps-assisted delivery. Ultrasonography can be used to estimate fetal size as well as to assess the position of the fetal head.

No specific laboratory test is used prior to forceps delivery.

In general, evaluation of the patient for forceps delivery is purely clinical.
