[Value of endogenous uterine contraction stress test by breast nipple stimulation].

In a prospective study we performed a breast-stimulation-test (BST) in 136 patients. Sufficient contractions could be achieved in 89.7%. A hyperstimulation was seen in 5.8% of the patients. We could not find a false negative BST-result. The duration of the BST was significantly shorter compared to the OBT. The new noninvasive method was well accepted by patients and staff-members, leading to a new management of fetal surveillance in patients beyond 40 weeks of pregnancy.
