Oxytocin challenge test: achieving the desired goals.
The desired goals of the oxytocin challenge test (OCT) are preventing stillbirth and avoiding unnecessary premature intervention. To effectively reduce stillbirth the test should be done on a significant proportion of those fetuses who would subsequently succumb in utero. To analyze whether or not the OCT is achieving these goals. 5351 deliveries over a 2-year period at the University of California, Irvine, Medical Center were studied retrospectively. Four hundred and thirty of these patients had 823 OCTs performed. There were ten positive and 19 suspicious tests, and five neonatal deaths in these two groups. In patients who were studied with OCTs only one stillbirth occurred (in a patient who was noncompliant). During the same period, all stillbirths were reviewed. In the group in which stillbirth occurred, it was determined that 11 or 35% of the patients had indications for antepartum testing but were not tested. All 11 of these patients were transferred to the University hospital or had no prenatal care. It is suggested that these stillbirths may have been prevented had appropriate prenatal care allowed identification of patients for antepartum testing.
