Sixty-six of 390 patients studied at LAC/USC Women's Hospital between 1970 and 1973 had positive oxytocin challenge tests (OCT). Tnenty-four percent of patients who were allowed direct monitored labor after a positive OCT showed no late deceleration and must be assumed to have had false-positive tests. Patients with positive OCT's had significantly increased incidences of perinatal mortality, infants with low Apgar scores, infants with IUCR, abnormal estriol excretion, and late deceleration in labor when compared to patients with no positive OCT. The combination of a positive OCT and abnormal 24-hour uninary estriol excretion should be considered ominous.
