Study design: The intrapartum fetal oximetry prospective, multicenter, randomized, controlled trial (the FOREMOST trial) was conducted in 4 Australian maternity hospitals. The primary outcome was operative birth rates for nonreassuring fetal status. Results: There was a statistically significant 23% relative risk reduction in operative delivery for nonreassuring fetal status in the fetal pulse oximetry + cardiotocograph group (n = 75 of 305, 25% ), compared with those in the cardiotocograph- only group (n = 95/295, 32% )- (relative risk 0.77, 95% confidence interval 0.599, 0.999, P = .048). There were no significant between- group differences in overall operative births (fetal pulse oximetry + cardiotocograph group 73% , cardiotocograph- only group 71% , relative risk 1.04, 95% confidence interval 0.94, 1.15, P = .478) or neonatal outcomes. Conclusion: The use of fetal pulse oximetry to augment fetal well- being assessment during labor resulted in a statistically significant reduction in the operative intervention for nonreassuring fetal status, compared with the use of conventional cardiotocograph monitoring alone. This reduction was achieved with no significant difference in neonatal outcomes.展开更多
