• ABSTRACT The use of maternal epidural analgesia in labor may be associated with nonreassuring fetal heart rate (FHR) patterns. Fetal oxygen saturation (FSpO 2 ) monitoring may improve assessment of fetal well-being during this time. Mean FSpO 2 values were compared over seven 5-minute epochs: 5 minutes prior to an epidural event (combined insertion of epidural/top-up epidural analgesia and infusion pump bolus), to 30 minutes following the event, including possible effects of maternal position and FHR pattern on FSpO 2 values. Mean FSpO 2 values were significantly different between the 5 minutes prior (49.5%) versus 16-20 minutes (44.3%, P <0.05), 21-25 minutes (43%, P <0.01), and 26-30 minutes (43.8%, P <0.05) epochs; and 6-10 minutes (48.3%) versus 21-25 minutes (43%, P <0.05) epochs, but were not influenced by FHR pattern or maternal position. There were no differences in mean FSpO 2 values following administration of an epidural infusion bolus. We conclude that fetal oxygenation was affected following initial or top-up epidural analgesia and that fetal intrapartum pulse oximetry may be useful in assessing fetal status following these events.
