Each had gastric ultrasound (gUS) to verify empty stomach prior to ingestion of 125 g of yogurt within 5 min. For the epidural group, the meal was consumed within one hour of epidural placement. Serial gUS was performed at 15, 60, 90, and 120 minutes thereafter and fraction of gastric emptying was calculated as [Area_Antral_90 / Area_Antral_15 - 1]*100. || 10 pregnant women at term, 10 non-pregnant women, and 10 parturiants with no labor epidural. || Gastric emptying fraction (higher is better) was 52% (non-pregnant), 45% (pregnant), 7% (parturiants w/o epidural), and 31% (parturiants w/ epidural). Parturiants had delayed gastric emptying compared to non-parturiants, and epidural analgesia actually sped up gastric emptying.
