Ultrasound Assessment of Gastric Emptying
Completed
Conditions studied: Pregnancy
In brief
Hypothesis: The volume of gastric contents will be the same for a high protein drink versus ice chips as measured by ultrasound at 20 minute intervals for two hours in the laboring parturient. Specific Aim: To determine the volume of gastric contents at various time intervals (every 20 minutes for 2 hours) in patients with an epidural that are given a high protein drink versus those that are given ice chips, with ultrasound.
