Detailed Description
Healthy volunteers will be solicited (medical students and attending anesthesiologists) to participate in the study. Volunteers will participate in two sessions, one for orange juice without pulp and one for orange juice with pulp. Participants will be NPO after midnight and will be asked to arrive at approximately 8 am. Upon arrival for females of child bearing age, a urine pregnancy test will be performed and they will be discreetly informed of the results of the test. After, all patients will have their gastric volume assessed using point-of-care ultrasound to ensure the study team is able to adequately identify their stomach as well as to ensure the stomach is empty. After measurements are made, participants will drink 12 oz (approximately 350 mL) of either orange juice with or without pulp. Two hours after finishing the juice they will again undergo point-of-care gastric ultrasound scanning. Images will be saved and will be examined by a blinded independent anesthesiologist. The study will entail two visits each lasting for approximately 3 hours.
Point-of-care gastric ultrasound will be performed using a low-frequency curvilinear ultrasound probe. The exam will be performed on a stretcher with the participant in both the supine and right lateral decubitus (RLD) position. The goal of point-of-care gastric ultrasound is to obtain an image of the gastric antrum. The low-frequency large curvilinear probe is placed in the epigastric area in a sagittal or parasagittal plane immediately inferior to the patient's xiphisternum with the orientation marker directed cephalad. Image optimization requires scanning in an anterior and cephalad direction toward the liver by tilting the tail of the probe toward the feet. A qualitative analysis will occur first to rule out solid contents in the stomach. Once confirmed, the gastric antral cross-sectional area (CSA) will be measured in the RLD position. Correlation has been shown between CSA and total gastric fluid volume. A gastric volume less than 1.5 mL/kg is considered consistent with fasting.
The study will be repeated for both orange juice with and without pulp.
