Hypothesis: The investigators hypothesize that more than 50% of the patients receiving enteric contrast material (ECM) \< 2 hours of anesthesia/sedation would have residual gastric fluid volume (GFV) \> 0.4 ml/kg. The investigators also hypothesize that measuring GFV by using region of interest in the CT technique is accurate compared to blind aspiration of the gastric contents with a syringe and a multi-orificed orogastric tube.
The purpose of our study is to examine the residual gastric fluid volume when oral contrast is administered within 2 hours of anesthesia /sedation and to validate the accuracy of measuring the residual gastric volume by using region of interest in the CT image by using blind aspiration of the gastric contents with a syringe and a multi-orificed orogastric tube.

76
Cincinnati Children's Hospital Medical Center
Cincinnati, Ohio, United States
Residual gastric fluid volume (GFV) < 0.4ml/kg or > 0.4 ml/kg
Patients will have gastric volume suctioned and measured after the CT scan. The investigator will compare the amount suctioned to the measurement from the actual CT scan when all patients have been enrolled in the study.
Time frame: Approximately 2 hours
Residual gastric fluid volume (GFV) < 0.8 ml/kg or > 0.8 ml/kg
Patients will have gastric volume suctioned and measured after the CT scan. The investigator will compare the amount suctioned to the measurement from the actual CT scan when all patients have been enrolled in the study.
Time frame: Approximate 2 hours
