Hypothesis:
Carbon dioxide gas use for endoscopic insufflation is safe and results in less abdominal
distension and discomfort; it is equally effective as air in pediatric patients undergoing
endoscopic procedures.
Aim 1:
Determine the occurrence and severity of abdominal discomfort and distension associated with
endoscopic procedures at baseline, upon awakening from anesthesia, at discharge and at 4
hours after discharge in carbon dioxide group when compared to the air group.
Aim 2:
Determine if the expertise level of the endoscopist contributes to abdominal discomfort and
distension following endoscopy, and whether this differs in the carbon dioxide group versus
air group.
Aim 3:
Determine if carbon dioxide is as effective as air for insufflation.
