When the tube causes gagging, bend forward and sip water or ice chips. The tube is advanced through the esophagus and stomach to the duodenum. I.V. glucagon is started or an intramuscular injection of an anti-cholinergic drug is given. Barium is passed into the duodenum through the catheter. X-ray spot films are made.
Some barium is withdrawn.
Air is passed through the catheter. Additional spot films are taken. You may be asked to wait a short while until films are developed. Rest in a waiting area until someone can take you home. A laxative to relieve constipation may be given.
