what the risks are --> esophageal manometry, esophageal motility studies, esophageal function studies, esophageal manometry, test to measure the motor action, the lower esophageal sphincter, les, esophageal body, a catheter, measure esophageal pressure, records the duration, sequence of contractions, in the esophagus, a thin tube is passed, mouth, nose, into stomach, tube is pulled slowly back, esophagus, pressure measurements taken at intervals, along the tube, outer end, the tube is attached to an instrument, a transducer, record the pressure, transducer records the high pressure zone, the lower esophageal sphincter, les, sphincter muscle that acts, a valve, prevent reflux of gastric acid, esophagus, tube, in the esophagus, swallow, swallowing wave, recorded, tube is in place, studies of esophagus done, tube is removed, tests, completed, should not consume any food, fluid, 8 hours, the procedure, infants, children, test depends on child's age, level of trust, prepare child, infant test/procedure preparation, birth to 1 year, toddler test/procedure preparation, 1 to 3 years, preschooler test/procedure preparation, 3 to 6 years, schoolage test/procedure preparation, 6 to 12 years, adolescent test/procedure preparation, 12 to 18 years, experience a gagging sensation, the tube is inserted, purpose of esophageal manometry, measure les pressure, evaluate esophageal contractions, in the evaluation of swallowing disorders, les pressure is normal, relaxes, a swallow, pattern of muscle contractions is systematic, coordinated, a swallow, abnormal results, indicate the following, achalasia, a failure of les relaxation, causing the esophagus to, become dilated, filled, retained food, diffuse esophageal spasm, lack of muscle coordination, request that this test be performed, have gastroesophageal reflux disease, gerd, presence, the tube, in the esophagus, increased salivation, increasing the risk, aspiration, aspiration involves saliva, gastric acid inhaled, lungs instead of swallowed properly, lead to lung injury, aspiration pneumonia, swallowing difficulty, at higher risk, aspiration.
