[Effect of elevated head position in bed in therapy of gastroesophageal reflux]

In a randomized multicentric trial the effect of sleeping with the bed-head raised was studied in inpatients with reflux symptoms. All patients underwent an endoscopic and pH-metric examination. As a result from the diagnostic procedures three groups were formed: group 1 - refluxlike dyspepsia (endoscopic and pH-metric examination normal), group 2 - reflux disease without esophagitis (endoscopy normal, pH-metric examination abnormal), group 3 - refluxesophagitis (endoscopy abnormal). All patients were randomly assigned to either sleeping with horizontal bed-head or having the bed-head raised (15 cm). Furthermore, the patients in group 3 were put on treatment with omeprazole (20 mg twice a day) those in group 2 were treated with a procinetic drug (cisapride 30 mg). The patients in group 1 had no drug therapy. However, antacids were allowed in all patients. For a two-week-period reflux symptoms and use of antacids were registered. No difference was seen in the symptom-score or use of antacids. Also sub-group analysis (sex, age, body-mass-index, severity of esophagitis and nocturnal reflux) did not reveal any impact of sleeping with the bed-head raised on reflux symptoms or use of antacids.
