[24-hour esophageal pH in children].

Continuous 24-hour esophageal pH-monitoring was performed in 89 infants. Of 38 patients with respiratory symptoms 74% were found to have a pathological 24-h pH monitoring. The same number of pathological monitorings (71%) were found in 38 patients with clinical symptoms of gastro-oesophageal reflux. We found pathological monitorings in only 25% of eight patients with unusual posturing and five healthy children all had normal monitorings. Gastrooesophageal reflux is common in children with clinical gastrointestinal symptoms as well as in children with respiratory symptoms.
