Objectives. Cough, pain, and desaturation episodes in infants are often ascribed to gastroesophageal reflux, and many are empirically treated with acid suppression medications. The authors hypothesize that most of these symptoms are not related to gastroesophageal reflux. Methods. Retrospective review of 186 combined pH-multichannel intraluminal impedance studies performed in infants at Cincinnati Children's Hospital. Results. Of 4159 symptoms reported 1504 (36%) were associated with reflux events (27% nonacid and 9% acid). When total number of symptoms and reflux events were taken into consideration, nonacid reflux events were as likely to be associated with a symptom as acid reflux events (P = .66). Conclusion. The extra-esophageal symptoms commonly attributed to gastroesophageal reflux in infants are most often not associated with a reflux event. Even though causality cannot be definitively proven, in the minority in whom a symptom association is observed, nonacid events are as likely as acid events to cause symptoms.
