Intraesophageal pressure recording improves the detection of cough during multichannel intraluminal impedance testing (pH-MII) in children

摘要

BackgroundOne of the primary reasons for referral for reflux testing is to correlate reflux events with symptoms such as cough. Adult studies have suggested that symptom recording is flawed and pediatricians feel this is an even more significant problem as there may be errors in both parental and patient report. We hypothesize that intraesophageal pressure recording (IEPR) provides an objective method to identify coughs during reflux testing in children.
