Filter by:All neonates, ages 0 to 4 months, presenting to LPCH pediatric ENT clinic for airway difficulties or stridor will be screened for inclusion. As is consistent with an acceptable standard of medical care, these children will undergo a flexible nasal endoscopic exam to make the diagnosis of laryngomalacia, as well as be weighed and a breastfeeding history taken. If laryngomalacia is present, the study staff with then administer the Infant Gastroesophageal Reflux Questionnaire (IGERQ) and an airway symptoms questionnaire (ASQ). Those babies with an IGERQ score of less than sixteen (no more than mild reflux) and an ASQ score greater than six will be eligible for randomization. The patient will then be randomly placed in the control group (placebo) or the intervention group (ranitidine 2mg/kg every 12 hours or famotidine 0.5 mg/kg daily). Patients will stay on medication for a minimum of 6 months, or until symptoms resolve. Patients will be seen in follow up at 1, 2, 3, 4, 5, 6, 8 and 10 months. At which time I-GERQ, ASQ and weights will be taken. The primary outcome measure will be the time for the ASQ score to drop to normal on ranitidine or famotidine versus placebo. A secondary outcome will be weight gain in percentile. If the patient's I-GERQ score goes above 16 at any time in the study, the patient will be crossed over to the treatment arm and started on medical treatment.
Noisy breathing is commonly caused by a floppy voicebox which is a condition called laryngomalacia. The cause of laryngomalacia is not fully understood, but some studies have suggested that it could be due to acid escaping from the stomach and spreading up the swallowing passage to the throat (acid reflux). This affects about 1 in 100 newborns and is therefore one of the most common reasons for infants to see Otolaryngologists at BC Children's Hospital (BCCH). These infants can have a spectrum of distressing symptoms including squeaky breathing, choking, difficulty feeding, failure to gain weight, and episodes of turning blue (due to lack of oxygen). At present, Otolaryngologists at BCCH will sometimes give children with laryngomalacia medication to reduce the amount of acid they make in their stomachs, in the hope that this will reduce their symptoms of laryngomalacia. It has never been scientifically confirmed whether anti-reflux medication will benefit these children any more than doing nothing at all.
