Objective: To reduce bilateral delayed-onset progressive sensory permanent hearing loss using a systems-wide quality improvement project with adherence to best practice for the administration of furosemide.
Design: Prospective cohort study with regular audiologic follow-up assessment of survivors both before and after a 2007-2008 quality improvement practice change.
Setting: The referral center in Western Canada for complex cardiac surgery, with comprehensive multidisciplinary follow-up by the Complex Pediatric Therapies Follow-up Program.
Objectives: To estimate the prevalence of childhood permanent hearing loss (PHL) after early cardiac surgery.
Study Design: This prospective observational (1996-2015) study after complex cardiac surgery with cardiopulmonary bypass at ≤6 weeks of life reports audiology follow-up by registered pediatric-experienced audiologists at 6-8 months postsurgery, age 2 years, and as required throughout and thereafter to complete diagnoses. PHL at any frequency (500-4000 Hz) is defined as responses of >25-decibel hearing level in either ear.
Background: Bilateral sensory permanent hearing loss (PHL) has been reported after neonatal respiratory failure but has rarely been noted in survivors after cardiac operations. We report the prevalence and severity of PHL after Norwood right ventricular-pulmonary artery shunt for hypoplastic left heart syndrome (HLHS), document progressive loss, and explore markers of acute illness and ototoxic medications for PHL.
Methods: This interprovincial longitudinal outcome study after neonatal complex cardiac operations at Stollery Children's Hospital, Edmonton, Alberta, Canada, 2002 to 2007, completed repeated diagnostic audiologic assessments for all survivors by registered pediatric-experienced audiologists.
