نبذة مختصرة : PURPOSE: Congenital myotonic dystrophy (CDM) results in hypotonia and acute respiratory distress at birth. Previous studies show that prolonged periods of intubation (>4 weeks) correlate with increased mortality rates. The objective is to describe the use and duration of respiratory support in newborns with CDM and how these relate to mortality. METHODS: A retrospective chart review was performed at a tertiary pediatric hospital among children with confirmed diagnosis of CDM. The main outcome measures were: mortality, duration of invasive mechanical ventilation (IMV) and non-invasive partial pressure ventilation (NIPPV), along with long-term use of respiratory support and equipment. RESULTS: A total of 18 subjects met inclusion criteria, 83%.f which had documented respiratory distress at birth, 39%.equired NIPPV, and 50%.equired intubation in the neonatal period. The earliest NIPPV was initiated at day one of life, and the latest extubation to NIPPV was at 17 days of life. CONCLUSION: This cohort required IMV for shorter periods with earlier transitions to NIPPV which suggests a possible change in practice and earlier transition to NIPPV recently. Further data are needed to determine if there is a possible correlation between the need for NIPPV/IMV and mortality rates.
