Participants
A cohort of 56, 10- to 16-year-old, CDH survivors was identified from the medical records at the Hospital for Sick Children in Toronto, ON, Canada; this represented the entire cohort of survivors born during a 6-year period. At the time these individuals were born, our institution used high-frequency oscillating ventilation as a rescue therapy [13]. Although ECMO was available, it was considered a treatment of last resort restricted to babies who were not expected to survive without such
Medical histories
To ascertain whether the participating CDH survivors were representative of our entire cohort of survivors, we extracted information from the medical records for all survivors regarding: gestational age; Apgar scores (1 and 5 minutes); side/size of hernia; need for surgical patch; highest preoperative and postoperative pH and CO2; length of time/type of ventilation; use of alkalinization therapy, steroids, and muscle paralysis agents; presence/severity of chronic lung disease; duration of
Discussion
Short-term neurodevelopmental outcomes of non–ECMO-treated CDH survivors are considered to be quite good, with low rates of developmental issues being reported in preschoolers [4], [6], [10]. As CDH survivors move through their school-age years, however, neurodevelopmental weaknesses become more apparent. In our study, between 23% and 46% of non–ECMO-treated CDH survivors tested in late childhood and adolescence demonstrated clinically significant academic difficulties on standardized
Conclusion
The findings described here may prove useful in guiding prospective research with CDH patients. They also contribute to our understanding of the effects of hypocapnia or hyperventilation on the developing brain and highlight the need to follow older cohorts of CDH survivors who appear to be at substantial risk for neurodevelopmental problems. Health care professionals need to be aware of these problems so that they can counsel families antenatally and help parents plan prospectively for their
