Abstract

Objective: To evaluate lung function and respiratory morbidity prospectively during the first year of life in patients with congenital diaphragmatic hernia and to study the effect of extracorporeal membrane oxygenation therapy. Design: Prospective longitudinal cohort study. Setting: Outpatient clinic of a tertiary-level pediatric hospital. Patients: The cohort of 43 infants included 12 patients treated with extracorporeal membrane oxygenation. Evaluation was at 6 and 12 months; 33 infants were evaluated at both time points. Interventions: None. Measurements and Main Results: Maximal expiratory flow at functional residual capacity and functional residual capacity were measured with Masterscreen Babybody. Z-scores were calculated for maximal expiratory flow at functional residual capacity. Mean maximal expiratory flow at functional residual capacity values at 6 and 12 months were significantly below the expected values (mean z-score -1.4 and -1.5, respectively) without a significant change between both time points. Values did not signifi Conclusions: Infants with congenital diaphragmatic hernia have decreased expiratory flows and increased functional residual capacity within the first year of life. Extracorporeal membrane oxygenation-treated patients with congenital diaphragmatic hernia may have more respiratory morbidity and concomitant growth impairment. Close follow-up beyond the neonatal period is therefore required. (Pediatr Crit Care Med 2012; 13:e133-e139)
