RESUMO
OBJECTIVE: The relationship between bronchopulmonary dysplasia (BPD) and neurodevelopmental outcome after extracorporeal membrane oxygenation (ECMO) has not been extensively reported. We compared the outcomes in a large series of infants with and without BPD after ECMO. STUDY DESIGN: Hospital charts and follow-up records of 145 infants treated with ECMO (1985 through 1990) were reviewed. Complete long-term respiratory and follow-up outcome data were available in 64 infants. BPD occurred in 17 survivors; the remaining 47 did not have BPD. RESULTS: Babies with BPD were more likely to have had respiratory distress syndrome. Mean (+/- SD) age at ECMO initiation was later for the BPD group (127+/-66 vs 53+/-39 hours, p < 0.001), and the duration of ECMO treatment was longer (192+/-68 vs 119+/-53 hours, p < 0.001). Bayley Scales of Infant Development scores at <30 months were lower in infants with BPD (p < 0.001), as were three of four Mullen Scales of Early Learning scores (> or = 30 months, p < 0.001 or p = 0.01). At 57+/-16 months 11 (64%) patients with BPD had mild neurologic disabilities, and 3 (18%) had severe disabilities. At a similar age (53+/-16 months, p = NS) 16 (34%) patients without BPD had mild disabilities, whereas 2 (4%) had severe disabilities (p < 0.01). CONCLUSIONS: The occurrence of BPD after ECMO is associated with adverse neurodevelopmental outcome. Patients with BPD after ECMO merit close long-term follow-up.

OBJECTIVE: To determine risk factors for the development of bronchopulmonary dysplasia (BPD) after treatment with extracorporeal membrane oxygenation (ECMO). DESIGN: Retrospective case-control study. SETTING: Tertiary care level 3 neonatal intensive care unit. PARTICIPANTS: Seventy-three newborns treated with ECMO for severe respiratory failure during a 5-year period, who survived until day of life 28, and who did not have pulmonary hypoplasia as the initial cause for respiratory failure. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The presence of BPD after treatment with ECMO, which was defined as oxygen and/or ventilatory requirements at day of life 28, with characteristic abnormalities seen on chest x-ray film. RESULTS: The age at ECMO initiation was significantly greater for patients with BPD compared with patients without BPD (mean +/- SD, 135 +/- 68 hours vs 50 +/- 37 hours; P < .001). There was an 11.5-fold increased risk for the development of BPD if ECMO was initiated at greater than 96 hours of age. The primary diagnosis of respiratory distress syndrome imparted a 5.2-fold increased risk for the development of BPD. Patients with BPD required ECMO significantly longer than patients without BPD (203 +/- 73 hours vs 122 +/- 51 hours; P < .001). CONCLUSION: These results demonstrate that delayed use of ECMO in treating neonatal respiratory failure is associated with an increased risk for the development of BPD and a longer duration of ECMO therapy.

Neonates treated with extracorporeal membrane oxygenation (ECMO) for respiratory failure have a high frequency of complications related to systemic anticoagulation, ECMO and other life-support lines and catheters, and the antecedent pulmonary disease. Many of these complications involve the thorax and can be defined on chest radiographs or thoracic sonograms. The purpose of this essay is to illustrate the findings of the various thoracic complications of ECMO on chest radiographs and sonograms. This study is based on a review of the medical records and findings on chest radiographs and sonograms of 150 neonates who were treated with ECMO at our institution.
