Brain death secondary to arteriovenous hemangioma of the forearm.

We describe the association of brain death in an infant with a large cutaneous hemangioma of the forearm. The irreversible cerebral injury is presumed to be secondary to cerebral hypoperfusion as a result of a combination of systemic hypotension and a systemic vascular "steal" phenomenon caused by the cutaneous hemangioma.

High-frequency oscillation and paralysis stabilize surfactant protein-B--deficient infants.

OBJECTIVE: To determine if high-frequency oscillatory ventilation and neuromuscular blockade improve oxygenation and chest radiographic appearance more effectively than high-frequency oscillation alone for surfactant protein-B (SP-B)--deficient infants. STUDY DESIGN: We reviewed medical records and chest radiographs of five SP-B--deficient infants awaiting lung transplantation. Changes in FiO2 and radiographic scores were analyzed with respect to neuromuscular blockade status. RESULTS: FiO2 consistently increased 0.20 (SD 0.11) during high-frequency ventilation without neuromuscular blockade (p = 0.02) and decreased 0.14 (SD 0.11) during high-frequency ventilation with neuromuscular blockade (p = 0.05). Chest radiographic appearance, quantified by an expansion/aeration index, consistently deteriorated without neuromuscular blockade (p = 0.01) and consistently improved with neuromuscular blockade (p = 0.03). Changes in FiO2 correlated with changes in radiograph scores (r = 0.7, p < 0.001). CONCLUSIONS: High-frequency ventilation with neuromuscular blockade optimizes oxygenation for SP-B--deficient infants. This ventilatory strategy should be considered while awaiting the diagnosis of SP-B deficiency or lung transplantation.
