RESUMEN
BACKGROUND: Several reports have shown the beneficial effects of early or prophylactic surfactant therapy for preterm infants, who often develop respiratory distress syndrome. No report, however, has addressed which infants should receive surfactant therapy in the delivery room. Therefore, the aim of this study was to assess the validity of identifying infants who need surfactant therapy based on fraction of inspiratory oxygen (FiO2 ) requirement in the delivery room. METHODS: In this observational, retrospective study, FiO2 given in the delivery room, use of surfactant therapy, stable microbubble test (SMT) results, and changes in FiO2 both before and after surfactant therapy were reviewed in infants born at <33 weeks' gestation. RESULTS: Overall, 170 infants were included. Forty infants were given oxygen with FiO2 ≥0.6, and all received surfactant therapy. Of these 40 infants, FiO2 could be reduced in 36 (90%) by an average of 0.46 after surfactant therapy. SMT was done in 22 of 40 infants, and surfactant insufficiency was suspected in 20 (91%). In contrast, 81 of 102 infants (79%) with FiO2 <0.4 did not need surfactant therapy within 48 h after birth. CONCLUSIONS: Preterm infants who need FiO2 ≥0.6 in the delivery room appear to be at high risk of surfactant insufficiency and would benefit from surfactant. Surfactant therapy would provide a more effective resuscitation method for preterm infants, and thus a larger prospective study is needed to confirm these results.

Acute encephalopathy with biphasic seizures and reduced diffusion (AESD) encompasses a group of encephalopathy characterized by biphasic seizures and disturbance of consciousness in the acute stage followed in the subacute stage by reduced diffusion in the subcortical white matter on magnetic resonance imaging. The etiology of AESD is viral infection and associated pathological changes. Here we report the first case of AESD caused by bacterial infection (Streptococcus pneumoniae meningitis) in a 1-year-old boy.
