BACKGROUND: The primary aim of this randomized study was to describe the feasibility of early administration of surfactant via a thin catheter during spontaneous breathing (Take Care) and compare early mechanical ventilation (MV) requirement with the InSurE (Intubate, Surfactant, Extubate) procedure. METHODS: Preterm infants, who were <32 weeks and stabilized with nasal continuous positive airway pressure (nCPAP) in the delivery room, were randomized to receive early surfactant treatment either by the Take Care or InSurE technique. Tracheal instillation of 100 mg/kg poractant α via 5-F catheter during spontaneous breathing under nCPAP was performed in the intervention group. In the InSurE procedure, infants were intubated, received positive pressure ventilation for 30 seconds after surfactant instillation, and placed on nCPAP immediately. RESULTS: One hundred infants in each group were analyzed. The MV requirement in the first 72 hours of life was significantly lower in the Take Care group when compared with the InSurE group (30% vs 45%, P = .02, odds ratio –0.52, 95% confidence interval –0.94 to –0.29). Mean duration of both nCPAP and MV were significantly shorter in the Take Care group (P values .006 and .002, respectively). Bronchopulmonary dysplasia rate was significantly lower among the infants treated with the Take Care technique (relative risk –0.27, 95% confidence interval –0.1 to –0.72) CONCLUSIONS: The Take Care technique is feasible for the treatment of respiratory distress syndrome in infants with very low birth weight. It significantly reduces both the need and duration of MV, and thus the bronchopulmonary dysplasia rate in preterm infants.
The effects of maternal influenza on the fetus are not well understood. Viremia is believed to occur infrequently and thus vertical transmission appears to be rare. Highly pathogenic strains of influenza virus, such as avian influenza A (H5N1), are more likely to be transmitted across the placenta. Placental tissues of seven women with confirmed H1N1 infection were examined molecularly with RT-PCR and microscopically to investigate whether H1N1 virus vertically transmitted. We found no evidence for placental transmission of H1N1 virus in this study. In the absence of vertical transmission, adverse effects like neonatal seizures, encephalopathy, cerebral palsy, and even neonatal death can still occur. Since a significant knowledge gap exists for the effects of this novel virus on the fetus, further studies will be beneficial.

Background: Fortification of human milk (HM) is a common clinical practice to adapt breast milk to the nutritional needs of very low birth weight (VLBW) infants. The optimal method for HM fortification remains to be determined, and a variety of protocols are currently used in neonatal intensive care units. Objective: It is believed that standard fortification is insufficient to meet the needs of VLBW infants. Therefore, we designed a randomized prospective study that investigated the effects of varying levels of blind fortification on short-term growth and metabolic responses of preterm infants. Methods: Eligible infants were randomized into 3 groups: standard fortification (SF), moderate fortification (MF), and aggressive fortification (AF). Short-term growth, feeding intolerance, and urea, calcium, phosphorus, and alkaline phosphatase levels were assessed. Results: There were 26, 29, and 29 infants in the SF, MF, and AF groups, respectively. The baseline characteristics of the groups were similar. Daily weight gain and length at discharge did not differ among the groups; however, head circumference was significantly higher in the MF and AF groups compared with the SF group. Urea, calcium, phosphorus, and alkaline phosphatase levels were similar between the groups. Conclusion: We demonstrated that blind fortification of HM, even with higher amounts than recommended by manufacturers, did not cause any measured adverse effects on the metabolic response of preterm infants. Anthropometric measurements (except head circumference) were not different between the different dosages of fortification.
