RESUMEN
OBJECTIVE: To determine whether the application of occlusive wrap applied immediately after birth will reduce mortality in very preterm infants. STUDY DESIGN: This was a prospective randomized controlled trial of infants born 24 0/7 to 27 6/7 weeks' gestation who were assigned randomly to occlusive wrap or no wrap. The primary outcome was all cause mortality at discharge or 6 months' corrected age. Secondary outcomes included temperature, Apgar scores, pH, base deficit, blood pressure and glucose, respiratory distress syndrome, bronchopulmonary dysplasia, seizures, patent ductus arteriosus, necrotizing enterocolitis, gastrointestinal perforation, intraventricular hemorrhage, cystic periventricular leukomalacia, pulmonary hemorrhage, retinopathy of prematurity, sepsis, hearing screen, and pneumothorax. RESULTS: Eight hundred one infants were enrolled. There was no difference in baseline population characteristics. There were no significant differences in mortality (OR 1.0, 95% CI 0.7-1.5). Wrap infants had statistically significant greater baseline temperatures (36.3°C wrap vs 35.7°C no wrap, P < .0001) and poststabilization temperatures (36.6°C vs 36.2°C, P < .001) than nonwrap infants. For the secondary outcomes, there was a significant decrease in pulmonary hemorrhage (OR 0.6, 95% CI 0.3-0.9) in the wrap group and a significant lower mean one minute Apgar score (P = .007) in the wrap group. The study was stopped early because continued enrollment would not result in the attainment of a significant difference in the primary outcome. CONCLUSION: Application of occlusive wrap to very preterm infants immediately after birth results in greater mean body temperature but does not reduce mortality.

OBJECTIVE: To report the outcomes of an institutional protocol for periprocedural anticoagulant (AC) management in children with acute lymphoblastic leukemia (ALL). STUDY DESIGN: Children being treated for ALL who received full-dose (therapeutic) anticoagulation before undergoing at least 1 lumbar puncture (LP) were included in this retrospective cohort study. The main outcome was the risk of traumatic LP; exploratory analysis included the risks of symptomatic spinal hematoma and progression/recurrence of the thrombotic event. Analyses were conducted using logistic regression analysis with a generalized estimating equation approach. RESULTS: Twenty-two children with ALL receiving an AC underwent a total of 396 LPs. Although traumatic LP was associated with full-dose AC therapy in univariable analysis, a multiple logistic regression model controlling for other risk factors for traumatic LP showed that AC therapy was not significantly associated with the risk of traumatic LP when the ACs were held as per the institutional protocol. No patient developed symptomatic spinal hematoma. Exploratory analysis revealed that AC dose, a likely marker of thrombus burden, was significantly associated with progression/recurrence of the thrombotic event in univariable analysis. CONCLUSION: In our cohort, recent AC therapy was not statistically associated with an increased risk of bleeding after LP when following a specific protocol for periprocedural AC management. The risk associated with the progression/recurrence of thromboembolic events requires further evaluation.
