Abstract
Although fresh frozen plasma (FFP) transfusions are common practice in neonatology, robust evidence on their use is lacking. The aim of this study was to systematically review the literature for data on the practice of FFP transfusions in neonates and their association with neonatal morbidity and mortality. The authors identified 40 studies, which met the inclusion criteria for this review. It was demonstrated that the practice of FFP transfusions significantly varies throughout the world. The majority of FFP transfusions are administered "prophylactically", without evidence of active bleeding. Although FFP transfusions may restore coagulation tests results, they do not alter the clinical outcome of the neonates. Reactions following transfusions are probably underestimated in neonates, often undiagnosed and thus, underreported. High quality RCTs aiming to evaluate the effectiveness of FFP in specific clinical conditions are urgently needed, as they could change long-standing FFP transfusion practices, and help reduce neonatal morbidity and mortality.

Abstract
BACKGROUND Factor consumption is common during ECMO complicating the balance of pro and anticoagulation factors. This study sought to determine whether transfusion of coagulation factors using fresh frozen plasma (FFP) increased ECMO circuit life and decreased blood product transfusion. Secondly, it analyzed the association between FFP transfusion and hemorrhagic and thrombotic complications. STUDY DESIGN AND METHODS Thirty-one pediatric ECMO patients between October 2013 and January 2016 at a quaternary care institution were included. Patients were randomized to FFP every 48 hours or usual care. The primary outcome was ECMO circuit change. Secondary outcomes included blood product transfusion, survival to decannulation, hemorrhagic and thrombotic complications, and ECMO costs. RESULTS Median (interquartile range [IQR]) number of circuit changes was 0 (0, 1). No difference was seen in percent days without a circuit change between intervention and control group, P = .53. Intervention group patients received median platelets of 15.5 mL/kg/d IQR (3.7, 26.8) vs 24.8 mL/kg/d (12.2, 30.8) for the control group (P = .16), and median packed red blood cells (pRBC) of 7.7 mL/kg/d (3.3, 16.3) vs 5.9 mL/kg/d (3.4, 18.7) for the control group, P = .60. FFP transfusions were similar with 10.2 mL/kg/d (5.0, 13.9) in the intervention group vs 8.8 (2.5, 17.7) for the control group, P = .98. CONCLUSION In this pilot randomized study, scheduled FFP did not increase circuit life. There was no difference in blood product transfusion of platelets, pRBCs, and FFP between groups. Further studies are needed to examine the association of scheduled FFP with blood product transfusion.

Abstract
Blood transfusions following major burn injury are common due to operative losses, blood sampling, and burn physiology. While massive transfusion improves outcomes in adult trauma patients, literature examining its effect in critically ill children is limited. The study purpose was to prospectively compare outcomes of major pediatric burns receiving a 1:1 vs 4:1 packed red blood cell (PRBC) to fresh frozen plasma (FFP) transfusion strategy during massive burn excision. Children with >20% total body surface area (TBSA) burns were randomized to a 1:1 or 4:1 PRBC/FFP transfusion ratio during burn excision. Parameters examined include patient demographics, burn size, Pediatric Risk of Mortality (PRISM) scores, Pediatric Logistic Organ Dysfunction (PELOD) scores, laboratory values, total blood products transfused, and the presence of blood stream infections or pneumonia. A total of 68 children who met inclusion criteria were randomized into two groups (n=34). Mean age, PRISM scores, estimated blood loss (600 mL (400 - 1175 mL) v 600 mL (300 - 1150 mL), p = 0.68), ventilator days (5 v 9, p = 0.47), and length of stay (57 v 60 days, p = 0.24) had no difference. No differences in frequency of blood stream infection (20 v 18, p = 0.46) or pneumonia events (68 v 116, p = 0.08) were noted. On multivariate analysis, only TBSA burn size, inhalation injury, and PRISM scores (p < 0.05) were significantly associated with infections.

Abstract
We assessed the effect of fresh frozen plasma (FFP) on extracellular volume (ECV) during the first few days of life in two groups of preterm infants, group 1 (gestational age less than 30 weeks) and group 2 (gestational age 30-34 weeks). The infants were randomly assigned to one of two treatment groups, one receiving FFP, the other not; group 1 infants receiving no treatment (n = 8) and group 1 infants receiving FFP (n = 11), and group 2 infants receiving no treatment (n = 9) and group 2 receiving FFP (n = 10). FFP was given at a dose of 10 ml/kg daily during a two-hour period for the first three days of life. ECV was measured on day 1 before FFP was given and on day 4 by the distribution of bromide. There was a significant correlation between birth weight and initial ECV (r = 0.85, P less than 0.001). In group 1 ECV was significantly higher than in group 2 (P less than 0.02). In group 1 receiving no treatment mean weight loss and mean decrease in ECV were equal (84 g/kg and 78 ml/kg, respectively), but no correlation between the two parameters could be found (r = 0.68, P = 0.06). In the other study groups, mean weight loss was higher than mean decrease in ECV, with no correlation between weight loss and change in ECV.(ABSTRACT TRUNCATED AT 250 WORDS)
