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.

Archives of Disease in Childhood. 1985;60((8):):710-3.
Abstract
Seventy three preterm infants weighing less than 1500 g or less than 32 weeks' gestation, or both, were allocated randomly to treatment (fresh frozen plasma 10 ml/kg on admission and at 24 hours of age) or control groups. Fifteen (41%) out of 37 control patients sustained intraventricular haemorrhage compared with five (14%) of 36 patients receiving treatment (X2 = 5.24, P = 0.022). No difference was found in coagulation factors measured at birth or at 48 hours of age in both groups. Fresh frozen plasma appears to have a beneficial effect in the prevention of intraventricular haemorrhage.
