The transfusion in pediatrics may require specific preparations to adapt to the various characteristics from preterm neonates to big child: weight, immaturity, immune system, blood volume, long and short-term prognosis, and to meet the needs of pathologies related to the perinatal period. The knowledge of the process for preparation, conservation and administration of these particular products shall permit a transfusion in safe conditions by supporting the prescribers in a personalized blood management.

Atrial fibrillation (AF) is a really uncommon arrhythmia in newborns. Here, we report the case of a 1-day-old infant who was recovered in Neonatal Intensive Care Unit for a twin-to-twin transfusion. The appearance of an unexpected AF was registered at his continuous electrocardiographic monitoring. Both chest X-ray and echocardiographic examination revealed the anomalous insertion of the tip of a central venous catheter (CVC) into the heart ('umbilical artery → inferior vena cava → right atrium → patent foramen ovale → left atrium')...

AIM: In this study, we evaluate the associations between fetal urinary production rate (FUPR), measured by ultrasound, and adverse neonatal outcome in women with preterm premature rupture of membranes (PPROM). METHODS: We conducted a prospective pilot cohort of singleton pregnancies complicated by PPROM occurring at gestational week 24 or later managed until spontaneous labor (after 48 h of admission), chorioamnionitis, or induction by protocol at 35 + 0 weeks. FUPR was evaluated by 2D sonography at admission (corrected for gestational age)...

BACKGROUND: The efficacy of antenatal corticosteroid treatment for women with threatened preterm birth depends on timely administration within 7 days before delivery. We modelled the probability of delivery within 7 days of admission to hospital among women presenting with threatened preterm birth, using routinely collected clinical characteristics. METHODS: Data from the Canadian Perinatal Network (CPN) were used, 2005-11, including women admitted to hospital with preterm labour, preterm pre-labour rupture of membranes, short cervix without contractions, or dilated cervix or prolapsed membranes without contractions at preterm gestation...

BACKGROUND: To evaluate the clinical significance of primary symptoms in women with placental abruption. METHODS: A retrospective study of 273 cases of placental abruption was performed. The subjects were classified into 2 groups according to primary symptoms: 210 cases of vaginal bleeding group and 63 cases of abdominal pain group. The clinical features, maternal and neonatal outcomes were compared between two groups. RESULTS: The incidence of preeclampsia and preterm birth in vaginal bleeding group was significantly lower than abdominal pain group, while the incidence of premature rupture of membrane (PROM) in the former group was higher than that in the latter group...

Sclerema neonatorum is a form of panniculitides characterized by diffuse hardening of subcutaneous tissue with minimal inflammation. It usually affects ill and preterm neonates. Prognosis is usually poor in many cases despite aggressive management. Various treatment modalities (antibiotics, intravenous immunoglobulin, steroids, and exchange transfusion) have been explained in literature. Steroids due to its easy availability and low cost can prove to be lifesaving in such cases, especially in resource poor countries...

Twenty-eight-week-old preterm monochorionic-diamniotic twins were admitted to the neonatal intensive care unit secondary to low birth weight and mild respiratory distress syndrome. A low fibrinogen level of less than 0.5 g/L was detected following an abnormal full blood count. They required fibrinogen transfusions until 32 weeks corrected gestation to maintain adequate fibrinogen levels. Parental screening revealed that their mother had a previously undiagnosed hypofibrinogenaemia. Of note, her only symptom was menorrhagia...

BACKGROUND: The Eunice Kennedy Shriver National Institute of Child Health and Human Development Stillbirth Collaborative Research Network previously demonstrated an association between stillbirth and maternal marijuana use as defined by the presence of 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid in the umbilical cord homogenate. However, the relationship between marijuana use and perinatal complications in live births is uncertain. OBJECTIVE: Our aim was to examine if maternal marijuana use is associated with increased odds of adverse pregnancy outcomes and neonatal morbidity among live-born controls in the Stillbirth Collaborative Research Network cohort...

Professional societies have published recommendations for iron dosing of preterm neonates, but differences exist between guidelines. To help develop standardized guidelines, we performed a 10-year analysis of iron dosing in groups at risk for iron deficiency: IDM (infants of diabetic mothers), SGA (small for gestational age), and VLBW premature neonates (very low birth weight, <1500 g). We analyzed iron dosing after red cell transfusions and erythropoiesis-stimulating agents (ESA). Of IDM, 11.8% received iron in the hospital; 9...

BACKGROUND: The introduction of the Solomon technique for the treatment of twin-twin transfusion syndrome (TTTS) increased placental exposure to laser energy. This study aims to identify the impact of power and energy used in laser treatment on placental tissue and pregnancy outcome. METHODS: Pictures of all dye-injected placentas since the start of the Solomon trial were analyzed. Placental damage was scored using a grading system including visual scar depth and affected proportion of the vascular equator...

OBJECTIVE: The association between infection and inflammatory response in singleton preterm birth (PTB) is well established, yet, less is known about PTB in twins. We aimed to compare the placental component and pregnancy outcome in pregnancies complicated with PTB of singletons vs. twin deliveries. We hypothesized that due to different underlying mechanisms, placental inflammatory lesions will be more prevalent in placentas derived from singleton pregnancies than twins. STUDY DESIGN: Labor characteristics, neonatal outcome and placental histopathology reports of spontaneous PTB at 24-33(6)/7 weeks, from 1/2008-12/2015, were reviewed...

BACKGROUND: Excess of iron and oxidant injury shortly after birth may be associated with neonatal morbidities in preterm infants. AIMS: The aim was to determine whether administration of erythropoietin without iron supplementation decreases iron load and morbidity. STUDY DESIGN AND SUBJECTS: In a randomized trial, we administered erythropoietin (EPO 250IU/kg daily during the first 6days of life) or placebo to 39 preterm infants (BW 700-1500g, GA≤30...

INTRODUCTION: The blood count provides qualitative and quantitative essential information on bloodlines. Reference hematologic parameters have been established in children and neonates, but few data are available regarding the premature population during the first month of life. The main objective of this study was to establish normative values for blood parameters for premature infants born between 26 and <37 weeks of gestation, during the first month of life, taking into account gestational and postnatal age and treatments that can impact the threshold values...

The optimal threshold for neonatal platelet transfusions in sick newborns is still uncertain. We report a congenital cytomegalovirus (CMV) infection in a premature neonate with severe thrombocytopenia who subsequently presented with necrotizing enterocolitis and intestinal bleeding. The baby recovered after platelet transfusions were discontinued and the therapy was switched from intravenous ganciclovir to oral valganciclovir. We discuss both measures, speculating on the key role of platelet transfusions.
