PRBC TRANSFUSIONS IN TERM NEONATES

Objective To determine if treatment with IVIG of neonates with ABO incompatibility (without Rh incompatibility) results in decreased number of packed red blood cell (pRBC) transfusions and phototherapy use. Study Design An IRB-approved, single-institution retrospective study was conducted. Neonates ≥38 weeks gestational age born between 01/01/2007 and 12/31/2016 with ABO incompatibility were included. The comparison among groups was performed using Chi square and Fisher exact test for categorical variables; continuous variables were assessed by Kruskal-Wallis test...

OBJECTIVES: To assess the feasibility of drawing, processing, safety-testing, and banking term umbilical cord blood to meet the packed red blood cell transfusion (RBC Tx) needs of extremely-low-gestational-age neonates (ELGANs). DESIGN: (1) Retrospectively analyze all ELGANs RBC Tx over the past three years, (2) Estimate local cord blood availability, (3) Assess interest in this project, and implementation barriers, through stakeholder surveys. RESULTS: In three years we cared for 266 ELGANs; 165 (62%) received ≥1 RBC Tx...

BACKGROUND: The incidence of early-onset vitamin K deficiency bleeding (VKDB) in at-risk neonates who did not receive vitamin K supplementation varied from 6 to 12%. This case report aims to show that VKDB can occur abruptly after birth despite vitamin K1 1 mg IM being given immediately after birth. CASE PRESENTATION: A term female baby was born through vaginal delivery of a 28 years old mother, G1P0A0, 39-40 weeks gestation with normal APGAR score, and birth weight was 3445 g, birth length was 52 cm...

Volume expanders are indicated in the delivery room when an asphyxiated neonate is not responding to the steps of neonatal resuscitation and has signs of shock or a history of acute blood loss. Fetal blood loss (e.g., feto-maternal hemorrhage) may contribute to perinatal asphyxia. Cord compression or a tight nuchal cord can selectively occlude a thin-walled umbilical vein, resulting in feto-placental transfusion and neonatal hypovolemia. For severe bradycardia or cardiac arrest secondary to fetal blood loss, Neonatal Resuscitation Program (NRP) recommends intravenous volume expanders (crystalloids such as normal saline or packed red blood cells) infused over 5 to 10 min...

A term Caucasian neonate with an uncomplicated birth history presented with persistent umbilical stump bleeding unresponsive to extensive topical haemostatic measures initially. He subsequently developed hypovolaemic shock. Routine full blood count and basic coagulation screen were unremarkable. He received packed red cell and cryoprecipitate transfusions. Further specialist coagulation studies performed revealed factor XIII deficiency. Genetic investigations demonstrated a compound heterozygosity for the disorder...

OBJECTIVES: To evaluate the maternal and neonatal outcomes of expected and unexpected pathologically proven placenta accreta spectrum (PAS) cases in a single multidisciplinary center. MATERIAL AND METHODS: This was a retrospective cohort study of 92 PAS cases from January 2011 until September 2021. Only cases with histopathologically invasive placentation were included in the study. The cases diagnosed at the time of delivery were defined as unexpected PAS (uPAS) and those diagnosed antenatally as expected PAS (ePAS)...

BACKGROUND: The few studies that have addressed the relationship between severity of intrapartum fever and neonatal and maternal morbidity have had mixed results. The impact of the duration between reaching maximum intrapartum temperature and delivery on neonatal outcomes remains unknown. OBJECTIVE: To test the association of severity of intrapartum fever and duration from reaching maximum temperature to delivery with neonatal and maternal morbidity. STUDY DESIGN: This was a secondary analysis of a prospective cohort of term, singleton patients admitted for induction of labor or spontaneous labor who had intrapartum fever (≥38°C)...

OBJECTIVE:  Extremely low birth weight (ELBW) infants often receive transfusions of packed red blood cells (PRBCs). Long-term outcomes of infants treated with liberal versus restricted transfusion criteria have been evaluated with conflicting results. Clinicians incorporate a reticulocyte count (RC) in their transfusion decisions. There is a lack of information on reference ranges for RCs in growing ELBW infants and whether infant's chronologic age or corrected gestational age (GA) generates a specific trend in the RCs...

BACKGROUND/PURPOSE: To evaluate whether a shorter length (20 cm) of C-UCM has potential benefits, compared to immediate cord clamping (ICC), in very preterm babies. METHODS: Inborn preterm infants less than 30 weeks of gestational age (GA) were randomly assigned to the 20-cm C-UMC and ICC groups. The primary outcome was the need for packed red blood cell (pRBC) transfusion before the 21st day of life. The secondary outcomes were short- and long-term outcomes related to premature birth...

BACKGROUND: Red blood cell (RBC) transfusions have been implicated in the development of necrotizing enterocolitis (NEC) in premature infants. Some evidence exists to support that withholding feedings during transfusion reduces the risk of subsequent NEC development. PURPOSE: To review the most recent literature on this topic to determine best evidence-based practice regarding withholding or not withholding feedings during RBC transfusions. METHODS/SEARCH STRATEGY: Four databases were searched using keywords and MeSH terms including "necrotizing enterocolitis," "NEC," "NPO," and "transfusion," with specifications limiting the search to articles published in the last 10 years and limiting the population to neonates...

Conventionally the packed red blood cell (PRBC) transfusion volume given to neonates is 10 ml/kg to 20 ml/kg. The weight-based formulae underestimate the volume of PRBC required to achieve a target hematocrit (Hct) in preterm neonates. The study was done to compare the rise in Hct after transfusing PRBC volume calculated either based on body weight or using formula considering Hct of blood bag and Hct of preterm neonates. This prospective study included a total of 68 preterm neonates requiring transfusion for the first time having ≤ 34 weeks of gestational age...

Background: Anemia remains a common comorbidity of preterm infants in the neonatal intensive care unit (NICU). Left untreated, severe anemia may adversely affect organ function due to inadequate oxygen supply to meet oxygen requirements, resulting in hypoxic tissue injury, including cerebral tissue. To prevent hypoxic tissue injury, anemia is generally treated with packed red blood cell (RBC) transfusions. Previously published data raise concerns about the impact of anemia on cerebral oxygen delivery and, therefore, on neurodevelopmental outcome (NDO)...

OBJECTIVE: To compare the characteristics and short-term outcomes in extremely preterm infants, who developed necrotizing enterocolitis (NEC) following a packed red blood cell transfusion (pRBC) within 48 h (TANEC), with those who developed NEC beyond 48 h (non-TANEC). SETTING: A single-center retrospective cohort study in a Tertiary neonatal intensive care unit in the UK over a 5-year period. PATIENTS AND METHODS: Extremely premature infants (23-27 weeks gestation) were selected...

OBJECTIVE: Thromboelastography (TEG) is a point-of-care device used to evaluate whole blood coagulation function. The TEG is unique as a test of coagulation function in that it measures the interaction of all components of clot formation, which is different than traditional laboratory-based tests which measure isolated components of coagulation. Little is known about fetal coagulation physiology. We sought to evaluate the impact of severe fetal anemia and intrauterine transfusion (IUT) on fetal coagulation physiology by use of the TEG, and to compare fetal TEG values to those of healthy neonates and adults...

BACKGROUND OF THE STUDY: In neonates with Rh-hemolytic disease, light emitting diode (LED) phototherapy allows delivery of high spectral irradiance (SI). A linear correlation exists between SI and efficacy of phototherapy with no saturation point. There is scant data on evaluation and early phototherapy using LED units in Rh-hemolytic disease. OBJECTIVE: This study aimed to describe the hemoglobin (Hb), hematocrit (Hct), total serum bilirubin (TSB), phototherapy parameters and short-term outcomes in neonates with Rh-hemolytic disease...

Oxidative stress is a frequent condition in critically ill patients, especially if exposed to extracorporeal circulation, and it is associated with worse outcomes and increased mortality. The inflammation triggered by the contact of blood with a non-endogenous surface, the use of high volumes of packed red blood cells and platelets transfusion, the risk of hyperoxia and the impairment of antioxidation systems contribute to the increase of reactive oxygen species and the imbalance of the redox system. This is responsible for the increased production of superoxide anion, hydrogen peroxide, hydroxyl radicals, and peroxynitrite resulting in increased lipid peroxidation, protein oxidation, and DNA damage...

OBJECTIVE: We are reporting a case of acquired B phenomenon in a 14 days old pre-term baby presenting with necrotizing enterocolitis (NEC) where it was detected as an ABO discrepancy. METHOD: The forward and reverse grouping was done using tube technique as well as column agglutination technique (ABD card and LISS Coombs AHG gel cards, Biorad, Switzerland). The direct antiglobulin test (DAT) was also done on gel card. Further work up was done using acidified (0...

OBJECTIVE: To evaluate the short-term effects of feed fortification, feed volume increase, and PRBC transfusion on the odds of developing NEC. STUDY DESIGN: Case-crossover study of neonatal intensive care infants born at ≤ 32 weeks' gestation who were admitted to 5 central Ohio intensive care units from January 2012-July 2016 and developed NEC Bell Stage ≥2. Each patient served as their own control, with exposure during the 48-hour period just prior to NEC onset (hazard period) being compared to a preceding 48-hour control period, thus eliminating confounding by patient factors fixed between both intervals...

OBJECTIVE: To determine whether packed red blood cell (PRBC) transfusion affects post-prandial superior mesenteric artery blood flow velocities (SMA BFVs) in very-low birth weight (VLBW) neonates and if so, at what time point after transfusion restoration of previous SMA BFV patterns occurs. DESIGN/METHODS: VLBW pre-term neonates, older than 14 days and tolerating bolus enteral feedings administered every 3 h were enrolled in this prospective observational study...
