OBJECTIVE: To monitor altered mesenteric tissue oxygen saturation (StO2) before and after blood transfusion. METHODS: We placed a 4-wavelength NIRS sensor (FORE-SIGHT, CASMED, Branford, CT USA) on the right lower abdominal quadrant prior to transfusion and measured StO2 for up to 48 hours post transfusion. Pulse oximetry (SpO2) data was collected simultaneously, with fractional tissue oxygen extraction (FTOE) and the [SpO2-StO2] difference calculated to normalize for hypoxic episodes...

OBJECTIVE: Randomized controlled trials have demonstrated that delayed umbilical cord clamping (DCC) in preterm infants results in improved neonatal outcomes, including increased hematocrit, and decreased rates of intraventricular hemorrhage (IVH) and packed red blood cell transfusions. We hypothesized that implementation of a DCC policy in preterm infants would result in similarly improved outcomes, despite initial clinician resistance. STUDY DESIGN: A DCC policy (30-60 s) for singleton infants <35 weeks gestation was implemented in September 2011...

BACKGROUND: Preterm infants may inadvertently be exposed to lead from the packed red blood cell (pRBC) transfusions with almost no or very limited data available. The aim of the study was to quantify this exposure in preterm infants ≤30 wk gestational age (GA). METHODS: Prospective cohort study, infants ≤30 wk GA were eligible, infants < 23 wk GA and known chromosomal diseases were excluded. Blood lead levels (BLLs) were obtained at birth, before and after each transfusion, and at discharge...

OBJECTIVE: To investigate the association of PRBC transfusion and the development of NEC in VLBW preterm infants at a tertiary care neonatal unit. METHODS: A retrospective case-control study was performed. All VLBW infants (gestational age ≤32 week and birth weight <1500 g) born between 1999 and 2013 were included. Cases and controls were divided into four groups: (1) Infants who received PRBC transfusion and developed NEC within 48 hours of transfusion; (2) Infants who received PRBC transfusion and did not develop NEC; (3) Infant who developed NEC and did not receive PRBC transfusion; and (4) Infants who neither developed NEC nor received PRBC transfusion...

OBJECTIVE: The purpose of this study was to test the hypothesis that a standardized multidisciplinary treatment approach in patients with morbidly adherent placenta, which includes accreta, increta, and percreta, is associated with less maternal morbidity than when such an approach is not used (nonmultidisciplinary approach). STUDY DESIGN: A retrospective cohort study was conducted with patients from 3 tertiary care hospitals from July 2000 to September 2013. Patients with histologically confirmed placenta accreta, increta, and percreta were included in this study...

OBJECTIVE: The aim of this study was to evaluate the effects of umbilical cord milking (UCM) on the need for packed red blood cell (PRBC) transfusion and hematologic and hemodynamic parameters in very-low-birth-weight infants. METHODS: The infants were randomized into 2 groups: group 1 (UCM) and group 2 (control). The primary outcome was the number of PRBC transfusions during the first 35 days of life. The secondary outcome measures were the hemodynamic variables during the first 24 hours of life...

Anemia and the need for transfusion of packed red blood cells (PRBCs) are common in preterm infants. PRBC transfusion increases the oxygen carrying capacity of hemoglobin and may result in higher rates of organ dysfunction. To determine whether PRBC transfusion in preterm infants is associated with an increased incidence of bronchopulmonary dysplasia (BPD), this retrospective study was performed on neonates with birth weights ≤ 1,500 g or gestational age ≤ 32 weeks admitted from August, 2008 to November, 2013...

BACKGROUND: Preterm infants have a greater risk of necrotizing enterocolitis following transfusion. It is hypothesized that high glucose concentrations in red blood cell (RBC) preservatives lead to increased methylglyoxal (MG) metabolism, causing glycation-driven damage to transfused RBCs. Such changes to the RBCs could promote a proinflammatory state in transfusion recipients. METHODS: Standard and washed RBCs in Adsol-3, two common neonatal preparations, were studied...

BACKGROUND: Cases of necrotizing enterocolitis occurring within 48 h of packed red blood cell (PRBC) transfusions are increasingly being described in observational studies. Transfusion-associated gut injury is speculated to result from an abnormal mesenteric vascular response to transfusion. However, the mechanism of disruption of the balance between mesenteric vasoconstriction and relaxation following transfusion is not known. METHODS: Preterm lambs (n = 16, 134 d gestation; term: 145-147 d) were delivered and ventilated for 24 h...

REVIEW
Alexandra Luton
Necrotizing enterocolitis (NEC) is a leading cause of prolonged hospitalizations for premature infants in the United States. In a recent large retrospective study, a significant proportion of NEC cases were shown to occur within 48 hours of packed red blood cell (PRBC) transfusion, especially in growing preterm neonates of older postnatal age. A small body of evidence consistently demonstrates that 25-35 percent of NEC cases are temporally associated with PRBC transfusion and that cases of NEC associated with transfusion are generally more severe with a higher rate of surgical intervention and mortality...

BACKGROUND: Transfusion of packed red blood cells (PRBCs) saves lives in the neonatal critical care setting and is one of the most common interventions in the preterm infant. The number and volume of PRBC transfusions are associated with several major neonatal morbidities, although a direct causal link between transfusion and major neonatal morbidity is still to be proven. Transfusion-related immunomodulation (TRIM) may underlie these adverse outcomes, yet it has received little attention in the high-risk preterm infant...

AIM: Both patent ductus arteriosus (PDA) and packed red blood cell (PRBC) transfusion are risk factors for necrotizing enterocolitis (NEC). The combination of PDA and PRBC transfusion may have a synergistic effect on the intestinal circulation. METHODS: We present four cases of NEC in very low birth weight (VLBW) infants within 14 h after PRBC transfusion. RESULTS: All infants were growing on full enteral feeding, and they all had a PDA. CONCLUSION: We are concerned that the simultaneous presence of a PDA and PRBC transfusion in VLBW infants may place the infant at even greater risk of NEC than each of these factors alone...

Transfusion-transmitted malaria (TTM) in neonates is rare. TTM can occur in both endemic and nonendemic areas because the current tests used to screen the donor blood for malaria are unreliable when there is low parasitemia. Malaria must be considered as an important differential diagnosis for neonatal sepsis after exchange transfusion. Management strategy in TTM in the neonatal period is not standardized; exchange transfusion is often considered. We used intravenous artesunate in a case of severe malaria caused by Plasmodium vivax in a 30-week preterm neonate after packed red blood cell transfusion on day 19 of life...

BACKGROUND: Although many therapeutic interventions are necessary for the survival of the preterm infant, understanding the potential effects of these treatments is important to decrease the rate of necrotizing enterocolitis (NEC) in preterm infants. OBJECTIVE: The aim of this study was to examine the relationship between preterm infant treatments administered prior to the development of NEC, specifically the number of packed red blood cell (PRBC) transfusions, weeks of antibiotic therapy for nosocomial infection, and number of mechanical ventilation days, and the development of NEC in preterm infants...

This prospective observational study conducted in a neonatal intensive care unit aimed to evaluate echocardiographic changes provoked by anemia and transfusion of packed red blood cells (pRBCs) in premature infants. In this study, 32 anemic premature infants had serial echocardiographic assessment of left ventricular (LV) systolic performance, LV preload, and afterload immediately before, within 48 h, and up to 120 h after the transfusion of pRBCs. Pretransfusional evaluations also were compared with similar assessments of 71 nonanemic inpatient premature infants analogous for sex, gestational age at birth, and postnatal age...

OBJECTIVE: To determine association of anemia and red blood cell (RBC) transfusions with necrotizing enterocolitis (NEC) in preterm infants. STUDY DESIGN: A total of 111 preterm infants with NEC ≥ stage 2a were compared with 222 matched controls. In all, 28 clinical variables, including hematocrit (Hct) and RBC transfusions were recorded. Propensity scores and multivariate logistic regression models were created to examine effects on the risk of NEC. RESULT: Controlling for other factors, lower Hct was associated with increased odds of NEC (odds ratio (OR)=1...

OBJECTIVE: The safe lower limit of haematocrit or haemoglobin that should trigger a red blood cell (RBC) transfusion has not been defined. The objective of this study was to examine the physiological effects of anaemia and compare the acute responses to transfusion in preterm infants who were transfused at higher or lower haematocrit thresholds. METHODS: The authors studied 41 preterm infants with birth weights 500-1300 g, who were enrolled in a clinical trial comparing high ('liberal') and low ('restrictive') haematocrit thresholds for transfusion...
