The effect of blood transfusion to maintain a preset packed cell volume (PCV) level in preterm ventilated infants has been investigated. Fifty infants, median gestational age 26 (range 23-33) weeks and postnatal age 4 (1-29) days, transfused a median of 15 ml/kg of blood in response to a PCV < ...
Doyle J J - - 1997
Neonatal erythropoiesis is limited by a relatively inadequate production of erythropoietin. This is likely the result of dependence on the hepatic production of erythropoietin and an incomplete switchover to renal production. The present model of neonatal erythropoiesis suggests that the use of exogenous erythropoietin should correct the early anemia of ...
Hume H - - 1997
Increasingly clinicians attempt to base decisions regarding patient management on the results of clinical studies in addition to expert opinion and their own practical experience. In this article, the author reviews the published studies available to assist clinicians to make evidence-based decisions in three topics related to small volume red ...
Meister B - - 1997
In vitro and animal studies suggest that high concentrations of recombinant human erythropoietin (rHuEPO) might divert multipotent progenitors into erythroid maturation at the expense of granulocyte production. We determined whether changes of number and lineage commitment of peripheral blood progenitor cells occur in premature infants during therapy with rHuEPO. Thirty ...
Kling P J - - 1997
OBJECTIVE: To test the hypothesis that utilization of a previously described measure of acuity (ie, the score for neonatal acute physiology [SNAP]) during the first 7 postnatal days predicts which infants with a birth weight of 1500 g or less received erythrocyte transfusion during the initial hospitalization. DESIGN: Retrospective chart ...
Cooke R W - - 1997
Frequent blood transfusions may produce changes in iron status which can give rise to oxygen-derived free-radical (ODFR) generation and oxidative injury. Preterm infants developing chronic lung disease (CLD) receive significantly more transfusions. A total of 73 very preterm infants had weekly estimations of serum iron, transferrin, transferrin saturation, ferritin, caeruloplasmin, ...
Ancora G - - 1997
The present study reports immunohematological data (anti-erythrocyte titer, anti-erythrocyte functional activity, percentage of sensitized erythrocytes) in 11 patients with erythroblastosis fetalis transfused in utero (IUTd). At birth it was possible to define two groups of newborns: one with low (group 1) and one with high (group 2) percentage of circulating ...
Kutvirt S G - - 1996
The immunomodulating effects of repeated exposure to blood from multiple donors coupled with an immature immune system may predispose the preterm neonate to an increased incidence of infection in his first few months of life. To test this hypothesis, we compared lymphocyte phenotypes, serum IgG concentrations, and histories of infection ...
Widness J A - - 1996
OBJECTIVE: Anemia develops in increasing numbers of critically ill very low birth weight (VLBW) infants who survive the neonatal period, and they receive multiple red blood cell (RBC) transfusions. Despite their need for prolonged medical treatment, we hypothesized that VLBW infants presently receive fewer RBC transfusions as a result of ...
Kirsten G F GF Department of Paediatrics, Tygerberg Hospital, W. - - 1996
To conduct an audit of the frequency of red cell concentrate transfusions (RCCTs) in infants of different weight categories, the donor exposure rate (DER), in these transfused infants and the volume of blood wasted during each transfusion, and to identify from this baseline information specific categories of infants who would ...
Strauss R G - - 1996
BACKGROUND: Despite recent optimism about the use of erythropoietin therapy to treat the anemia of prematurity, very-low-birth-weight infants who are severely ill receive multiple red cell (RBC) transfusions. Many physicians transfuse relatively fresh RBCs to newborn infants, exposing them to multiple donors and possibly increasing their risk of acquiring transfusion-transmitted ...

Although pediatric neurosurgeons traditionally have been trained to perform a sagittal synostectomy for the treatment of sagittal synostosis, numerous articles advocating modifications of this procedure or more complex cranial vault reconstructions point our the inadequacies of strip craniectomy in providing optimal short- and long-term cosmesis. This review addresses the major ...
Wu T J - - 1996
A term, male neonate suddenly developed respiratory distress and severe cyanosis while undergoing exchange transfusion for hyperbilirubinaemia. Transfusion-related acute lung injury was diagnosed. Because of persistent hypoxaemia despite aggressive treatment, two doses of surfactant were administered, resulting in marked improvement. Conclusion: Transfusion-related acute lung injury may occur in neonates, and ...

While PBSC collection has become a safe procedure for adults, only a few reports exist about its efficacy, safety and feasibility in paediatric patients, especially extremely low-weight infants. We describe successful PBSC collection in three infants of less than 10 kg body weight (BW; range: 6.92-9.4 kg) suffering from stage ...
Pöschl J M - - 1996
Neonates are more susceptible than adults to many Gram-positive and Gram-negative bacterial infections. Whereas group B streptococcus causes life-threatening infections in neonates, group A beta-haemolytic streptococcus infections rarely occur in neonates. To test the hypothesis that group A streptococcus may have different effects on neonatal and adult red blood cells ...
Ovali F - - 1996
The management of (Rhesus) hemolytic disease of the fetus and newborn includes intrauterine transfusions to prevent the development of hydrops, treatment of the possible hyperbilirubinemia in the immediate postnatal period, and treatment of late anemia. Low levels of serum erythropoietin due to suppression of the bone marrow by multiple intrauterine ...
Maier R F - - 1996
The need for red cell transfusions is reduced but not eliminated by recombinant human erythropoietin (rhEPO) in very low birthweight (VLBW) infants. To detect factors associated with the decision to transfuse VLBW infants during rhEPO treatment and to explain rhEPO 'non-responders', the subgroup of those 120 VLBW infants who were ...
Smith J J - - 1996
Despite an increased understanding of the cellular and molecular biology of the CFTR Cl- channel, it is not known how defective Cl- transport across airway epithelia causes chronic bacterial infections in cystic fibrosis (CF) airways. Here, we show that common CF pathogens were killed when added to the apical surface ...

In a double-blind placebo-controlled study we showed a 3-fold decrease in blood transfusions (BTFs) given to preterm infants with anaemia of prematurity who received recombinant erythropoietin. However, only 50% of placebo recipients required a BTF. Data from the placebo group indicated that either mean daily weight gain < or = ...
Ohto H - - 1996
BACKGROUND: Posttransfusion graft-versus-host disease (PT-GVHD) is underdiagnosed and underreported. Risk factors predisposing to PT-GVHD in newborn recipients, the clinical manifestations of the disease in newborns, and its mechanism are not well characterized. STUDY DESIGN and METHODS: A literature review identified 27 cases of PT-GVHD in newborns in Japan. Detailed information ...
Wang-Rodriguez J - - 1996
Small, premature infants require frequent small-volume transfusions. Traditional methods of transfusion expose these infants to multiple blood donors. It has recently been demonstrated that multiple donor exposures can be safely prevented in these infants by the assignment of fresh units to them and by the use of a sterile connecting ...

In the present study we assess the effect of recombinant human erythropoietin (r-HuEpo) upon levels of fetal Hb (HbF) and adult Hb (HbA) in preterm infants. Twenty-eight "healthy," appropriate for gestational age infants with birth weights 900-1400 g entered the study at 3 wk of age. Fourteen infants were randomized ...
Fain J - - 1995
BACKGROUND: Anemia of prematurity is invariably observed in very low birth weight infants and may become symptomatic enough to be treated with packed red cell transfusions. Recently, treatment of this condition with recombinant human erythropoietin has been advocated. STUDY DESIGN AND METHODS: To compare the costs of training symptomatic anemia ...
Druce M - - 1995
A 26-week gestation, premature neonate who developed a transient myeloproliferative disorder is presented. The morphological features of Down syndrome were not obvious at this gestational age, and the cytogenetic studies gave a misleading normal karyotype after the infant received non-irradiated blood. The diagnosis of Down syndrome was not made until ...

Clinically useful indicators of physiologically significant anemia requiring intervention have yet to be defined in the newborn. Finding a simple noninvasive marker of physiologically significant anemia remains elusive but is a laudable goal considering the risks of transfusion therapy and requirement for repeated parenteral (subcutaneous or IV) administration or r-HuEPO, ...
Chen J Y - - 1995
Seventy premature infants (birthweight 1.75 kg or less, gestational age 33 weeks or less) with hemoglobin less than 10 g/dL and hematocrit less than 30% were studied and randomly divided into three groups. All of them received oral elemental iron 3 mg/kg/day and vitamin E 5 mg/kg/day during the study ...

A 3-year survey of subaponeurotic haemorrhage (January 1991 to December 1993) in a tertiary referral centre in Hong Kong revealed that the incidence of this life-threatening condition was 6.4 per 1000 ventouse-associated deliveries, which is 60-fold more common than with other modes of childbirth. We highlight a lesser known phenomenon ...
Peterec S M - - 1995
Dramatic improvements have been made in the management of Rh disease. Anti-D immune globulin has reduced the incidence of Rh sensitization. Intrauterine transfusions have become routine to treat fetal anemia. Once an affected infant is born, several recent improvements in neonatal care have aided in the treatment of hyperbilirubinemia. These ...

The urinary excretion of cytomegalovirus (CMV) DNA, amplified by polymerase chain reaction using two pairs of primers for late antigen (LA) and major immediate-early antigen (MIE), and serum CMV IgM were examined in 85 pre-term infants (birth-weight less than 2000 g) on admission and monthly until 6 months after birth. ...
Dağoğlu T - - 1995
Rhesus haemolytic disease is a continuing problem in the newborn especially in countries where the use of anti-D immunoglobulin is not prevalent. The fetuses may need intrauterine transfusions to prevent hydrops faetalis and they also may need exchange transfusions to treat the hyperbilirubinaemia that develops after birth. These interventions expose ...
Luban N L - - 1995
The neonate who undergoes massive transfusion is at risk for transfusion-associated complications similar to the adult, but also faces some that are unique to the infant. By understanding the mechanics of the procedures that result in single or multiple blood volume exchange, the transfusion medicine physician can better assist his/her ...
Holman P - - 1995
There are many potential noninfectious complications that may be associated with the transfusion of blood products to the neonate. Most of these can be avoided by the careful preparation of the product according to current standards and the careful monitoring of the infant for metabolic changes during a transfusion. In ...
