Abstract
BACKGROUND Children with thalassemia are generally dependent on blood transfusions and face a lot of stress and alteration in their physiological parameters through the procedure. AIM: This study aimed to investigate the effect of Benson's relaxation technique versus music intervention on physiological parameters and stress of children with thalassemia during blood transfusions. DESIGN A randomized, controlled trial with three parallel groups. METHODS One hundred and twenty preschool-age children with thalassemia who underwent blood transfusions were randomly assigned to three groups. Children of the control group received only routine hospital care through blood transfusions. Music intervention group children listened to recorded Mozart's music and children of Benson's relaxation group received relaxation intervention before and during the blood transfusions. Outcome measures were physiological parameters and behavioral distress levels. SETTING Hematology outpatient clinic of the Children's University Hospital at El-Shatby in Alexandria from October 2022 to February 2023. RESULTS The mean total score of children's behavioral responses to stress before the blood transfusions procedure was 19.32 ± 4.08, 14.20 ± 0.93, and 16.92 ± 4.74 in the control, music, and Benson groups, respectively. Beyond that, there was a decline in their physiological parameters and behavioral stress response during and after procedure among groups of study (P = 0.005 & <0.001, respectively). CONCLUSION Music and Benson's relaxation interventions had a helpful effect on stabilizing the physiological parameters and reducing behavioral distress levels in children with thalassemia undergoing blood transfusions. PRACTICE IMPLICATIONS This study directs paediatric nurses to apply Benson's relaxation and music interventions for children with thalassemia to enhance their responses.

Acta paediatrica (Oslo, Norway : 1992). 2023
Abstract
AIM: To determine if trial-related blood sampling increases the risk of later red-blood-cell (RBC) transfusion in very preterm infants, we compared the volume of clinical- and trial-related blood samples, in a specific trial and correlated to subsequent RBC transfusion. METHODS For 193 very preterm infants, participating in the FortiColos trial (NCT03537365), trial-related blood volume drawn was in accordance to ethical considerations established by the European Commission. Medical records were reviewed to assess the number and cumulated volume (mL/kg) of blood samples (both clinical- and trial-related). Data were compared with need of RBC transfusions during the first 28days of life. RESULTS Mean (SD) gestational age and bith weight was 28 ± 1 weeks and 1168 ± 301 g. In total, 11% of total blood volume was drawn for sampling (8.1 ± 5.1 mL/kg) and trial-related sampling accounted for 1.6 ± 0.6 mL/kg. Trial-related blood sampling had no impact on RBC transfusion (p=0.9). CONCLUSION Clinical blood sampling in very preterm infants is associated with blood loss and subsequent need for RBC transfusions. In a specific trial requiring blood samples, we found no additional burden of trial-related blood sampling. The study suggest that trial-related sampling is safe if European criteria are followed.

Abstract
OBJECTIVES Extracorporeal membrane oxygenation (ECMO) involves complex coagulation management and frequent hemostatic complications. ECMO practice between centers is variable. To compare results between coagulation studies, standardized definitions and clear documentation of ECMO practice is essential. We assessed how study population, outcome definitions, and ECMO-, coagulation-, and transfusion-related parameters were described in pediatric ECMO studies. DATA SOURCES Embase, Medline, Web of Science, Cochrane Library and Google Scholar. STUDY SELECTION English original studies of pediatric ECMO patients describing hemostatic tests or outcome. DATA EXTRACTION Eligibility was assessed following PRISMA guidelines. Study population, outcome and ECMO-, coagulation, and transfusion parameters were summarized. DATA SYNTHESIS A total of 107 of 1312 records were included. Study population parameters most frequently included (gestational) age (79%), gender (60%), and (birth) weight (59%). Outcomes, including definitions of bleeding (29%), thrombosis (15%), and survival (43%), were described using various definitions. Description of pump type, oxygenator and cannulation mode occurred in 49%, 45%, and 36% of studies, respectively. The main coagulation test (53%), its reference ranges (49%), and frequency of testing (24%) were the most prevalent reported coagulation parameters. The transfusion thresholds for platelets, red blood cells, and fibrinogen were described in 27%, 18%, and 18% of studies, respectively. CONCLUSIONS This systematic review demonstrates a widespread lack of detail or standardization of several parameters in coagulation research of pediatric ECMO patients. We suggest several parameters that might be included in future coagulation studies. We encourage the ECMO community to adopt and refine this list of parameters and to use standardized definitions in future research.

Abstract
INTRODUCTION Shock-index (SI) and systolic blood pressure (SBP) are metrics for identifying children and adults with hemodynamic instability following injury. The purpose of this systematic review was to assess the quality of these metrics as predictors of outcomes following pediatric injury. MATERIALS AND METHODS We conducted a literature search in Pubmed, SCOPUS, and CINAHL to identify studies describing the association between shock metrics on the morbidity and mortality of injured children and adolescents. We used the data presented in the studies to calculate the sensitivity and specificity for each metric. This study was registered with Prospero, protocol CRD42020162971. RESULTS Fifteen articles met the inclusion criteria. seven studies evaluated SI or SIPA score, an age-corrected version of SI, as predictors of outcomes following pediatric trauma, with one study comparing SIPA score and SBP and one study comparing SI and SBP. The remaining eight studies evaluated SBP as the primary indicator of shock. The median sensitivity for predicting mortality and need for blood transfusion was highest for SI, followed by SIPA, and then SBP. The median specificity for predicting these outcomes was highest for SBP, followed by SIPA, and then SI. CONCLUSIONS Common conclusions were that high SIPA scores were more specific than SI and more sensitive than SBP. SIPA score had better discrimination for severely injured children compared to SI and SBP. An elevated SIPA was associated with a greater need for blood transfusion and higher in-hospital mortality. SIPA is specific enough to exclude most patients who do not require a blood transfusion.

Abstract
BACKGROUND Trial outcomes should be relevant to all stakeholders, and allow assessment of interventions' efficacy and safety at appropriate timeframes. There is no consensus regarding outcome measures in the growing field of pre-hospital trauma transfusion research. Harmonization of future clinical outcome reporting is key to facilitate inter-study comparisons and generate cohesive, robust evidence to guide practice. OBJECTIVES To evaluate outcome measures reported in pre-hospital trauma transfusion trials. METHODS Data Sources, Eligibility Criteria, Participants and InterventionsWe conducted a scoping systematic review to identify the type, number and definitions of outcomes reported in randomised controlled trials, prospective and retrospective observational cohort studies investigating pre-hospital blood component transfusion in adult and paediatric patients with traumatic haemorrhage. Electronic database searching of PubMed, Embase, Web of Science, Cochrane, OVID, clinical trials.gov, and the Transfusion Evidence Library was completed in accordance with PRISMA guidelines.Study Appraisal and Synthesis MethodsTwo review authors independently extracted outcome data. Unique lists of salutogenic (patient-reported health and wellbeing outcomes) and non-salutogenic focused outcomes were established. RESULTS 3,471 records were identified. 34 studies fulfilled inclusion criteria: four military (n = 1,566 patients) and 30 civilian (n = 14,398 patients), all between 2000 and 2020. 212 individual non-patient-reported outcomes were identified, which collapsed into 20 outcome domains with varied definitions and timings. All primary outcomes measured effectiveness, rather than safety or complications. 69% reported mortality, with 11 different definitions. No salutogenic outcomes were reported. LIMITATIONS The review is limited by a lack of high-grade prospective comparative trials with clear predefined primary outcomes. CONCLUSION AND IMPLICATIONS OF KEY FINDINGS There is heterogeneity in outcome reporting and definitions, an absence of patient-reported outcome, and an emphasis on clinical effectiveness rather than safety or adverse events in pre-hospital trauma transfusion trials. We recommend stakeholder consultation and a Delphi process to develop a clearly defined minimum core outcome set for pre-hospital trauma transfusion trials. SYSTEMATIC REVIEW REGISTRATION NUMBER This review was prospectively registered with PROSPERO (CRD42019131406). LEVEL OF EVIDENCE II. STUDY TYPE Scoping Systematic Review.

Frontiers in pediatrics. 2020;8:612467
Abstract
Background: Despite advances in technology and clinical experience, the incidence of hemostatic complications, including bleeding and thrombosis, remains high in children supported with extracorporeal membrane oxygenation (ECMO). These hemostatic complications are important to prevent, since they are associated with increased morbidity and mortality. This systematic literature review aims to outline the most important risk factors for hemostatic complications in children undergoing ECMO treatment, to summarize the reported alternative anticoagulant drugs used in pediatric ECMO and to describe studied associations between coagulation tests and hemostatic complications. Methods: A literature search was performed in Embase, Medline, Web of Science Core Collection, Cochrane Central Register of Controlled Trials, and Google Scholar in February 2020. Included studies were studies evaluating children (<18 years old) treated with ECMO, and studies evaluating risk factors for hemostatic complications, alternative anticoagulants, or the association between coagulation tests and hemostatic complications. Results: Out of 1,152 articles, 35 studies were included. Thirteen out of 49 risk factors were investigated in three or more studies. Most consistent results were found regarding ECMO duration and pH. However, evidence for risk factors was equivocal in the majority of studies, which is explained by the variability of populations studied, definitions of hemostatic complications, ECMO circuits, anticoagulation protocols, transfusion triggers and monitoring of anticoagulation. Five studies described alternative anticoagulants, including bivalirudin (n = 3), argatroban (n = 1) and FUT (n = 1). Higher anti-factor Xa levels were associated with less clotting events in one of nine studies, investigating the association between tests and hemostatic complications. Two studies revealed an association between anti-factor Xa assay-based protocols and a decreased number of transfusions, bleedings and need for circuit change. Conclusion: Studies regarding risk factors showed conflicting results and a few retrospective studies reported the use of new anticoagulants and data on coagulation tests in relation to hemostatic complications. To decrease hemostatic complications in ECMO children, prospective multicenter studies are needed with clear bleeding and thrombotic definitions, and the best possible standardization of ECMO circuits used, anticoagulation protocols, and transfusion triggers.

The Journal of pediatrics. 2019
Abstract
OBJECTIVE To evaluate the effect of blood sampling from the placental end of the umbilical cord compared with initial blood sampling from neonates, on the need for first packed red blood cell transfusion in extremely preterm infants. We hypothesized that cord blood sampling could delay the time to first blood transfusion. STUDY DESIGN In this single-center, assessor blind, randomized controlled trial, we included extremely low birth weight neonates <28 weeks of gestational age at birth. Five milliliter of blood for initial laboratory investigations was collected either from the placental end of the umbilical cord (study group) or from the neonate upon neonatal intensive care unit admission (control group). Both groups received similar anemia prevention strategies. The primary outcome was the time (in days) to the first packed red blood cell transfusion, and was compared using survival analysis. RESULTS Eighty neonates were enrolled. The time to first transfusion was significantly delayed in the cord sampling group (30 vs 14 days, hazard ratio: 0.44, [95% CI 0.27-0.72], P < .001). Fewer neonates in the cord sampling group were transfused in the first 28 days of life (30% vs 75%, P < .001). Overall transfusion requirements and other clinical outcomes were similar in the groups. CONCLUSIONS Initial blood sampling from placental end of umbilical cord, when combined with anemia prevention strategies, significantly prolonged the time to first transfusion and reduced the need for early transfusions among extremely premature neonates.

Abstract
PURPOSE/OBJECTIVES To determine whether infusion method influences the quality of platelets transfused. DESIGN Linked in vitro and in vivo study. Quasi-experimental design for in vitro and cross-over design with balanced randomization for in vivo. SETTING Pediatric cancer center in the midsouthern United States. SAMPLE Pheresed/pooled platelet units in vitro (n = 12). In vivo convenience sample of 26 children, ages 2-19 years, with cancer and thrombocytopenia who required platelet transfusion. METHODS Two infusion pumps (IMED 980 and Gemini, IMED Corp., San Diego, CA) versus gravity flow for in vitro platelet infusion. Gemini infusion pump versus gravity flow for in vivo platelet transfusion. MAIN OUTCOME MEASURES Platelet count, morphology score, and corrected count increment. FINDINGS No significant differences noted in platelet count or morphology score among or across the three infusion methods in vitro. No significant differences noted between the two infusion methods in platelet count or corrected count increment in vivo. CONCLUSIONS Although limited to a specific patient population, setting, and infusion device, findings revealed that the pump was clinically acceptable because it did not negatively affect platelet recovery. Replication of this study with other infusion devices is recommended. IMPLICATIONS FOR NURSING PRACTICE Study findings validate the current nursing procedure for the administration of platelets at the study setting. Use of infusion pumps for platelet transfusions is time-efficient and energy-efficient for nurses because the pumps offer a well-controlled infusion rate, accurate volume measurement, and an alarm system for monitoring the infusion.
