Cardiorespiratory monitoring of red blood cell transfusions in preterm infants. Eur J Pediatr 2022; 181:489-500. [PMID: 34370081 PMCID: PMC8821053 DOI: 10.1007/s00431-021-04218-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 07/19/2021] [Accepted: 07/20/2021] [Indexed: 11/21/2022]
Abstract
Clinical improvement after red blood cell (RBC) transfusions in preterm infants remains debated. This study aims to investigate the effect of RBC transfusion on the occurrence of desaturations and hypoxia, and other cardiorespiratory outcomes in preterm infants. In this longitudinal observational study, prospectively stored cardiorespiratory parameters of preterm infants who received at least one RBC transfusion between July 2016 and June 2017 were retrospectively analyzed. Sixty infants with 112 RBC transfusions, median GA of 26.7 weeks, were included. The number of desaturations and area < 80% SpO2 limit, as a measure of the hypoxic burden, were calculated in 24 h before and after RBC transfusion. A mixed effects model was used to account for repeated measurements. Overall, the mean (SE) number of desaturations per hour decreased from 3.28 (0.55) to 2.25 (0.38; p < 0.001), and area < 80% SpO2 limit decreased from 0.14 (0.04) to 0.08 (0.02) %/s (p = 0.02). These outcomes were stratified for the number of desaturations in 24 h prior to RBC transfusion. The largest effect was observed in the group with the highest mean number of desaturations (≥ 6) prior to RBC transfusion, with a decrease from 7.50 (0.66) to 4.26 (0.38) (p < 0.001) in the number of desaturations and 0.46 (0.13) to 0.20 (0.06) in the area < 80% SpO2. Perfusion index increased significantly after RBC transfusion (p < 0.001). No other significant effects of RBC transfusion on cardiorespiratory data were observed.Conclusions: RBC transfusions in preterm newborns could help decrease the incidence of desaturations and the area < 80% SpO2 as a measure of the hypoxic burden. The higher the number of desaturations prior to the RBC transfusion, the larger the effect observed. What is Known: •Red blood cell transfusions potentially prevent hypoxia in anemic preterm infants by increasing the circulatory hemoglobin concentration and improving tissue oxygenation. •There is not a predefined hemoglobin concentration cut-off for the occurrence of symptomatic anemia in preterm infants. What is New: •Oxygen desaturations and hypoxia in anemic preterm infants can be improved by RBC transfusions, especially if more desaturations have occurred before transfusion. •Cardiorespiratory monitor data may help identify infants who will benefit most from red blood cell transfusions.

Red Cell Transfusion Practices in Neonatal Intensive Care Unit: An Experience from Tertiary Care Centre. Indian J Hematol Blood Transfus 2018; 34:671-676. [PMID: 30369739 DOI: 10.1007/s12288-018-0959-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Accepted: 04/07/2018] [Indexed: 10/17/2022] Open
Abstract
Red cells are the most often transfused blood components during the neonatal period. The aim of the present study was to obtain information regarding the relationship of red cell transfusion with clinical outcomes and to evaluate red cell transfusion practices in neonatal centre of a tertiary care centre. The clinical history, blood component details and laboratory parameters were evaluated with clinical outcomes. The neonates requiring transfusion of red cells were then followed up in the Blood bank for various laboratory parameters. Clinical parameters and clinical outcome were noted from case files. During the study period, 291 neonates were admitted in NICU. 2 neonates were excluded as they were congenitally malformed. Out of 289 admitted neonates, 61 neonates (21.1%) received blood and blood component transfusions. Out of 61 neonates, 20 received red cell transfusions. Mean donor exposure of red cells was 1.2. The mean volume of transfused red cell was 39.6 ml with mean age of red cells was 3.6 days. The mean pre- and post-transfusion Hct was 25.3 and 30.4%, respectively. The most common indication for red cell transfusion was low haemoglobin. There was a significant increase in lactate level and decrease in base excess in transfused neonates. However, no statistically significant correlations were found between transfusions and neonatal weight gain, apnoea, respiratory support and mortality. Transfusion of red cells has significant effect on laboratory parameters as compared to clinical parameters such as weight gain, episodes of apnoea and respiratory support.

Abstract
BACKGROUND: Lack of recent studies focusing on indications, pattern, and benefits of transfusions in low birth weight (B.Wt) and low gestational age (GA) preterm neonates prompted us to undertake this study. AIM: To estimate the transfusion requirements and outcomes in preterm neonates <1500 g and/or <32 weeks. SETTINGS AND DESIGN: This is a cross-sectional study conducted over a period of 2 years in a tertiary care center. MATERIALS AND METHODS: This study was conducted with 101 preterm neonates <1500 g and/or <32 weeks who received blood transfusions in the Neonatal Intensive Care Unit. Restrictive pattern of transfusion was followed. Demographic details and antenatal, neonatal, laboratory, and transfusion parameters were collected. STATISTICAL ANALYSIS USED: Statistical analyses were performed using SPSS 16. RESULTS: The study participants received 311 transfusions. Transfusion requirements decreased with increasing GA and B.Wt. Majority of blood transfusions occurred during the first 2 weeks of life. Packed red blood cells (PRBCs) were the most frequent blood components transfused. Ninety-six percent of the study population had an uneventful transfusion. Mean hemoglobin improvement after PRBC transfusions was 2.3 ± 2.1 g/dl. Improvement in apnea occurred in 76% PRBC transfusions. Infants with sepsis, patent ductus arteriosus, bronchopulmonary dysplasia, disseminated intravascular coagulation, and dyselectrolytemia received more number of transfusions. CONCLUSION: This study would serve as an audit for neonatal blood transfusion therapy. Close adherence to neonatal transfusion policy and restrictive transfusion guidelines helps reduce inappropriate use of blood products and adverse transfusion reactions.

Abstract
The current evidence regarding the indication, advantages and risks of red blood cell transfusion (RBCT) for preterm infants is discussed. This is an important area in Neonatology to be examined given that 90% of extremely low birth weight infants receive RBCT and many controversies remain regarding when to transfuse and the risks of RBCT. The various treatment thresholds and guidelines used are presented and we compare the short-term clinical benefits of liberal and restrictive RBCT in preterm infants; the majority of these are equivocal and sadly long-term outcome data is limited. The latest evidence on how anaemia and blood transfusion affect organ perfusion in preterm infants is presented. This is important when trying to establish the optimal trigger threshold for RBCT in preterm infants, especially because the knowledge about the adaptive physiological responses to anaemia in very low birth weight infants and the effects of RBCT at various levels of anaemia is also inadequate. Further research into the physiological adaptive response to anaemia of varying degrees and to RBCT at different levels of anaemia in preterm infants of different gestational and post-natal ages is needed before we can conclusively guide the optimal timing and trigger thresholds for RBCT in preterm infants.

Packed red blood cell transfusions as a risk factor for parenteral nutrition associated liver disease in premature infants. World J Clin Pediatr 2016; 5:365-369. [PMID: 27872824 PMCID: PMC5099588 DOI: 10.5409/wjcp.v5.i4.365] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2016] [Revised: 08/13/2016] [Accepted: 10/24/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To determine if packed red blood cell transfusions contribute to the development of parenteral nutrition associated liver disease.
METHODS A retrospective chart review of 49 premature infants on parenteral nutrition for > 30 d who received packed red blood cell (PRBC) transfusions was performed. Parenteral nutrition associated liver disease was primarily defined by direct bilirubin (db) > 2.0 mg/dL. A high transfusion cohort was defined as receiving > 75 mL packed red blood cells (the median value). Kaplan-Meier plots estimated the median volume of packed red blood cells received in order to develop parenteral nutrition associated liver disease.
RESULTS Parenteral nutritional associated liver disease (PNALD) was noted in 21 (43%) infants based on db. Among the 27 high transfusion infants, PNALD was present in 17 (64%) based on elevated direct bilirubin which was significantly greater than the low transfusion recipients. About 50% of the infants, who were transfused 101-125 mL packed red blood cells, developed PNALD based on elevation of direct bilirubin. All infants who were transfused more than 200 mL of packed red blood cells developed PNALD. Similar results were seen when using elevation of aspartate transaminase or alanine transaminase to define PNALD.
CONCLUSION In this retrospective, pilot study there was a statistically significant correlation between the volume of PRBC transfusions received by premature infants and the development of PNALD.

Abstract
BACKGROUND Data on age of blood and its impact on donor exposure and inventory in the paediatric setting are lacking. The standard of practice of reserving a specific red blood cell (RBC) unit for neonates who may require repeat transfusions is unique to the paediatric setting. Requiring transfusion of fresher RBC units may increase the exposure of neonates to multiple units and negatively affect the supply of fresh RBC. We constructed a transfusion model based on a 6 months of retrospective neonatal transfusion data at our institution. MATERIALS AND METHODS All neonates (≤4 months old) at Texas Children's Hospital who received a RBC transfusion from June to November 2011 were included and RBC transfusion data were compiled. The age of blood at the time of each RBC transfusion was recorded. These data were reviewed to calculate exposure and inventory impact if each transfusion had been restricted to RBC either ≤7 or ≤14 days old at transfusion. RESULTS A total of 216 neonates received 938 RBC transfusions. Of these, 393 (42%) were fresh RBC (≤14 days old), even without a required age guideline. Requiring fresh (≤14 days) RBC for all transfusions in this period would have resulted in 70 additional fresh units and one or more additional exposures in 44 patients. Requiring fresher (≤7 days old) RBC would have resulted in an additional 147 units and. one or more additional exposures in 54 patients. DISCUSSION The more conservative model of fresh (≤7 days old) RBC would greatly increase fresh RBC inventory requirements, and 25% of transfused neonates would require additional RBC exposure. Based on retrospective data and the two transfusion models, it can be concluded that requiring RBC ≤14 days old for neonatal transfusion would best balance the use of fresher RBC with the smallest increase in patient exposure (20%) and minimum impact on the RBC inventory.

Abstract
Background: Hemovigilance is a series of surveillance procedures encompassing the entire transfusion chain from the collection of blood and its components to the follow-up of its recipients. It is intended to collect and access information on unanticipated or adverse effects stemming from the therapeutic use of labile blood products. Blood transfusion, particularly in neonates, requires meticulous clinical assessment to ensure safety before, during, and after the procedure. Therefore, it is essential to investigate how nurses and other health care providers implement hemovigilance with a view to elevating the standards of care. Objectives: The aim of this study, conducted between 2013 and 2014, was to assess nursing care regarding hemovigilance in the neonatal wards and neonatal intensive care units (NICUs) of selected hospitals affiliated to Shahid Beheshti University of Medical Sciences. Materials and Methods: This descriptive study assessed nursing care concerning hemovigilance in 144 neonates. Data were collected using a checklist at the neonatal wards and NICUs of Mahdiyeh, Mofid, and Imam Hussain hospitals affiliated to Shahid Beheshti University of Medical Sciences. The checklist contained information on the standard of care in relation to neonatal hemovigilance in three components of request, transfusion, and documentation. Descriptive statistics with the Statistical Package for the Social Sciences (version 21) were used to analyze the collected data. Results: The rates of compliance with the hemovigilance guidelines in terms of request, transfusion, and documentation were 47%, 63.2%, and 68%, correspondingly, with a total score of 59.6% in all areas of research. Accordingly, compliance with hemovigilance guidelines was highest in documentation (68%), followed by transfusion (63.2%) and request (47%). Conclusions: The overall score of nursing care as regards adherence to the neonatal hemovigilance guidelines was 59.6% in the present study, indicating a lack of care and failure in training in this regard.

Abstract
Objective Newborn infants are the most heavily transfused population inside intensive care units. The hemoglobin level used to indicate the need of transfusions is not well established. The aim of this study was to evaluate transfusional practices in newborns in the neonatal intensive care units of one specific city. Methods Red blood cell transfusion practices of all transfused newborns in all five of the neonatal intensive care units of the city were analyzed. Data are reported as descriptive statistics, including numbers and percentages and means and standard deviation. Univariate analysis, followed by stepwise logistic regression was performed in respect to transfusional data and outcomes. Results A total of 949 patients were admitted to the intensive care units during the 12-month study period with 20.9% receiving at least one transfusion, most (62.4%) of whom received more than one transfusion. The mean number of transfusions per infant was 2.7 ± 2.16; in the liberal transfusion group the mean number was 1.59 ± 1.63 and in the restrictive group it was 1.08 ± 1.51. The mean hemoglobin and hematocrit levels were 9.0 g/dL (±1.4 g/dL) and 27.4% (±4.3%), respectively. The most common indications for blood transfusions were sepsis and prematurity. Conclusion This study shows that the characteristics and the transfusion practices for newborns admitted in the neonatal intensive care units of Juiz de Fora are similar to recent pubications. There was no significant reduction in the number of transfusions per child in the restrictive group compared to the liberal group. Restrictive transfusions are an independent risk factor for peri-intraventricular hemorrhages and death.
