Cjem. 2021
Abstract
INTRODUCTION Trauma resuscitation at dedicated trauma centers typically consist of ad-hoc teams performing critical tasks in a time-limited manner. This creates a high stakes environment apt or avoidable errors. Reporting of errors in trauma resuscitation is generally center-dependent and lacks common terminology. METHODS We conducted a systematic review by searching Ovid Medline, Scopus and Embase from inception to February 24, 2021 for errors in adult trauma resuscitation. English studies published after 2001 were included. Studies were assessed by two independent reviewers for meeting inclusion/exclusion criteria. Errors were characterized from the included studies and a summary table was developed. Our review was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42020152875). RESULTS The literature search retrieved 4658 articles with 26 meeting eligibility criteria. Errors were identified by morbidity and mortality rounds or other committee in 62%, missed injuries on tertiary assessment or radiology review in 12%, deviations from algorithmic guidelines in 12% or predefined for chest tube complications, critical incident reporting, aspiration or delays in care. In total there were 39 unique error types identified and divided into 9 categories including Emergency Medical Services handover, airway, assessment of injuries, patient monitoring and access, transfusion/blood related, management of injuries, team communication/dynamics, procedure error and disposition. CONCLUSIONS Overall, our systematic review identified 39 unique error types in trauma resuscitation. Identifying these errors is imperative in developing systems for improvement of trauma care.

Abstract
Background: Until now, transfusion-related acute lung injury (TRALI) has been considered to be the leading cause of blood transfusion-related diseases and death. And there is no clinically effective treatment plan for TRALI. The aim of this study was to systematically summarize the literature on risk factors for TRALI in critical patients.Methods: Electronic searches (up to March 2020) were performed in the Cochrane Library, Web of Knowledge, Embase, and PubMed databases. We included studies reporting on the risk factors of TRALI for critical patients and extracted the risk factors. Finally, thirteen studies met the inclusion criteria.Results: We summarized and analyzed the potential risk factors of TRALI for critical patients in 13 existing studies. The host-related factors were age (odds ratio (OR) [95% confidence interval] = 1.16 [1.08-1.24]), female sex (OR = 1.26 [1.16-1.38]), tobacco use status (OR = 3.82 [1.91-7.65]), chronic alcohol abuse (OR = 3.82 [2.97-26.83]), positive fluid balance (OR = 1.24 [1.08-1.42]), shock before transfusion (OR = 4.41 [2.38-8.20]), and ASA score of the recipients (OR = 2.72 [1.43-5.16]). The transfusion-related factors were the number of transfusions (OR = 1.40 [1.14-1.72]) and fresh frozen plasma (FFP) units (OR = 1.21 [1.01-1.46]). The device-related factor was mechanical ventilation (OR = 4.13 [2.20-7.76]).Conclusions: The risk factors for TRALI in this study included Number of transfusions and FFP units were positively correlated with TRALI. Age, female sex, tobacco use, chronic alcohol abuse, positive fluid balance, shock before transfusion, ASA score and mechanical ventilation may be potential risk factors for TRALI. Our study suggests that host-related risk factors may play a more important role in the occurrence and development of TRALI than blood transfusion-related risk factors.

Feeding Practices and Effects on Transfusion-Associated Necrotizing Enterocolitis in Premature Neonates
Killion E
Advances in neonatal care : official journal of the National Association of Neonatal Nurses. 2021
Abstract
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. FINDINGS Four studies did not demonstrate a reduction in transfusion-associated necrotizing enterocolitis (TANEC) with the implementation of feeding protocols during packed red blood cell (PRBC) transfusions. One study concluded that it could not confirm the benefit of withholding feeds during transfusion to reduce the risk of TANEC. A 2020 randomized controlled trial (RCT) found no difference in splanchnic oxygenation when enteral feeds are withheld, continued, or restricted during a PRBC transfusion. Holding feedings during PRBC transfusions did not result in adverse nutritional outcomes. IMPLICATIONS FOR PRACTICE To determine best evidence-based practice surrounding feeding protocols during RBC transfusions in very low-birth-weight and premature infants less than 37 weeks' gestation. IMPLICATIONS FOR RESEARCH It is recommended that large, multicentered, adequately powered RCTs be conducted in this area. Individual institutions should standardize their practice to improve quality, safety, and patient outcomes.

The Cochrane database of systematic reviews. 2020;11:Cd009280
Abstract
BACKGROUND Stroke is the second leading cause of death and a major cause of morbidity worldwide. Retrospective clinical and animal studies have demonstrated neuroprotective effects of iron chelators in people with haemorrhagic or ischaemic stroke. This is the first update of the original Cochrane Review published in 2012. OBJECTIVES To evaluate the effectiveness and safety of iron-chelating drugs in people with acute stroke. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (2 September 2019), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2019, Issue 9; 2 September 2019), MEDLINE Ovid (2 September 2019), Embase Ovid (2 September 2019), and Science Citation Index (2 September 2019). We also searched ongoing trials registers. SELECTION CRITERIA We included randomised controlled trials (RCTs) of iron chelators versus no iron chelators or placebo for the treatment of acute stroke, including subarachnoid haemorrhage. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results. We obtained the full texts of potentially relevant studies and evaluated them for eligibility. We assessed risk of bias using the Cochrane 'Risk of bias' tool, and the certainty of evidence using the GRADE approach. MAIN RESULTS Two RCTs (333 participants) were eligible for inclusion; both compared the iron-chelating agent deferoxamine against placebo. Both studies evaluated participants with spontaneous intracerebral haemorrhage. We assessed one study to have a low risk of bias; the other study had potential sources of bias. The limited and heterogeneous data did not allow for meta-analysis of the outcome parameters. The evidence suggests that administration of deferoxamine may result in little to no difference in deaths (8% in placebo vs 8% in deferoxamine at 180 days; 1 RCT, 291 participants; low-certainty evidence). These RCTs suggest that there may be little to no difference in good functional outcome (modified Rankin Scale score 0 to 2) between groups at 30, 90 and 180 days (placebo vs deferoxamine: 67% vs 57% at 30 days and 36% vs 45% at 180 days; 2 RCTs, 333 participants; low-certainty evidence). One RCT suggests that administration of deferoxamine may not increase the number of serious adverse events or deaths (placebo vs deferoxamine: 33% vs 27% at 180 days; risk ratio 0.81, 95 % confidence interval 0.57 to 1.16; 1 RCT, 291 participants; low-certainty evidence). No data were available on any deaths within the treatment period. Deferoxamine may result in little to no difference in the evolution of National Institute of Health Stroke Scale scores from baseline to 90 days (placebo vs deferoxamine: 13 to 4 vs 13 to 3; P = 0.37; 2 RCTs, 333 participants; low-certainty evidence). Deferoxamine may slightly reduce relative oedema surrounding intracerebral haemorrhage at 15 days (placebo vs deferoxamine: 1.91 vs 10.26; P = 0.042; 2 RCTs, 333 participants; low-certainty evidence). Neither study reported quality of life. AUTHORS' CONCLUSIONS We identified two eligible RCTs for assessment. We could not demonstrate any benefit for the use of iron chelators in spontaneous intracerebral haemorrhage. The added value of iron-chelating therapy in people with ischaemic stroke or subarachnoid haemorrhage remains unknown.

Abstract
INTRODUCTION Transfusion therapy in hemorrhaging trauma patients is associated with the development of thromboembolic events. It is unknown whether current resuscitation strategies, including large volumes of plasma and early administration of procoagulant therapy, increases this risk. METHODS A systematic search was conducted in MEDLINE, PubMed, and Embase. Studies were screened by two independent reviewers and included if they reported on thromboembolic events in patients with severe trauma (injury severity score ≥16) who received transfusion of at least 1 unit of red blood cells. The ratio by which blood products were transfused, as well as use of procoagulant or antifibrinolytic medication, was recorded. RESULTS A total of 40 studies with 11.074 bleeding trauma patients were included, in which 1.145 thromboembolic events were reported, yielding an incidence of 10% thromboembolic events. In studies performing routine screening for thromboembolic complications, the incidence ranged from 12% to 23%. The risk of thromboembolic events was increased after administration of tranexamic acid (TXA; odds ratio [OR], 2.6; 95% confidence interval [CI], 1.7-4.1; p < 0.001) and fibrinogen concentrate (OR, 2.1; 95% CI, 1.0-4.2; p = 0.04). Blood product ratio, the use of prothrombin complex concentrate or recombinant factor VIIa were not associated with thromboembolic events. CONCLUSION This systematic review identified an incidence of thromboembolic events of 10% in severely injured bleeding trauma patients. The use of TXA and fibrinogen concentrate was associated with the development of thromboembolic complications.

Critical care medicine. 2020;48(2):241-248
Abstract
OBJECTIVES RBC transfusions can increase oxygen availability to the tissues, but studies have provided conflicting results. The objectives of this study were, therefore, to evaluate, using systematic review and meta-analysis, the effects of transfusion on hemodynamic/oxygenation variables in patients without acute bleeding. DATA SOURCES PubMed, Scopus, Cochrane Database of Systematic Reviews, and Embase from inception until June 30, 2019. STUDY SELECTION All articles that reported values of prespecified hemodynamic or oxygenation variables before and after RBC transfusion. DATA EXTRACTION Publication year, number of patients, number of transfusions and the type of population studied, hemodynamic and oxygenation data (heart rate, cardiac index, mixed venous oxygen saturation or central venous oxygen saturation, oxygen delivery index, oxygen consumption index, oxygen extraction ratio, arteriovenous oxygen difference and arterial blood lactate) before and after transfusion. We performed a meta-analysis for each variable for which there were sufficient data to estimate mean differences. We also performed subgroup analyses comparing septic with nonseptic patients. DATA SYNTHESIS We retrieved 6,420 studies; 33 met the inclusion criteria, 14 of which were in patients with sepsis. In the meta-analysis, the estimated mean differences and 95% CIs comparing the periods before and after transfusion were -0.0 L/min/m (-0.1 to 0.1 L/min/m) (p = 0.86) for cardiac index; -1.8 beats/min (-3.7 to 0.1 beats/min) (p = 0.06) for heart rate; 96.8 mL/min/m (71.1-122.5 mL/min/m) (p < 0.01) for oxygen delivery index; 2.9% (2.2-3.5%) (p < 0.01) for mixed venous oxygen saturation or central venous oxygen saturation; -3.7% (-4.4% to -3.0%) (p < 0.01) for oxygen extraction ratio; and 4.9 mL/min/m (0.9-9.0 mL/min/m) (p = 0.02) for oxygen consumption index. The estimated mean difference for oxygen consumption index in the patients with sepsis was 8.4 mL/min/m (2.3-14.5 mL/min/m; p = 0.01). CONCLUSIONS Transfusion was not associated with a decrease in mean cardiac output or mean heart rate. The increase in mean oxygen delivery following transfusion was associated with an increase in mean oxygen consumption after transfusion, especially in patients with sepsis.

Transfusion-Associated Circulatory Overload in ICUs: A Scoping Review of Incidence, Risk Factors, and Outcomes
De Cloedt L, Savy N, Gauvin F, Taylor S, Lacroix J, Emeriaud G
Critical care medicine. 2019
Abstract
Transfusion-associated circulatory overload is the most frequent serious adverse transfusion reaction, with an incidence close to 1% of transfused patients in the general adult population. Patients in ICUs are probably more at risk of transfusion-associated circulatory overload as they are more frequently transfused and associated with more comorbidities. However, the epidemiology of transfusion-associated circulatory overload in ICU is not well characterized, leading to a risk of underdiagnosis. OBJECTIVES We conducted a scoping review to describe the incidence, risk factors, and outcomes of transfusion-associated circulatory overload in PICU and adult ICU. DATA SOURCES PubMed, Ovid Medline, Ovid All EBM Reviews, Ovid Embase, and EBSCO CINAHL COMPLETE. STUDY SELECTION Two reviewers independently screened each article for inclusion criteria. Studies were eligible if they reported data on incidence, risk factors, or outcomes of transfusion-associated circulatory overload in at least 10 ICU patients. DATA SYNTHESIS Among 5,926 studies identified, nine were included. Five studies were prospective, and four were retrospective. The definition of transfusion-associated circulatory overload varied among studies. The pooled incidence of transfusion-associated circulatory overload was of 5.5% (95% CI, 2.6-9.4%) in adult ICUs (four studies, 2,252 patients, high heterogeneity). In PICUs, two studies (345 patients) reported 0 cases, and a third study (136 patients) reported variable incidences between 1.5% and 76%, depending on diagnostic criteria. Risk factors for transfusion-associated circulatory overload included positive fluid balance, the number and type of products transfused, rate of transfusion, and cardiovascular and renal comorbidities. Transfusion-associated circulatory overload was associated with increased ICU and hospital lengths of stay, whereas the association with mortality was not consistent. CONCLUSIONS Transfusion-associated circulatory overload is frequent in ICU patients and is associated with adverse outcomes. The lack of a pediatric-adjusted definition of transfusion-associated circulatory overload may lead to a risk of underdiagnosis of this condition in PICUs. Further research is warranted to improve the knowledge of transfusion-associated circulatory overload and the safety of transfusion in ICU patients.

Abstract
Limited evidence exists to support the withholding of feeds during packed red blood cell (PRBC) transfusion to reduce the incidence of transfusion-associated necrotizing enterocolitis (TANEC) in preterm infants. The aim of the manuscript was to systematically review studies reporting the effect of implementing a policy of withholding feeds on the incidence of TANEC in preterm infants. The following databases were searched for relevant studies published between the databases' inception and December 2016: PubMed, Embase, the Cochrane Central Register of Controlled Trials, the Cumulative Index of Nursing and Allied Health Literature, and Pediatric Academic Societies Abstract Archive. Other relevant sources were also searched. There were no restrictions on study design. Studies reporting on the incidence of TANEC (stage ≥2 necrotizing enterocolitis within 48-72 h) after implementation of a policy of withholding feeds in the peritransfusion period in preterm infants were included. This meta-analysis used a random-effects model with assessment of quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. There were no randomized controlled trials (RCTs). Pooled results from 7 non-RCTs (n = 7492) showed that withholding feeds during PRBC transfusion significantly reduced the incidence of TANEC (RR: 0.47; 95% CI: 0.28, 0.80; P = 0.005; I2 = 11%). The overall quality of evidence was moderate on GRADE analysis. These findings suggest that withholding feeds during the peritransfusion period may reduce the risk of TANEC in preterm infants. Adequately powered RCTs are needed to confirm these findings.

Risk factors for trauma-induced coagulopathy and transfusion-associated multiple organ failure in severely injured trauma patients
Balvers K, Wirtz MR, van Dieren S, Goslings JC, Juffermans NP
Frontiers in Medicine. 2015;2:24
Abstract
BACKGROUND Both trauma-induced coagulopathy (TIC) and transfusion strategies influence early outcome in hemorrhagic trauma patients. Their impact on late outcome is less well characterized. This study systematically reviews risk factors for TIC- and transfusion-associated multiple organ failure (MOF) in severely injured trauma patients. MATERIALS AND METHODS A systematic search was conducted in PubMed and Embase. Studies published from 1986 to 2013 on adult trauma patients with an injury severity score >16, investigating TIC or transfusion strategies with MOF as primary or secondary outcome, were eligible for inclusion. Results of the included studies were evaluated with meta-analyses of pooled data. RESULTS In total, 50 studies were included with a total sample size of 63,586 patients. Due to heterogeneity of the study populations and outcome measures, results from 7 studies allowed for pooling of data. Risk factors for TIC-associated MOF were hypocoagulopathy, hemorrhagic shock, activated protein C, increased histone levels, and increased levels of markers of fibrinolysis on admission. After at least 24h after admission, the occurrence of thromboembolic events was associated with MOF. Risk factors for transfusion-associated MOF were the administration of fluids and red blood cell units within 24h post-injury, the age of red blood cells (>14days) and a ratio of FFP:RBC>1:1 (OR 1.11, 95% CI 1.04-1.19). CONCLUSION Risk factors for TIC-associated MOF in severely injured trauma patients are early hypocoagulopathy and hemorrhagic shock, while a hypercoagulable state with the occurrence of thromboembolic events later in the course of trauma predisposes to MOF. Risk factors for transfusion-associated MOF include administration of crystalloids and red blood cells and a prolonged storage time of red blood cells. Future prospective studies investigating TIC- and transfusion-associated risk factors on late outcome are required.

Transfusion-associated hyperkalemic cardiac arrest in pediatric patients receiving massive transfusion
Lee AC, Reduque LL, Luban NL, Ness PM, Anton B, Heitmiller ES
Transfusion. 2014;54((1):):244-54.
Abstract
BACKGROUND Hyperkalemic cardiac arrest is a potential complication of massive transfusion in children. Our objective was to identify risk factors and potential preventive measures by reviewing the literature on transfusion-associated hyperkalemic cardiac arrest (TAHCA) in the pediatric population. STUDY DESIGN AND METHODS Literature searches were performed in MEDLINE and the Cochrane Database of Systematic Reviews. RESULTS We identified nine case reports of pediatric patients who had experienced cardiac arrest during massive transfusion. Serum potassium concentration was reported in eight of those reports; the mean was 9.2+1.8mmol/L. Risk factors for TAHCA noted in the case reports included infancy (n=6); age of red blood cells (RBCs; n=5); site of transfusion (n=5); and the presence of comorbidities such as hyperkalemia, hypocalcemia, acidemia, and hypotension (n=9). We also identified 13 clinical studies that examined potassium levels associated with transfusion. Of those 13, five studied routine transfusion, two were registries, and six examined massive transfusion. CONCLUSIONS Key points identified from this literature search are as follows: 1) Case reports are skewed toward infants and neonates in particular and 2) the rate of blood transfusion, more so than total volume, cardiac output, and the site of infusion, are key factors in the development of TAHCA. Measures to reduce the risk of TAHCA in young children include anticipating and replacing blood loss before significant hemodynamic compromise occurs, using larger-bore (>23-gauge) peripheral intravenous catheters rather than central venous access, checking and correcting electrolyte abnormalities frequently, and using fresher RBCs for massive transfusion. 2013 American Association of Blood Banks.
