Degueldre, J., Dessy, E., T'Sas, F., Deneys, V.
Blood transfusion = Trasfusione del sangue. 2024
Abstract
BACKGROUND Blood supply problems in remote areas are well known. To overcome this shortage, many countries have developed innovative Walking Blood Bank (WBB) protocols. However, no common standards have yet been set for their use and common actions. Given that these procedures involve a certain risk, it would be interesting to analyse the activating criteria that lead to using this unusual protocol. Thus, this review aimed to identify indications for a WBB and the common risk mitigation measures. MATERIAL AND METHODS This PRISMA-compliant review only included studies published from 1985 to 25(th) of January 2023 that describe adult male military casualties requiring blood transfused locally using a walking blood transfusion protocol. All relevant data (i.e., activation and contextual factors and risk mitigation measures) were tabulated to retrieve information from the selected military studies. RESULTS Our results indicated that activation criteria were homogeneous across the 12 reviewed studies. Whole blood was collected from a WBB when there was a shortage of blood products and when platelets were needed. In the literature reviewed, the main risks associated with such a protocol, namely hemolytic adverse events and transfusion transmitted diseases, are mitigated by the use of typing and screening measures if they are reported. However, there is less consistency in the implementation of those risk mitigation measures. DISCUSSION This unusual protocol needs to be integrated into the medical support plan until conventional transfusion support can take over, and should include on-site blood collection from a donor, whether a WBB or an emergency donor panel. The benefits of such a protocol outweigh the risks in a life-threatening situation, especially since these risks can be anticipated and minimised by planning to pre-screen all potential donors before their deployment. Finally, educating and training the staff who must implement this unusual procedure can also improve the safety and survival rate of future patients.

Study on the Effectiveness and Value of Evidence-Based Nursing and Predictive Nursing in Emergency Treatment of Upper Gastrointestinal Bleeding
Yang, Y., Li, Z., He, Y., Xu, M.
Alternative therapies in health and medicine. 2023
Abstract
OBJECTIVE To study the effectiveness and value of evidence-based nursing and predictive nursing in emergency treatment of upper gastrointestinal bleeding. METHODS A total of 100 patients with upper gastrointestinal bleeding in our hospital were selected. The period was from January 2020 to June 2022. They were grouped according to the double color ball method, 50 cases in the control group were given routine nursing, and 50 cases in the observation group were given evidence-based nursing combined with predictive nursing. The key points of evidence-based nursing are to identify the evidence-based question, search for relevant literature, identify scientifically effective nursing measures, and develop nursing care plans that are tailored to the patient's specific situation based on evidence and clinical experience. Predictive nursing requires nurses to have a high level of awareness and risk prevention consciousness to provide care for early signs of bleeding and prevent the occurrence of complications. The psychological state scores, clinical-related indicators, clinical efficacy, incidence of complications, nursing satisfaction, and quality of life scores of the two groups were compared. RESULTS After the intervention, the SAS score (42.25 ± 1.67) and SDS score (43.59 ± 1.86) of the observation group were lower than those of the control group, the bleeding times (2.41 ± 0.45) of the observation group were less than those of the control group, the hemostasis time (30.12 ± 5.38d) and hospitalization time (5.01 ± 1.11d) of the observation group were shorter than those of the control group, and the difference was statistically significant (all P < .05). The total effective rate of hemostasis (96.00%), patient satisfaction (98.00%), and scores of physical health (88.98 ± 5.59), psychological function (91.08 ± 5.11), material life state (90.54 ± 6.46) and social function (89.59 ± 5.78) in GQOLI-74 scores in the observation group were higher than those in the control group. The incidence of complications (6.00%) in the observation group was lower than that in the control group, and the difference was statistically significant (all P < .05). CONCLUSION Upper gastrointestinal bleeding is a common emergency in gastroenterology, characterized by rapid onset, severe symptoms, and quick changes. Therefore, in order to expedite the recovery of patients with acute upper gastrointestinal bleeding and ensure their safety, it is necessary to provide effective clinical emergency nursing care. Evidence-based nursing can help nurses take appropriate nursing measures based on the best and latest evidence, to meet the reasonable individualized needs of patients. Predictive nursing is a nursing model that predicts potential nursing risks in advance and takes corresponding preventive measures. It can timely and systematically address risks in nursing and promote improvements in the effectiveness of disease treatment. The combined application of evidence-based nursing and predictive nursing can improve the hemostatic efficiency of patients with upper gastrointestinal bleeding, improve the psychological state and quality of life, reduce the incidence of complications, and obtain higher satisfaction. The combined application of these two nursing models has positive implications for improving nursing efficiency, enhancing patient cooperation during emergency care, improving hemostasis effectiveness, enhancing quality of life, and fostering a harmonious nurse-patient relationship.

The Impact of a Humanized Nursing Model on the Nursing Outcomes of Emergency Transfusion Patients
Chen, J., Ding, D.
Alternative therapies in health and medicine. 2023
Abstract
BACKGROUND Emergency transfusion is a frequently performed invasive medical procedure. Patients often experience negative emotions and exhibit poor compliance during transfusion. Therefore, it is imperative to proactively implement effective nursing interventions. OBJECTIVE This study aims to investigate the impact of a humanized nursing model on the nursing outcomes of emergency transfusion patients. DESIGN This research was conducted as a randomized controlled experiment. SETTING The study was conducted in the emergency department of Suzhou Hospital of Integrated Chinese and Western Medicine. PARTICIPANTS A total of 120 patients who underwent emergency transfusion treatment in our hospital from February 2021 to October 2022 were selected. They were divided into two groups, the control group, and the observation group, using a random number table method, with 60 patients in each group. INTERVENTIONS The control group received standard nursing care, while the observation group received humanized nursing. PRIMARY OUTCOME MEASURES The primary outcome measures included (1) assessment of psychological states, (2) evaluation of physical and mental comfort, (3) assessment of transfusion compliance, (4) incidence of adverse transfusion events, and (5) assessment of nursing satisfaction. RESULTS Prior to nursing interventions, anxiety and depression scores were not significantly different between the two groups (P > .05). After nursing interventions, both groups exhibited a decrease in scores, with the observation group showing a more significant reduction compared to the control group (P < .05). In all aspects of physical and mental comfort, the observation group scored significantly higher than the control group (P < .05). Transfusion compliance and nursing satisfaction were significantly higher in the observation group compared to the control group (P < .01). The incidence of adverse transfusion events in the observation group was significantly lower than in the control group (P < .01). CONCLUSIONS Humanized nursing significantly improves anxiety and depression in emergency transfusion patients, enhances their physical and mental comfort, and increases transfusion compliance while reducing adverse transfusion events. It leads to high patient satisfaction with nursing services.

Pharmacological and non-pharmacological interventions in management of peripheral venipuncture-related pain: a randomized clinical trial
Yu, Z., Zhou, Y., Xu, X., Lin, L., Le, Q., Gu, Y.
BMC pediatrics. 2023;23(1):58
Abstract
BACKGROUND Venipuncture is a routine nursing procedure in the pediatric ward for blood collection and transfusion. However, this procedure can cause severe pain and distress if not adequately managed. METHODS Children aged 3-16 years old were randomized into three groups: EMLA group, distraction group, and combined group. The primary outcome was children's self-reported pain scored using the Wong-Baker FACES® Pain Rating Scale. The parents-reported and observer-reported pain were scored using the Revised Face, Legs, Activity, Cry and Consolability Scale, and children's salivary cortisol levels, heart rate, percutaneous oxygen saturation, venipuncture duration and retaining time of IV cannulas were the secondary outcomes. RESULTS A total of 299 children (167 male, 55.8%, median age 8.5) were enrolled: EMLA group (n = 103), distraction group(n = 96) and combined group(n = 100). There was no statistical difference in self-reported pain (P = 0.051), parent-reported pain (P = 0.072), and observer-reported pain (P = 0.906) among the three groups. All three interventions can decrease children's pain during IV cannulations. Additionally, the distraction group's salivary cortisol levels were lower than the combined group(P = 0.013). Furthermore, no significant difference was observed in the heart rate(P = 0.844), percutaneous oxygen saturation (P = 0.438), venipuncture duration (p = 0.440) and retaining time of IV cannulas (p = 0.843) among the three groups. CONCLUSIONS All three groups responded with slight pain during the peripheral venipuncture procedure. Therefore, medical workers in pediatric settings can use the interventions appropriate for their medical resources and availability while involving parents and children's preferences whenever possible.

Abstract
BACKGROUND Blood transfusion can be a lifesaving intervention after perioperative blood loss. Many prediction models have been developed to identify patients most likely to require blood transfusion during elective surgery, but it is unclear whether any are suitable for clinical practice. STUDY DESIGN AND SETTING We conducted a systematic review, searching MEDLINE, Embase, PubMed, The Cochrane Library, Transfusion Evidence Library, Scopus, and Web of Science databases for studies reporting the development or validation of a blood transfusion prediction model in elective surgery patients between 01/01/2000 to 30/06/2021. We extracted study characteristics, discrimination performance (c-statistics) of final models and data which we used to perform risk of bias assessment using the Prediction model Risk Of Bias ASsessment Tool (PROBAST). RESULTS We reviewed 66 studies (72 developed and 48 externally validated models). Pooled c-statistics of externally validated models ranged from 0.67 to 0.78. Most developed and validated models were at high risk of bias due to handling of predictors, validation methods, and too small sample sizes. CONCLUSION Most blood transfusion prediction models are at high risk of bias and suffer from poor reporting and methodological quality, which must be addressed before they can be safely used in clinical practice.

Abstract
BACKGROUND Strategies for blood conservation, coupled with a careful preoperative assessment, may be applied to Jehovah's Witnesses (JW) patients who are candidates for cardiac surgery interventions. There is a need to assess clinical outcomes and safety of bloodless surgery in JW patients undergoing cardiac surgery. METHODS We performed a systematic review and meta-analysis of studies comparing JW patients with controls undergoing cardiac surgery. The primary endpoint was short-term mortality (in-hospital or 30-day mortality). Peri-procedural myocardial infarction, re-exploration for bleeding, pre-and post-operative Hb levels and cardiopulmonary bypass (CPB) time were also analyzed. RESULTS A total of 10 studies including 2,302 patients were included. The pooled analysis showed no substantial differences in terms of short-term mortality among the two groups (OR 1.13, 95% CI 0.74-1.73, I(2)=0%). There were no differences in peri-operative outcomes among JW patients and controls (OR 0.97, 95% CI 0.39-2.41, I(2)=18% for myocardial infarction; OR 0.80, 95% CI 0.51-1.25, I(2)=0% for re-exploration for bleeding). JW patients had a higher level of pre-operative Hb (Standardized Mean Difference [SMD] 0.32, 95% CI 0.06-0.57) and a trend toward a higher level of post-operative Hb (SMD 0.44, 95% CI -0.01-0.90). A slightly lower CPB time emerged in JWs compared with controls (SMD -0.11, 95% CI -0.30-0.07). CONCLUSIONS JW patients undergoing cardiac surgery, with avoidance of blood transfusions, did not have substantially different peri-operative outcomes compared with controls, with specific reference to mortality, myocardial infarction, and re-exploration for bleeding. Our results support the safety and feasibility of bloodless cardiac surgery, applying patient blood management strategies.

Optimisation and Effect Analysis of the Blood Collection Method in Pre-Deposit Autotransfusion Patients Undergoing Thoracotomy Surgery
Jia, L., Wang, Y., Zhang, W., Lin, Y., Chen, F., Wan, Y., Fu, X.
Journal of multidisciplinary healthcare. 2023;16:2793-2798
Abstract
BACKGROUND AND PURPOSE To explore the feasibility of the modified blood collection method in pre-deposit autotransfusion in patients undergoing thoracotomy surgery. METHODS This double-blinded randomised controlled trial enrolled 92 patients from the cardiothoracic surgery department from February 2019 to October 2020. RESULTS Compared with the conventional blood collection method, the modified blood collection method avoided blood overflow from the oblique plane of the needle (χ(2) = 61.986, P < 0.01) and reduced the diameter of the bruising area after 24 hours (χ(2) = 24.611, P < 0.01). Furthermore, due to optimising the blood collection method, diastolic blood pressure reduced slightly before and after blood collection (t = 2.036, P < 0.05), and patients in the test group had less pain (based on the numerical rating score) (t = 5.556, P < 0.01). Meanwhile, the time required to collect 400 mL of blood was shortened (t = 17.744, p < 0.01). CONCLUSION An improved blood collection method can enhance the blood donation experience, avoid blood spillage, lessen pain and reduce adverse reactions. This may be of great significance in ensuring blood quality and the safety of subsequent transfusions. CLINICAL TRIALS REGISTRATION ClinicalTrials.gov Identifier: NCT05539846.

Predictive value of tachycardia for mortality in trauma-related haemorrhagic shock: a systematic review and meta-regression
Jávor, P., Hanák, L., Hegyi, P., Csonka, E., Butt, E., Horváth, T., Góg, I., Lukacs, A., Soós, A., Rumbus, Z., et al
BMJ open. 2022;12(10):e059271
Abstract
OBJECTIVES Heart rate (HR) is one of the physiological variables in the early assessment of trauma-related haemorrhagic shock, according to Advanced Trauma Life Support (ATLS). However, its efficiency as predictor of mortality is contradicted by several studies. Furthermore, the linear association between HR and the severity of shock and blood loss presented by ATLS is doubtful. This systematic review aims to update current knowledge on the role of HR in the initial haemodynamic assessment of patients who had a trauma. DESIGN This study is a systematic review and meta-regression that follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. DATA SOURCES EMBASE, MEDLINE, CENTRAL and Web of Science databases were systematically searched through on 1 September 2020. ELIGIBILITY CRITERIA Papers providing early HR and mortality data on bleeding patients who had a trauma were included. Patient cohorts were considered haemorrhagic if the inclusion criteria of the studies contained transfusion and/or positive focused assessment with sonography for trauma and/or postinjury haemodynamical instability and/or abdominal gunshot injury. Studies on burns, traumatic spinal or brain injuries were excluded. Papers published before January 2010 were not considered. DATA EXTRACTION AND SYNTHESIS Data extraction and risk of bias were assessed by two independent investigators. The association between HR and mortality of patients who had a trauma was assessed using meta-regression analysis. As subgroup analysis, meta-regression was performed on patients who received blood products. RESULTS From a total of 2017 papers, 19 studies met our eligibility criteria. Our primary meta-regression did not find a significant relation (p=0.847) between HR and mortality in patients who had a trauma with haemorrhage. Our subgroup analysis included 10 studies, and it could not reveal a linear association between HR and mortality rate. CONCLUSIONS In accordance with the literature demonstrating the multiphasic response of HR to bleeding, our study presents the lack of linear association between postinjury HR and mortality. Modifying the pattern of HR derangements in the ATLS shock classification may result in a more precise teaching tool for young clinicians.

Point-of-care platelet function testing for guided transfusion in neurosurgical management of intracranial hemorrhage: a systematic review
Xu FWX, Lim NA, Sim MA, Lean LL, Loh NW, Ng KT, Chua VTY, Chew STH, Ti LK
European journal of medical research. 2022;27(1):191
Abstract
Given the rising prevalence of antiplatelet therapy, rapid preoperative identification of patients with bleeding diathesis is necessary for the guidance of blood product administration. This is especially relevant in neurosurgery for intracranial hemorrhage (ICH), where indiscriminate transfusions may lead to further hemorrhagic or thromboembolic injury. Point-of-care (POC) testing of platelet function is a promising solution to this dilemma, as it has been proven effective in cardiac surgery. However, to date, POC platelet function testing in neurosurgery has not been extensively evaluated. This systematic review appraises the use of POC platelet function test (PFT) in emergency neurosurgery in terms of its impact on patient outcomes.A comprehensive search was conducted on four electronic databases (Pubmed, MEDLINE, Embase, and Cochrane) for relevant English language articles from their respective inceptions until 1 June 2022. We included all randomized controlled trials and cohort studies that met the following inclusion criteria: (i) involved adult patients undergoing neurosurgery for ICH; (ii) evaluated platelet function via POC PFT; (iii) reported a change in perioperative blood loss; and/or (iv) reported data on treatment-related adverse events and mortality. Assessment of study quality was conducted using the Newcastle Ottawa Quality Assessment Scale for Cohort Studies and Case-Control Studies, and the JBI Critical Appraisal Checklist for Case Series.The search yielded 2,835 studies, of which seven observational studies comprising 849 patients met the inclusion criteria for this review. Overall, there is evidence that the use of POC PFT to assess bleeding risk reduced bleeding events, thromboembolic adverse outcomes, and the length of hospitalization. However, there is currently insufficient evidence to suggest that using POC PFT improves blood product use, functional outcomes or mortality.

Nayeri ND, Nadali J, Divani A, Hatefimoadab N
Florence Nightingale journal of nursing. 2022;30(3):288-300
Abstract
AIM: Blood product administration is a vital and possibly life-threatening issue that may increase the risk of clinical damage in patients. This review aims to provide a comprehensive review of the ways to improve blood transfusion safety. METHOD In order to conduct this systematic review, electronic databases, including PubMed/MEDLINE, EMBASE, Web of Science, Cochrane CENTRAL, Scopus, and Google Scholar, were searched for data of the last 30 years using keywords including patient safety, blood transfusion, risk management, safety management, and transfusion reaction. The inclusion criteria set for the selection of quantitative articles were articles written in English and published in peer-reviewed journals during the mentioned period. In this study the publications are reviewed in line with the PRISMA guide checklist. RESULTS Among 6105 articles found during the initial search, 16 articles were finalized for further investigation. Fifty percent of the included articles discussed the use of modern technology including patient identification system, barcode technology, portable computer systems, and databases. Moreover, 31% of the studies evaluated the use of alternative methods for transfusion of blood products including mediastinal blood transfusion, the use of autologous blood in adult patients, the use of cord blood in children, the use of hemoglobin-based oxygen carrier-201, and the injection of fresh whole blood. About 18% of articles drew attention to indications and thresholds as an essential factor increasing patient safety. CONCLUSION It was concluded from this study that the use of technology leads to fewer human errors and complications caused by these errors. In addition, some alternative methods can be used in a cost-effective way to reduce serious adverse events caused by common strategies.
