Clinical application of a modified predeposit autologous red blood cell apheresis in multistage spinal fusion: a single-center retrospective study. Front Med (Lausanne) 2023; 10:1149093. [PMID: 37256088 PMCID: PMC10225601 DOI: 10.3389/fmed.2023.1149093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 04/12/2023] [Indexed: 06/01/2023] Open
Abstract
Purpose This study aimed to evaluate the efficacy and safety of predeposit autologous RBC apheresis (PARA) in patients undergoing multilevel spinal fusion surgery. Methods A total of 112 patients from January 2020 to June 2022 were divided into two groups according to PARA: the PARA group (n = 51) and the control group (n = 61). The baseline characteristics of the patients, outcomes, transfusion cost, hospitalization cost, length of stay, complications, and changes in hemoglobin and hematocrit levels between the two groups were compared. Results The baseline characteristics were similar in both groups. No significant differences were found in functional outcomes, including VAS score (p = 0.159), ODI score (p = 0.214), JOA score (p = 0.752), and SF-36 score (p = 0.188) between the PARA and control groups. The amount and rate of intraoperative and perioperative allogeneic RBC transfusion were significantly higher in the control group than in the PARA group (p < 0.001). The postoperative (9.04 ± 3.21 vs. 11.05 ± 3.84, p = 0.004) and total length of stay (15.78 ± 3.79 vs. 17.36 ± 4.08, p = 0.038) in the PARA group were significantly lower than those in the control group, respectively. Despite no difference in hospitalization cost (p = 0.737), the total blood transfusion cost in the PARA group was significantly lower, compared with the control group (p < 0.001). For safety evaluation, there were no significant differences in Hb and Hct levels between the two groups at admission, on postoperative day 1, and postoperative day 3, respectively (p > 0.05). Moreover, the number of postoperative infections in the PARA group was significantly lower than that in the control group (p = 0.038). Conclusion PARA was a novel, safe, and highly efficient technique for mass autologous blood preparation in a quite short preparation time. This method could significantly reduce the amount of allogeneic blood transfusion and length of stay, which could provide a theoretical basis for following clinical practice about the technique.

Abstract
Patient blood management (PBM) strategies aim to maintain hemoglobin concentration, optimize hemostasis, and minimize blood loss to improve patient outcomes. Because postpartum hemorrhage (PPH) is a leading cause of maternal mortality and blood product utilization, PBM principles can be applied in its therapeutic approach. First, pre-operative identification of risk factors for PPH and identification of peri-delivery anemia should be conducted. Iron supplementation should be used to optimize hemoglobin concentration before delivery; it can also be used to treat anemia in the postpartum period after severe PPH. Both acute normovolemic hemodilution and intraoperative cell salvage can be effective techniques to reduce allogeneic blood transfusion during or after surgical procedures. Furthermore, these strategies appear to be safe when used in the pregnant population.

Abstract
BACKGROUND To develop an easy-to-use model to predict the probability of perioperative blood transfusion (PBT) in patients undergoing liver resection for hepatocellular carcinoma (HCC). METHOD 878 patients from Eastern Hepatobiliary Surgery Hospital of Shanghai were enrolled in the training cohort, while 691 patients from Tongji Hospital of Wuhan and 364 patients from two hospitals from Europe and America served as the Eastern and Western external validation cohorts, respectively. Independent predictors of PBT were identified and used for the nomogram construction. The predictive performance of the model was assessed using the concordance index (C-index) and calibration plot, and externally validated using the two independent cohorts. This model was compared with four currently available prediction risk scores. RESULTS Eight preoperative variables were identified as independent predictors of PBT, which were incorporated into the new nomogram model, with a C-index of 0.833 and a well-fitted calibration plot. The nomogram performed well on the externally Eastern and Western validation cohorts (C-indexes: 0.786 and 0.777). The discriminatory ability of the nomogram was superior to the four currently available prediction scores (C-indexes: 0.833 vs. 0.671-0.770). The nomogram was programmed into an online calculator, which is available at http://www.asapcalculate.top/Cal3_en.html. CONCLUSION A nomogram model, using an easy-to-access website, can be used to calculate the PBT risk and identify which patients undergoing HCC resection are at high risks of PBT and can benefit most by using blood conservation techniques.

Abstract
PURPOSE OF REVIEW To provide a comprehensive overview of the predisposing factors that contribute to a risk of excess bleeding for surgical therapy in the head and neck regions, provide a thorough overview of techniques and tools for managing blood loss complications, and provide intervention algorithms to help guide clinical decision making. RECENT FINDINGS With the current landscape of medications and reversal agents, protocols for intervention in a variety of situations, and new tools for blood loss management all rapidly changing and being developed it is critical to stay up to date to provide patients the best care in the most critical of situations. SUMMARY With the risk of blood loss complications in head and neck surgery ranging from minimal to extreme surgeons require a comprehensive understanding risk factors, patient evaluation tools, and proper management algorithms. The first opportunity to prevent unnecessary blood loss and blood loss complications is the health history and physical appointment where a clinician can identify any medications, conditions, or other predisposing factors that would elevate a patient's risk of excess bleeding and the necessity for treatment augmentation. Although not all complications can be prevented because of the natural physiological variation that occurs from patient to patient, despite proper and proper diagnostics, a full working knowledge of most likely complications, hemostatic tools, and concise communication with team members can prevent a lot of blood loss and the complications associated.

Abstract
Steady blood pressure within normal limits during surgery is one of the markers of the ideal and skillful anesthesia. Yet, reduced blood pressure is advantageous in some settings because it can contribute to a reduction in overall blood loss and improve the surgical field conditions. Controlled hypotension during anesthesia or hypotensive anesthesia is often used in major maxillofacial operations. Since hypotensive anesthesia carries the risk of hypoperfusion to important organs and tissues, mainly the brain, heart, and kidneys, it cannot be applied safely in all patients. In this paper we review the medical literature regarding hypotensive anesthesia during major maxillofacial surgery, the means to achieve it, and the risks and benefits of this technique, in comparison to normotensive anesthesia.

Abstract
BACKGROUND There is accumulating evidence that restricting blood transfusions improves outcomes, with newer trials showing greater benefit from more restrictive strategies. We systematically evaluated the impact of various transfusion triggers on clinical outcomes. METHODS The MEDLINE database was searched from 1966 to April 2013 to find randomized trials evaluating a restrictive hemoglobin transfusion trigger of <7 g/dL, compared with a more liberal trigger. Two investigators independently extracted data from the trials. Outcomes evaluated included mortality, acute coronary syndrome, pulmonary edema, infections, rebleeding, number of patients transfused, and units of blood transfused per patient. Extracted data also included information on study setting, design, participant characteristics, and risk for bias of the included trials. A secondary analysis evaluated trials using less restrictive transfusion triggers, and a systematic review of observational studies evaluated more restrictive triggers. RESULTS In the primary analysis, pooled results from 3 trials with 2364 participants showed that a restrictive hemoglobin transfusion trigger of <7 g/dL resulted in reduced in-hospital mortality (risk ratio [RR], 0.74; confidence interval [CI], 0.60-0.92), total mortality (RR, 0.80; CI, 0.65-0.98), rebleeding (RR, 0.64; CI, 0.45-0.90), acute coronary syndrome (RR, 0.44; CI, 0.22-0.89), pulmonary edema (RR, 0.48; CI, 0.33-0.72), and bacterial infections (RR, 0.86; CI, 0.73-1.00), compared with a more liberal strategy. The number needed to treat with a restrictive strategy to prevent 1 death was 33. Pooled data from randomized trials with less restrictive transfusion strategies showed no significant effect on outcomes. CONCLUSIONS In patients with critical illness or bleed, restricting blood transfusions by using a hemoglobin trigger of <7 g/dL significantly reduces cardiac events, rebleeding, bacterial infections, and total mortality. A less restrictive transfusion strategy was not effective.

Abstract
Anemia and red blood cell (RBC) transfusions are common in critically ill and injured, trauma, and surgical patients. Tolerance of anemia is highly variable, depending on the presence of cardiovascular and other comorbid diseases that may diminish the hemodynamic response to a lower hemoglobin (Hb) level. The quest to define a minimum threshold Hb concentration at which patients achieve significant benefit to improve outcome has not yet been identified. Complications related to RBC transfusion are related to RBC storage and intrinsic properties of donor allogeneic RBCs, including bacterial contamination, transfusion-related acute lung injury, and transfusion-related immunomodulation. The best evidence related to transfusion-related outcome involves titrating transfusion requirements to parameters of severity of illness rather than arbitrarily defined Hb levels.

Abstract
An evolving understanding of the consequences of allogeneic blood transfusion and escalating costs of providing allogeneic blood have resulted in an interest in blood management. Understanding the consequences of allogeneic transfusion includes a recognition of the immunosuppressive effects of allogeneic transfusion, a growing awareness of transfusion-related acute lung injury, and a rediscovery of transfusion-associated circulatory overload. More recently, interest has focused on the effect of stored blood on patient outcome. Although this discussion is not all-inclusive, it is intended to show that many techniques can be applied to decrease the exposure to allogeneic blood.

Abstract
Acute normovolemic hemodilution (ANH) can be used in acute lung injury (ALI) patients who refuse blood transfusions. To investigate the effects of hemodilution on the acute inflammatory response in lung injury, the authors studied the effects of ANH in a rat model of bleomycin-induced lung injury. Bleomycin (10 mg/kg) was used to induce lung injury in 2 groups of rats. The treatment groups included a lung injury group with hemodilution (HI), a lung injury group without hemodilution (NHI), and a control group. Hemodilution was performed by removing blood and substituting the same amount of hydroxyethyl starch solution targeted to 7.0 g/dL via the right and left internal jugular veins. At day 3 after bleomycin instillation, systemic hemoglobin concentration was 9.5 +/- 1.1 g/dL. Tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6 levels measured in the bronchoalveolar lavage fluid (BALF), blood, and lung tissue were not significantly different between the HI and NHI groups 3 days after lung injury. Microscopic findings showed fibrosis and inflammation in the HI and NHI groups 28 days after lung injury, but no significant differences were found between the 2 groups. Hemodilution after bleomycin administration did not further affect the acute inflammatory response or lung injury.

Abstract
This review examines the science and methodology of blood conservation in modern anaesthetic and surgical practice. Blood transfusion is associated with increased morbidity and mortality in all surgical patients, and the reduction or even elimination of transfusion has been and continues to be the subject of much research. Blood substitutes, despite extensive investigation, have not been proved successful in trials to date, and none have entered clinical practice. Pharmacological treatments include antifibrinolytic drugs (although aprotinin is no longer in clinical use), recombinant factor VIIa, desmopressin, erythropoietin and topical haemostatic agents, and the role of each of these is discussed. Autologous blood transfusion has recently fallen in popularity; however, cell salvage is almost ubiquitous in its use throughout Europe. Anaesthetic and surgical techniques may also be refined to improve blood conservation. Blood transfusion guidelines and protocols are strongly recommended, and repetitive audit and education are instrumental in reducing blood transfusion.

Abstract
Postpartum hemorrhage (PPH) is an obstetric emergency that can occur following vaginal or cesarean delivery. Rapid diagnosis of PPH using laboratory and clinical parameters is an important first step in its management. Traditional blood components, including packed red blood cells, platelets, plasma, and cryoprecipitate, should be used in patients with significant bleeding. Recent studies underline the utility of transfusing these components in defined ratios to prevent dilutional coagulopathy. Disseminated intravascular coagulation (DIC) should be considered in severely bleeding obstetric patients and should be treated aggressively using blood components. Newer hemostatic agents, such as activated factor VII, will play significant roles in patients with bleeding that is refractory to standard therapy. Implementation of an obstetric bleeding protocol that integrates new knowledge in coagulation should aid physicians in improving outcomes for the mother and her fetus.
