Abstract
OBJECTIVE To explore the clinical effect of predeposit, salvage, and hemodilution autotransfusion on patients with femoral shaft fracture (FSF) surgery. METHODS Selected patients with FSF were randomly divided into three groups: intraoperative blood salvage autotransfusion, preoperative hemodilution autohemotransfusion, and predeposit autotransfusion. Five days after the operation, the body temperature, heart rate, blood platelet (PLT), and hemoglobin (Hb) of patients were determined. The concentrations of EPO and GM-CSF in the three groups were calculated by ELISA. The content of CD14+ monocytes was calculated by FCM assay. The growth time and condition of the patient's callus were determined at the 30th, 45th, and 60th day after operation. Cox regression analysis was used to analyze the correlation between EPO, GM-CSF, CD14+ mononuclear content, callus growth, and autotransfusion methods. RESULTS There were no statistically significant differences in body temperature and heart rate between the three groups (p > 0.05). PLT and Hb in the Predeposit group were markedly increased compared with that in the Salvage and Hemodilution groups. The concentrations of EPO and GM-CSF in the Predeposit group were markedly increased compared with that in the Salvage and Hemodilution groups. The content of CD14+ monocytes in the Predeposit group was significantly higher than that in the Salvage and Hemodilution groups. Predeposit autotransfusion promotes callus growth more quickly. CONCLUSION Predeposit autotransfusion promoted the recovery of patients with FSF after the operation more quickly than salvage autotransfusion and hemodilution autotransfusion.

Abstract
INTRODUCTION Colorectal cancer liver metastasis (CRLM) occurs in upto 50% of cases and drives patient outcomes. Up-front liver resection is the treatment of choice in resectable cases. There is no consensus yet established as to the safety of intraoperative autotransfusion in liver resection for CRLM. METHODS Patients undergoing curative-intent hepatectomy for CRLM at a single quaternary-care institution from 1999 to 2016 were included. Demographics, surgical variables, Fong Clinical Risk Score (FCRS), use of intraoperative auto and/or allotransfusion, and survival data were analyzed. Propensity score matching (PSM) was performed accounting for allotransfusion, extent of hepatectomy, FCRS, and systemic treatment regimens. RESULTS Three-hundred sixteen patients were included. The median follow-up was 10.4 years (7.8-14.1 years). The median recurrence-free survival (RFS) and overall survival (OS) in all patients were 1.6 years (interquartile range: 0.63-6.6 years) and 4.4 years (2.1-8.7), respectively. Before PSM, there was a significantly reduced RFS in the autotransfusion group (0.96 vs. 1.73 years, p = 0.20). There was no difference in OS (4.11 vs. 4.44 years, p = 0.118). Patients in groups of FCRS 0-2 and 3-5 both had reduced RFS when autotransfusion was used (p = 0.005). This reduction in RFS was further found when comparing autotransfusion versus no autotransfusion within the FCRS 0-2 group and within the FCRS 3-5 group (p = 0.027). On Cox-regression analysis, autotransfusion (hazard ratio = 1.423, 1.028-2.182, p = 0.015) remained predictive of RFS. After PSM, there were no differences in FCRS (p = 0.601), preoperative hemoglobin (p = 0.880), allotransfusion (p = 0.130), adjuvant chemotherapy (p = 1.000), immunotherapy (p = 0.172), tumor grade (p = 1.000), use of platinum-based chemotherapy (p = 0.548), or type of hepatic resection (p = 0.967). After matching, there was a higher rate of recurrence with autotransfusion (69.0% vs. 47.6%, p = 0.046). There was also a reduced time to recurrence in the autotransfusion group compared with the group without (p = 0.006). There was no difference in OS after PSM (p = 0.262). CONCLUSION Autotransfusion may adversely affect recurrence in liver resection for CRLM. Until further studies clarify this risk profile, the use of intraoperative autotransfusion should be critically assessed on a case-by-case basis only when other resuscitation options are not available.

Abstract
A 2-year-old spayed female Siberian Husky was presented with a history of acute onset lethargy, collapse, haematochezia and vomiting. The patient was severely tachycardic and hypotensive. Point-of-care ultrasound revealed gallbladder wall thickening and peritoneal effusion consistent with haemorrhage on subsequent abdominocentesis. Despite attempted medical stabilization over the course of several hours, including blood products and multiple autotransfusions, the patient progressed to cardiopulmonary arrest. The dog was successfully resuscitated but was subsequently euthanized. Necropsy revealed a severe, acute hemoperitoneum secondary to rupture of the left lateral liver lobe. A tear in the hepatic capsule was identified along with a large hematoma. A single adult nematode, consistent with Dirofilaria immitis, was found in a pulmonary vessel in the right caudal lung lobe. The remaining necropsy findings were supportive of the clinical diagnosis of anaphylaxis. This report details a case, with necropsy findings, supporting a diagnosis of anaphylaxis and severe, refractory hemoperitoneum resulting from hepatic rupture. Acute hepatic rupture should be considered in cases of anaphylaxis-related hemoperitoneum.

Abstract
BACKGROUND Autotransfusion following vaginal delivery has not been as widely adopted and existing data on this topic are limited to small case series. METHODS This is a single-center retrospective matched cohort study. Deliveries exposed to autotransfusion during obstetric hemorrhage were matched to unexposed controls with obstetric hemorrhage who did not receive autotransfusion. The primary outcome was allogeneic transfusion of packed red blood cells. Planned secondary analyses included change in hemoglobin following delivery, composite maternal safety outcomes, and unplanned postpartum health care utilization. RESULTS Thirty-six deliveries exposed to autotransfusion were matched to 144 unexposed controls. There was no significant difference in allogenic transfusion of packed red blood cells in the patients exposed to autotransfusion red with unexposed controls (adjusted OR 1.1; 95% CI 0.5-2.4). Deliveries that received autotransfusion had a less severe pre- to post-delivery decline in hemoglobin compared with unexposed controls across all values of QBL (p = .003). There were no significant differences in maternal morbidity outcomes evaluated in exposed versus unexposed deliveries. CONCLUSION Autotransfusion in cases of vaginal obstetric hemorrhage did not attenuate rates of allogenic packed red blood cell transfusion but did result in a less severe pre- to postdelivery decline in hemoglobin at discharge. Autotransfusion cases did not have any markers of increased maternal morbidity when compared with a control group. These findings support emerging evidence indicating that autotransfusion of blood lost during vaginal obstetric hemorrhage is a safe and potentially effective tool for use in the management of obstetric hemorrhage.

Abstract
OBJECTIVE This study was performed to evaluate the effect of a homemade autotransfusion pressure-control system on the regulation of negative pressure and to clarify the influence of different negative pressures on the recovered erythrocytes. METHODS Fifty patients were randomly divided into five groups, and five different suction-generated negative pressures were applied. Before suction, 6 mL of blood was collected from the surgical field; after suction, 6 mL of blood was collected from the blood storage tank. The hemoglobin, hematocrit, mean corpuscular volume, newly generated standardized plasma free hemoglobin, and change in the hemolysis rate of erythrocytes before and after suction were compared. Additionally, the erythrocyte morphology was observed. RESULTS The hemoglobin and hematocrit were significantly different before and after suction in all five groups. As the suction pressure increased, gradual increases were noted in the number of abnormal erythrocytes in the field of view, the newly generated standardized plasma free hemoglobin, and the change in the hemolysis rate. CONCLUSIONS The destruction rate of erythrocytes increased as the suction-generated negative pressure increased. When using a pressure-control system, a negative pressure of <200 mmHg should be applied to reduce the damage to the autotransfused blood.

Abstract
BACKGROUND We used sodium citrate as an alternative anticoagulation agent to heparin in the procedure of autologous blood transfusion with patients with postoperative haemorrhage after CPB. The aim of study was to evaluate the efficacy and safety of sodium citrate used in shed mediastinal blood autotransfusion after cardiac surgery. METHODS Ninety-three patients were divided into two groups in this study. In the control group, 52 patients' shed mediastinal blood was discarded. The reinfusion group consisted of 41 patients receiving a reinfusion of washed autologous red cells from shed mediastinal blood. Each 400 mL shed blood sample was anticoagulated by 140 mL of 1.6% diluted sodium citrate in the washing procedure using a blood recovery machine. Hemoglobin (Hb), hematocrit (Hct), and electrolyte concentrations in both the patients and shed mediastinal blood were measured before and after this procedure. RESULTS The mean volume of autotransfused shed blood was 239.5 ± 54.6 mL.The Hct of the washed red cells was 56.8 ± 6.1%. Significantly, fewer units of allogeneic blood were required per patient in the reinfusion group at 24 h postoperatively (2.91 ± 1.34 vs 4.03 ± 0.19 U, p = 0.002). At 24 h postoperatively, Hb and Hct levels were higher in the reinfusion group than in the control group. The calcium ion concentration was very low in the shed mediastinal blood, 0.25 ± 0.08 mmol/L, and was lower after washing, 0.15 ± 0.04 mmol/L. CONCLUSIONS Sodium citrate, as an alternative anticoagulant agent, can be used in autologous shed mediastinal blood transfusion after CPB cardiac surgery. This procedure can effectively reduce the amount of allogeneic blood for patients with haemorrhage.

Abstract
A 64-year-old male patient was admitted to the catheterization laboratory with a suspected myocardial infarction and in cardiogenic shock. Upon further investigation, a massive bilateral pulmonary embolism with signs of right heart dysfunction was discovered, leading to a decision to perform a direct interventional treatment with a thrombectomy device for thrombus aspiration. The procedure was successful in removing almost the entirety of the thrombotic material from the pulmonary arteries. The patient's hemodynamics stabilized and oxygenation improved instantly. The procedure required a total of 18 aspiration cycles. Each aspiration contained approx. 60 mL blood amounting to a total of approx. 1080 mL of blood. During the procedure, a mechanical blood salvage system was used to resupply 50% of the blood via autotransfusion that would otherwise have been lost. The patient was transferred to the intensive care unit for post-interventional care and monitoring. A CT angiography of the pulmonary arteries after the procedure confirmed the presence of only minor residual thrombotic material. The patient's clinical, ECG, echocardiographic, and laboratory parameters returned to normal or near normal ranges. The patient was discharged shortly after in stable conditions on oral anticoagulation.

Abstract
OBJECTIVE To evaluate the effect of intraoperative blood cell salvage and autotransfusion (IBSA) use on red blood cell (RBC) transfusion and postoperative outcomes in liver surgery. BACKGROUND Intraoperative RBC transfusions are common in liver surgery and associated with increased morbidity. IBSA can be utilized to minimize allogeneic transfusion. A theoretical risk of cancer dissemination has limited IBSA adoption in oncologic surgery. METHODS Electronic databases were searched from inception until May 2021. All studies comparing IBSA use with control in liver surgery were included. Screening, data extraction, and risk of bias assessment were conducted independently, in duplicate. The primary outcome was intraoperative allogeneic RBC transfusion (proportion of patients and volume of blood transfused). Core secondary outcomes included: overall survival and disease-free survival, transfusion-related complications, length of hospital stay, and hospitalization costs. Data from transplant and resection studies were analyzed separately. Random effects models were used for meta-analysis. RESULTS Twenty-one observational studies were included (16 transplant, 5 resection, n=3433 patients). Seventeen studies incorporated oncologic indications. In transplant, IBSA was associated with decreased allogeneic RBC transfusion [mean difference -1.81, 95% confidence interval (-3.22, -0.40), P =0.01, I 2 =86%, very-low certainty]. Few resection studies reported on transfusion for meta-analysis. No significant difference existed in overall survival or disease-free survival in liver transplant [hazard ratio (HR)=1.12 (0.75, 1.68), P =0.59, I 2 =0%; HR=0.93 (0.57, 1.48), P =0.75, I 2 =0%] and liver resection [HR=0.69 (0.45, 1.05), P =0.08, I 2 =0%; HR=0.93 (0.59, 1.45), P =0.74, I 2 =0%]. CONCLUSION IBSA may reduce intraoperative allogeneic RBC transfusion without compromising oncologic outcomes. The current evidence base is limited in size and quality, and high-quality randomized controlled trials are needed.

Abstract
Senile glaucoma is a common ophthalmological disease in the elderly. It is a disease of visual papillary perfusion caused by elevated intraocular pressure, complicated by visual dysfunction. Glaucoma can cause serious damage to the normal vision of the elderly. Therefore, exploring the related molecular mechanisms of glaucoma is of great significance to the diagnosis and treatment of glaucoma. This is an exploratory study. Establish a mouse model and conduct experimental groupings. After one week of adaptive feeding, the mice were intraperitoneally injected with an anesthetic mixture: ketamine + xylazine. Then the mice were sacrificed by neck dissection, and the eyeball tissues were immediately dissected. HE staining was used to analyze the histopathological characteristics of the retina of each group of mice. MitoSOX fluorescent probe was used to analyze the content of ROS in retinal tissue. The ELISA analysis was used to detect the activation of β-galactosidase for the aging characteristics of retinal ganglion cells in retinal tissues. Immunohistochemistry experiments were used to analyze the expression of telomerase TERT in retinal tissues. Western blot analysis was used to determine the expression of proteins POT1, TERF1, TERF2, and TINF2 in retinal tissues. The HE staining experiment showed that the damage of retinal tissue decreased from group Glaucoma to group Old, group Old to group Young. The experimental results of MitoSOX fluorescent probe show that ROS content is positively correlated with the degree of tissue damage. ELISA analysis results showed that the expression trend of β-galactosidase was the same as the ROS content. The protein expression levels related to telomere protection (TRET, POT1, TREF1, TREF2 and TINF2) all increased from group Glaucoma to group Old, group Old to group Young. The increase in ROS content, the decrease in telomere protection-related protein expression (telomere shortening) induced by ROS, and the increase of the expression of β-galactosidase, are all potential molecular mechanisms for the occurrence of angle-closure glaucoma in elderly patients.

Abstract
INTRODUCTION Globally, haemorrhage is the leading cause of both maternal mortality and preventable trauma death. For patients suffering from haemorrhage, prompt blood transfusion can be life-saving; however, safe and sufficient blood is often lacking in low-resource settings (LRS). Autotransfusion (AT), in which the patient's own blood is collected and transfused back, is an established alternative to donor blood transfusions, although one that is primarily performed with advanced AT systems. Research on basic AT in LRS is scarce. Therefore, we aimed to consolidate all available information on the current use of basic AT in LRS and to identify AT techniques and devices described for use in such settings. DESIGN Scoping review. METHODS We systematically searched four key databases: PubMed, Web of Science, Global Health and Cochrane Library as well as several grey literature databases and databases of relevant organisations. The final search was conducted on 22 April 2019. We included all types of studies referring to any information on basic AT used or sought to be used in LRS, published in English and dated after 31 December 2008. We synthesised the data from the included studies, results were charted or summarised narratively. RESULTS Some 370 records were reviewed, yielding 38 included documents. We found a paucity of scientific evidence as well as contradictory information on the extent of AT use and that AT use is largely undocumented. The most commonly described indications were haemoperitoneum (primarily among obstetric patients) and haemothorax. We identified three AT techniques used in LRS. Additionally, two new devices and one filter are described for potential use in LRS. CONCLUSIONS Basic AT is practiced for certain obstetric and trauma indications. However, context-specific studies are needed to determine the technique's safety and effectiveness. Extent of use is difficult to assess, but our results indicate that basic AT is not a widely established practice in LRS. Future research should address the bottlenecks hampering basic AT availability. New AT devices for use in LRS are described, but their utility and cost-effectiveness remain to be assessed.

Abstract
OBJECTIVE To report maternal outcomes in a cohort of women who received autotransfusion of vaginally shed blood and to describe the feasibility of blood collection and cell salvage processing at the time of vaginal hemorrhage. STUDY DESIGN AND METHODS We conducted a retrospective case series of patients who received autotransfusion of vaginally shed blood at the time of obstetric hemorrhage from January 2014 to August 2020. Maternal data and cell salvage utilization characteristics were abstracted from the electronic medical record. RESULTS Sixty-four cases were identified in which autotransfusion of vaginally shed blood occurred during an obstetric hemorrhage. Median quantitative blood loss was 2175 ml (interquartile range 1500-2250 ml) with 89% of cases having a blood loss greater than 1000 ml. Patients on average received approximately 1.3 units of autologous blood product (384 ml, interquartile range 244-520 ml) and no direct adverse events were observed during transfusion. We observed heterogeneity in autologous blood volume across all values of quantitative blood loss. The need for allogenic blood transfusion was common and occurred in 72% of all cases (N = 46). There were no documented cases of maternal sepsis or severe infectious morbidity. CONCLUSION In 64 cases where autotransfusion of vaginally shed blood occurred, autotransfusion was well tolerated. Heterogeneity in autologous blood volume collection likely represents the lack of standardized protocols for blood collection in the delivery room. Autotransfusion of vaginally shed blood is a feasible and reasonable technique to employ during severe obstetric hemorrhage.

Abstract
Autotransfusion refers to a blood transfusion method in which the blood or blood components of the patient are collected under certain conditions, returned to himself when the patient needs surgery or emergency after a series of storing and processing. Although autotransfusion can avoid blood-borne diseases and adverse reactions related to allogeneic blood transfusion, a series of structural and functional changes of erythrocytes will occur during extension of storage time, thus affecting the efficacy of clinical blood transfusion. Our research was aimed to explore the change of erythrocyte oxygen-carrying capacity in different storage time, such as effective oxygen uptake (Q), P50, 2,3-DPG, Na+-K+-ATPase, to detect membrane potential, the change of Ca2+, and reactive oxygen species (ROS) change of erythrocytes. At the same time, Western blot was used to detect the expression of Mitofusin 1 (Mfn1) and Mitofusin 2 (Mfn2) proteins on the cytomembrane, from the perspective of oxidative stress to explore the function change of erythrocytes after different storage time. This study is expected to provide experimental data for further clarifying the functional status of erythrocytes with different preservation time in patients with autotransfusion, achieving accurate infusion of erythrocytes and improving the therapeutic effect of autologous blood transfusion, which has important clinical application value.

Abstract
AIM Intraoperative cell salvage and autotransfusion (ICSA) is a useful technique for women undergoing cesarean sections who are predicted to experience significant bleeding. This method can reduce allogeneic transfusions as well as its associated risks and costs. Amniotic fluid embolism (AFE) is an abnormal maternal response to ICSA similar to the classic systemic inflammatory response syndrome, but its mechanism is not well understood. This study was conducted to investigate the biochemical aspects of AFE. METHODS A prospective case-controlled pilot study was conducted in a general perinatal hospital in Japan. ICSA was performed using a two-step retransfusion process. Blood samples were collected presurgery, immediately postsurgery, and 24 h after surgery. Changes in sialyl Tn antigen (STN), complement C3 and C4, fibrinogen, and fibrin degradation product and D-dimer, C1 esterase inhibitor, and interleukin-8 (all considered AFE-related markers) activities were compared between patients who underwent cesarean sections with ICSA (ICSA group) versus without ICSA (control group). RESULTS Fibrinogen levels were significantly lower in the ICSA group than in the control group before surgery but not immediately after or 24 h after surgery. D-dimer was significantly higher immediately after surgery but not 24 h later. STN was significantly lower only before surgery. None of the AFE-related markers showed significant differences between the groups after 24 h. No adverse events were observed in the ICSA group. CONCLUSIONS There is no clinical evidence that ICSA alters the biochemical statuses of AFE-related markers in a manner that could lead to adverse maternal responses.

Abstract
BACKGROUND Pre-operative autologous blood donation (PABD) is one of the most widely distributed autologous blood donation means, which has positive effect on erythropoiesis. However, whether PABD can stimulate the bone marrow hematopoiesis after hepatectomy have not been reported. METHODS Totally 80 New Zealand rabbits were randomly divided into 4 groups that included control group, surgery group, hemodilutional autotransfusion (HA) group and PABD group. Automatic reticulocyte examination was performed to detect the content of reticulocyte and immature reticulocyte fractions (IRF). Flow cytometric analysis was employed to monitor the level of CD34+ cells and the cell cycle status. Southern blotting was conducted to determine the telomere length of CD34+ cells. RESULTS The content of high fluorescence reticulocytes (HFR) and IRF was decreased at 6 h and 24 h after autotransfusion. However, the level of CD34+ cells was upregulated after PABD. Cell cycle status analysis revealed that majority of the CD34+ cells in HA and PABD group were maintained in G0/G1 phase. The telomere length in HA and PABD group was shorten than that of control group and surgery group. CONCLUSION PABD could promote the bone marrow hematopoietic functions in rabbits after hepatectomy via stimulating proliferation of CD34+ cells and shortening the telomere length of CD34+ cells, but the content of HFR was not increased immediately because of the stuck of CD34+ cells in G0/G1 phase.

Abstract
Background: Intraoperative predonated autologous blood transfusion is thought to replenish platelets and coagulation factors and ameliorate coagulopathy. This study aimed to evaluate whether intraoperative predonated autotransfusion improves coagulopathy during thoracic aortic surgery. Methods: Patients who underwent thoracic aortic surgery were randomized into two groups as follows: those who received intraoperative predonated blood (group A: n = 31) and those who did not receive (group N: n = 22). In group A, autologous blood was retransfused immediately after cessation of cardiopulmonary bypass (c-CPB). Results: The mean intraoperative allogenic blood or blood product transfusion requirements were significantly lesser in group A than in group N (packed red blood cells [RBCs]: 6.3 ± 5.1 vs. 9.1 ± 4.3 units, p = 0.04; fresh frozen plasma [FFP]: 3.0 ± 4.1 vs. 6.1 ± 5.7 units, p = 0.03). After c-CPB, hemoglobin (Hb) level, platelet count, and coagulopathy became significantly worse than those at the start of surgery in both the groups. However, the values significantly improved 30 min after c-CPB only in group A. Renal function was significantly worse in group N. Conclusions: Intraoperative predonated autotransfusion significantly improved coagulopathy, with reduced allogeneic blood transfusion volume during thoracic aortic surgery. Furthermore, reduction of allogeneic blood transfusion may reduce the adverse effects on renal function.

Abstract
Autologous blood cell salvage reduces the need for postoperative allogeneic blood transfusion and alleviates immunologic reactions, so the technique is commonly used in cardiac surgery. The continuous autotransfusion system is a type of blood cell salvage device. Although the processing program of continuous autotransfusion system includes filtering of several materials from suctioned blood, such as clots, leukocytes, cytokines, and complement, we identified some unexpected blood clots in the reinfusion bag. Pathologic examination revealed that the clots were composed of fibrin, red blood cell aggregates, and histiocytes. We report two cases of these abnormal findings during the use of CATSmart in cardiac surgery.

Abstract
OBJECTIVE To evaluate systematically the safety and efficacy of intra-operative cell salvage (ICS) in urology. METHODS A search of Medline, Embase and Cochrane Library to August 2017 was performed using methods pre-published on PROSPERO. Reporting followed the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Eligible titles were comparative studies published in English that used ICS in urology. Primary outcomes were allogeneic transfusion rates (ATRs) and tumour recurrence. Secondary outcomes were complications and cost. RESULTS Fourteen observational studies were identified, with a total of 4 536 patients. ICS was compared with no the blood conservation technique (seven studies), preoperative autologous donation (PAD; five studies) or both (two studies). Cohorts underwent open prostatectomy (11 studies), open cystectomy (two studies) or open partial nephrectomy (one study). Meta-analysis was possible only for ATRs within prostatectomy studies. In this setting, ICS reduced ATR compared with no the blood conservation technique (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.15-0.76) but not PAD (OR 0.76, 95% CI 0.39-1.31). In the non-prostatectomy setting, ATRs amongst patients who underwent ICS were significantly higher or similar in one and two studies, respectively. Tumour recurrence was found to be significantly less common (two studies), similar (eight studies) or not measured (four studies). All six studies reporting complications found no difference in their ICS cohorts. Regarding cost, one study from 1995 found ICS more expensive than PAD, while two more recent studies found ICS to be cheaper than no blood conservation technique. As a result of inter-study heterogeneity, meta-analyses were not possible for recurrence, complications or cost. CONCLUSION Low-level evidence exists that, compared with other blood conservation techniques, ICS reduces ATR and cost while not affecting complications. It does not appear to increase tumour recurrence post-prostatectomy, although follow-up durations were short. Small study sizes and short follow-ups mean conclusions cannot be drawn with regard to recurrence after nephrectomy or cystectomy. Randomized trials with long-term follow-up evaluating ICS in urology are required.

Abstract
Postpartum haemorrhage (PPH) is an obstetric emergency caused by excessive blood loss after delivery, which is the leading cause of maternal mortality worldwide. PPH can lead to volume depletion, hypovolemic shock, anaemia and ultimately death. The prevalence of PPH is disproportionately higher in low resource settings where there is limited access to skilled medical care and safe blood supplies. Current management strategies target both prevention and treatment of PPH however no alternatives currently exist to address the lack of safe blood supplies which are considered essential in emergency obstetrical care. Autotransfusion is used to salvage blood loss in a variety of clinical settings but has never been used in the context of vaginal delivery. We describe the development and testing of a novel device for the collection, filtration and autotransfusion of blood lost due to PPH. The prototype device is inexpensive and easily operated so that it may be practically deployed in low resource settings. The device is comprised of a blood collection drape, a pump apparatus, three leukocyte reduction filters and a reservoir for filtered blood. Preliminary testing demonstrates efficacy of microbial load reduction of up to 97.3%. To reduce cost and improve safety, the device is modular in design such that the drape, tubing, filters and transfusion bag may be stored sterile, used once and discarded; while the pump apparatus may be used indefinitely without the need for sterilisation. Preliminary results indicate the device confers a low cost and potentially effective means of collecting, pumping, filtering and returning blood to a patient following PPH in settings that lack safe blood supplies. This device shows promise as a method of stabilising patients suffering of PPH in low resource settings until definitive treatment is rendered with the ultimate goal of reducing maternal mortality globally.

Abstract
BACKGROUND CONTEXT Metastatic spine tumor surgery (MSTS) is associated with substantial blood loss, therefore leading to high morbidity and mortality. Although intraoperative cell salvage with leukocyte depletion filter (IOCS-LDF) has been studied as an effective means of reducing blood loss in other surgical settings, including the spine, no study has yet analyzed the efficacy of reinfusion of salvaged blood in reducing the need for allogenic blood transfusion in patients who have had surgery for MSTS. PURPOSE This study aimed to analyze the efficacy, safety, and cost-effectiveness of using IOCS-LDF in MSTS. STUDY DESIGN This is a retrospective controlled study. PATIENT SAMPLE A total of 176 patients undergoing MSTS were included in the study. METHODS All patients undergoing MSTS at a single center between February 2010 and December 2014 were included in the study. The primary outcome measure was the use of autologous blood transfusion. Secondary outcome measures included hospital stay, survival time, complications, and procedural costs. The key predictor variable was whether IOCS-LDF was used during surgery. Logistic and linear regression analyses were conducted by controlling variables such as tumor type, number of diseased vertebrae, approach, number and site of stabilized segments, operation time, preoperative anemia, American Society of Anesthesiologists (ASA) grade, age, gender, and body mass index (BMI). No funding was obtained and there are no conflicts of interest to be declared. RESULTS Data included 63 cases (IOCS-LDF) and 113 controls (non-IOCS-LDF). Intraoperative cell salvage with LDF utilization was substantively and significantly associated with a lower likelihood of allogenic blood transfusion (OR=0.407, p=.03). Intraoperative cell salvage with LDF was cost neutral (p=.88). Average hospital stay was 3.76 days shorter among IOCS-LDF patients (p=.03). Patient survival and complication rates were comparable in both groups. CONCLUSIONS We have demonstrated that the use of IOCS-LDF in MSTS reduces the need for postoperative allogenic blood transfusion while maintaining satisfactory postoperative hemoglobin. We recommend routine use of IOCS-LDF in MSTS for its safety, efficacy, and potential cost benefit.

Abstract
Background: HemoSep® is a commercial ultrafiltration and haemoconcentration device for the concentration of residual bypass blood following surgery. This technology is capable of reducing blood loss in cardiac and other types of “clean site” procedures, including paediatric surgery. Clinical feedback suggested that the device would be enhanced by including a sensor technology capable of discerning the concentration level of the processed blood product. We sought to develop a novel sensor that can, using light absorption, give an accurate estimate of packed cell volume (PCV). Materials and methods: A sensor-housing unit was 3D printed and the factors influencing the sensor’s effectiveness – supply voltage, sensitivity and emitter intensity - were optimised. We developed a smart system, using comparator circuitry capable of visually informing the user when adequate PCV levels (⩾35%) are attained by HemoSep® blood processing, which ultimately indicates that the blood is ready for autotransfusion. Results: Our data demonstrated that the device was capable of identifying blood concentration at and beyond the 35% PCV level. The device was found to be 100% accurate at identifying concentration levels of 35% from a starting level of 20%. Discussion: The sensory capability was integrated into HemoSep’s® current device and is designed to enhance the user’s clinical experience and to optimise the benefits of HemoSep® therapy. The present study focused on laboratory studies using bovine blood. Further studies are now planned in the clinical setting to confirm the efficacy of the device.

Abstract
Ruptured ectopic pregnancies are life-threatening emergencies, especially in developing countries, where many patients do not consult until rupture, sometimes with the patient already in hemorrhagic shock. In this situation, immediate blood transfusion is essential. Homologous blood products are not always available. Furthermore, homologous transfusion carries the risk of transmitting viruses such as HIV and hepatitis B and C. Autologous transfusion (intraoperative blood salvage) may thus be helpful. The authors present 6 cases of autologous transfusion performed at the Yaounde University Hospital (Cameroon) and recommend this method in developing countries where good quality blood cannot always be obtained rapidly.

Abstract
OBJECTIVE To describe the use and outcome following autologous blood transfusion (ABT) in dogs. DESIGN Retrospective study (January 2007-July 2012). SETTING Private veterinary referral center. ANIMALS Twenty-five dogs that underwent ABT secondary to thoracic or abdominal hemorrhage. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The hospital transaction database was searched using the keyword "autotransfusion" from January 2007 to July 2012. Data collected included signalment, body weight, etiology of hemorrhage, source and method of collection, volumes and method of ABT administration, use of anticoagulant, reported complications, and outcome. Twenty-five dogs were included for a total of 27 ABTs. Causes of hemorrhage included vascular trauma (14/25 dogs, 56%), ruptured tumor (8/25, 32%), and coagulopathy attributed to brodifacoum toxicosis (3/25, 12%). Autologous blood was collected from the abdominal (19/25, 76%), thoracic (5/25, 20%), or abdominal and thoracic cavities (1/25, 4%). Anticoagulant was added to the ABT blood in 13 of 25 (52%) cases. A median ABT volume of 29.3 mL/kg (range 2.9-406.9 mL/kg) was infused through either a 210 μm blood administration filter (21/27, 78%) or an 18 μm hemonate filter (6/27, 22%). Reported complications that may have been associated with ABT included hypocalcemia (4/17, 24%), hemolyzed serum (5/19, 26%), and prolonged coagulation times (4/5, 80%). These complications were considered of minimal clinical significance. Additional blood products were administered in 17 of 25 (68%) dogs. Seventeen (68%) dogs survived to discharge. Cause of death in the remaining cases was euthanasia or cardiac arrest secondary to uncontrollable hemorrhage. CONCLUSIONS ABT is an adjunct to volume replacement in dogs with thoracic or abdominal hemorrhage secondary to vascular trauma, ruptured tumor, or anticoagulant rodenticide toxicosis. ABT may be used as bridge to definitive hemorrhage control, particularly when other blood products are not available or affordable. Complications may include hypocalcemia, prolonged coagulation times, and hemolysis.

Abstract
Inflammatory lung injury is an inevitable consequence of cardiac surgery with cardiopulmonary bypass. The lungs are particularly susceptible to the effects of the systemic inflammatory response to cardiopulmonary bypass. This insult is further exacerbated by a pulmonary ischemia-reperfusion injury after termination of bypass. Older patients and those with pre-existing lung disease will clearly be less tolerant of any lung injury and more likely to develop respiratory failure in the postoperative period. A requirement for prolonged ventilation has implications for morbidity, mortality, and cost of treatment. This review contains a summary of recent interventions and changes of practice that may reduce inflammatory lung injury after cardiac surgery. The review also focuses on a number of general aspects of perioperative management, which may exacerbate such injury, if performed poorly.

Abstract
The purpose of this study was to evaluate the efficacy and safety of postoperative wound drain salvage and autotransfusion system in haemophilic patients undergoing elective total knee arthroplasty (TKA). No literature exists on reinfusing drained blood in patient with haemophilia undergoing TKA. Eighty-eight knees of 66 patients received cemented TKA due to end-stage haemophilic arthropathy (group I; with autotransfusion in 59 knees, group II; without autotransfusion in 29 knees). In group I, the postoperative shed blood was transfused within 6 h after surgery. The amount of blood drainage and reinfused blood, rate and amount of allogenic transfusion, postoperative change of haemoglobin level, prothrombin time (PT) and activated partial thromboplastin time were analysed. The mean postoperative blood drainage was 932 ± 479 mL in group I and 830 ± 492 mL in group II (P > 0.05). The mean volume of blood reinfused was 530 ± 265 mL in group I. Allogenic transfusion was needed in six knees (10.2%) of group I and eight knees (27.6%) of group II (P = 0.036). The mean volume of allogenic transfusion was 480 ± 49 mL in group I and 1041 ± 691 mL in group II (P > 0.05). Changes of all the laboratory results before and after TKA showed no statistically significant difference except PT was prolonged in group I (P = 0.008) at postoperative day 1. Moreover, there was no significant complication related to either reinfusion or allogenic transfusion in both groups. This study showed that reinfusion of drained blood is a simple, safe and efficacious method in patients with haemophilia undergoing TKA.

Abstract
BACKGROUND There is concern that salvaged blood has the potential to activate the coagulation system, which might place patients at risk of thrombotic complications. The aim of this study was to determine whether transfusion of salvaged blood after total knee arthroplasty (TKA) would lead to procoagulopathic changes as measured by thromboelastography (TEG) and furthermore if washing would reduce this risk. STUDY DESIGN AND METHODS Twenty-two patients undergoing TKA were enrolled. Control samples were venous blood samples taken before surgery. Test samples were created by mixing the control samples with postoperatively salvaged blood, either washed or unwashed. TEG profiles were measured, noting the time to initiate clotting (R), the time of clot formation (K), the angle of clot formation (α-angle), and the maximum amplitude (clot strength [MA]). RESULTS The changes in the coagulation profile from control samples to test samples were consistent for both the washed and the unwashed groups: R time decreased, MA decreased, and K and α-angle remained the same. However, the changes were more pronounced in the unwashed group than the washed group, with a 61% decrease in R time compared with 14%, and a 26% decrease in MA compared with 6%. CONCLUSION The addition of salvaged blood to the patient's preoperative blood resulted in decreased MA as well as decreased R time. This suggests that the reinfusion of postoperatively salvaged washed or unwashed blood after TKA favors a change toward a more hypocoagulable state, and washing appears to reduce this effect.

Abstract
Extensive literature has been published evaluating the use of cell salvage in cardiac surgery. However, the most recently published blood management guidelines do not give unequivocal direction on the use of cell salvage in cardiac surgical procedures and neither do recent meta-analyses and randomized controlled trials. In part, this reflects variation in the details of how cell salvage is used, including the specific equipment chosen. Consensus on the optimal approach to cell salvage would be helpful. A well-designed, appropriately powered, multicenter study could then be carried out with one or more specified devices to evaluate the efficacy of this agreed approach to cell salvage in the cardiac surgical environment.

Abstract
Cell concentrating and washing techniques are widely accepted and believed to be beneficial to cardiac surgery patients. During cell processing, platelets, proteins, and clotting factors are wasted as the plasma is washed away by saline. Beneficial and costly plasma constituents are sacrificed for the sake of removing potentially harmful drugs, debris, and naturally activated cells and chemical mediators. An interactive Microsoft Excel spreadsheet was designed to input patient and autotransfusion system (ATS) reservoir blood values, processed centrifugal bowl data, and hospital allogeneic blood product concentration and cost information. The spreadsheet calculates the number of wasted platelets, grams of protein, and milligrams of fibrinogen. The calculator further estimates the number of units and cost of allogeneic blood products needed to replace the wasted blood components. The simulation allows for variable levels of platelet activation and protein removal during centrifugal cell processing. Specific case scenarios may be simulated with the calculator. If a known volume of residual extracorporeal circuit blood with a known hematocrit, platelet count, and protein concentration is diverted to the ATS reservoir to be processed and washed after bypass, the number of units of fresh frozen plasma, platelet packs, and albumin concentrate needed to replace the wasted proteins and platelets may be calculated. When typical end-bypass patient and blood bank product values are input, the cost to replace the wasted blood components in 1550 mL of residual circuit blood with allogeneic blood products is about US $2097. There are risks and costs associated with replacing the platelets, proteins, and clotting factors wasted during cell washing compared with other techniques such as whole blood ultrafiltration.

Abstract
UNLABELLED The coagulation-fibrinolytic profile during cardiopulmonary bypass (CPB) has been widely documented. However, less information is available on the possible persistence of these alterations when autotransfusion is used in management of perioperative blood loss. This study was designed to explore the influence of autotransfusion management on intravascular fibrin degradation and postoperative transfusions. Thirty patients, undergoing elective primary isolated coronary bypass grafting, were randomly allocated either to a control group (group A; n=15) or an intervention group (group B; n=15) in which mediastinal and residual CPB blood was collected and processed by a continuous autotransfusion system before re-infusion. Intravascular fibrin degradation as indicated by D-dimer generation was measured at five specific intervals and corrected for hemodilution. In addition, chest tube drainage and need for homologous blood were monitored. D-dimer generation increased significantly during CPB in group A, from 312 to 633 vs. 291 to 356 ng/mL in group B (p = .001). The unprocessed residual blood (group A) revealed an unequivocal D-dimer elevation, 4131 +/- 1063 vs. 279 +/- 103 ng/mL for the processed residual in group B (p < .001). Consequently, in the first post-CPB period, the intravascular fibrin degradation was significantly elevated in group A compared with group B (p = .001). Twenty hours postoperatively, no significant difference in D-dimer levels was detected between both groups. However, a significant intra-group D-dimer elevation pre- vs. postoperative was noticed from 312 to 828 ng/mL in group A and from 291 to 588 ng/mL in group B (p < .01 for both). Postoperative chest tube drainage was higher in the patients from group A, which also had the highest postoperative D-dimer levels. Patients in group A perceived a higher need for transfusions of red cells suspensions postoperatively. These data clearly indicate that autotransfusion management during and after CPB suppresses early postoperative fibrin degradation. KEYWORDS cardiopulmonary bypass, cardiotomy suction, coronary surgery, autotransfusion, fibrin degradation.

Abstract
Controversy still exists on the validity of processing a partial bowl during the collection of shed blood lost through surgery during cell salvaging. The purpose of this study was to assess the quality of red blood cells produced from a partial bowl of autologous suctioned blood using the Haemonetics Cell Saver 5. Suctioned blood was collected from 17 patients undergoing cardiac surgery. A partially filled cell saver bowl was washed with 1500 mL of NaCl. Reservoir and processed blood samples were examined for potassium, leukocytes, hematocrit, platelets, and plasma-free hemoglobin and then compared with 22 previously studied full bowls. Results are summarized in the table below: In conclusion, the Haemonetics Cell Saver 5 can produce a quality product from washing a partial bowl with a better washout of white blood cells compared with a full bowl. However, there is a reduction in red blood cell recovery.
