European journal of medical research. 2024;29(1):108
Abstract
PURPOSE To assess the effectiveness of autologous blood patch intraparenchymal injection during CT-guided lung biopsies with a focus on the incidence of pneumothorax and the subsequent requirement for chest tube placement. METHODS A comprehensive search of major databases was conducted to identify studies that utilized autologous blood patches to mitigate the risk of pneumothorax following lung biopsies. Efficacy was next assessed through a meta-analysis using a random-effects model. RESULTS Of the 122 carefully analyzed studies, nine, representing a patient population of 4116, were incorporated into the final analysis. Conclusion deduced showed a noteworthy reduction in the overall incidence of pneumothorax (RR = 0.65; 95% CI 0.53-0.80; P = 0.00) and a significantly decline in the occasion for chest tube placement due to pneumothorax (RR = 0.45; 95% CI 0.32-0.64; P = 0.00). CONCLUSIONS Utilizing autologous blood patch intraparenchymal injection during the coaxial needle retraction process post-lung biopsy is highly effective in diminishing both the incidence of pneumothorax and consequent chest tube placement requirement.

Abstract
INTRODUCTION Despite the increasing amount of evidence supporting its use, cell salvage (CS) remains an underutilized resource in operative trauma care in many hospitals. We aim to evaluate the utilization of CS in adult trauma patients and associated outcomes to provide evidence-based recommendations. METHODS A systematic review was conducted using PubMed, Google Scholar, and CINAHL. Articles evaluating clinical outcomes and the cost-effectiveness of trauma patients utilizing CS were included. The primary study outcome was mortality rates. The secondary outcomes included complication rates (sepsis and infection) and ICU-LOS. The tertiary outcome was the cost-effectiveness of CS. RESULTS This systematic review included 9 studies that accounted for a total of 1119 patients that received both CS and allogeneic transfusion (n = 519), vs allogeneic blood transfusions only (n = 601). In-hospital mortality rates ranged from 13% to 67% in patients where CS was used vs 6%-65% in those receiving allogeneic transfusions only; however, these findings were not significantly different (P = .21-.56). Similarly, no significant differences were found between sepsis and infection rates or ICU-LOS in those patients where CS usage was compared to allogeneic transfusions alone. Of the 4 studies that provided comparisons on cost, 3 found the use of CS to be significantly more cost-effective. CONCLUSIONS Cell salvage can be used as an effective method of blood transfusion for trauma patients without compromising patient outcomes, in addition to its possible cost advantages. Future studies are needed to further investigate the long-term effects of cell salvage utilization in trauma patients.

Cai, Y., He, X., Cheng, Q.
African health sciences. 2023;23(3):514-520
Abstract
BACKGROUND To probe into the influences of different blood conservation techniques on the postoperative coagulation function and prognosis of elderly patients receiving Total Hip Arthroplasty (THA). METHODOLOGY A total of 60 patients were randomly divided into Autologous Blood Transfusion (ABT) group (n=30) and ANH group (n=30). For patients in the ABT group, an autologous blood recovery machine was used to recover, wash and filter the surgical field blood. For those in the Acute Isovolumic Hemodilution (ANH) group, blood was collected preoperatively from the central vein and stored in a citrate anticoagulant blood storage bag, while the same amount of hydroxyethyl starch was injected into the peripheral vein to dilute the blood. After Mai bleeding steps of the operation were completed, the autologous blood of patients was transfused back in both groups. The clinical indicators of patients in each group were observed. RESULTS 48 h after operation, the ANH group obtained a higher level of hemoglobin (Hb), shorter Activated Partial Thromboplastin Time (APTT), and a lower expression rate of platelet activating factor CD62P than the ABT group. CONCLUSION The ANH group exhibits higher content of hemoglobin and fewer platelet (Plt)activating factors produced than the ABT group, while no significant difference in the shortened length of hospital stays is found.

BMC geriatrics. 2023;23(1):689
Abstract
OBJECTIVE To explore the effect of acute normovolemic hemodilution (ANH) on the anesthetic effect, plasma concentration, and postoperative recovery quality in elderly patients undergoing spinal surgery. METHODS A total of 60 cases of elderly patients aged 65 to 75 years who underwent elective multilevel spinal surgery were assigned randomly into the ANH group (n = 30) and control group (n = 30). Hemodynamic and blood gas analysis indexes were observed and recorded before ANH (T(1)), after ANH (T(2)), immediately after postoperative autologous blood transfusion (T(3)), 10 min (T(4)), 20 min (T(5)), 30 min (T(6)), 40 min (T(7)), and 50 min (T(8)) after the transfusion, and at the end of the transfusion (i.e., 60 min; T(9)). At T(3 ~ 9), bispectral index (BIS) and train-of-four (TOF) stimulation were recorded and the plasma propofol/cisatracurium concentration was determined. The extubation time and recovery quality were recorded. RESULTS The ANH group presented a lower MAP value and a higher SVV value at T(2), and shorter extubation and orientation recovery time (P < 0.05) compared with the control group. BIS values at T(8) and T(9) were lower in the ANH group than those in the control group (P < 0.05). TOF values at T(7 ~ 9) were lower in the ANH group than those in the control group (P < 0.05). There were no statistically significant differences in the postoperative plasma concentrations of propofol and cisatracurium between the groups (P > 0.05). CONCLUSION During orthopedic surgery, the plasma concentration of elderly patients is increased after autologous blood transfusion of ANH, and the depth of anesthesia and muscle relaxant effect are strengthened, thus leading to delayed recovery of respiratory function and extubation.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a significant cause of oncologic mortality worldwide. Liver transplantation represents a curative option for patients with significant liver dysfunction and absence of metastases. However, this therapeutic option is associated with significant blood loss and frequently requires various transfusions and intraoperative blood salvage for autotransfusion (IBS-AT) with or without a leukocyte reduction filter. This study aimed to analyze available evidence on long-term oncologic outcomes of patients undergoing liver transplantation for HCC with and without IBS-AT. METHODS Per PRISMA guidelines, a systematic review of keywords "Blood Salvage," "Auto-transfusion," "Hepatocellular carcinoma," and "Liver-transplant" was conducted in PubMed, EMBASE, and SCOPUS. Studies comparing operative and postoperative outcomes were screened and analyzed for review. RESULTS Twelve studies totaling 1704 participants were included for analysis. Length of stay, recurrence rates, and overall survival were not different between IBS-AT group and non IBS-AT group. CONCLUSION IBS-AT use is not associated with increased risk of recurrence in liver transplant for HCC even without leukocyte filtration. Both operative and postoperative outcomes are similar between groups. Comparison of analyzed studies suggest that IBS-AT is safe for use during liver transplant for HCC.

Wu, Y., He, J., Han, X., Xu, Q., Dai, H., Wu, J.
The Journal of international medical research. 2023;51(11):3000605231206963
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.

Walton, T. J., Huntley, D., Whitehouse, S. L., Davies, J., Wilson, M. J., Hubble, M. J. W., Howell, J. R., Kassam, A. M.
The bone & joint journal. 2023;105-b(10):1038-1044
Abstract
AIMS: The aim of this study was to perform a systematic review of the evidence for the use of intraoperative cell salvage in patients undergoing revision hip arthroplasty, and specifically to analyze the available data in order to quantify any associated reduction in the use of allogenic blood transfusion, and the volume which is used. METHODS An electronic search of MEDLINE (PubMed), Embase, Scopus, and the Cochrane Library was completed from the date of their inception to 24 February 2022, using a search strategy and protocol created in conjunction with the PRISMA statement. Inclusion criteria were patients aged > 18 years who underwent revision hip arthroplasty when cell salvage was used. Studies in which pre-donated red blood cells were used were excluded. A meta-analysis was also performed using a random effects model with significance set at p = 0.05. RESULTS Of the 283 studies which were identified, 11 were included in the systematic review, and nine in the meta-analysis. There was a significant difference (p < 0.001) in the proportion of patients requiring allogenic transfusion between groups, with an odds ratio of 0.331 (95% confidence interval (CI) 0.165 to 0.663) associated with the use of cell salvage. For a total of 561 patients undergoing revision hip arthroplasty who were treated with cell salvage, 247 (44.0%) required allogenic transfusion compared with 418 of 643 patients (65.0%) who were treated without cell salvage. For those treated with cell salvage, the mean volume of allogenic blood which was required was 1.95 units (390 ml) per patient (0.7 to 4.5 units), compared with 3.25 units (650 ml) per patient (1.2 to 7.0 units) in those treated without cell salvage. The mean difference of -1.91 units (95% CI -4.0 to 0.2) in the meta-analysis was also significant (p = 0.003). CONCLUSION We found a a significant reduction in the need for allogenic blood transfusion when cell salvage was used in patients undergoing revision hip arthroplasty, supporting its routine use in these patients. Further research is required to determine whether this effect is associated with types of revision arthroplasty of differing complexity.

Abstract
BACKGROUND AND OBJECTIVES Factors associated with external ventricular catheter tract hemorrhage (CTH) are well studied; whether CTH adversely influence outcomes after intracerebral hemorrhage (sICH), however, is poorly understood. We therefore sought to evaluate the association between CTH and sICH outcomes. METHODS We performed a post hoc analysis of the Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage trial. The exposure was CTH and evaluated on serial computed tomography scans between admission and randomization (approximately 72 hours). The primary outcomes were a composite of death or major disability (modified Rankin Score >3) and mortality alone, both assessed at 6 months. Secondary outcomes were functional outcomes at 30 days, permanent cerebrospinal fluid (CSF) shunt placement, any infection, and ventriculitis. We performed logistic regression adjusted for demographics, comorbidities, sICH characteristics, and treatment assignment, for all analyses. RESULTS Of the 500 patients included, the mean age was 59 (SD, ±11) years and 222 (44%) were female. CTH occurred in 112 (22.4%) patients and was more common in minority patients, those on prior antiplatelet therapy, and patients who had more than 1 external ventricular drain placed. The end of treatment intraventricular hemorrhage volume was higher among patients with CTH (11.7 vs 7.9 mL, P = .01), but there were no differences in other sICH characteristics or the total duration of external ventricular drain. In multivariable regression models, CTH was not associated with death or major disability (odds ratio, 0.7; 95% CI: 0.4-1.2) or death alone (odds ratio, 0.8; 95% CI, 0.5-1.4). There were no relationships between CTH and secondary outcomes including 30-day functional outcomes, permanent CSF shunt placement, any infection, or ventriculitis. CONCLUSION Among patients with sICH and large intraventricular hemorrhage, CTH was not associated with poor sICH outcomes, permanent CSF shunt placement, or infections. A more detailed cognitive evaluation is needed to inform about the role of CTH in sICH prognosis.

Journal of clinical anesthesia. 2023;87:111082
Abstract
STUDY OBJECTIVE To investigate whether large volume acute normovolemic hemodilution (L-ANH), compared with moderate acute normovolemic hemodilution (M-ANH), can reduce perioperative allogeneic blood transfusion in patients with intermediate-high risk of transfusion during cardiac surgery with cardiopulmonary bypass (CPB). DESIGN Prospective randomized controlled trial. SETTING University hospital. PATIENTS Patients with transfusion risk understanding scoring tool ("TRUST") ≥2 points undergoing cardiac surgery with CPB in the Second Affiliated Hospital of Zhejiang University from May 2020 to January 2021 were included. INTERVENTIONS The patients were randomly assigned with a 1:1 ratio to M-ANH (5 to 8 mL/kg) or L-ANH (12 to 15 mL/kg). MEASUREMENTS The primary outcome was perioperative red blood cell (RBC) transfusion units. The composite outcome included new-onset atrial fibrillation, pulmonary infection, cardiac surgery associated acute kidney injury (CSA-AKI) class ≥2, surgical incision infection, postoperative excessive bleeding, and resternotomy. MAIN RESULTS Total 159 patients were screened and 110 (55 L-ANH and 55 M-ANH) were included for final analysis. Removed blood volume of L-ANH is significantly higher than M-ANH (886 ± 152 vs. 395 ± 86 mL, P < 0.001). Perioperative RBC transfusion was median 0 unit ([25th, 75th] percentiles: 0-4.4) in M-ANH group vs. 0 unit ([25th, 75th] percentiles: 0-2.0) in L-ANH group (P = 0.012) and L-ANH was associated with lower incidence of transfusion (23.6% vs. 41.8%, P = 0.042, rate difference: 0.182, 95% confidence interval [0.007-0.343]). The incidence of postoperative excessive bleeding was significantly lower in L-ANH vs. M-ANH (3.6% vs. 18.2%, P = 0.029, rate difference: 0.146, 95% confidence interval [0.027-0.270]) without significant difference for other second outcomes. The volume of ANH was inversely related to perioperative RBC transfusion units (Spearman r = -0.483, 95% confidence interval [-0.708 to -0.168], P = 0.003), and L-ANH in cardiac surgery was associated with a significantly reduced risk of perioperative RBC transfusion (odds ratio: 0.43, 95% confidence interval: 0.19-0.98, P = 0.044). CONCLUSIONS Compared with M-ANH, L-ANH during cardiac surgery inclined to be associated with reduced perioperative RBC transfusion and the volume of RBC transfusion was inversely proportional to the volume of ANH. In addition, LANH during cardiac surgery was associated with a lower incidence of postoperative excessive bleeding.

Iyer, N. S., Khanuja, K., Roman, A., Al-Kouatly, H. B.
American journal of obstetrics & gynecology MFM. 2023;:101257
Abstract
OBJECTIVE Excess blood loss from obstetrical hemorrhage requires transfusion of donor blood, a finite resource. Intraoperative cell salvage collects a patient's own blood that has been lost during cesarean delivery and returns it to their own circulation. We performed a meta-analysis to examine the perioperative outcomes in patients receiving cell salvage at the time of cesarean delivery. DATA SOURCES Scopus, PubMed, Cochrane Central Register of Controlled Trials, Ovid Medline, and clinicaltrials.gov were searched from database inception through October 2023. STUDY CRITERIA Randomized controlled trials comparing the use of cell salvage to standard of care during cesarean delivery. STUDY APPRAISAL AND SYNTHESIS METHODS Two authors independently extracted data. PRISMA guidelines were used for data extraction and quality assessment. Primary outcomes were the rate of donor blood transfusion and change in hemoglobin level. Secondary outcomes included transfusion reaction, amniotic fluid embolism, and length of hospital stay. Results were summarized as weighted mean difference (MD) or risk ratio (RR) with associated 95% confidence intervals. Heterogeneity was measured using Higgins I(2). RESULTS A total of four RCTs (n=3231) comparing cell salvage to standard care during cesarean delivery met inclusion criteria. Primary analysis showed a significant decrease in receiving allogeneic blood transfusion with intraoperative cell salvage use versus standard care (OR 0.61, 95% CI [0.41,0.92]), with no change in hemoglobin drop (MD -1.03, 95% CI [-2.78,-0.72]). Secondary outcomes showed no difference in transfusion reaction (OR 0.56, 95% CI [0.06,5.59]), and length of hospital stay (MD -1.90, 95% CI [-4.85,1.06]). No cases of amniotic fluid embolism were reported among the 1620 patients who received cell salvage. CONCLUSION Use of cell salvage during cesarean delivery reduced the overall need for allogeneic blood transfusion without increasing the risk of complications including no cases of amniotic fluid embolism.
