Objective To explore ability of deformation ,small deformation, orientation and in vivo half-life of erythrocytes following intraoperative autotransfusion by ZITI-3000 cell saving system (Jingjing medical facility corporation, Beijing). Methods Twenty consecutive patients undergoing scheduled off-pump coronary artery bypass grafting (CABG) were divided into two groups according to intraoperative autotransfusion, experimental group(n=10): intraoperative autotransfusion was performed; control group (n=10): intraoperative autotransfusion wasn’t used. Laser diffractometer was used to measure deformation index(DI), small deformation index[(DI)d.max], and orientation index [(DI)or.max],and chromium51 istope labeling technique was used to measure half-life of erythrocytes (51C1/2) of processed and unprocessed in vivo. Results There were no significant difference in DI, (DI)d.max, (DI)or.max and 51C1/2 in vivo between experimental group and control group. Conclusion Intraoperative autotransfusion has no significant effect on erythrocytes’s ability of DI, (DI)d.max, (DI)or.max and 51C1/2 in vivo in off-pump CABG.
The incidence of cardiovascular disease remains high, and surgery is an important measure for the treatment of cardiovascular disease. However, cardiovascular surgery is complicated and difficult, and it is one of the departments with the highest rate of allogeneic blood transfusion. Allogeneic blood transfusion significantly increases the complications and mortality of patients, while autologous blood transfusion can effectively reduce allogeneic blood transfusion and adverse reactions. Autologous plateletpheresis technology is a popular autotransfusion method in recent years. This article reviews the autologous plateletpheresis technology and its clinical application in cardiovascular surgery.
Objective To investigate the risk factors of perioperative red blood cells transfusion for coronary artery bypass grafting (CABG) surgery. Method We retrospectively analyzed the clinical data of 534 patients underwent CABG in our hospital from January to March 2014 year. Those patients were divided into two groups:an on-pump coronary artery bypass grafting group (on-pump group) and an off-pump coronary artery bypass grafting group (off-pump group). There were 185 males and 54 females with a mean age of 59.1±9.4 years in the on-pump group. There were 233 males and 62 females with a mean age of 60.3±8.5 years in the off-pump group. Preoperative data, the relative parameters of extracorporeal circulation, the quantity of red blood cells transfusion of those two groups were compared. risk factors associated with red blood cells transfusion were evaluated by multivariate logistic regression analysis. Results The risk factors of perioperative red blood cells transfusion were age (OR=1.04, 95% CI 1.02-1.07, P=0.001) , weight (OR=0.95, 95% CI 0.93-0.97, P<0.001) , smoking (OR=0.61, 95% CI 0.39-0.94, P=0.027) , preoperative level of HCT (OR=0.90, 95% CI 0.85-0.96, P=0.001) and cardiopulmonary bypass (CPB) (OR=4.90, 95% CI 3.11-7.71, P<0.001) . During CPB, the nadir hemoglobin (nHb) (OR=0.63, 95% CI 0.47-0.84, P=0.002) was the only independent risk factor of red blood cell transfusion. Conclusions Age, weight, non-smoking, preoperative level of HCT, CPB are the risk factors for patients underwent CABG perioperatively and the lowest level of Hb in CPB is an independent risk factor of perioperative red blood cells transfusion.
Objective To explore the methods and effect of venous retransfusion of ascites on the treatment of the complicated patients with Budd-Chiari syndrome.Methods Eighteen complicated and (or) recrudescent patients with Budd-Chiari syndrome were treated by venous retransfusion of ascites between March 2006 and July 2009. The changes in abdominal girth, body weight, the urine volume of 24 h, liver function, renal function, and serum electrolyte measurements before and after treatment were compared. Results After retransfusion of 5 000 ml to 7 800 ml (mean 6 940 ml) ascites, the abdominal girth of patients decreased (Plt;0.05), the urine volume of 24 h tended to normal and during which no serious side-effect happened. The levels of serum BUN, CREA, prothrombin time (PT), and activated partial thromboplastin time (APTT) decreased significantly (Plt;0.05), furthermore the levels of total albumen and albumin increased significantly (Plt;0.05). The changes of serum electrolyte measurements were not significant (Pgt;0.05). The follow-up period for all the patients was in the range of 4 to 37 months (mean 19 months). Then 12 patients were treated by the second operation at 3-6 months after discharge. Conclusions The ascites retransfusion provides a safe and effective treatment option for patients with refractory ascites, and yields a higher likelihood of discharge compared with conventional paracentesis. It is useful in improving quality of life and winning the operational chance for such as patients with complicated Budd-Chiari syndrome.
ObjectiveTo investigate the correlation between perioperative blood transfusion and hepatic postoperative infection. MethodsOne hundred and thirty patients undergoing hepatic operation were analyzed retrospectively on the relation of perioperative blood transfusion with postoperative infective morbidity and mortality in the period 1989-1999. The patients were divided into blood transfused group and nontransfused group. The major or minor hepatectomy was performed in 53 patients with hepatic malignancy and benign diseases. ResultsIn the blood transfused group, the infective morbidity and perioperative mortality rate was 38.5% and 16.7% respectively, significantly higher than those in nontransfused group (11.5% and 3.8% respectively), P＜0.05. The total lymphocyte count was lower in transfused group than that in nontransfused group. The postoperative antibiotics used time and length of hospital stay were (9.7±4.2) days and (18.7±13.1) days respectively in transfused group than those in nontransfused group (5.3±2.3) days and (12.7±5.2) days respectively. ConclusionThe results suggest that hepatic postoperative infective morbidity and mortality are related with perioperative blood transfusion. Any strategy to reduce blood loss in liver surgery and decrease blood transfusion would be helpful to lower postoperative infective morbidity.
ObjectiveTo understand the adverse effects of perioperative red blood cells (RBC) transfusion on patients after pancreaticoduodenectomy (PD) so as to provide ideas for reducing postoperative complications and improving prognosis. MethodThe relevant literatures at home and abroad in recent years about studies of perioperative RBC transfusion on postoperative complications (focusing on pancreatic fistula and infection) and prognosis of patients with PD were reviewed. ResultsThe rates of postoperative complications and perioperative RBC transfusion after PD were still higher. The perioperative RBC transfusion might increase the rate of postoperative complications, promote early tumor recurrence, and shorten the disease-free survival and overall survival. At present, with the progress of technology, the perioperative RBC transfusion rate was decreasing. At the same time, with the accelerated development of new blood transfusion technologies such as freeze-drying and refrigeration, the decline rate was still expected to be increased. ConclusionsPerioperative RBC transfusion in PD might have adverse effects on postoperative complications and prognosis. Although further research is still needed to explore its necessary connection, this adverse effect needs to be paid enough attention in clinical practice. Early identification of risk factors, strict transfusion indications and minimizing amount or concentration of RBC transfusion might help to avoid or reduce RBC transfusion and minimize its adverse effects.
OBJECTIVE: To observe the clinical results in the anterior stabile operation of spinal fracture using red blood salvage. METHODS: Nineteen cases with spinal fracture were performed the anterior decompress operation. Blood cell salvage were used during operation. Other 20 cases were also reviewed as control group, who were received the same operation without blood cell salvage. RESULTS: In the 19 cases, average volume of autologous transfusion was 536 ml. Only two cases had homologous transfusion requirements. In the control group, all cases needed homologous transfusion (averaged 947 ml). CONCLUSION: In the anterior decompress operation, the intraoperative blood salvage is highly effective in reducing transfusion and also improves the security of operation
ObjectiveTo analyze and reduce the defects in nursing records for blood transfusion by continuous quality improvement (CQI) method, in order to prevent blood transfusion related medical disputes. MethodsIn October 2014, CQI team was established to analyze the reason for transfusion record defects and make standardized process and quality monitoring forms for nursing record of blood transfusion. Six months after the implementation of CQI, 40 records were randomly selected before the CQI implementation (April to September 2014) and after the implementation (April to September 2015) for comparison and analysis. ResultAfter 6 months of implementation of CQI, nursing record defects of blood transfusion decreased significantly from 228 to 55 items. ConclusionUsing CQI method can effectively reduce nursing record defects of blood transfusion. CQI can also improve the quality of nursing records and prevent medical disputes caused by blood transfusion.
Objective To investigate the effects of component blood transfusion combined with heparin therapy on coagulation function and clinical outcomes in pregnant women with acute disseminated intravascular coagulation (DIC). Methods A retrospective analysis was conducted on the clinical data of 65 pregnant women with acute DIC who were treated in Obstetrics Department of Luzhou People’ s Hospital between March 2020 and March 2022. Pregnant women treated with component blood transfusion were included in the control group, while those treated with component blood transfusion combined with heparin were included in the observation group. Before and after treatment, the DIC scoring system was used for score evaluation. Coagulation function indicators and routine blood indicators were compared between the two groups of pregnant women. Adverse clinical outcomes and adverse reactions were observed in both groups of pregnant women. Results The study enrolled 65 pregnant women, comprising 30 in the observation group and 35 in the control group. Before treatment, there was no statistical difference in DIC score, coagulation function indicators, or routine blood indicators between the two groups (P>0.05). After treatment, the DIC score, prothrombin time, activated partial thromboplastin time, thrombin time, and D-dimer significantly decreased in both groups (P<0.05), and the above indicators in the observation group [3.39±0.48, (13.28±2.28) s, (24.68±2.06) s, (14.27±1.82) s, and (2.23±0.88) mg/L, respectively] were lower than those in the control group [4.11±1.56, (15.02±2.45) s, (26.79±3.18) s, (15.61±1.91) s, and (2.87±0.74) mg/L, respectively] (P<0.05). The levels of fibrinogen, platelet count, hemoglobin, and hematocrit significantly increased in both groups (P<0.05), and the levels in the observation group [(4.29±1.05) g/L, (175.36±20.46)×109/L, (84.09±7.27) g/L, and (25.49±3.13)%, respectively] were higher than those in the control group [(3.44±1.27) g/L, (145.77±21.12)×109/L, (76.58±7.13) g/L, and (23.03±3.05)%, respectively] (P<0.05). The observation group had a lower incidence rate of adverse clinical outcomes compared to the control group (33.3% vs. 74.3%, P<0.05). The incidence rates of adverse reactions were not statistically different between the two groups (P>0.05). Conclusions Component blood transfusion combined with heparin therapy for pregnant women with acute DIC can effectively improve their coagulation function, reduce the risk of bleeding, and further improve adverse clinical outcomes such as postpartum hemorrhage and hysterectomy. Additionally, this treatment approach demonstrates a high safety profile.
ObjectiveTo review the perioperative blood management (PBM) of total knee arthroplasty (TKA) and total hip arthroplasty (THA).MethodsRecent researches on PBM for TKA and THA were comprehensively read and summarized. Then the advantages and disadvantages of various measures together with the clinical experience of West China Hospital of Sichuan University were evaluated from three aspects, including optimizing hematopoiesis, reducing blood loss and blood transfusion, which could provide a basis for clinical selection.ResultsThere are many PBM methods in TKA and THA, among which the optimization of hematopoiesis mainly includes the application of perioperative iron and erythropoietin. Measures to reduce bleeding include the use of tourniquet, intraoperative controlled hypotension, and perioperative antifibrinolytic agents. Autologous blood transfusion includes preoperative autologous blood donation, hemodilution and cell salvage. Allogeneic blood transfusion is the ultimate treatment for anemia. The application of erythropoietin combined with iron therapy for blood mobilization before surgery together with intraoperative controlled hypotension for bleeding control and the multiple use of tranexamic acid can achieve satisfactory clinical results.ConclusionIn the perioperative period of TKA and THA, single or multiple use of different blood management measures should be considered carefully according to the physical and economic conditions of patients individually, so as to reduce the blood loss and allogeneic blood transfusion optimally, and finally accelerate the recovery of patients.
