UNLABELLED:To evaluate the effect of multidisciplinary blood management strategy in adults patients undergoing valvular heart surgery.METHODS:A multidisciplinary patient blood management (PBM) strategy was instituted in Fuwai Hospital since January 2009. It includes Establishment of a multidisciplinary blood transfusion management team and designation of a coordinator; Enactment perioperative transfusion triggers (Hb < 80 g/L) for adults patients undergoing cardiac surgery; recommendation of antifibrinolytics, cell salvage, reduced cardiopulmonary bypass circuit; setting up Blood Consumption Announcement and Scoring System, which regularly publishes notifications of blood volume consumed per case, per single procedure and per surgeon. Clinical date before and after multidisciplinary patient blood management strategy will be presented.RESULTS:A total of 3 951 consecutive patients underwent Valvular Heart Surgery were analyzed. 1 713 cases were in pre-PBM group, and 2 238 cases were in post-PBM group. Both incidence and average units of allogeneic red blood cell transfusion perioperatively in post-PBM group were decreased (28.5% vs 75.3%, P = 0.000, and 1.2 U vs 4.0 U, P = 0.000). The postoperative length of stay in hospital and incidence of pneumonia were reduced in post-PBM group (8.2 d vs 10.5 d, P = 0.02, and 2.7% vs 3.5%, P = 0.04). The post-PBM group had lower in-hospital mortality (0.6% vs 1.2%, P = 0.000).CONCLUSION:Multidisciplinary patient blood management strategy significantly reduced blood transfusion, morbidity and mortality in patients underwent valvular heart surgery. It save plenty of blood resources.

The Chinese Hypertension Intervention Efficacy Study (CHIEF) is a multi-centre randomized controlled clinical trial comparing the effects of amlodipine+angiotensin II receptor blocker and amlodipine+diuretics on the incidence of cardiovascular events, represented as a composite of non-fatal stroke, non-fatal myocardial infarction and cardiovascular death events in high-risk Chinese hypertensive patients. The study also evaluates the long-term effects of lipid-lowering treatment and lifestyle modification. From October 2007 to October 2008, 13,542 patients were enrolled into the study in 180 centres in China. Patients will be followed up for 4 years. There was no difference in baseline characteristics between the two blood pressure arms.

OBJECTIVE:To determine the normal values for thromboelastography (TEG) in Chinese healthy adult volunteers residing in Beijing for over three years and compare them with those of the manufacturer's.METHODS:A total of 137 healthy adult volunteers were enrolled from June 2010 to August 2010. The technique was standardized with citrated blood and kaolin activator. And a Haemoscope 5000 device was employed. The TEG parameters analyzed were R, K, α, maximal amplitude (MA), LY30 and coagulation index (CI). All volunteers underwent the tests of prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and plasma fibrinogen level with the same blood sample.RESULTS:The reference ranges of 95% for 137 volunteers were R: 3.8 - 8.4 min, K: 0.8 - 3.3 min, α-Angle: 46.2 - 76.2°, MA: 50.0 - 70.8 mm, LY30: -3.3% - 4.0% and CI: -3.8 - 2.9. Overall, 24.1% (33/137) of the volunteers had at least one abnormal parameter while 7.3% (10/137) would have been considered coagulopathy had the manufacturer's reference values been used, resulting in a test specificity of 76.0%. As compared with the western ethnicity (the manufacturer's reference values), Chinese healthy volunteers were associated with lower fibrinogen functions. There were significantly different in R, K, α-Angle, MA and CI between men and women groups (all P < 0.01).CONCLUSION:This study supports the manufacturer's recommendation that each institute should determine its own normal reference values.
