ABSTRACT
【Objective】 To establish a blood transfusion outcome prediction model for comprehensivel evaluation of coagulation function of patients with upper gastrointestinal bleeding by thrombelastogram (TEG) and blood coagulation indicators. 【Methods】 The data of 101 patients with upper gastrointestinal hemorrhage, admitted to the Department of Gastroenterology of Zhejiang Provincial People′s Hospital and its Chun′an Branch from June 2018 to June 2021, were collected through Tongshuo blood transfusion management system and His system. Those patients were divided into blood transfusion group (n=56) and non-transfusion group (n=45), and into cirrhosis group (n=74) and non-cirrhosis group (n=27), and 40 patients, with non-upper gastrointestinal bleeding, were enrolled as the control. The results of TEG indicators (R, K, α, MA), coagulation function (PT, INR, APTT, TT, Fib), blood routine (Hb, Plt, WBC, NEUT%) and biochemical detection(Alb, SCr, ALT, AST, GGT) before transfusion were compared between groups and the correlation between TEG indicators and traditional coagulation parameters was analyzed. Single-factor and multi-factor analysis were used to screen blood transfusion-related factors to establish a predictive model. 【Results】 The comparisons of paremeters between transfusion and non-transfusion group were as follows, K (min), α (°), and MA (mm) was 3.86±3.12 vs 2.50±1.47, 54.00±14.08 vs 61.05±10.88, and 51.12±13.37 vs 58.26±11.08, respectively (P<0.01); PT (s) and Fib (g) was 16.36±7.45 vs 13.44±1.50 and 1.59±0.87 vs 2.35±1.09 (P<0.01); NEUT% and Hb (g/L) was 0.75 ±0.13 vs 0.66±0.15 and 68.04±14.49 vs 100.73±22.92 (P<0.01); Alb (g/L) and SCr (nmol/L) was 29.73±6.08 vs 33.73±7.19 and 99.50±53.55 vs 76.25±19.28 (P<0.01). Correlation analysis showed that APTT was positively correlated with R and K values, and negatively correlated with α and MA. Fib was negatively correlated with K values, and positively correlated with α and MA. Plt was negatively correlated with K values, and positively correlated with α and MA (P<0.01). Eight pre-transfusion indicators as K, MA, PT, Fib, NEUT%, Hb, Alb, and SCr were subjected to Logistic regression to establish a blood transfusion prediction model. The optimal ROC curve of blood transfusion threshold (blood transfusion predictive value of patients), sensitivity, specificity and AUC were 0.448, 92.9%, 88.9%, and 0.969, respectively. 【Conclusion】 The establishment of Logistic regression model by integrating detection indicators of TEG, coagulation function, blood routine and biochemistry in patients with upper gastrointestinal bleeding have showed significant correlation with blood transfusion prediction, and good clinical practicability.
ABSTRACT
Objective To analyze and evaluate the current progress of blood transfusion department establishment and clinical blood transfusion management in Hangzhou,China.Methods Questionnaires were sent to 35 medical institutions to gather information regarding blood transfusion department establishment and clinical blood transfusion management in the provincial,municipal and county tier hospitals.The investigated criteria covered the establishment of the hospital blood transfusion management committee,the utilization of software and hardware of the transfusion department,the compatibility status of various software systems in use and performance evaluation of these systems in clinical applications,etc.In addition,tests were also conducted on members of the blood transfusion departments to confirm whether they are properly trained and present adequated knowledge of clinical blood applications Results were then collected for statistical and descriptive analyses.Results The results out of the 35 hospitals surveyed presented no obvious statistical significance.Nevertheless,the average score of these hospitals in different segments helped us to reach the following conclusions:1,Triple-A hospitals scored the highest average score for patient clinical status evaluation pre-transfusion;2.Double-B hospitals came first when it comes to patient clinical status evaluation post transfusion;3.Triple-B hospitals possessed the most thorough clinical records for transfusion treatment.A total of 350 papers were issued and 350 papers were collected,with 327 out of the 350 considered valid.As for the test results regarding the departments members,triple-A,triple-B and double-A hospitals scored significantly higher than double-B and unranked hospitals.(P＜0.05);.350 clinical transfusion records were also collected and 247 of which are considered valid.It appears there are numerous difference in Hb indexes among the tested hospitals and even the departments of internal medicine and surgical presented different takes on the subject as well.Conclusion The clinical blood transfusion management in Zhejiang province and the establishment of blood transfusion departments still need to be improved.A plan to manage clinical blood use need to be carried out ASAP,which would specify evaluation references,standardize personnel training and tech investments.Ultimately,we hope such actions would help to further regulate the clinical blood use in the region.
ABSTRACT
Objective To investigate the effectiveness and safety of dexmedetomidine combining with sufentanyl in controlling PCIA after laryngeal carcinoma surgery. Methods One hundred laryngeal carcinoma patients (ASAⅠorⅡ) were randomly assigned into 2 groups (n = 50, in each group). Group SF: sufentanil 0.04 mg/(kg·h)+dolasetron 12.5 mg; Group DE: dexmedetomidine 0.1 mg/(kg·h) +sufentani 0.02 mg/(kg· h) +dolasetron 12.5 mg, in which all drugs were dissolved in 100 mL 0.9% normal saline. Parameters: Infusion speed 2 mL/h; PCIA dosage 0.5 mL each time; monitor time: 15 min. PCIA were administrated after anesthesia recovery; BP, HR, SpO2, RR, RPP, pain and sedation score, side effect formation rate at 4、12、24、48 h after surgery were also recorded. Results MAP, RPP and HR in group DE were significant decreased compared with group SF at each time point,(P 0.05); Ramsay calm scores in group DE were significant better than that in group SF at each time point after surgery (P < 0.05); Frequency of nausea,vomiting and chills in group DE were significant lower than those in group SF (P < 0.05). Conclusion Small dose dexmedetomidine combination with sufentanil administration in PCIA after laryngeal carcinoma surgery could acquire satisfied analgesic effect , also could eliminate the patient anxious mood , enhance the security in the perioperative period and improve the patients' satisfaction degree , whichis very suitable for multi mode analgesia acquirement.
ABSTRACT
Objective To investigate the effects of autologous blood withdrawal-reinfusion on the perioperative coagulation function in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB ) . Methods Eighty-four ASA physical status Ⅱ-Ⅳ patients ,without impairment of coagulation function ,scheduled for cardiac surgery with CPB ,were equally and randomly divided into 2 groups using a random number table :autologous blood withdrawal-reinfusion group (group ABWR , n= 44 ) and control group (group C , n= 40 ) . Decreased coagulation function was diagnosed based on the following two criteria :laboratory standard of decreased coagulation function and clinical signs .After anesthesia and before the beginning of operation (T1 ) ,at 5 min after heparin was reversed with protamine (T2 ) ,at the end of operation (T3 ) and at 24 h after the end of operation (T4 ) ,venous blood samples were obtained to measure the blood routine and parameters of coagulation function . Blood routine included the red blood cell (RBC ) , hemoglobin (Hb ) , hematocrit (Hct ) , platelet count , and plasma fibrinogen concentration (Fib) .The parameters of coagulation function included thrombelastography (TEG) variables and prothrombin time (PT ) ,activated partial thromboplastin time (APTT ) ,international normalized ratio (INR ) , and activated clotting time (ACT ) . The volume of intraoperative blood loss , amount of mediastinal drainage at 6 and 24 h after operation , consumption of tranexamic acid and heparin during operation , and consumption of fibrinogen after operation ,and requirement for transfusion of allogeneic RBCs ,fresh frozen plasma (FFP) and platelet during operation and within 24 h after operation were recorded .The development of decreased coagulation function during operation and within 24 h after operation .Results Compared with group C , perioperative consumption of allogeneic RBCs were decreased ,reaction time (R) measured by celite-activated TEG was increased at T3 (P 0.05 ) . Conclusion Autologous blood withdrawal-reinfusion provides similar effects on coagulation function with allogeneic blood transfusion ,and does not increase the development of decreased coagulation function in patients undergoing cardiac surgery with CPB .
