ObjectiveTo investigate the effects of intraoperative intermittent pneumatic compression (IPC) treatment on coagulation and fibrinolysis, lower extremity venous blood flow velocity, and deep venous thrombosis (DVT) in patients with gastric cancer (GC) after radical gastrectomy. MethodsThe patients with GC who underwent radical gastrectomy at Hebei Provincial People’s Hospital from July 2021 to July 2024 were retrospectively enrolled, then the patients were assigned into control group (the patients who did not receive intraoperative IPC) and study group (the patients who received intraoperative IPC), and the propensity score matching (PSM) method was used to conduct 1∶1 matching based on the basic characteristics such as age, gender, body mass index, comorbidities to ensure baseline comparability between the two groups. The incidences of postoperative DVT and lower extremity swelling, and coagulations [prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT)] and fibrinolysis [D-dimer (D-D), fibrinogen (FIB), and fibrin degradation products (FDP)], as well as lower extremity venous blood flow velocity were analyzed after PSM. The locally weighted regression was used to analyze the correlation between the coagulation and fibrinolytic functions indexes and the lower extremity venous blood flow velocity. ResultsA total of 120 patients were matched (60 cases per group). The baseline characteristics of both groups were comparable (P>0.05). The incidences of DVT on day 7 and lower extremity swelling on day 1, 3, and 7 after surgery in the study group were significantly lower than those in the control group (P<0.05). The results of repeated-measures analysis of variance showed that there were statistically significant differences in the inter-group, time-related, and group-by-time interaction effects of coagulation and fibrinolysis indexes as well as lower extrimety venous blood flow velocities (P<0.05). The impact of the time factor on coagulation and fibrinolysis indexes and lower extrimety venous blood flow velocities varied with intraoperative IPC intervention measures. After surgery, the PT, TT, APTT, and lower extrimety venous blood flow velocities in the study group first decreased and then increased as compared with those before surgery, and the decrease degree was smaller and the increase degree was larger than those in the control group. After surgery, the D-D, FIB, and FDP in the study group first increased and then decreased as compared with those before surgery, and the increase degree was smaller and the decrease degree was larger than those in the control group. Both PT and TT were significantly positively correlated with femoral vein blood flow velocity (r=0.21, P=0.042; r=0.22, P=0.040), and both also showed significant positive correlations with popliteal vein blood flow velocity (r=0.25, P＜0.001; r=0.20, P=0.032). APTT was only significantly positively correlated with popliteal vein blood flow velocity (r=0.33, P＜0.001). D-D was negatively correlated with the flow velocities of the femoral vein, external iliac vein, and popliteal vein (r=–0.23, P=0.012; r=–0.22, P=0.047; r=–0.37, P<0.001). Both FIB and FDP were negatively correlated with the flow velocity of the femoral vein (r=–0.23, P=0.036; r=–0.27, P=0.002). FIB was also negatively correlated with the flow velocity of the popliteal vein (r=–0.26, P=0.038), and FDP was negatively correlated with the flow velocity of the external iliac vein (r=–0.31, P<0.001). ConclusionBased on the results of this study, intraoperative IPC treatment could improve coagulation and fibrinolytic functions of patients with GC after surgery, and has a certain preventive effect on occurrence DVT of lower extremity.
ObjectiveTo evaluate the venous thromboembolism (VTE) risk and anticoagulant therapy in patients with coronavirus disease 2019 (COVID-19).MethodsThe patients with COVID-19 in Optics Valley Hospital of Wuhan Tongji Hospital from February 9, 2020 to March 29, 2020 were collected and analyzed. Padua scores were performed within 24 hours after admission. The relationship between Padua score, disease severity and 28 day prognosis was analyzed.ResultsCOVID-19 was diagnosed in 102 cases. The age, fibrinogen and mortality of the severe group were significantly higher than those of the common group. The Padua score of the severe group was higher than that of the common group, but there was no statistical difference. The platelet count in the critical group was significantly lower than that in the severe group, while the prothrombin time (PT), activated partial thromboplastin time (APTT), and D dimer were significantly higher than that in the severe group, and the Padua score, anticoagulation ratio, and mortality were significantly higher than those in the severe group. According to Padua score 4, it was divided into VTE high risk group (≥ 4 points) and VTE low risk group (<4 points). The mortality, APTT, D dimer and fibrinogen of high risk group were significantly higher than those of low risk group. In the high-risk group of VTE, the anticoagulation rate was significantly higher than that in the low-risk group of VTE, but it was still only 41.7%. The mortality of patients with anticoagulation was lower than that of patients without anticoagulation.ConclusionsSevere and critical novel coronavirus pneumonia patients have obvious coagulation dysfunction and high risk of VTE. Anticoagulant therapy may be associated with low mortality in patients with high risk of VTE, but the proportion of drug-induced anticoagulant intervention still needs to be improved.
肝臟移植作為終末期肝病的治療，自上個世紀80年代在歐美國家獲得公認以來，已在世界各國得到迅速開展。我國自90年代后期以來，在全國掀起了第二個肝移植的熱潮，迄今已完成1 000余例肝移植，在圍手術期處理、手術技術、介入放射、移植免疫、抗感染治療等各個方面均獲得豐富的經驗，我國肝移植的效果及長期生存率亦逐步趕上國際先進水平。總的來講，適合進行肝移植的病種可分為良性及惡性肝病，鑒于惡性肝病行肝移植后復發率高，長期生存率低，因而其作為肝移植的指征長期以來存在爭議，而良性終末期肝病則是肝移植的主要指征。我院自1999年2月以來連續施行肝移植114例，其中良性肝病為69例，占60.5%。本文僅針對良性肝病肝移植的一些特點談談我們的經驗和體會。
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.
目的 比較進展性慢性肝病及重癥肝炎患者原位肝移植(OLT)圍手術期凝血功能的變化。方法 回顧性分析我中心2004年1月至2005年12月期間行OLT治療進展性慢性肝病及重癥肝炎患者各37例的圍手術期血小板(PLT)、凝血酶原時間(PT)、活化部分凝血活酶時間(APTT)及纖維蛋白原(FIB)的變化。結果 2組患者除術前PT、APTT,術后第5 d PLT、FIB和術后第7 d FIB的差異有統計學意義外（plt;0.05），其余時段2組患者的PLT、PT、APTT及FIB 間差異均無統計學意義（Pgt;0.05）, 提示重癥肝炎患者凝血功能損害更為嚴重； OLT術后，2組患者的凝血功能均逐漸恢復正常, 但并非完全同步。結論 進展性慢性肝病與重癥肝炎患者OLT圍手術期凝血功能變化顯著，應注意監測及處理，但術后2組間各指標間比較差異并不明顯。
目的 分析反復發作的抗凝血類滅鼠藥所致獲得性凝血功能障礙的臨床特點，探討其診治方案。方法 對2009年3月－2010年12月收治的3例抗凝血類滅鼠藥所致獲得性凝血功能障礙患者的臨床表現、實驗室檢查和治療轉歸進行分析，并復習相關文獻。 結果 3例患者均以同時出現多部位出血為首發表現，經應用維生素K1、凝血酶原復合物、新鮮冰凍血漿、冷沉淀等治療，患者病情好轉，實驗室指標恢復正常。停藥（2、5周，3個月）后再次出現多部位出血，再給予維生素K1等治療，病情可緩解。 結論 維生素K1可作為首選的治療藥物，且對反復發作的患者同樣有效。為避免再發性出血，應維持治療至少3個月。
Objective To preliminarily summarize the diagnosis and treatment of coagulopathy in patient with severe hepatic cirrhosis who underwent orthotopic liver transplantation (OLT). Methods Preoperative coagulability, the replacement therapy by coagulation factors and platelet pre-and intraoperatively, intra-operative bleeding amount and blood transfusion amount and the relation to the postoperative course were analyzed retrospectively in 6 patients with severe hepatic cirrhosis who underwent OLT in the last year. Results All of the 6 patients had a Child-c preoperative hepatic function, 2 with prolongation of bleeding time. All of the 6 had a decrease of platelet count, with a mean platelet count of 25.3×１０９／Ｌ. Mean prolongation of prothrombin time was 10.7 seconds as compared with controls. Mean prolongation of activated partial thromboplastin time was 23.1 seconds as compared with controls. Mean fibrinogen was 1.5 g/L. Mean pre- and intra- operative transfusion of fresh frozen plasma was 788 ml, platelet 7.1×１０12， cryopreciptitate 5.5 units, fibrinogen 2.8 grams and lyophilized prothombin complex concentrate (LPCC) 1 700 units. The first 4 cases in the early period had a mean bleeding amount of 8 672.5 ml, with a mean transfusion of 9 215.0 ml. One of the 4 with the most massive intraoperative bleeding was complicated by severe internal milieu disturbance, DIC and fungus infection and died of the infection. Postoperatively the last 2 cases in the late period had a complete preoperative replacement of coagulation factors and platelet and had a only mean bleeding amount of 2 700 ml with a mean transfusion amount of 3 638 ml. Conclusion We initially consider that a preoperative complete replacement of coagulation factors and platelet according to the coagulability tests may lessen intraoperative bleeding and transfusion and make the patient an uneventful postoperative course.
