Objective To investigate the compliance status of intermittent pneumatic compression device (IPCD) in patients after lumbar surgery, and to analyze the reasons and influencing factors affecting compliance. Methods The continuous enrollment method was used to select patients who underwent posterior decompression for lumbar degenerative diseases in the orthopedic department of Peking Union Medical College Hospital between December 2022 and June 2023. The general information of patients and their compliance with IPCD were collected, and the reasons that affected compliance were analyzed. ResultsA total of 46 patients were included. The overall proportion of patients with good compliance was relatively low, and their compliance was poor. On the first and second day after surgery, the daytime compliance was relatively good (the proportion range of excellent compliance was 39%-52%); the compliance at night was significantly lower than that during the daytime (the proportion range of excellent compliance was 21%-26%); after 3 days of surgery, the patients’ compliance significantly decreased. A total of 460 time periods were observed and 195 reasons for not using IPCD were collected. The main reasons were physical discomfort caused by the device, inconvenience during bedside activities, and little significance to the patient. The compliance of female patients was better than that of males (P<0.05). Patients with education level of primary school and below had the highest compliance, while patients with high school and above had the lowest compliance (P<0.05). There was no statistically significant difference in compliance among patients of different age groups (P>0.05). Conclusions The overall compliance of patients with IPCD after lumbar surgery is poor, which is an urgent clinical problem, and the adaptability and cognitive level of patients to the device are the main factors affecting compliance. In clinical nursing work, men and patients with higher education level should be strengthened.
Objective To summarize the general situation of perioperative venous thromboembolism (VTE) and summarize the perioperative antithrombotic strategies. Methods Domestic and international literatures and guidelines on antithrombotic therapy were collect and reviewed. Results VTE was common during the perioperative period. Reasonable assessment of each patient’s condition during the perioperative period, as well as reasonable use of anticoagulant, antiplatelet drugs, and hemostatic agents could reduce the incidence of VTE events during the perioperative period. Conclusions Clinicians need to properly assess the timing of the usage and discontinuation of antithrombotic drugs, weigh the risk of thrombosis and bleeding, develop a rational and scientific antithrombotic strategy based on the specific circumstances of each patient. Simultaneously, hemostatic agents need to be prescribed perioperatively to reduce the incidence of thromboembolic complications.
Objective To study the correlation of preoperative hemoglobin amount with venous thromboembolism (VTE) after surgical treatment of bronchiectasis and the clinical significance. Methods A retrospective study was performed on patients with bronchiectasis who underwent surgical treatment in our center from June 2017 to November 2021. The differences in blood parameters between the VTE patients and non-VTE patients were compared. The relationship between preoperative hemoglobin and VTE was confirmed by quartile grouping and receiver operating characteristic (ROC) curve. Results A total of 122 patients were enrolled, including 50 males and 72 females, with a mean age of 52.52±12.29 years. The overall incidence of VTE after bronchiectasis was 9.02% (11/122). Preoperative hemoglobin amount (OR=0.923, 95%CI 0.870-0.980, P=0.008) and D-dimer amount (OR=1.734, 95%CI 1.087-2.766, P=0.021) were independent influencing factors for VTE after bronchiectasis. The incidence of VTE after bronchiectasis decreased gradually with the increase of preoperative hemoglobin amount. The area under the ROC curve (AUC) of postoperative D-dimer alone was 0.757, whereas the AUC of postoperative D-dimer combined with preoperative hemoglobin amount was 0.878. Conclusion Low preoperative hemoglobin is an independent risk factor for postoperative VTE. Postoperative D-dimer combined with preoperative hemoglobin amount has a better predictive performance compared with postoperative D-dimer alone for postoperative VTE.
Objective To explore the correlation between risk factors in respiratory department patients and the occurrence of venous thromboembolism (VTE), and to evaluate the optimization of the Padua score for predicting VTE occurrence in hospitalized respiratory patients based on these correlations. The effectiveness of the modified assessment model for VTE prediction was also validated. Methods A retrospective study was conducted, involving 51 VTE patients who were hospitalized in the Respiratory Department of Huaian First People’s Hospital from March 2019 to July 2023. These patients were compared with 1,600 non-VTE patients who were discharged during the same period. Clinical data, including medical history and laboratory test results, were retrospectively collected from both groups. The correlation between clinical data and VTE occurrence was analyzed, and highly relevant risk factors were incorporated into the Padua score. The modified Padua risk assessment model was applied to all patients and validated in a validation group. The scores from both the original and modified risk assessment models were compared to evaluate the effectiveness of the modified Padua score. Results Rank sum tests showed significant differences in basic information, such as age, BMI, and length of hospital stay, as well as laboratory tests including mean corpuscular volume, procalcitonin, albumin, alanine aminotransferase, aspartate aminotransferase, urea, and D-dimer (P<0.05). Univariate and multivariate logistic regression analyses revealed that newly identified high-risk factors for VTE included hypoalbuminemia (OR=2.972), blood transfusion (OR=47.035), and mechanical ventilation (OR=6.782) (P<0.05). Receiver operating characteristic curve analysis showed that the sensitivity and specificity of the modified Padua score were higher than those of the original version. The area under the curve (AUC) difference was 0.058, with a Z-test value of 2.442, showing statistical significance (P<0.05). Conclusions The modified Padua score demonstrated superior predictive ability for VTE in hospitalized respiratory patients compared to the original Padua score.
ObjectiveTo investigate association between the nutrition-related indicators and the recurrence of venous thromboembolism (VTE). MethodsThe clinical data from the patients with VTE receiving 3 or 6 months of anticoagulation therapy at the West China Hospital of Sichuan University, from January 2020 to October 2022, were retrospective analyzed. The multivariate logistic regression analysis was used to assess the association between the nutrition-related indicators such as albumin to fibrinogen ratio (AFR) and prognostic nutrition index (PNI) and VTE recurrence. The test level was set as α=0.05. ResultsA total of 141 patients with VTE were enrolled, of whom 12 (8.5%) experienced recurrence within 2 years. The multivariate logistic regression analysis identified several risk factors for recurrence, including diabetes [β=–3.368, OR (95%CI)=0.034 (0.001, 0.920), P=0.044], pulmonary embolism [β=–0.454, OR (95%CI)=0.635 (0.423, 0.954), P=0.029], and decreased AFR [β=–0.454, OR (95%CI)=0.635 (0.423, 0.954), P=0.029], but it was not found that the PNI was associated with VTE recurrence [β=–0.153, OR (95%CI)=0.858 (0.722, 1.020), P=0.083]. ConclusionThe findings of this study indicate that close monitoring for recurrent VTE is warranted in patients with diabetes mellitus, pulmonary embolism, and decreased AFR receiving anticoagulation therapy.
Objective To investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital to enrich the epidemiological data of chronic thromboembolic pulmonary hypertension (CTEPH) in China.Methods We conducted a retrospective study to investigate the incidence and management of CTEPH in the Department of Pulmonary and Critical Care Medicine in Xijing Hospital from 2008 to 2012. Results The incidence of CTEPH was 5.24% . About 62.90% of venous thromboembolism/pulmonary embolism (VTE/PE) patients were unprovoked, and about 53.85% of CTEPH patients was unprovoked. About 38% of CTEPH patients had no history of VTE, and 62% of CTEPH patients had no history of acute pulmonary embolism. None of the CTEPH patients was treated by pulmonary thromboendarterctom (PTE) , and about 53.85% of patients were only given anticoagulant monotherapy. Conclusions The incidence of CTEPH is higher in our hospital than reported. This phenomenon may be related to the lack of awareness of risk factors of CTEPH and the insufficient thrombolytic and anticoagulant therapy to acute pulmonary embolism. It’s very urgent to standardize the diagnosis and management of CTEPH in pulmonologists.
ObjectiveTo explore the predictive value of the maximum amplitude (MA) in the thromboelastogram (TEG) in the occurrence of venous thromboembolism (VTE) in patients with lung cancer after surgery.MethodsForty-one lung cancer patients with postoperative VTE in our hospital from September 2018 to August 2020 were enrolled into a thrombosis group, including 25 males and 16 females, aged 72.17±10.08 years. The 87 lung cancer patients who underwent surgery during the same period but did not suffer postoperative VTE were enrolled into a control group, including 51 males and 36 females, aged 71.06±9.49 years. The MA of thrombus in the TEG before and after the operation was compared between the two groups, and logistic regression analysis was used to test the value of the MA of thrombus at each time point in the TEG to predict the occurrence of VTE in patients with lung cancer surgery. The receiver operating characteristic curve was drawn to test the effectiveness of the MA of thrombus at each time point in the TEG to predict the occurrence of VTE in patients with lung cancer.ResultsThe MA of thrombus in the two groups after operation was greater than that before operation, and the MA of thrombus in the TEG on the day 3 after operation in the two groups> day 1> day 5 (P<0.05). The logistic regression analysis showed that the MA of thrombus in the TEG increased, which had predictive value for the occurrence of VTE in patients with lung cancer after surgery; the MA of thrombus in the TEG at each postoperative point was used as the test variable. Taking the occurrence of VTE as a state variable, the area under the curve (AUC) of MA of thrombus in the TEG on the 1st postoperative day was 0.82, and its optimal threshold was 75.15 mm; on the 3rd postoperative day, AUC was 0.88, and its optimal threshold was 80.05 mm; on the 5th day afterwards, AUC was 0.78, and its optimal threshold was 66.30 mm.ConclusionThe MA of TEG has a high predictive power for the occurrence of VTE in lung cancer patients after surgery, which suggests that TEG dynamic monitoring should be performed before surgery for lung cancer patients, and a reasonable anticoagulation plan should be formulated accordingly to reduce the occurrence of VTE.
Objective To summarize the present research progress of venous thromboembolism in the elderly. Methods Reviewed the literatures in recent years about the epidemiology, risk factors, diagnosis, prevention, and prognosis of venous thromboembolism in the elderly. Results Venous thromboembolism was a more common cardiovascular system diseases for the elderly, the incidence was higher, but the elderly didn’t pay much attention on it. The clinical manifestations of venous thromboembolism in elderly were different from young people, and all kinds of inspection methods had advantages and disadvantages. It gave priority to anticoagulation therapy, but we should pay attention to the risk of bleeding. Conclusions High incidence of venous thromboembolism was observed in the elderly, and diagnostic measures for venous thromboembolism were various. In the process of treatment, classification, the pros and cons were especially needed to pay attention to, and its special researches were necessary.
ObjectiveTo summarize the clinical value of Caprini risk score (CRS) and D-dimer testing, both individually and in combination, for venous thromboembolism (VTE) risk stratification in patients undergoing laparoscopic surgery. MethodsThrough systematic literature review and analysis, we evaluated the advantages and limitations of these two tools in predicting VTE, with emphasis on their combined utility and respective detection characteristics. ResultsCRS demonstrated superior population stratification efficacy for initial VTE screening post-laparoscopy but showed limitations in assessing individual heterogeneity. D-dimer testing exhibited high sensitivity in detecting postoperative hypercoagulable states, yet its specificity was confounded by surgical stress-induced coagulation activation. Their integration established a multidimensional assessment system that significantly enhanced identification accuracy of high-risk VTE populations. ConclusionsThe combined application of CRS and D-dimer biomarkers optimizes postoperative VTE risk stratification management and provides evidence-based guidance for defining precise anticoagulation therapy timeframes. Future research should prioritize refinement of risk assessment tools to facilitate dynamic patient monitoring, thereby guiding targeted thromboprophylaxis and reducing occult VTE risk.
ObjectiveTo summarize the current research progress on the relationship between thyroid cancer and venous thromboembolism.MethodsRetrieved the literatures about risk factors associated with thyroid cancer and venous thromboembolism both at home and abroad in recent years and reviewed the literatures.ResultsThe incidence of venous thromboembolism in patients with thyroid cancer was not high, and there were few factors related to risk factors, it might be related to the age of patient and the time of diagnosis of thyroid cancer. In addition, various types of therapeutic drugs for thyroid cancer might lead to the occurrence of venous thromboembolism.ConclusionsThe study of thyroid cancer and venous thromboembolism related factors and prethrombotic state occurrence are necessary to reduce the incidence of venous thromboembolism in thyroid cancer and improve prognosis.
