enoxaparin prophylaxis dose in obese patients

Methods: In morbidly obese, medically-ill patients, use of weight-based enoxaparin dosed at 0.5 mg/kg once daily is feasible and results in peak anti-Xa levels within or near recommended range for thromboprophylaxis, without any evidence of excessive anti-Xa activity. The study included 36 consecutive patients (mean age 60 years) (range 13-87) with recent deep vein thrombosis (less than 5 days) documented by venography. In the class III obese, the WOMAC score was significantly higher than the nonobese (58.1 vs. 44.3, p < 0.001 preoperatively; 15.7 vs. 8.1, p = 0.005 at 1 year) and KSS was significantly lower (83.5 vs. 96.5, p = 0.049 preoperatively; 172 vs. 185; p = 0.003 at 1 year). In conclusion, high-dose thromboprophylaxis nearly halves the rate of VTE in morbidly obese inpatients. Although practices are expected to differ between hospitals, the findings of this study have highlighted conservative dosing in the absence of prescribing guidelines for the population of concern. High-dose thromboprophylaxis did not increase bleeding (OR 0.84, 95% CI 0.66-1.07, p = 0.15). Bilateral TKA and failure to ambulate by the second day after surgery were significant risk factors. For optimal VTE prevention, all patients admitted to hospital should have early and formal assessments of: (i) their intrinsic VTE risk and the risks related to their medical conditions; (ii) the added VTE risks resulting from surgery or trauma; (iii) bleeding risks that would contraindicate pharmacological prophylaxis; (iv) any contraindications to mechanical prophylaxis, culminating in (v) a decision about prophylaxis (pharmacological and/or mechanical, or none). venous thromboembolism. Factors significantly associated with VTE were bilateral simultaneous TKA (odds ratio [OR] = 4.2; 95% confidence interval [CI]: 1.9–9.1), receipt of FDA-approved pharmacological prophylaxis (OR = 0.5; 95% CI: 0.3–0.8), and ambulation by postoperative day 2 (OR = 0.3; 95% CI: 0.1–0.9). enoxaparin, 1.5 mg/kg; oral tenoxicam; or placebo, once daily for 8 to 12 days. In the class II obese, as compared to the nonobese, there was no difference in any parameter preoperatively and 3 months postoperatively. School of Pharmacy and Biomedical Sciences, Curtin University, Perth, Australia. The efficacy and safety of antithrombotic treatment in patients with superficial vein thrombosis remain to be established in adequately designed trials. This article focuses on the use of fondaparinux as a prophylactic agent against VTE in patients undergoing major orthopedic and abdominal surgery along with high risk medical patients; it will also discuss the recent promising data on its use to treat active DVT and PE. It was the objective of this study to quantify the efficacy and safety of high-dose thromboprophylaxis with heparin or enoxaparin in inpatients with weight > 100 kilograms (kg) within the BJC HealthCare system. Fractures, rheumatoid arthritis, and revisions were excluded. Enoxaparin is a low molecular weight heparin used for prophylaxis and treatment of venous thromboembolism. These insights inform the clinical setting in the determination of local prescribing guidelines. Patients at extremes of weight should have the dose of enoxaparin adjusted and anticoagulation should be monitored using the low molecular weight heparin assay. Longer-term studies are needed to determine if these results are maintained. The 9th edition of the American College of Chest Physicians (ACCP) guidelines on antithrombotic therapy and prevention, includes relevant changes compared to previous versions. Our institution developed an inpatient protocol with reduced enoxaparin doses (0.75 mg/kg/dose based on actual body weight) for patients with a weight >200 kg or BMI > 40 kg/m(2). Setting: Percentage of appropriate anti-Xa levels at first dose differed 0% vs. 30.8% (Group 1 vs. Group 2; p = 0.01) and at third dose 9.1% vs. 41.7% (Group 1 vs. Group 2; p = 0.155). Comparison of the present findings with a review of prescribing patterns after the implementation of new guidelines may provide valuable information regarding the uptake and clinical effect of the guidelines. The class III obese would have poorer functional scores and lesser knee flexion postoperatively compared to the nonobese. We queried a combined Humana and Medicare database between 2007 and Quarter 1 of 2016, and identified all primary TKAs performed using ICD-9 and Current Procedural Terminology codes. However, most of the data demonstrating the efficacy and safety of extended thromboprophylaxis and short term thromboprophylaxis is from clinical trials done in the West. high-dose enoxaparin as its intervention (12,16-18). Fisher's exact test and t test were used for the statistical analysis. The only recommendation that has been upgraded is to extend prophylaxis with low molecular weight heparins (LMWH) for four weeks after abdominal or pelvic cancer surgery. Objective: When venous thromboembolism incidence was adjusted for age and sex, no statistically significant differences were found between overweight (OR = 0.685; 95% CI 0.115-4.095), obese (OR = 0.797; 95% CI 0.353-1.796), and combined overweight and obese (OR = 0.656; 95% CI 0.154-2.799) groups compared to patients with normal body weight. VTE prevention includes deep venous thrombosis and pulmonary embolism. This can lead to undertreatment, and increased monitoring is recommended. Rivaroxaban has the potential to replace standard therapy, usually parenteral low molecular weight heparin overlapping with and followed by a vitamin K antagonist, for the treatment of acute symptomatic DVT and the secondary prevention of VTE. Inpatient: 1 mg/kg subcutaneously every 12 hours or 1.5 mg/kg subcutaneously once a day at the same time every day. Suboptimal dosing, delayed initiation, and overreliance on mechanical methods may also limit the effectiveness of thromboprophylaxis. India, the data of the incidence of venous thromboembolism (VTE) following THA/TKA has been conflicting and the duration has not been clearly defined. Round all enoxaparin doses to the nearest injection syringe availability. Key search terms (in UK and US spelling) included orthopaedics, low-molecular-weight heparin, enoxaparin, venous thromboembolism prophylaxis, weight, obese, morbid obesity. Three wards (Orthopaedic Surgery, General Medicine and the State Major Trauma Unit) were selected to represent surgical, medical and critical inpatients. Otolaryngologists should consider an individualized and risk-stratified plan for perioperative thromboprophylaxis in every patient. Obese patients are at higher risk for thromboembolism. The Caprini system allows effective individualized risk stratification for VTE prevention in otolaryngology. Among the 3,928 morbidly obese inpatients (weight > 100 kg and body mass index [BMI] ≥ 40 kg/m2), high-dose thromboprophylaxis approximately halved the odds of symptomatic VTE (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.27-1.00; p = 0.050). The average daily dose of enoxaparin was 67 mg (+/-12). Data synthesis: Conclusions: Non-obese patients receiving enoxaparin 40mg daily receive a weight based dose of 0.4-0.8 mg/kg. However, measurement of weight is challenging in immobile patients. Ten deaths (7%) occurred in the overweight group, 45 (15%) in the obese class I group, 38 (12%) in the obese class II group, and in 53(8%) the obese class III group (p=0.067). 11858). A total of 223 patients mechanically ventilated for acute, Unfractionated heparin is effective in the treatment of deep venous thrombosis and pulmonary embolism but may lead to significant side-effects (bleeding complications and thrombocytopenia). The median length of hospital stay was 5 (interquartile range 3-9) days (p=0.122) for all patients. We explored the associations between the type of thromboprophylaxis, obesity, time of mobilization, and undergoing bilateral TKA on development of symptomatic venous thromboembolism (VTE) after TKA. Four (including one of the four obese patients) received 20 mg enoxaparin daily, as per guidelines for non‐obese patients; the remaining 11 received the standard 40‐mg daily dose.2. Both are administered by the oral route, once-daily fixed dose and without the need to monitor the anticoagulant effect. Study selection and data extraction: In addition, the Thromboembolism-Prevention in Cardiopulmonary Diseases with Enoxaparin (THE-PRINCE) trial showed that enoxaparin treatment was as effective as UFH. Emerging antithrombotic agents for thromboprophylaxis, clinical potential and patient considerations. In conclusion, subcutaneous administration of enoxaparin proved to be an effective antithrombotic therapy. It includes dosing recommendations to guide clinicians caring for these patient populations. In this prospective, multi-center trial, enoxaparin … A four-way chi-squared test was used to determine statistical significance. Low molecular weight heparin fragments have been shown to be as effective as unfractionated heparins during prophylaxis with a once-daily injection regimen. All patients who had any form of antiplatelet or anticoagulation prescribed within 1 year before TKA were excluded from our study cohort. Duration of therapy: At least 5 days and until a therapeutic oral anticoagulant effect has been achieved (INR 2 to 3). The authors acknowledge RPH Medical Records staff and Michael Leahy for assistance with data acquisition. As the use of rivaroxaban for DVT treatment increases in clinical practice, a fundamental understanding of its clinical benefits in everyday patient care is essential. In Group 1, anti-Xa levels were 0.06 and 0.08 units/mL after the first and third doses, respectively. The purpose of this study was to compare reverse total shoulder arthroplasty (RTSA) outcomes in normal weight, overweight, and obese patients. Two hundred thirty-seven cancer patients with deep venous thrombosis (DVT) were initially treated with fondaparinux or enoxaparin. While several escalated doses have been shown to result in more frequent attainment of target anti-factor Xa levels than standard doses, few studies compare escalated doses to each other. 105,189 participants were followed up for a median (inter-quartile range) of 2.6 (1.3-4.2) years. Postoperatively, there was no significant difference in absolute values or degree of improvement of rotation between groups. Patients with a Caprini score ≤4 should receive mechanical prophylaxis alone. Product labeling on use in obese patients: Enoxaparin* Use standard treatment dosing (ie, 1 mg/kg every 12 hours based on ABW). Patients without a baseline weight, serum creatinine, a history of heparin-induced thrombocytopenia, or currently pregnant patients … Literature is inconclusive regarding fixed or weight‐based dose adjustment of enoxaparin to prevent VTE in overweight and obese patients. Analysis revealed only two cases of enoxaparin dose increases among the 92 obese patients, and little individualised dosing overall. On the other hand, the standard treatment dose of enoxaparin is 1 mg/kg twice daily or 1.5 mg/kg daily. Please check your email for instructions on resetting your password. Data show the number of subjects in each group. A search using PubMed was conducted (1995 to January 2018) using the following key words: enoxaparin, body weight, AND thromboprophylaxis, or AND treatment. N/A, serum creatinine was not measured. For these reasons, he was treated with enoxaparin 40 mg once daily subcutaneously. The efficacy was assessed by the evolution of Arnesen venographic score. Conclusions: The class II obese can expect comparable early functional recovery as the nonobese but their late function may be lesser. Introduction. This study suggests the need for hospital‐wide audit of VTE prophylaxis to establish a longitudinal database or point‐in‐time analyses, including clinical outcomes for patients, followed by derivation, implementation and monitoring of a local prescribing guideline that attempts to draw together the best‐available evidence. enoxaparin. Of these, 39.5% (343/869) received VTE prophylaxis with enoxaparin, 38% (331/869) received unfractionated heparin, 1.5% (13/869) received therapeutic anticoagulation and 21% (182/869) did not receive prophylaxis. You can request the full-text of this article directly from the authors on ResearchGate. Several investigators have analyzed adjusted-dose VTE prophylaxis with LMWHs in obese patients by evaluating rates of thromboembolic events and pharmacodynamic parameters. The present methods may be used in other jurisdictions facing a similar lack of clarity in their prescribing guidelines. Possible related subheadings, such as bone, fractures, anticoagulants, overweight, body mass index, deep vein thrombosis, pulmonary embolism, were also included in the database search to optimize the search strategies. The biological properties of hirudin combined with its ready availability as recombinant forms make this drug well-suited for use as an anticoagulant agent. This audit provides an insight into the complexity and uncertainty of dose adjustment of prophylactic enoxaparin, with specific focus on overweight/obesity, and considering renal function. Objective: To review the literature on both thromboprophylaxis and treatment of venous thromboembolism (VTE) with enoxaparin in low- and high-body-weight patients and to make dosing and monitoring recommendations in these patient populations.Data Sources: A search using PubMed was conducted (1995 to January 2018) using the following key words: enoxaparin, body weight, AND … Like enoxaparin, the prophylactic dose should be increased in morbid obesity, for example 5000 units three times a day or 7500 units twice daily. In the prospective arm, only 1 patient developed symptomatic PTE compared to 26 (3.27%) cases of VTE (20 cases of PTE and 6 cases of DVT) in the retrospective group. We compared the efficacy and safety of nadroparin calcium (nadroparin) with placebo in medical patients at high risk of DVT. Low-molecular-weight heparin (LMWH) is a class of drugs commonly used as antithrombotics in surgery and in case of prolonged bed rest and hypomobility. However, morbidly obese patients were under-represented in these trials and using fixed-dose enoxaparin in obese patients may be inadequate. We included, Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism, poses a substantial clinical risk, and the incidence of these thrombotic-related diseases remains high. Given that over 50% of patients were overweight or obese with normal renal function, this finding suggests underdosing Obesity increases the risk for venous thromboembolism (VTE), but whether high-dose thromboprophylaxis is safe and effective in morbidly obese inpatients is unknown.
