Most data in this area are from studies that utilize pharmacokinetic variables, surrogate markers for efficacy or physicochemical characteristics. So 40 mg enoxaparin daily became entrenched as a standard treatment in many medical ICUs. Lean body weight appears to be the best representation of fat-free mass [ 5 ].

Data synthesis: Optimal enoxaparin dosing strategies for VTE prophylaxis and treatment for patients at extremes of weight have not yet been elucidated by clinical trials; however, data suggest that standard dosing regimens may not be appropriate in these patients. 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. Relevance to Patient Care and Clinical Practice: This review provides a thorough discussion on both thromboprophylaxis and treatment of VTE with enoxaparin in low- and high-body-weight patients. Conclusions: In obese trauma patients, weight-based enoxaparin is an efficacious regimen that provides adequate VTE prophylaxis, as measured by anti-Xa levels, and appears to be safe without bleeding complications.

Enoxaparin prophylaxis obesity Clinical Trial. Anticoagulants for venous thromboembolism prophylaxis, on the other hand, require an individualized approach where higher doses are necessary. Used with permission. Cimetidine clearance in the obese. This is a descriptive study evaluating the feasibility and predictability of administering weight-adjusted enoxaparin 0. Additionally, corticosteroids easily pass through cell membranes to bind to cytosolic glucocorticoid receptors that are present in almost all body cells, so the relationship between pharmacokinetic and pharmacodynamics effects is complex [ 35 ]. The primary outcome was achievement of target anti-Xa level 0.

This is problematic because the use of an incorrect weight metric, for weight-based dosing, could lead to treatment failure in the event of subtherapeutic levels or drug toxicity caused by supratherapeutic levels Fig. However, I am hesitant to extrapolate pharmacokinetics to clinical outcome for two reasons. The sensitivity of this assay is 0. The highest quality evidence might be the comparison of 40 mg enoxaparin daily versus 2. Study Description.

Designing dosing regimens in the critically ill obese patient requires a detailed understanding of the physicochemistry of the medication, enoxaparin prophylaxis obesity the impact obesity has coupled with critical illness on physiology and drug pharmacokinetics [ 6 ]. Studies which have measured and targeted trough levels were able to achieve trough levels only with a twice-daily dosing regimen. Baseline clinical and demographic information will be obtained and recorded on standard case reporting forms, CRF see Appendix B.

The incidence of VTE and bleeding complications were recorded. Conclusions: In obese trauma patients, weight-based enoxaparin is an efficacious regimen that provides adequate VTE prophylaxis, as measured enoxaparin prophylaxis obesity anti-Xa levels, and appears to be safe without bleeding complications. Publication types Comparative Study. Data synthesis: Optimal enoxaparin dosing strategies for VTE prophylaxis and treatment for patients at extremes of weight have not yet been elucidated by clinical trials; however, data suggest that standard dosing regimens may not be appropriate in these patients. Conclusions: Patients at extremes of weight require special consideration to determine appropriate enoxaparin doses. No bleeding complications occurred, and no symptomatic pulmonary emboli were identified.

One retrospective, before-after study compared Enoxaparin prophylaxis obesity rates using two enoxaparin dosing regimens 30 mg or 40 mg subcutaneous twice daily in a cohort of bariatric surgical patients [ 67 ]. Author Recent Posts. Abstract Medications used for supportive care or prophylaxis constitute a significant portion of drug utilization in the intensive care unit. Five milliliters of blood will be drawn. A retrospective cohort study of adult medical and surgical inpatients weighing at least lb compared 2, patients receiving sub-cutaneous high-dose heparin 7, units three times per day or enoxaparin 40 units two times per day with 6, patients receiving standard-dose heparin 5, units two or three times per day or enoxaparin 40 units per day for VTE prophylaxis and bleeding.

Both authors read and approved the final manuscript. Heparin dosing for venous thromboembolism prophylaxis in obese hospitalized patients: an observational study. However, available evidence suggests that this is a poor strategy. If the 12h anti-Xa level is obtained and is less than 0. Margaret, Pittsburgh, Pennsylvania. Finally, one prospective trial evaluated a BMI-stratified dosing approach in a cohort of bariatric surgery patients [ 60 ]. Download citation.
