BACKGROUND
The heparin regimen providing anticoagulation during cardiopulmonary bypass (CPB) is usually adapted to total body weight (TBW), but may be inaccurate in obese patients in whom TBW exceeds their ideal body weight.
OBJECTIVE
The objective is to compare the effects of heparin injection
BACKGROUND
Anticoagulation during cardiopulmonary bypass (CPB) is usually adapted to total body weight (TBW). This may be inaccurate in obese patients and lead to heparin overdose with a risk of bleeding.
OBJECTIVE
To validate the efficacy and safety of an adjusted calculation model of heparin
OBJECTIVE
Enhancement of lipoprotein lipase (LPL) activity through drug administration has been shown to increase pre-heparin serum LPL concentrations; however, pre-heparin serum LPL responses to exercise training have not been determined. The present study was undertaken to investigate the effects
OBJECTIVE
To report the use of subcutaneous lepirudin in an obese patient with heparin resistance.
METHODS
A 34-year-old morbidly obese male (weight 145 kg) presented with hypoxia on postoperative day 1 following a sigmoid colectomy. A continuous unfractionated heparin infusion was started for a
Background The effect of obesity on the pharmacokinetics and pharmacodynamics of unfractionated heparin is not clearly understood, therefore to reduce the risk of bleeding, maximal dose (capped) nomograms are often used. This can lead to inadequate anticoagulation and increased mortality and
Venous thromboembolism is a cause of morbidity and mortality in hospitalized patients, and morbid obesity increases this risk. Various prophylaxis dosing strategies have been investigated. However, it is unclear if high-fixed dose enoxaparin or high-fixed dose unfractionated heparin Timing and dosing of chemical venous thromboembolism (VTE) prophylaxis in brain injury is controversial. Risk of bleeding while using high dose unfractionated heparin (UFH) in overweight patients to prevent VTE is also unknown. The purpose of this study was to describe the use of subcutaneous
To determine the safety and efficacy of high-dose subcutaneous unfractionated heparin (UFH) for prevention of venous thromboembolism (VTE) in overweight and obese patients.
Single-center retrospective observational cohort study.

A 32-year-old, morbidly obese African-American woman developed bilateral pulmonary emboli 12 days after undergoing Roux-en-Y gastric bypass surgery. Three days later, after receiving heparin and warfarin, she developed heparin-induced thrombocytopenia type II (HIT-II). An argatroban
It has been suggested that heparin and its analogues may have a suppressive effect on the immune response by interfering with T-lymphocyte heparinase activity, thus altering the ability of T-lymphocytes to penetrate the extracellular matrix and migrate to target tissues. We have investigated whether
BACKGROUND
Most literature available for unfractionated heparin (UFH) supports the use of actual body weight for dosing all patients, yet a small proportion of the patients in these studies were morbidly obese. The most appropriate dosing strategy for therapeutic UFH in this patient population is
BACKGROUND
Obesity is endemic in the United States and obese patients are at increased risk of thromboembolism but little data are available for dosing unfractionated heparin (UFH). We evaluated the relationship between obesity and UFH efficacy during critical illness by examining UFH infusions in
BACKGROUND
Despite large interpatient variability in dose response, heparin is utilized for treatment of venous thromboembolism (VTE). Current data on the optimal heparin dosing in obese patients are conflicting.
OBJECTIVE
The objective was to evaluate the time and dose required to achieve a
BACKGROUND
Confusion exists when dosing heparin using a weight-based nomogram in the obese population. At 2 affiliated community teaching hospitals, we compared the activated partial thromboplastin time (aPTT) values in morbidly obese and nonmorbidly obese patients using a standardized nomogram and
There is limited guidance on intravenous dosing of unfractionated heparin in obese patients. The purpose of this study was to determine the efficacy and safety of a standard unfractionated heparin (UFH) protocol in obese patients based on total body weight (TBW) or adjusted body weight (ABW) to
