Thromboprophylaxie chez l'obèse en chirurgie bariatrique et non bariatrique

The number of morbid obese patients scheduled for bariatric surgery and other surgical procedures is increasing. Obesity and bariatric surgery are both risk factors of thombo-embolic events. The guidelines of the French national society of anesthesiology and intensive care advocate the use of low-molecular-weight heparin twice a day with increased doses not in excess to 10,000 UI·j−1 in combination with intermittent pneumatic compression. Due to a potential risk of bleeding a protocol including a single administration per day is currently evaluated.
