Intensive care patients have an increased risk of venous thromboembolic events (deep vein thrombosis (DVT) and pulmonary embolism (PE)) due to the presence of general risk factors for thrombosis (age, immobilization, obesity, prothrombotic history, etc.), but also risk factors specifically related to their stay in intensive care (sepsis, vasopressors, organ failure, mechanical ventilation, sedation, renal failure, central venous catheters). In addition, these same patients also have an increased risk of hemorrhagic events, mainly associated with coagulation disorders and thrombocytopenia. Given this increased risk of thrombosis, it is recommended that heparin thromboprophylaxis be used in intensive care patients in the absence of contraindications. In current practice, when faced with a patient with impaired renal function, there is significant heterogeneity in the prescription of thromboprophylaxis between centers and intensive care physicians: some will use enoxaparin, dalteparin, or tinzaparin regardless of renal function, while others will use subcutaneous calciparin or IVSE UFH. The PANTHER study is a prospective, multicenter, observational study that aims to evaluate the safety and efficacy of heparin thromboprophylaxis in critically ill patients with renal failure. The goal is to assess whether there is a difference in bleeding risk and thromboprophylaxis efficacy depending on the molecule used.
