Deep vein thrombosis( DVT ) is a blood clot that develops deep in the vein. It can be fatal when the clot moves to the lung.
People who require prolonged bed rest are vulnerable because of their lack of movement and blood circulation ,especially patients in intensive care and patient on catheters are at a serious risk for DVT. Recent studies have shown that in critically ill patients , a small pulmonary embolism, which might be of minimal clinical importance in less ill patients, might have severe or fatal consequence.
After surveying nearly 70 physicians, researchers suggest exploring the role of routine ultrasound screening for DVT at intensive care units.
