DVT and pulmonary embolism — and why nurses keep making you walk.
When you undergo surgery, your body naturally tries to stop bleeding by activating your clotting system. During your procedure and recovery, you are physically inactive for long periods. This lack of movement causes blood to pool in your lower legs. These stationary pools can form a deep vein thrombosis (DVT), which is a blood clot located in a deep vein.
The main risk of a DVT is that a piece of the clot can break off. It then travels through your bloodstream toward your lungs. This blockage is called a pulmonary embolism (PE). It restricts blood flow and oxygen to your lungs, which creates a life-threatening emergency.
Walking is the most effective way to prevent clots. When you use your calf muscles, they act as a pump to push blood back toward your heart. This movement prevents blood from stalling in your legs. We will get you out of bed shortly after surgery specifically to keep your circulation moving.
If you cannot walk immediately, we use mechanical and chemical support. We may apply sequential compression devices, which are sleeves that squeeze your legs to stimulate flow. Your doctor may also prescribe anticoagulants, commonly known as blood thinners. These medications slow your body's ability to create new clots while you recover.
Watch for sudden swelling, redness, or tenderness in your lower legs, as these are signs of a potential DVT. If you experience shortness of breath or sharp chest pain, tell a nurse or doctor immediately. Do not ignore these symptoms, even if you feel like you are being a bother. Early detection significantly changes the outcome for your recovery.
