Blood clots are rarely dangerous on their own. As part of the body's natural healing mechanism, clots that have formed for whatever reason are usually dissolved (lysis) and reabsorbed by the body without danger or need for intervention.
They can be dangerous, however, when they form within arteries and veins and obstruct the normal flow of blood within the body. The patient who is bedridden after surgery is at greater risk for blood clotting due to slowed blood flow. (this is one of the reasons why they made you get up and walk far sooner than you wanted to!!)
Your nurses and doctors will be checking regularly for blood clots. Let them know immediately if you have any tenderness in your legs, especially the calves.
If a blood clot is suspected, tests will be performed to confirm the diagnosis and medications ("clot busters") will be started to help reduce the size of the clot. In some cases the clot may be removed via a catheter (thrombectomy) Your doctor may prescribe other aids to prevent clotting or further damage such as:
• elastic stockings which will be removed and replaced during the day as required
• inflatable stocking or "booties" which apply alternating pressure to the legs or feet to encourage blood flow. These will also be removed and replaced as required.
The patient can help prevent clots from forming by walking the hospital halls, but if this activity is not possible, exercises performed while in bed can also help:
• tighten and release the buttocks for several seconds frequently throughout the day.
• move the feet up and down, as if working the gas pedal of your car
• pretend you are writing your name or leading an orchestra with your feet. Do this frequently throughout the day
• Change position in bed
Even if you can't leave your hospital bed for a period of time, these leg and feet exercises can help keep circulation healthy.
