Tissue plasminogen activator (TPA)
There is opportunity to use alteplase (TPA) as a clot-buster drug to dissolve the blood clot that is causing the stroke. There is a narrow window of opportunity to use this drug. The earlier that it is given, the better the result and the less potential for the complication of bleeding into the brain.
Present American Heart Association guidelines recommend that if used, TPA must be given within three hours after the onset of symptoms. Normally, TPA is injected into a vein in he arm. The time frame for use can be extended to six hours if it is dripped directly into the blood vessel that is blocked. This is usually performed by an interventional radiologist, and not all hospitals have access to this technology. Read more…
What are blood clots?
Blood is a liquid that flows within blood vessels. It is constantly in motion as the heart pumps blood through arteries to the different organs and cells of the body. The blood is propelled back to the heart in the veins. When muscles contract, they squeeze the veins and allow the blood to be pushed back to the heart.
Blood clotting is an important mechanism to help the body repair injured blood vessels. Blood consists of: Read more…
A blood transfusion is the transfer of blood or blood products from one person (donor) into another person’s bloodstream (recipient). This is usually done as a life saving maneuver to replace blood cells or blood products lost through severe bleeding, during surgery when blood loss occurs or to increase the blood count in an anemic patient. The following material is provided to all patients and/or their family members regarding blood transfusions and the use of blood products. Although in most situations the likelihood of a blood transfusion associated with surgery is uncommon, at times patients may require blood products. You are encouraged to discuss your particular risk of transfusion with your doctor. Read more…
We live in a very narrow range of normal. In the range of normal, the body performs well, but once we slip outside the norm, the body spirals slowly out of control. We take most of the internal controls of our body for granted since they are on autopilot, but many people need to fly manually.
The body’s cells need two energy requirements to function. The blood stream delivers both oxygen and glucose to the front door of the cell. The the oxygen is invited in, but the glucose needs a key to open the door. The insulin molecule is that key. When we eat, the body senses the levels of glucose in the blood stream and secretes just the right amount of insulin from the pancreas so that cells and the body can function. Read more…
