The condition has been nicknamed "pump head".
Now don't get me wrong, you don't go in as Albert Einstein and come out as Bo Bo the Chimp. It is more subtle and in a way, more insidious.
You see no one mentions this as a possible side effect. So when you start to notice changes in your mental capabilities it is quite disturbing. There is a simmering, low level of anxiety as it starts to dawn on you that there is something wrong with your brain. You have difficulty concentrating or following the thread of a conversation. You can't remember some one's name or an important date. It is a terrible, depressing feeling to realize that you are just not as smart as you used to be.
So there you sit in the first weeks following your surgery, battered in body and mind, a prime candidate for the crushing depression that often haunts the survivors of open heart surgery.
There is some good news. The impact on your mental capacity while real is relatively short term with noticeable improvements three months out, six out and so on.
Here is what is thought to happen. The combination of prolonged anesthesia and the heart lung machine induce a certain amount of mental confusion and memory loss that is temporary and will diminish over time.
The physical challenge to the body during the process of restoring the body to normal temperature from the cool state it is in while on the pump may deprive the brain of oxygen for a short time. So it is a double whammy. The body and brain are put through an amazing ordeal. It is one of the casual miracles we take for granted in modern society that we come back at all.
If you are presently recovering from open heart surgery and have these symptoms:
- difficulty concentrating
- noticeable changes in mental capabilities
- increased depression
