The effects of anesthesia
Very diverse could be the consequences of anesthesia. People who have had anesthesia are frequently observed phenomena such as decrease in performance, impaired memory, impaired learning abilities. In medicine such manifestations of the condition after anesthesia is called postoperative cognitive dysfunction. Memory impairment after anesthesia is delivered to patients a lot of trouble. These people immediately began to be troubled by several questions: what happened after the anesthesia with their memory of how long it will last, what can be done to ease symptoms. Anesthesiologists can't give an exact answer to any of these questions. This is due to the fact that medical courses and faculties are not provided no information on memory impairment after anesthesia.
Memory impairment after anesthesia
Complications such as memory impairment after anesthesia is not uncommon. Many studies that relate post anesthetic cognitive impairment, were associated with heart surgery. According to statistics, in the first week after anesthesia in 30-80% of patients cardiac surgery there are complications with memory. Patients other operations have a lower risk of loss of memory. There are works that show that post-anesthesia cognitive disorders can persist from one year and more.
What kind of anesthesia most harmless
Scientists have been searching for the answer to the question, what type of anesthesia has the least impact on the brain. However, consensus still does not exist. Some experts believe that violations of such cognitive functions as memory, attention and learning, occur with the same frequency as in General anesthesia and regional anesthesia techniques (spinal and epidural anesthesia). Others are of the opinion that regional anesthesia is associated with fewer incidents of impaired memory and attention. It is impossible with absolute precision to determine whether the harmless drug used for anesthesia, or poses any danger to humans. It is believed that the development of memory impairment during anesthesia matter sharp shifts in the delivery of oxygen to the brain.
Factors that increase the risk of memory disorders
Causes of intellectual impairment after anesthesia is still unclear. But scholars have identified several factors that increase the risk of getting such complications. First, at risk of to reduce the level of memory of elderly people. Second, memory impairment often seen in people who have had anesthesia again. Third, if the operation lasted long period of time, then the chances of loss of memory increase dramatically. Fourth, the cause for memory impairment after anesthesia can infectious and respiratory complications after surgery.
