Anesthesia, is a procedure that a patient will undergo if they’re going to surgery. When you’re under surgery, you can’t stand the pain of having cuts through your skin, so you have to have injections to produce anesthesia, where you will lose your pain sensation or in some case, you will not be aware of your pain.
There are three types of anesthesia : local anesthesia, regional anesthesia, general anesthesia, and dissociative anesthesia.
What is local anesthesia? Local anesthesia block sensory perception within a specific location on the body, such as a tooth or the urinary bladder.
What is regional anesthesia? Regional anesthesia blocks transmission of nerve impulses between a part of the body and the spinal cord. Two frequently used types of regional anesthesia are spinal anesthesia and epidural anesthesia.
What is general anesthesia? General anesthesia blocks sensation of the sensory, motor and sympathetic nerve transmission at the level of the brain, resulting in unconsciousness and lack of sensation.
What is dissociative anesthesia? Dissociative anesthesia blocks transmission of nerve impulses between higher centers of the brain (such as the cerebral cortex) and the lower centers, such as those found within the limbic system. Anesthesia is an important concept in the medical field since they can’t do much without putting patients under anesthesia. You should know about your options for anesthesia since you will need it.
