ANESTHESIA and SEDATION
Anesthesia controls pain during surgery or other medical procedures. The anesthesia you receive depends on your health, history, the surgery and your choices. Anesthesia has risks. You will talk with your anesthesia provider about the risks and benefits of anesthesia on the day of surgery. Together, you will decide which type of anesthesia is best for you there are three basic types of anesthesia:
1. General Anesthesia affects the entire body. You have no awareness or feeling. You may breathe gases or vapors through a mask or tube. An anesthesia provider chooses a way to make sure oxygen and gases can move in and out of your lungs easily. Usually this means the provider places a tube in your airway. The anesthesia provider may also give you medicine through an intravenous (IV) tube in your vein. You may have a sore throat or feel sick to your stomach after surgery.
2. Regional Anesthesia produces a loss of feeling to a specific region of the body. An anesthesia provider will give you a shot to numb the region that needs surgery. You may be awake during surgery or you may have sedation.
a. Spinal Anesthesia produces a loss of feeling in your body below the waist. You will sit up or lie on your side while an anesthesia provider injects medicine into your lower back. You will not be able to move your legs when the medicine starts to work. It may take longer for the spinal anesthesia to wear off than general anesthesia.
b. A Peripheral Nerve Block is an injection near a group of nerves to produce a loss of feeling in a specific area of your body or extremity (arm, foot, shoulder) that needs surgery. You may have sedation during a peripheral nerve block. i. An arm block is an injection in your armpit or above the collarbone of the arm that needs surgery. ii.A foot block is an injection behind your knee or in your foot to produce a loss of feeling in your foot. iii. A shoulder block is an injection in your lower neck to produce a loss of feeling in your shoulder.
3. Local Anesthesia produces a loss of feeling to a small, specific area of the body. Your physician or an anesthesia provider will give you a shot to numb the area. You will be awake during surgery.
Sedation is the use of drugs to relax you. You may have sedation alone or with anesthesia. With sedation:
1. You may feel relaxed and awake. You can answer questions and follow directions.
2. You may feel relaxed and drowsy. You may sleep through much of the procedure. You may hear sounds and voices around you. You easily awaken when someone touches or speaks to you.
