Anesthesia means lack of sensation. It prevents patients from feeling the surgery or medical procedure. Normally, nerves from every part of the body send signals to the spinal cord. The spinal cord relays these messages to the brain. The brain then interprets the signals as pain or other sensations. Anesthesia temporarily interrupts this relay system. The three main types of anesthesia are:

• General Anesthesia


• Regional Anesthesia


• Local Anesthesia
