There are various forms of anesthesia. The type of anesthesia you get will depend on the type of surgery and your medical condition. Sedatives (to make you sleepy) and analgesics (to ease the pain) may also be used as part of the anesthesia process. The different types of anesthesia include the following:
Local anesthesia
Local anesthesia is an anesthetic agent given to temporarily stop the sense of pain in a particular area of the body. You remain conscious during a local anesthetic. For minor surgery, a local anesthetic can be given via injection to the site, or allowed to absorb into the skin. However, when a large area needs to be numbed, or if a local anesthetic injection will not penetrate deep enough, doctors may use other types of anesthesia.
Regional anesthesia
Regional anesthesia is used to numb only the portion of the body that will undergo the surgery. Usually an injection of local anesthetic is given in the area of nerves that provide feeling to that part of the body. There are several forms of regional anesthetics:
Spinal anesthetic. A spinal anesthetic is used for lower abdominal, pelvic, rectal, or lower extremity surgery. This type of anesthetic involves injecting a single dose of the anesthetic medicine into the area that surrounds the spinal cord. The injection is made into the lower back, below the end of the spinal cord, and causes numbness in the lower body. This type of anesthesia is most often used in orthopedic procedures of the lower extremities.
Epidural anesthetic. The epidural anesthetic is similar to a spinal anesthetic and is commonly used for surgery of the lower limbs and during labor and childbirth. This type of anesthesia involves continually infusing an anesthetic medicine through a thin catheter (hollow tube). The catheter is placed into the space that surrounds the spinal cord in the lower back, causing numbness in the lower body. Epidural anesthesia may also be used for chest or abdominal surgery. In this case, the anesthetic medicine is injected at a higher location in the back to numb the chest and abdominal areas.
General anesthesia
General anesthesia is an anesthetic used to induce unconsciousness during surgery. The medicine is either inhaled through a breathing mask or tube, or given through an intravenous (IV) line. A breathing tube may be inserted into the windpipe to maintain proper breathing during surgery. Once the surgery is complete, the anesthesiologist ceases the anesthetic and you are taken to the recovery room for further monitoring
