Anesthesia is used to eliminate the pain felt during laparoscopic surgery. Spinal and general anesthesia are the two most commonly used of types of anesthesia for laparoscopic surgery. One type is spinal anesthesia, which is injected into your lower back and makes you numb from the bottom of your rib cage down. The other kind of anesthesia forlaparoscopic surgery is general anesthesia. This type is given through an IV, and causes you to sleep during the procedure.

General Anesthesia

The other option for laparoscopic surgery is general anesthesia. This type uses medication to put you into a deep sleep so that you do not feel any pain, pressure, or movement during the procedure. In order to do this, you will first be asked to breathe through an oxygen mask. Then you will be given medications through your IV, which will cause you to feel pleasantly relaxed, and you will quickly drift off to sleep. After you are in a deep sleep, a breathing tube will be placed into your windpipe to assist with your breathing throughout the laparoscopy. Your anesthesia care team will give you other medications as required during your procedure through your IV.

Spinal Anesthesia

With spinal anesthesia for laparoscopic surgery, your anesthesiologist will inject medicine into your lower back. This will cause you to feel numb, usually from the base of your rib cage down. To make the placement of the needle easier, you will be asked to either lie on your side, curled up, or to sit on the side of the table, hunched forward. During the laparoscopic surgery, you will also receive medicine that makes you feel relaxed or sleepy. Although the spinal anesthesia will take away all sensation of pain, you might still feel some pressure and movement during the laparoscopy.
