General Anesthesia

General anesthesia is a method used to stop pain from being felt during a procedure or surgery. In this form of anesthesia medication is given to make the person unconscious.

General anesthesia is the most powerful form of anesthesia. It is usually reserved for major surgery such as surgery inside the skull neck chest abdomen and pelvis.

General anesthesia uses medication to make a person unconscious. Medications are commonly breathed into the lungs or injected into the veins through an intravenous line inserted into the vein of the hand or arm. An individual may also be paralyzed with other medications to prevent movement during the surgery.

A ventilator or artificial breathing machine breathes for the person during the procedure. This is because the chest muscles are paralyzed. A ventilator requires a tube to be put into the windpipe known as endotracheal intubation. The tube goes through the mouth and into the windpipe. Oxygen and inhaled medication can then be delivered to the lungs.

The person is watched closely during the procedure. The oxygen levels in the blood pulse blood pressure and other functions are monitored. Fluids are usually given through an intravenous line to prevent dehydration and low blood pressure.

The individual is totally asleep and unable to feel pain during the surgery. When the procedure is complete the medication is turned off. The person will have no memory of the surgery when he or she wakes up.

After surgery the person is taken to an area called the surgery recovery room. When the person can breathe independently the ventilator is turned off. It may take several minutes for the person to wake up and he or she may feel groggy at first. Gradually the person wakes up and begins the recovery process.

The person may need to stay in the hospital for a few days to recover from the procedure. Often the person can go home after a few hours. The person must be stable and feel well enough to go home and someone must be available to drive the person home. The medications cause coordination problems and slowed reflexes for several hours after surgery. A person should not drive for at least 12 hours after the procedure. Some people may take a few days to feel that they are back to normal.

The most feared complication of general anesthesia is death. This occurs in roughly 1 out of every 10000 people. It is not possible to predict who will have this type of severe reaction.

The medications used in general anesthesia can cause severe reactions. These include liver damage kidney damage seizures low blood pressure and allergic reactions. Nausea is fairly common for a few hours after the procedure.
