Anesthesia Used in Your Procedure
All types of anesthesia are administered to keep you comfortable and pain free during surgery, medical procedures or tests. But there are some key differences. The type you receive will depend on factors like the procedure, your health and your preference. The care provided by your anesthesiologist(s) will maximize your safety and minimize risk during your procedure. Every attempt is made to reduce the physical and mental stress associated with all procedures. This can enhance the perioperative experience as well as the healing process.
