what is anesthesia? why it uses!

Anesthesia is the administration of medication to allow medical procedures to be done without pain, and in some cases, without the patient being aware during the procedure. There are a variety of types of anesthesia, as well as several different medical professions that are able to give anesthesia.

Anesthesia is used in a wide range of procedures, from highly invasive surgeries, such as open-heart surgery, to minor procedures such as having a tooth extracted.

THERE ARE FOUR TYPES OF ANESTHESIA:

1.General Anesthesia

General anesthesia is a combination of medications that are intended to make the patient unaware of what is happening around them, to prevent pain, and to paralyze the body during a procedure. Typically used during surgery, general anesthesia allows a physician to provide treatments that would be extremely painful if the patient were awake and able to feel.

• 2.Regional Anesthesia
• 
• Regional anesthesia is a method of pain prevention for surgeries and procedures. In regional anesthesia, only the area of the body that would feel pain is numbed, allowing the patient to have the procedure while awake or while sedated but still conscious.
• 3.Local Anesthesia
• 
• Local anesthesia is a type of pain prevention used during minor procedures to numb a small site where the pain is likely to occur without changing the patient's awareness. You are likely familiar with local anesthetics being used for dental procedures and for numbing an area that needs to be stitched.

• 4.Monitored Anesthesia Care (MAC)
• 
• Monitored Anesthesia Care (MAC), also known as conscious sedation or twilight sleep, is a type of sedation that is administered through an IV to make a patient sleepy and calm during a procedure. The patient is typically awake, but groggy, and are able to follow instructions as needed.

The type of anesthesia used during your surgery typically depends on the type of surgery, your state of health, the length of the surgery and the preferences of your anesthesia provider and surgeon.
