Anesthesiology

What is Anesthesia?

It is a medication that prevents you from feeling pain during surgery and other procedures.

How is it given to me?

An anesthesiologist or certified registered nurse anesthetist gives you the medication and monitors you.

 There are three main forms of anesthesia:

  • Local anesthesia - numbs only part of your body
  • Regional anesthesia - numbs a large area (ie. epidural)
  • General anesthesia - temporarily puts you into a deep sleep so you don't feel pain during surgery

Safety Tips

  • Make sure you tell your health care providers about all the medicines you take. This includes over-the counter drugs, vitamins, and supplements
  • Do not drink or smoke before surgery. Cigarettes and alcohol can change the way the anesthesia drugs work.

BIS Anesthesia Monitors

UnityPoint Health - Methodist was the first hospital in central Illinois to use the BIS (Bispectral Index) high-tech monitoring system in all its surgical units. The BIS monitor is a non-invasive sensor that is placed on the patient's forehead to continuously monitor brain waves during surgery. BIS technology reduces the risk of patients becoming aware of surgery. Anesthesia awareness occurs under general anesthesia when a patient becomes aware of some or all events during surgery or a procedure, and has direct recall of those events. (The frequency of anesthesia awareness has been found in multiple studies to range between 0.1 percent and 0.2 percent of all patients undergoing general anesthesia nationwide.)
