There are different types of anesthesia used for colonoscopies, depending on the patients needs and preferences. Here are the most common options:

• Monitored Anesthesia Care (MAC): This is the most common sedation method used for colonoscopies. It uses the drug propofol, which is administered by a trained professional under constant supervision and monitoring.

• Conscious Sedation: This type of sedation is usually administered by the doctor who performs the colonoscopy. It involves a mild sedative and a painkiller, such as midazolam and fentanyl.

• General Anesthesia: This type of anesthesia is not commonly used for colonoscopies, but it may be the best option for people who have airway abnormalities or are at high risk. It is usually administered by a credentialed anesthesiologist and nurse anesthetist, and it involves the use of the anesthetic propofol.

Its important to note that patients who ask for light sedation are more likely to feel discomfort and perhaps some pain during the procedure. Unless you elect to receive no sedation, you will need to arrange for someone to take you home after the colonoscopy, as it can take a while for the sedative to wear off. If you have any concerns or questions about the type of anesthesia that will be used during your colonoscopy, talk to your doctor.
