In reality, however, responses to different sedatives vary greatly among patients, according to Yale Medicine. Drugs used for conscious sedation include midazolam Versed and fentanyl. Anesthesia drugs, on the other hand, produce a deeper sedation and have to be administered by an anesthesiologist or a nurse anesthetist while the gastroenterologist performs the colonoscopy.
Two doctors rather than a doctor and a nurse, as during conscious sedation are present because of the higher sedation and the associated risks like low blood pressure or slowed breathing , for which they can give other drugs or more aggressive oxygen therapy, according to Temple Health.
Different colonoscopy facilities have different preferences when it comes to sedation. Ashcraft prefers to use anesthesia, because it leaves him free to focus on the actual colonoscopy. Here are the three main drugs used to sedate colonoscopy patients. Often, doctors use more than one. According to an analysis of 1. It induces a state of conscious sedation and is a benzodiazepine, a class of medication which also includes Xanax.
Midazolam slows brain activity, so after being sedated with it, you most likely won't remember the procedure. Midazolam is often used in combination with the narcotic drug fentanyl.

Major medical societies recommend screening for colorectal cancer beginning between the ages of 45 to For most patients, a sedative is given in intravenous form to help relax and minimize any discomfort during the procedure. But did you know that using a sedative is optional? In many countries, sedation-free colonoscopies are the norm.
Patients are alert and engaged during the procedure. Saving time is the greatest benefit of a sedation-free colonoscopy. If you are sedated for your colonoscopy, you will have restrictions after the procedure until the next day, such as not being able to drive or return to work. You will require a ride home after your procedure, which also may cause your driver to take time off from work. After a sedation-free colonoscopy, you can resume normal activities right away — you can drive, run errands and generally get on with your day.
The second benefit is increased safety. Overall, the sedatives used for colonoscopies are very safe, but there is a small risk of side effects, such as drops in blood pressure, breathing problems, vomiting and prolonged sedation. Prevalence of anesthesia use during colonoscopy varied significantly by region: more than half in the Northeast; and less than one in 10 in the West.
Use of anesthesia was lowest in Washington state. Risk of day colonoscopy complications with anesthesia services also varied by region: In the Northeast, use of anesthesia was linked to a 12 percent rise in the risk of any complication; by contrast, in the West, it was linked to a 60 percent increase in risk.
Future studies should attempt to confirm these results, while controlling for confounders, such as patient risk factors which might make them more likely to receive deep sedation during colonoscopy.
