You won't be completely unconscious, but you'll sleep through the procedure and probably have no memory of it. The medication commonly used for deep sedation is propofol, which is not an opioid. It acts fast, wears off quickly, and is safe for most patients.
Most patients choose to be sedated during a colonoscopy, and wake up in the recovery room with little memory of the procedure. Because the bowel does not feel pinching or burning sensations, no pain is experienced if the colonoscopist removes polyps or tissue during the procedure.
Rock explains. Propofol works quickly; most patients are unconscious within five minutes. "When the procedure is over and we stop the intravenous drip, it generally takes only 10 to 15 minutes before he or she is fairly wide awake again.”
You are sedated during the procedure, so you won't feel anything. But you may be groggy afterwards.
Moderate sedation.
This is one of the most common forms of sedation used. The medications are usually midazolam and fentanyl – a mild sedative and a pain killer.
Is a sedation-free colonoscopy painful or uncomfortable? Most patients report little or no discomfort during the procedure. You can request sedation during the procedure if you change your mind and feel you need it, although it has been my experience that this seldom occurs.
While we use general anesthesia in some cases, most of our patients get monitored anesthesia care now for colonoscopies. That means going to sleep in one room and then waking up in the recovery area, in terms of what you might remember about it.
Pain after the colonoscopy
Some people experience mild stomach pain for a day or two after the procedure. A person may also have temporary changes in digestion, such as constipation or diarrhea. If the tube irritates the rectum, anus, or intestines, there may be some discomfort when having a bowel movement.
Mild abdominal pain/discomfort immediately after a colonoscopy is not rare, occurring anywhere between 2.5% to 11% of the cases [2]. Though it may have a host of etiologies, it is most commonly a result of air insufflation, endoscope looping, and/or manual pressure maneuvers used during a colonoscopy.
One of the causes of pain during insertion of the colonoscope is stretching of the mesenterium by loop formation of the instrument and the degree of the pain is different from types of looping formation.
You'll need to stay in the recovery area to wake up from the sedative medications, and you'll need someone to help get you home safely since you may be sleepy from the sedative for a few hours. You may pass a lot of gas (the air the doctor pumped into your colon) during the hours following the colonoscopy.
The medicine you received during the procedure may stay in your body for up to 24 hours. You may feel tired or sleepy and have difficulty concentrating. Once you get home, relax for the rest of the day.
Colonoscopy Recovery: After the Procedure
The effects of the sedation could last up to a day, so you should not drive or operate any machinery until the following day. You may feel gassy or bloated for a while after the procedure because of the air that was injected into your intestine during the colonoscopy.
After your procedure:
You will be discharged when you are alert and stable. The doctor or nurse will speak to you about your plan of care. Remember you must have an escort to drive or accompany you home. You may return to work the morning after your colonoscopy (Not the evening of the colonoscopy).
Following a normal colonoscopy, most patients are ready to return to work and all other routine activities 24 hours after the procedure.
The biggest culprits that will show up in a colonoscopy and obscure our view are foods like nuts, seeds and high-fiber cereals. You also want to avoid granola, coconut, dried fruit and fresh fruit with the skin on, like apples and pears, or fruit with seeds, like strawberries and raspberries.
What if I've taken all my preparation and am still passing solid stool on the day of my exam? In this case, your procedure will need to be rescheduled. You may be prescribed a different preparation for your next procedure. Please call the triage nurse to reschedule your procedure with a different preparation.
As with any invasive procedure, complications may occur. Complications related to colonoscopy include, but are not limited to, the following: Continued bleeding after biopsy (tissue sample) or polyp removal. Nausea, vomiting, bloating or rectal irritation caused by the procedure or by the preparatory bowel cleansing.
If you can't pass gas soon after surgery, it may mean that a post-operative ileus, or gastric delay, is happening. A post-operative ileus or POI is when there's a slowdown in your body's ability to digest food. It could be caused by changes in your nervous system or the after-effects of having your intestines handled.
Usually if a suspected colorectal cancer is found by any screening or diagnostic test, it is biopsied during a colonoscopy. In a biopsy, the doctor removes a small piece of tissue with a special instrument passed through the scope. Less often, part of the colon may need to be surgically removed to make the diagnosis.
After the test, you may be bloated or have gas pains. You may need to pass gas. If a biopsy was done or a polyp was removed, you may have streaks of blood in your stool (feces) for a few days. Problems such as heavy rectal bleeding may not occur until several weeks after the test.
Many patients are so comfortable that they do not even realize the procedure was completed. Your body is completely covered during the exam. You may be wondering how much of your body is exposed during a colonoscopy.
Summary. Post-surgical throat pain is common and can be due to dehydration or irritation from any tubes put in your throat to keep you breathing during surgery. The irritation usually improves in a few days and should be gone in about a week.
Most colonoscopies take only 15-30 minutes to complete.
