Almost all colonoscopies in the United States are performed with patients under a level of sedation or anesthesia that prevents them from feeling anything. Often, patients are asleep for the entire procedure.
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.
On the day of the procedure, you will likely be given an anaesthetic so you don't feel any pain or discomfort. As you may feel drowsy or weak prior to and after the colonoscopy it is best to arrange someone to drop you off at the hospital before the procedure and take you home afterwards.
Most often, either moderate sedation or deep sedation with the anesthetic propofol are used for colonoscopies. An anesthesiologist is sometimes present for moderate sedation — sometimes called conscious sedation by patients, though the term is technically incorrect.
Previous studies have reported that 74% of patients felt no pain or only mild discomfort during unsedated colonoscopy. Thus, routine administration of sedative or analgesic agents to all patients was considered unnecessary. However, unsedated colonoscopy is considered an option for some but not for all patients.
In many countries, sedation-free colonoscopy is the norm, he notes, explaining how it's cheaper, quicker and more efficient, as there's no wait time for a sedative to kick in nor are there expenses associated with starting an IV and administering the medicine.
During the procedure itself, your colonoscopy will not be painful at all. Most patients cannot even feel the tube when it is inside of them, and there is no pain during the post-procedure process. There are a few side effects that may occur after the procedure, which include: Distention.
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.”
A colonoscopy procedure typically takes 30-60 minutes, depending on whether the doctor needs to remove polyps or take biopsies. However, patients and caregivers should plan to spend 2-3 hours total at the hospital or endoscopy center to account for the time needed for preparation and recovery.
After a colonoscopy, you will need to recover from the effects of the sedation, which usually wear off within 30 minutes, and you may need to rest after your colonoscopy preparations. You may experience some discomfort and mild pain in the abdominal area as air is relieved from the procedure and leaves your colon.
Colonoscopy recovery is usually quick with most people resuming normal activity the next day. Even so, it is important not to rush back to work. It is best to take the remainder of the day to rest, recover from sedation, and replenish fluids and nutrition. The results of your exam should be available within a few days.
Even if you are in good health, you'll need to ask for a caregiver for your colonoscopy. Most colonoscopy procedures include sedation or anesthesia to provide comfort and prevent pain. Sedation can make you groggy, uncoordinated and weak.
Most colonoscopies take only 15-30 minutes to complete. As a reminder, most patients recall feeling minimal to no pain or discomfort during the procedure. After the colonoscopy is done, you will be observed in a recovery area until the effects of the anesthesia wear off.
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.
You may need a catheter (fine plastic drain tube) put in your front passage to drain the urine from your bladder until you are able to pass urine comfortably on your own.
You may keep most clothing on for upper endoscopy as well as comfortable shirt and socks for colonoscopy. Women may keep their bra on for the procedure. Please do not wear lotions, oils or perfumes/cologne to the center due to the monitoring devices.
Screening colonoscopy for colorectal cancer is a commonly performed procedure with an established survival benefit. Up to one-third of patients experience abdominal pain, nausea, or bloating afterward, which may last hours to several days.
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.
You'll lie on your side, and the procedure will take 30 to 60 minutes. Your doctor will put the tube inside your rectum and up your colon. First, air blown through the tube widens your colon. This makes it easier to see what's inside.
Conclusions: Combining colonoscopy with three-quadrant hemorrhoidal ligation is a safe and effective method of treating symptomatic internal hemorrhoids. The procedure is convenient for both physician and patient and makes more efficient use of time and resources.
Bleeding is one of the most common complications of colonoscopy, accounting for 0.3-6.1% of cases[35,36].
Do not shave your abdomen (stomach) or pubic hair. Shaving before your surgery gives you a higher chance of getting an infection. A person from the health-care team will use clippers to get you ready for surgery if hair needs to be removed.
Colonoscopies performed in the afternoon (PM) have been shown to have lower adenoma detection rates (ADR) compared to those in the morning (AM). Endoscopist fatigue has been suggested as a possible reason. Colonoscopies tend to be technically more challenging in female patients.
You can start eating regular foods the next day. Keep eating light meals if you are not able to pass gas and still feel bloated. For the first 24 hours after your procedure: Do not drink alcohol.
