What sedation is used for colonoscopy?

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.

What kind of anesthesia is used for colonoscopy?

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.

Is colonoscopy painful without sedation?

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.

How long does a colonoscopy with sedation take?

It should take 30 to 45 minutes to have your colonoscopy. But you might be at the hospital for around 2 hours from getting there to going home. You'll usually be told if any growths (polyps) have been removed. You'll then be moved to the recovery room.

How will I feel after propofol?

Patients sedated with propofol rarely complain of feeling "drugged" and more often remark that they feel as if they had a great nap. While fentanyl and other opioid-type drugs may cause nausea, particularly at higher doses, this is rare with propofol.

Intravenous Sedation for Endoscopy Colonoscopy

How long does propofol take to wear off?

The half-life of elimination of propofol has been estimated to be between 2 and 24 hours. However, its duration of clinical effect is much shorter, because propofol is rapidly distributed into peripheral tissues. When used for IV sedation, a single dose of propofol typically wears off within minutes.

Why was my colonoscopy so painful even with sedation?

If your doctor introduced air into your bowel during the procedure, there's a small chance you may feel some gas-like cramping after your colonoscopy. If your doctor performed a biopsy, you may have mild discomfort the next day. If you do experience pain afterward, talk to your doctor.

Why did I wake up during colonoscopy?

The condition, called anesthesia awareness (waking up) during surgery, means the patient can recall their surroundings, or an event related to the surgery, while under general anesthesia. Although it can be upsetting, patients usually do not feel pain when experiencing anesthesia awareness.

Is propofol safe for a colonoscopy?

Background. Propofol-mediated sedation is safe and clearly associated with increased patient satisfaction. However, whether it results in a favorable effect on colonoscopy outcomes and performance compared to standard sedation with benzodiazepines/opiates remains unclear.

How do they put you to sleep for a colonoscopy?

During your colonoscopy, you'll lie on your left side on an exam table. You'll get sedatives through an IV in your arm, and you'll go to sleep. During the procedure, the doctor puts a tube-like instrument called a colonoscope into your rectum. It's long but only about a half-inch across.

Is propofol the same as general anesthesia?

Propofol is used as an “induction agent”—the drug that causes loss of consciousness— for general anesthesia in major surgery. In lower doses it is also used for “conscious sedation” of patients getting procedures on an outpatient basis at ambulatory surgery centers.

Is moderate sedation included in colonoscopy?

In addition, the ACA amended Section 1833(b)(1) of the Act to waive the Part B deductible for screening colonoscopies, which includes moderate sedation services as an inherent part of the screening colonoscopy procedural service.

Why do they give you oxygen during a colonoscopy?

The authors conclude that administration of oxygen via nasal prongs can reduce the risk of hypoxemia during colonoscopy. However, since hypoxemia may occur even when nasal oxygen is given, continuous monitoring of arterial oxygenation is recommended.

How fast does propofol work?

Onset of action: Propofol has a rapid onset of action that is dose-dependent and less than a minute. Duration of action: An induction dose of propofol will have a clinical effect for approximately 10 minutes.

Is propofol conscious sedation?

Propofol (2,6-diisopropyl phenol) is an intravenous anesthetic agent that is often used in conjunction with other agents, such as nitrous oxide and muscle relaxants, for general anesthesia. However, when used in lower doses, it induces conscious sedation. There are several advantages of propofol.

How is a colonoscopy performed on a woman?

The long and winding female colon. A colonoscopy works like this: A patient lies on their side while a gastroenterologist inserts a colonoscope — essentially a camera on the end of a long, flexible tube — into their anus. From there, the doctor can use the scope to navigate through the entire large intestine.

Do you get a urine catheter during a colonoscopy?

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 be given an appointment to visit the surgical outpatient department for a check-up about one month or so after you leave hospital.

Can you resist anesthesia?

Patient physiology

Some patients may be more resistant to the effects of anesthetics than others; factors such as younger age, obesity, tobacco smoking, or long-term use of certain drugs (alcohol, opiates, or amphetamines) may increase the anesthetic dose needed to produce unconsciousness.

How do I get over my fear of a colonoscopy?

Why am I in so much pain after a colonoscopy?

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.

Do they give you pain meds after a colonoscopy?

You may be aware and able to respond if your doctor wants you to do something, like hold your breath, but you should not feel pain, and the anesthesia should alleviate any anxiety related to the procedure. You may also be given some sort of pain medication.

Do you stop breathing with propofol?

What side effects does propofol have? It can cause a decrease in blood pressure, it can depress or even stop breathing, and it can cause pain on injection.

Can you drive after having propofol?

Purpose: Propofol is a short-acting medication with fast cognitive and psychomotor recovery. However, patients are usually instructed not to drive a motor vehicle for 24 hours after receiving propofol.

Is propofol moderate or deep sedation?

The use of propofol increases the success of satisfactory deep sedation, but it can produce rapid and profound decreases in level of consciousness and cardiorespiratory function. Data are needed to assess the safety of this drug outside an anesthesiology setting.
