How much propofol is given for colonoscopy?
This was similar to the nurse-administered propofol sedation (NAPS) technique described by Rex et al (3), who noted that the dose of propofol required to initiate the colonoscopy may vary from 30 to >200 mg. If the patient seemed to experience discomfort during the procedure, a 10- to 20-mg bolus was delivered.

Can rats sleep with propofol?
What we found is that recovery in rats given propofol occurred as quickly as recovery in rats allowed to sleep normally. We concluded that, at least in rats, subjects can discharge their sleep debt under propofol sedation to the same degree as they are able to do it using naturally occurring sleep.
Is propofol sedation like sleep?
Propofol sedation is nothing at all like sleep. Sleep is reversible with external stimulation - if you shake somebody, they wake up. Propofol is obviously not like that. Sleep shows a characteristic pattern of EEG behavior, while propofol does not. (For instance, Tung explains, cyclical patterns of REM and nonREM sleep are not observed during propofol sedation, in rats or humans) Sleep, in general, preserves blood pressure and the ability to breathe and propofol does not. They are very different states.

What is the best gas for anesthesia?
Nitrous Oxide (N2O) is a commonly used anesthetic gas of modest potency. By itself, N2O cannot produce a general anesthetic. It is typically used in a concentration of 50%, as an adjunct to sevoflurane or narcotics. The advantages of N2O are that it is inexpensive, it wears off quickly, and it has a reliable safety record. Dentists sometimes use N2O to bring on inhaled sedation when they are doing office procedures such as filling a cavity.

How long before a propofol injection can you use lidocaine?
Lidocaine can be used to blunt this discomfort by being injected about 30–45 seconds prior to the Propofol induction injection. Lidocaine can also be used during the induction of general anesthesia to blunt the reflex to direct laryngoscopy. Prior to ‘mixing’ any formulation or brand of Propofol (Diprivan or di-isopropylphenol) to be used for the induction of general anesthesia, I would run BOTH the type of di-isopropylphenol and type of lidocaine by an in-house pharmacist. The reason is that formulations changes with time and experience and what you do not want is to find out that ‘mixing’ the two specific types you have in your hand at the moment is incompatible because of a new preservative or pH issue.
How long does it take for a patient to wake up from sedatiom?
If propofol is the only drug used for sedatiom, the patient will wake up spontaneously in about 7–10 minutes unless the case is much longer. Propofol is extracted fry the circulation by the liver and metabolized using the cytochrome P 450 enzyme system. This removal of propofol by the liver is a very consistent time that is very reliable.

Is Propofol painful on injections?
Propofol is painful on injection. Isn't lidocaine used to prevent this?
Can you mix propofol and lidocaine?
In my practice, I did not mix these drugs. The lidocaine works by ‘numbing’ the pain receptors of the blood vessel itself. This effect is temporary, minutes only, so that is why one times the Propofol injection about 30–45 seconds after the lidocaine injection for maximum reduction in pain, and why I chose not to mix these two medications.
Does propofol cause pain?
Propofol, also known as Diprivan or di-isopropylphenol, is an intravenous anaesthetic induction agent. It is wonderful for short surgical cases. Sadly, chemically speaking, most -phenols cause irritation to the skin and membranes. Pain on injection with propofol can be very distressing to the patient. The incidence of pain (in review articles) varies between 30% and 90+% in adults during induction of anaesthesia. Pain generally occurs 5–20 seconds after injection and most believe it is this direct irritation of the blood vessels that causes the pain, most likely by the -phenol group in the dru
Is propofol a twilight sedation?
When Propofol is used as the main medication for sedation for an EGD (endoscopy) or a colonoscopy, it is no longer considered “twilight” sedation and becomes “MAC” type sedation which stands for “Monitored Anesthesia Care” and reauires an anesthesiologist present, as the need for intubation is possible. I saw and assisted on many of these in rotation and had an EGD with MAC myself and also needed to be intubated and it was nothing. I didn’t even know when I woke up. (This is an uncommon occurrence and only happened with me (they even anticipated it with me) due to on
How long before wakeup should you take propofol?
at a rate of 50 mcg/kg/min) but if you do, I recommend turning off the infusion at least 10 minutes before planned wakeup.

Does propofol reduce sleepiness?
This allows adequate time for the drug to redistribute and for serum propofol levels to decrease enough to avoid residual sleepiness. Sevoflurane. Sevoflurane is relatively insoluble and its effects wear off quickly when the drug is ventilated out of the lungs at the conclusion of surgery.
Can you use desflurane instead of sevoflurane?
You may choose to administer desflurane instead of sevoflurane. You may choose sufentanil, morphine, or meperidine instead of fentanyl. My advice still applies. Use as little narcotic as is necessary, and try not to administer intravenous narcotic during the last 30 minutes of surgery.
Can you spray lidocaine into the trachea?
Intra-tracheal lidocaine. I recommend spraying 4 ml of 4% lidocaine into the larynx and trachea at laryngoscopy prior to inserting the endotracheal tube. I can’t cite you any data, but it’s my impression that patients demonstrate less bucking on endotracheal tubes at awakening when lidocaine was sprayed into their tracheas. Less bucking enables you to decrease anesthetic levels further while the endotracheal tube is still in situ.
What is the best sedation for colonoscopy?
At Yale Medicine, anesthesiologists caring for patients who want deep sedation for their colonoscopy typically use a drug called propofol. “It is a short-acting anesthetic that has the advantage of wearing off relatively quickly,” Dr. Rock explains.

Is propofol safe for colonoscopy?
Propofol is considered safe and effective for most patients, but there are some side effects that need to be considered. The drug may lower blood pressure and cause slower breathing. If you have very low blood pressure or heart and/or breathing problems, your doctor may advise against using propofol for your colonoscopy.
