Is propofol general anesthesia or sedation?
Propofol is an intravenous anesthetic used for procedural sedation, during monitored anesthesia care, or as an induction agent for general anesthesia. It may be administered as a bolus or an infusion, or some combination of the two.
Is propofol considered 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.
Is propofol a strong sedative?
Propofol is a strong anesthetic that's used for surgery, some medical exams, and for sedation for people on ventilators -- never as a sleep aid. It's given by IV and should only be administered by a medical professional trained in its use.
How long does propofol keep you sedated?
The elimination half-life of propofol is approximately 0.5 h to 1.5 h. This drug has a very fast clearance and therefore can be administered as a continuous infusion or as multiple boluses without any accumulative effects.
Are you awake on propofol?
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.
Are you conscious with propofol?
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.
What is the safest sedation 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.
What is the main side effect of propofol?

Do you talk while on propofol?
Patients do not talk during the anaesthetic while they are unconscious, but it is not uncommon for them to do so during emergence from anaesthesia. The first thing most people ask is 'When are you going to start?
How much Propofol is used for endoscopy?
Generally, a propofol loading dose of 40 mg to 50 mg is given with further smaller bolus loads (10 mg to 20 mg) to maintain sedation, with a typical total dose between 100 mg and 300 mg.
How much propofol is given during surgery?
To provide sedation during surgical and diagnostic procedures, doses and administration rates should be adjusted according to the clinical response. Most patients will require 0.5 - 1 mg propofol/kg body weight over 1 to 5 minutes for onset of sedation.
What is considered deep sedation?
Deep Sedation/Analgesia is a drug-induced depression of consciousness during which patients cannot be easily aroused but respond purposefully** following repeated or painful stimulation. The ability to independently maintain ventilatory function may be impaired.
What is deep sedation anesthesia?
Deep sedation is nearly the same as general anesthesia, meaning that the patient is deeply asleep though able to breathe without assistance. Deep sedation with a medication called propofol is often used for procedures such as upper endoscopy or colonoscopy.
What is Deep Sleep sedation?
Deep sedation is defined as “a controlled, pharmacologically induced state of depressed consciousness from which the patient is not easily aroused, and which may be accompanied by a partial loss of protective reflexes, including the ability to maintain a patent airway independently and/or respond purposefully to ...
What is the difference between moderate and deep sedation?
Moderate – You will feel drowsy and may even fall asleep during the procedure. You may or may not remember some of the procedure. Deep – You won't actually be unconscious, but you'll sleep through the procedure and probably will have little or no memory of it.
What is propofol used for?
Continuing Education Activity. Propofol is an intravenous anesthetic that is used for procedural sedation, during monitored anesthesia care, or as an induction agent for general anesthesia. It may be administered as a bolus or an infusion or some combination of the two. Propofol is prepared in a lipid emulsion which gives it ...
What is in Propofol formula?
The formula contains soybean oil, glycerol, egg lecithin, and a small amount of the preservative EDTA. Strict aseptic technique must be used when drawing up propofol as the emulsion can support microbial growth. [1][2][3] Clinical uses of Propofol:
What is the lipid emulsion used to make propofol?
Propofol is prepared in a lipid emulsion which gives it the characteristic milky white appearance. Strict aseptic technique must be used when drawing up propofol as the emulsion can support microbial growth. It has both approved and off label uses.
How long does propofol take to work?
Duration of action:An induction dose of propofol will have a clinical effect for approximately 10 minutes.
How old do you have to be to get anesthesia?
Induction of general anesthesia in patients ≥ three years old, though it may be used as an induction agent if a child less than three years of age has IV access.
Is propofol an infusion or bolus?
It may be administered as a bolus or an infusion or some combination of the two. Propofol is prepared in a lipid emulsion which gives it the characteristic milky white appearance.
Does propofol affect the brain?
Like most general anesthetic agents, the mechanism of action for propofol is poorly understood but thought to be related to the effects on GABA-mediated chloride channels in the brain. Propofol may work by decreasing the dissociation of GABA from GABA receptors in the brain and potentiating the inhibitory effects of the neurotransmitter. This, in turn, keeps the channel activated for a longer duration resulting in an increase in chloride conductance across the neuron, causing a hyper-polarization of the cell membrane, making it harder for a successful action potential to fire. [4]
Does propofol lower heart rate?
Propofol sedation is associated with generally good haemodynamic stability but induces a dose-dependent decrease in blood pressure and heart rate.
Is propofol a titratable drug?
The depth of propofol sedation increases in a dose dependent manner. The short context-sensitive half-time of propofol, even with prolonged periods of infusion, make this a readily titratable drug for production of IV sedation.
Does propofol help with stress?
Propofol also provides control of stress responses and has anticonvulsant and amnestic properties. In comparison to midazolam, propofol produces faster recovery. Even after periods of prolonged sedation (>72 hours), propofol was generally associated with a faster time to recovery than midazolam.
Is propofol a sedative?
Propofol sedation has been administered as a sedative during mechanical ventilation in the ICU in a variety of patient populations including postoperative patients and patients with head injury.
Does propofol help with tracheal extubation?
Propofol sedation is also associated with shorter weaning time and earlier tracheal extubation compared to midazolam in mechanically ventilated patients. In patients sedated following head trauma, propofol reduces or maintains intracranial pressure.
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. Propofol works quickly; most patients are unconscious within five minutes.
Who administers colonoscopy sedation?
If you have conscious sedation, it is usually administered by the doctor who performs your colonoscopy. If you undergo general anesthesia (also known as full or deep sedation), you can expect to be monitored by a credentialed anesthesiologist and nurse anesthetist.
Why do anesthesiologists attach drips to the arm?
For patients in good health, whose heart and blood pressure are working normally and who are breathing well , the anesthesiologist will attach an intravenous drip to the arm. This helps to make sure that the drug flows correctly and consistently into the vein.
What is colonoscopy procedure?
A colonoscopy is a procedure in which a doctor examines your large intestine (also called your colon) to look for and remove growths that could be precancerous or cancerous.
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.
Does Yale Medicine have an anesthesiologist?
According to Dr. Rock, Yale Medicine's anesthesiologists are highly focused on patients' safety as well as their comfort. “Every patient undergoing anesthesia for colonoscopy here has an anesthesiologist and/or nurse anesthetist looking after them during the procedure," he says.
