How effective is propofol anesthetic?
“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. "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.”
Is propofol a 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. Subsequently, question is, are you awake with propofol?
Can nurses push IV propafol?
Whether RNs may push propofol is ultimately a decision for the state board of nursing. Check with your state's board before deciding on your own personal policy about pushing propofol.
Is propofol moderate sedation?
There is a growing body of evidence supporting the use of propofol in conjunction with small doses of benzodiazepines (eg, midazolam) and/or opiates (eg, fentanyl). With combination therapy, a smaller dose of propofol is required to obtain moderate rather than deep sedation ( 12, 22 ).
What is the reversal agent?
Reversal agents are defined as any drug used to reverse the effects of anaesthetics, narcotics or potentially toxic agents. The controversy on the routine reversal of neuromuscular blockade still exists.
What drugs are used to reverse general anesthesia?
Efficacy and toxicity information is presented for naloxone (as used to reverse opioids), physostigmine (as used for reversal of sedatives), and Flumazenil (a new specific benzodiazepine receptor antagonist).
Does physostigmine reverse propofol?
In summary, we have shown that physostigmine reverses the propofol-induced unconsciousness and associated depression of the ASSR and BIS in human volunteers. The reversal of the unconsciousness and depression of the ASSR and BIS was blocked by pretreatment with scopolamine.
What is the reversal agent for midazolam?
Flumazenil in a dose of 0.15 mg is a safe drug that reverses the sedative effect of midazolam.
Does flumazenil reverse propofol?
Conclusion: The effects of a multi-drug protocol consisting of midazolam, meperidine, and propofol can be significantly reversed by the administration flumazenil & naloxone. Moreover, patients rapidly emerge from deep sedation to full recovery regardless of weather or not reversal agents are used.
How do doctors reverse anesthesia?
Currently, there are no drugs to bring people out of anesthesia. When surgeons finish an operation, the anesthesiologist turns off the drugs that put the patient under and waits for them to wake up and regain the ability to breathe on their own.
What is the reversal agent for rocuronium?
Reversal agents for rocuronium include anticholinesterases and sugammadex. Anticholinesterases work by competing with the neuromuscular blocking agents for acetylcholine receptors and restoring neurotransmission.
What is the reversal agent for diazepam?
Flumazenil (Romazicon®) is the reversal agent of choice for an overdose of benzodiazepines (diazepam or midazolam).

Background Protamine is used to reverse the anticoagulant effects of heparin, but it can have important side effects.
What is atropine an antidote for?
Study objective: Atropine is the preferred antidote for immediate management of toxicity associated with nerve agents or other cholinergic syndromes. A large-scale exposure to a nerve agent or organophosphate insecticide might result in many victims presenting for care within a short period of time.
What is the reversal agent for benzodiazepines?
Flumazenil is a short-acting agent that reverses benzodiazepine-induced sedation. Re-sedation may occur due to its short duration of action, therefore additional doses may be necessary. Flumazenil is not useful for barbiturate- or opioid-induced sedation.
What is neostigmine used to reverse?
Its FDA indication is for the reversal of the effects of non-depolarizing neuromuscular blocking agents after surgery. The use of neostigmine is primarily found in the context of the reversal of neuromuscular blockade during the administration of anesthesia to patients undergoing surgery that require muscle relaxation.
What is neostigmine used for?
Neostigmine injection is used to treat a muscle disease called myasthenia gravis.
Why is Narcan needed after surgery?
Naloxone injection and naloxone prefilled auto-injection device (Evzio) are used along with emergency medical treatment to reverse the life-threatening effects of a known or suspected opiate (narcotic) overdose. Naloxone injection is also used after surgery to reverse the effects of opiates given during surgery.

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]

Transient local pain at the injection site is the most common adverse reaction. This may be decreased by administering IV lidocaine before propofol bolus.
