Special considerations when conducting moderate sedation
Take away one item you may have learned today and use or at least remember in practice

Definitions
Minimal Sedation
Moderate Sedation
Deep Sedation
Anesthesia
Minimal Sedation
Create Anxiolysis
A drug induced state during which patients respond normally to verbal commands
Moderate Sedation
Conscious Sedation
A drug induced depression of consciousness during which the patient responds purposefully to verbal commands
Deep Sedation
AKA ‘Room air general’
A drug induced depression of consciousness during which patients cannot be easily aroused but respond purposefully after repeated or painful stimulation
Anesthesia
A drug induced loss of consciousness during which patients are not arousable, even with painful stimulation
-CV changes-Loss of airway reflexes

Murphy’s Law
1. If anything can go wrong, it will.
2. If there is a possibility of several things going wrong, the one that will cause the most damage will be the first one to go wrong.
3. If anything just cannot go wrong, it will anyway.
4. If you perceive that there are four possible ways in which something can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.
Murphy’s Law continued
4.5 An IV will work fine in the holding area, but when you get to your procedure room, it will not work fine and will stop working when you need it the most.
5. Left to themselves, things tend to go from bad to worse.
6. If everything seems to be going well, you have obviously overlooked something.
7. Nature always sides with the hidden flaw.
8. Mother nature is a bitch.

Diprivan
MJ (Michael Jackson White Stuff Milk of Amnesia
Propofol
DIPRIVAN Injectable Emulsion is an intravenous sedative-hypnotic agent for use in the induction and maintenance of anesthesia or sedation. Intravenous injection of a therapeutic dose of Propofol induces hypnosis, with minimal excitation
Key things about Propofol
It is a cardiac depressent
Will cause apnea
Irritating to vessels when injected
Apnea and Hypotension
Etomidate
Etomidate is a short-acting hypnotic, which appears to have gamma-aminobutyric acid (GABA)–like effects. Unlike the barbiturates, etomidate reduces subcortical inhibition at the onset of hypnosis while inducing neocortical sleep
Etomidate
In a retrospective review of almost 32,000 people, etomidate, when used for the induction of anaesthesia, was associated 2.5-fold increase in the risk of dying than those given propofol
Why? Are we using Etomidate in sicker patients?
Key items about Etomidate
Less cardiac depressent
Adrenocortical suppression lasting 4-6 hours
May cause myoclonus
Irritable to vessels when injected
Ketamine
Ketamine is a rapid-acting general anesthetic producing an anesthetic state characterized by profound analgesia, normal pharyngeal-laryngeal reflexes, normal or slightly enhanced skeletal muscle tone, cardiovascular and respiratory stimulation, and occasionally a transient and minimal respiratory depression.
The anesthetic state produced by Ketamine has been termed “dissociative anesthesia” in that it appears to selectively interrupt association pathways of the brain before producing somesthetic sensory blockade.
Dissociative Anesthesia
Loss of some types of sensation with persistence of others. A loss of sensation for pain and temperature occurs without loss of tactile sense
Ketmamine Side effects]
Cardiovascular: Arrythmias, bradycardia or tachycardia, hyper- or hypotension
Central nervous system: Ketamine is traditionally avoided in people with or at risk of intrcranial pressure (ICP) due to concerns about ketamine causing increased intracranial pressure. It does not increase ICP more than opioids.
Gastrointestinal: Anorexia, nausea, increased salivation, vomiting
Local: Pain or exanthema of the injection site Neuromuscular and skeletal: Increased skeletal muscle tone
(tonic-clonic movements) Ocular: Diplopia, increased intraocular pressure, nystagmus Respiratory: Airway obstruction, apnea, increased bronchial
secretions, respiratory depression, laryngospasm Other: Anaphylaxis, dependence, emergence reaction

Rapid-onset short-acting barbiturate general anesthetic that is an analogue of Thiobarbital

March was named for the Roman God "Mars
Stages of Anesthesia
Stage I--Analgesia. This stage lasts from the beginning of the administration of anesthesia to the beginning of the loss of consciousness.
Stage II--Excitement. This stage lasts from the loss of consciousness to the loss of the eyelid reflex (which marks the beginning of surgical anesthesia).
Stage III--Surgical Anesthesia. Most operations are performed at this stage of anesthesia, which begins following the excitement stage.
Stage IV--Medullary Paralysis. This stage begins when the anesthetic depresses the medulla.
Stages of Anesthesia

Be prepared Have a mental backup plan Know your rescue plan of action Don’t be afraid to ask for help If needed, say ‘Uncle’ **Stay Calm**

Be Prepared Be Vigilant Expect the unexpected at anytime
Patient Safety is #1 Goal Patient satisfaction
In Summary
Each and Every Patient is Different in their own way
Know your patient Know what you are administering Be Prepared Be Vigilant Plan B? ALWAYS remember– You can give more,
but you can’t take away what you have given
