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.

Propofol

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

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.
