Term
| Which is safer, inhalation anesthetics or injectable anesthetics? |
|
Definition
|
|
Term
| Is toxicity something we should be concerned with when dealing with inhalation anesthetics? |
|
Definition
|
|
Term
| T/F...Inhalation anesthetics have minimal toxicity to patient AND personnel. |
|
Definition
|
|
Term
| T/F Administration is difficult, because of the many stages involved. |
|
Definition
|
|
Term
| Induction and recovery is known as...what? |
|
Definition
|
|
Term
| Can we control the anesthetic depth easily? |
|
Definition
|
|
Term
| What makes inhalent anesthetics an adequate post-op analgesia? |
|
Definition
| It has good muscle relaxation! |
|
|
Term
| T/F...is it okay to perform surgery while under inhalants? |
|
Definition
|
|
Term
| Is it cheap or expensive? |
|
Definition
| It's not cheap, but it's inexpensive. |
|
|
Term
| What are the 2 classes of inhalent agents? |
|
Definition
| Nitrous oxide, and halogenated compounds |
|
|
Term
| Give two examples of halogenated compounds. |
|
Definition
| Sevoflurane, and isoflurane |
|
|
Term
| Mechanism of action of inhalation agents, what's theory 1? |
|
Definition
| May inhibit breakdown of GABA in brain, the GABA is the gamma amino butyric acid - inhibitory neurotransmitter. |
|
|
Term
| Mechanism of action of inhalation agents, what's theory 2? |
|
Definition
| Lipid soluble anesthetic may dissolve in nerve cell membranes. the nerve cell loses the ability to conduct impulses. |
|
|
Term
| During induction, the patient inhales what? |
|
Definition
| A mixture of vaporized anesthetic agent and oxygen |
|
|
Term
| Where does the anesthetic mixture go to first? |
|
Definition
|
|
Term
| Where do the anesthetic molecules diffuse to once in the alveolar? |
|
Definition
| They diffuse across the cell membrane to the blood |
|
|
Term
| What is the rate of diffusion controlled by? |
|
Definition
| The concentration gradient of anesthetic agent between alveoli and blood. |
|
|
Term
| Where do those anesthetic molecules diffuse to once they're in the blood? |
|
Definition
|
|
Term
| What is the definition of maintenance? |
|
Definition
| As long as the inhaled concentration of the anesthetic agent maintains the proper alveolar, blood and brain concentration |
|
|
Term
| Basically, what does that mean? |
|
Definition
| The patient must *continue* to breathe the anesthetic so it stays where it needs to be |
|
|
Term
| During recovery what happens to concentration of the inhaled anesthetic agent? |
|
Definition
|
|
Term
| What happens to the alveolar levels of the anesthetic agent? |
|
Definition
|
|
Term
| During recovery, the agent is exhaled from the blood that's diffused to the alveoli, then what happens? |
|
Definition
| The blood levels of the anesthetic agent are decreased |
|
|
Term
| The anesthetic agent then does what? |
|
Definition
| Diffuses to the brain into the blood |
|
|
Term
| When the brain levels decrease, what starts happening? |
|
Definition
| the anesthetics lighten, and recovery occurs |
|
|
Term
| What is the definition of vapor pressure? |
|
Definition
| The amount of liquid anesthetic that will evaporate |
|
|
Term
| What degrees celsius will vapor pressure occur? |
|
Definition
|
|
Term
| The amount of liquid that will evaporate into that gas pocket is expressed as what? |
|
Definition
|
|
