VTI Anesthesia I
Inhalents
| Question | Answer |
|---|---|
| Things we would like... | A rapid recovery and induction, having to use very little inhalant, safety. |
| Most likely to cause cardiac arrhythmia in dogs.. | Halothane |
| Biotransformed at 0.2% | Isoflurane |
| Biotransformed at 2-5% | Either |
| Very low biotransformation of 0.02% | Desflurane |
| Biotransformation is high at 20 - 46% | Halothane |
| Can't be used alone, as this is just an analgesic | Nitrous Oxide |
| Outdated, but had some desirable effects | Ether |
| Never used if intestinal obstruction, diaphragmatic hernia or pneumothorax is evident | Nitrous Oxide |
| Use of this will decrease the amout of inhalant anesthetic used | Nitrous Oxide |
| Can't be used with closed systems or low O2 flow rates | Nitrous Oxide |
| Has a preservative called thymol | Halothane |
| Diffusion hypoxia is a concern with this analgesic inhalant | Nitrous Oxide |
| Known for rapid induction, smooth recovery and nonpugent oder | Ether |
| The carrier gas | Oxygen |
| This is in blue cylinders | Nitrous Oxide |
| This is in green cylinders | Oxygen |
| Not commonly used in veterinary medicine due to adverse effects | Desflurane |
| The best inhalant for sick patients | Isoflurane |
| This must be delivered at no more than 70% | Nitrous Oxide |
| Can be used with non-precision vaporizer | Methoxyflurane |
| Masking animals is reserved for _____/______ patients | Calm/Docile |
| Inhalants are primarily eliminated from the body via.... | the respiratory system but some are bitransformed to greater extents than others |
| At normal concentrations, inhalants cause ... | hypotension, hypoventilation and decreases in cardiac output. |
| ____ ____ can be used as an adjunct along with inhalant anesthetics. | Nitrous Oxide(analgesic) |
| MAC | Minimum aveolar concentration |
| A measure of onset time for an inhalant | Solubility coefficent |
| A measure of how rapidly an agent evaporates | Vapor pressure |
| A measure of inhalant potency | MAC |
| This being a high number would make the agent highly volatile | Vapor pressure |
| This being a low number would result in a rapid induction and recovery | Solubility coefficent |
| This being a high number would result in a slow induction and recovery | Solubility coefficent |
| When this number is a low number, the inhalant is more potent | MAC |
| If this is a high number, the agent must be used with a precision vaporizer | Vapor pressure |
| If this number is high, it means that we will be using a large quantity of inhalant | MAC |
| Animals can be maintained at surgical levels with 1.5x this value | MAC |
| Toxic to rats | Sevo |
| sesitize the heart and is very bad in pigs | halothane |
| N20 full tank pressure is | 745 psi |
| O2 full tank pressure is | E-Tanks: 2200 PSI H-Tanks: 2200 PSI |
| 02 is the _____ gas | Carrier |
| Decreased S.C. is _____ and an increase is ______ | Good, Bad |
