|
Term
| So it turns out hiring an anethesiology off of craigs list was a bad idea. Your patient has just started to experience seizures. What general anesthetic do you think caused this? |
|

| This drug should not be used in Automatic Anethesia Machine Despenser Rhingies if the AAMDT uses dissicated CO2 absorbant. |
|
Definition
| Sevoflurane. It may cause airway burns |

|
Term
| Halothane can cause Malignant Hyperthermia. What is the treatment for this and what is its MOA? |
|
Definition
Dantrolene. It blocks calcium release from the sarcoplasmic reticulum.
Recall that Malignant Hyperthermia presents with hyperthermia, tachycardia, metabolic acidosis, hypercalcemia, muscle contraction and myoglobinura. |
|
|
Term
| An anethetic that has a 100% MAC and can cause diffusion hypoxia. |
|
