Is phenobarbital used for general anesthesia?
|
no it is used for seizures
duration of action is 6-12 hours |
|
|
What are the CNS effects of barbiturates?
|
Depression
GABA receptors no analgesia causes increased heart rate and decreased blood pressure |
|
|

|
redistribution
|
|
|
Ketamine and tiletamine are examples of what type of anesthetic agent?
