| what is BALANCED ANESTHESIA? |
|
Definition
| mixing of several drugs in smaller amounts to achieve desired level of effects without the adverse effects of a single drug |
|
|
Term
| general effects of anesthesia on RESPIRATION and BODY TEMPERATURE |
|
Definition
depressed respiration
hypothermia |
|
|
Term
|
Definition
MINIMAL ALVEOLAR CONCENTRATION needed to prevent movement in 50% of patients
**this is ADDITIVE |
|
|
Term
|
Definition
-thiopental
-propofol
-ketamine
-etomidate |
|
|
Term
|
Definition
-fast acting
-lipophilic
-lowers CNS blood flow, BP, and respiration
-raises HR |
|
|
Term
|
Definition
-most common IV anesthetic
-short acting
-lipophilic
-lowers CNS blood flow, BP, and respiration
***advantage is that it has LITTLE NAUSEATING EFFECT*** |
|
|
Term
|
Definition
***CVS STABILITY- good for hypotensives
***inhibits adrenocortical stress (CORTISOL) response |

Term
| what are the INHALATIONAL ANESTHETICS? other facts? |
|
Definition
-Halothane
-Isoflurane
-Enflurane
-Desflurane
-Sevoflurane
-Nitrous oxide
**low therapeutic index** |
|
|
Term
| what is PARTITION COEFFICIENT |
|
Definition
RATIO of anesthetic concentration in two tissues AT THE SAME PARTIAL PRESSURE
(i.e. less soluble drugs means less needs to go into the blood to reach equal partial pressure) |
|
|
Term
|
Definition
-not used often
-low MAC, high partition coefficient
***can cause MALIGNANT HYPERTHERMIA*** due to excess Ca2+ release from sarc. reticulum |
|
|
Term
|
Definition
-pungent odor
***used in NEUROSURGERY*** because decreases cerebral vasodilation and O2 consumption-unlike all other INHALATIONAL ANESTHETICS in that way |
|
|
Term
|
Definition
| more side effects than ISOFLURANE |
|
|
Term
|
Definition
very pungent
***CI in ASTHMATICS** |
|
|
Term
|
Definition
-NOT pungent
**no TACHYCARDIA** |
|
|
Term
|
Definition
-MAC>100
-used in DENTAL PROCEDURES
-causes nausea and vomitting
***causes expansion of air filled cavities***--> CI in patients with pneumothorax, or air in GI, etc. |
