anaestheiology Flashcards
anesthesia was derived from-
greek anaisthaesia
freedom from pain -
analgesia
behavioral changes where anxiety is relieved and the patient becomes relaxed and the patient is aware of their surrounding-
tranqilization
central depression + drowsiness and unaware of the surrounding
sedation
drugs that induces a state of sleep
narcosis
artificially induced sleep or tranqresembling sleep-
hypnosis
loss of sensation in circumscribed area
LA
example of regional anesthesia
Paralumbar nerve block
define GA
drug induced loss of consciousness that is characterized by reversible loss of consciousness and analgesia.In this state the patient cannot be aroused from notius stimuation. the sensory,motor and autonomous reflex functions are attenuated
state or plane GA where there is unconsciousness+muscle relaxation+analgesia
surgical anesthesia
the state of anaesthisia indused by multiple drugs
balanced anaesthesia
what is dissociative anesthesia
drugs that dissociate the thalamocortic and limbic system(ketamin) and it is characterised by cataleptoid state
state of waxy flexibility is -
catalepsy

types (classification )anesthesia

what are the general consideration for administration of anesthesia
- species
- age

- dieseas condition
factors influencing the selection of anesthetic technique
- size

- biochemical test
(TPP,SGPT,HG,CREATININE)
what are the categories of patient in regards to physical status -
category 1
healthy patient with no systemic diseases
category 2
slight or mild systemic diseases with cs
category 3

category 5
morbid or dying patients
