|

beginning - breath in drugs, warmth, detachment felt, may hear ringing in ears, loss of motor control, sounds are amplified. |
|
Stage 2 of General Anesthesia |
Excitement - patient struggles, sings, shouts, talks, cries, can be avoided if drugs are given quickly and smoothly. |
|
Stage 3 of General Anesthesia |
surgical anesthesia: reached by continued use of vapor/gas. Pupils are small and contract in light, respirations are normal, pulse volume/rate are normal, skin is slightly flushed. With proper drug use this state can be maintained for hours at four ranges light (1) to deep (4) |
|
