muscle protein loss
what does ERAS stand for? Correct Answer-Enhanced Recovery After
Surgery

of different drug classes rather than a single drug to produce anesthesia
- reduce total dose of one -> dec side effects
,Stages of General Anesthesia Correct Answer-induction, maintenance,
recovery

IV GA Correct Answer-propofol
midazolam
