This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: General anaesthesia, Subject name: Anaesthesia
All are true regarding Xenon anesthesia except 
Select and explain. 
A. Slow induction and recovery, B. Non explosive, C. Minimal cardiovascular side-effects, D. Low blood solubility
A: Slow induction and recovery
Answer: A: Slow induction and recovery 
Explanation: Xenon is a "noble" gas that has long been known to have anesthetic propeies. It is an ine element that does not form chemical bonds. It is an odorless, nonexplosive, naturally occurring gas with a MAC of .71 and a blood/gas coefficient of 0.115, giving it very fast onset and emergence parameters. Xenon's anesthetic effects seem to be mediated by NMDA inhibition by competing with glycine at the glycine binding site. Xenon seems to have little effect on cardiovascular, hepatic, or renal systems and has been found to be protective against neuronal ischemia. Cost and limited availability have prevented its widespread use. Advantages Ine (probably nontoxic with no metabolism) Minimal cardiovascular effects Low blood solubility Rapid induction and recovery Does not trigger malignant hypehermia Environmentally friendly Nonexplosive Disadvantages High cost Low potency (MAC = 70%) Morgan clinical anesthesia 5e pg: 173
