Which of the following does not represent a significant anesthetic problem in the morbidly, obese patient:
|A||Difficulties in endotracheal intubation|
|B||Suboptimal arterial oxygen tension|
|C||Increased metabolism of volatile agents|
|D||Decreased cardiac output relative to total body|
Decreased cardiac output relative to total body
a. Cardiac output increases by 100 ml/kg of adipose tissue.
b. Therefore, obese patients are in high output state (so develop LVH).
c. Volatile anaesthetics are more extensively metabolized in obese patients (so at higher risk of halothane hepatitis and methoxyflurane induced nephro- I toxicity).
