Regional gastric flow determined by a hydrogen clearance technique in anesthetized and conscious animals.

Gastric microcirculatory studies were performed by a hydrogen clearance technique in anesthetized and conscious cats. The highest flow values were observed in the mucosa, while submucosal flow was higher than muscularis flow. During anesthesia antral blood perfusion exceeded corpus perfusion, but this relationship was reversed in favor of the corpus region in conscious animals.
