The relationship between gastric blood flow and acid secretion has been studied by using a number of secretory stimulants and inhibitors and different techniques that measure gastric blood flow. Although there are conflicting data, there appears to be a consensus regarding the main aspects of this relationship. Agents that stimulate gastric acid secretion such as histamine, gastrin, cholinergic agents, and vagal stimulators also increase gastric blood flow. Other agents such as isoproterenol, epinephrine, and prostaglandins, which at low doses increase gastric blood flow, reduce gastric acid secretion at higher doses. Norepinephrine, vasopressin, and shock reduce gastric blood flow and thereby cause a decrease in secretion. Histamine H2-receptor antagonists reduce stimulated acid secretion and gastric blood flow. Histamine, gastrin, and acetylcholine have been shown to stimulate acid secretion in vitro. Therefore, these observations suggest that although blood flow is not a prerequisite for initiation of stimulated acid secretion, it can become rate-limiting at higher rates of secretion. Although the literature is replete with studies that attempt to characterize the relationship between gastric blood flow and acid secretion, conclusions have varied. Much of the difficulty has arisen because of the differences in technique used to measure gastric blood flow and the differences between anesthetized and unanesthetized animal preparations. Under some specific conditions, the different blood flow techniques give comparable results and this relationship can be defined.
