Objective: To study the effects of moderate acute normovolemic hemodilution on the intestinal blood perfusion and oxygen supply in cats.
Methods: 15 domestic male cats were hemodiluted with Haemaccel. HR, MAP, lactate concentration in superior mesenteric vein (LAC), superior mesenteric artery blood flow (SMABF), superior mesenteric artery and venous blood gas analysis were recorded and the intestinal oxygen delivery (DO(2)), oxygen consumption (VO(2)) and oxygen extraction (EO(2)) were calculated before and after hemodilution.
Results: SMABF increased obviously (P < 0.05), intestinal DO(2) and EO(2) did not change (P > 0.05) but VO(2) increased (P < 0.05), and LAC in superior mesenteric vein did not increase.
Conclusions: Moderate acute normovolemic hemodilution with Haemaccel do not alter intestinal oxygen delivery by increasing the superior mesenteric blood flow. It means that intestinal mucosa ischemia does not happen during moderate acute normovolemic hemodilution.
