Change in portal venous blood flow alters hepatic arterial resistance upstream from the site of a constant arterial back pressure.
Low-dose dopamine in patients with early renal dysfunction: The effects of dopamine and adrenaline infusions on acid-base balance and systemic haemodynamics in severe infection. Overall organ perfusion was sufficient in both groups because none of the patients demonstrated an increase in blood lactate concentration. Jejunal mucosal perfusion is well-maintained during mild hypothermic cardiopulmonary bypass in humans. Once detected, the treatment of splanchnic ischaemia is not straightforward [ 10 ].
This is contrary to the expectation that the liver may be the initial victim if gut derived bacteria or endotoxins were carried in the portal blood.
Thoracoscopic splanchnic denervation TSD for chronic pancreatitis pain resulted in fewer patients on opioids and overall increases in pain thresholds. Volatile anaesthetic agents have well recognized effects on systemic haemodynamics, but may also cause regional changes in blood flow to the splanchnic circulation.
In Sprague Dawley rats, celiac ganglionectomy CGX through surgical removal of the celiac ganglionic plexus was performed with consequent significant reduction of the norepinephrine concentrations in the entire splanchnic area and the mesenteric vessels. The splanchnic vascular bed demonstrates an autoregulatory capacity similar to that seen in other vascular beds such as the renal and cerebral circulations.

Whether this drug also exerts its beneficial effects under clinical conditions of low splanchnic blood flow has yet to be demonstrated. Gastric tonometers were used to assess the adequacy of mucosal perfusion, and arterial lactate was measured in order to assess the overall adequacy of oxygen delivery.
Its effects on splanchnic perfusion appear to be minimal.Sympathetic Nervous System Anatomy - Part 1
Assessment of the adequacy of systemic and regional perfusion after cardiac surgery. Evaluation of the splanchnic microcirculation is complicated by the inability to directly measure blood flow and oxygenation in human disease.
