What is splanchnic vasodilation?

Splanchnic vasodilation is responsible for the hypoperfusion of the renal system which leads to the activation of the renin-angiotensin-aldosterone system and to fluid retention. Diuretics are the pivotal drugs in the control of ascites.

What is splanchnic Haematoma?

The splanchnic circulation may be defined as that part of the circulation which, in the normal animal, opens into the inferior vena cava by way of the hepatic veins. The changes which may occur in this system after haemorrhage may be subdivided as follows: Changes in total splanchnic blood flow.

What is splanchnic ischemia?

Abstract. Chronic splanchnic ischaemia is a relatively unusual clinical entity consisting of pain and/or weight loss and caused by chronic splanchnic disease (i.e. stenosis and/or occlusion of the coeliac and superior mesenteric artery).

Why does splanchnic vasodilation occur?

An increased production or activation of vasodilatory mediators and systems, and a decreased vascular reactivity to vasoconstrictors (Figure 1), are probably responsible for this splanchnic hyperaemia (vasodilation).

The portal vein is a blood vessel that delivers blood to the liver from the stomach, intestines, spleen, and pancreas. Most of the liver’s blood supply is delivered by the portal vein.

What is splanchnic hypoperfusion?

INTRODUCTION. Splanchnic hypoperfusion is commonly found in critically ill patients, which are: trauma, sepsis, burn wound. Hypoperfusion may cause ischemia of the mucosa, disturbance of gut barrier, and splanchnic permeability increased, which may further induce bacterial translocation.

What is throm?

Thrombosis is the formation of a blood clot, known as a thrombus, within a blood vessel. It prevents blood from flowing normally through the circulatory system. Blood clotting, also known as coagulation, is the body’s first line of defense against bleeding.

How does splanchnic blood flow affect drug absorption?

A relatively small change in absorption rate occurred when the splanchnic blood flow rate was decreased about 35%. Further reductions in mesenteric blood flow resulted in progressive impairment of sulfaethidole absorption.

What do pelvic splanchnic nerves innervate?

The pelvic splanchnic nerves contribute to the innervation of the pelvic and genital organs. The nerves regulate the emptying of the urinary bladder, control opening and closing of the internal urethral sphincter, influence motility in the rectum as well as sexual functions like erection.
