Shock reduction in circulatory volume due to loss of plasma

2021-04-30 08:13 PM

Hypo lytic shock due to plasma loss has features that closely resemble haemorrhagic shock, except for one other complex factor.

Loss of plasma from the circulatory system, even in the absence of erythrocytes, can sometimes be so severe that a marked decrease in total blood volume causes a typical hypovolemic shock in most limbs. secreted by haemorrhage. Severe plasma loss occurs in the following problems:

1. Intestinal obstruction can severely reduce plasma volume. The intestinal obstruction partially obstructs the venous blood flow in the intestinal wall, increasing intestinal capillary pressure. This increase in pressure in turn causes fluid to leak from the capillaries into the intestinal wall and into the lumen. Since the fluid lost has a high protein content, the result is a decrease in the total amount of plasma proteins, as well as a decrease in the plasma volume.

2. Severe burns or other skin conditions cause the loss of plasma through the peeled skin areas, resulting in a marked decrease in plasma volume.

Hypo lytic shock due to plasma loss has characteristics that closely resemble haemorrhagic shock, with the exception of another complex factor: the viscosity of the blood increases greatly due to the increased concentration of red blood cells in the remaining blood, and This increases the viscosity which worsens the slowness of blood flow.

Dehydration from all of the body's fluid compartments is known as dehydration; This condition can also decrease blood volume and cause a hypovolemic shock similar to that caused by a haemorrhage. Some causes of this shock are (1) excessive sweating, (2) fluid loss during severe diarrhoea or vomiting, (3) excessive kidney loss, (4) insufficient intake of fluids and fluids. electrolytes, or (5) damage the adrenal cortex, loss of aldosterone secretion and as a result, the kidneys fail to reabsorb sodium, chloride, and water, which occurs in the absence of aldosterone cortex hormone.



Pathophysiology of cardiogenic shock

Urine formation: Reabsorbed glomerular filtration

Air in and out of the lungs: pressure causes the movement of air

Mechanism of urine concentration: osmotic pressure changes in different segments of the renal tubule

Absorption and excretion of potassium through the kidneys

Nephron: The functional unit of the kidney

Prothrombin activation: initiates blood clotting

Estimated renal plasma flow: PAH clearance

Pulmonary capillary dynamics: capillary fluid exchange and pulmonary interstitial fluid dynamics

Calculate the glomerular filtration rate (GFR): the forces that cause the filtration process

Red blood cells: differentiation and synthesis

Ammonia buffering system: excretes excess H + and creates new HCO3

Concentrated urine formation: urea contributes to increased osmotic pressure in the renal medullary

Reduced sodium chloride, dilates arterioles, increases Renin release.
