Third spacing is an outdated term describing the movement of bodily fluid from the blood, into the spaces between the cells. The term “third spacing” also describes the accumulation of fluid from the blood within body cavities, intestinal areas, or areas of the body that normally contain little fluid.

What is an example of third spacing?
Any condition that destroys tissue or reduces protein intake can lead to protein losses and third-spacing. Some examples are hypocalcemia, decreased iron intake, severe liver diseases, alcoholism, hypothyroidism, malabsorption, malnutrition, renal disease, diarrhea, immobility, burns, and cancer.
What is the difference between 3rd spacing and edema?
Edema may form which is an abnormal accumulation of fluid in the interstitium; and “third spacing” which refers to an abnormal accumulation of fluid within body tissue or a body cavity may occur.
Where does the fluid go in third spacing?
In third-spacing, fluid in the body moves from the
intravascular spaces to the extravascular spaces. b. extravascular spaces to the intracellular spaces.
What is second spacing?
2nd spacing: Refers to abnormal fluid accumulating in interstitial spaces.Basically, this fluid is in a place in the body where it is difficult or impossible for it to move back into the cells or blood vessels without medical intervention.
Who is at risk for third spacing?
Any condition that destroys tissue or reduces protein intake can lead to protein losses and third-spacing. Some examples are hypocalcemia, decreased iron intake, severe liver diseases, alcoholism, hypothyroidism, malabsorption, malnutrition, renal disease, diarrhea, immobility, burns, and cancer.
What is the interstitial space?
The Interstitium. The interstitial space that lies between blood vessels and cells provides the fluid and structural environment surrounding those cells. Under most conditions in most tissues, fluid from the vascular space continually filters from the microvessels into the interstitial space and is not reabsorbed (1).
Is ascites third spacing?
Extensive tissue swelling occurs when the third space fills with excess fluid, known as edema. An example of severe third spacing is ascites, as seen in severe liver failure as a result of a low albumin level in the circulating blood.
How does third spacing cause hyponatremia?
Third space distribution of fluid is the key factor in the mechanism of hyponatremia due to nephrotic syndrome. Because of the low serum protein, oncotic pressure is reduced and fluid migrates out of the intravascular compartment, reducing the effective circulating volume.
Is compartment syndrome third spacing?
Intra-abdominal hypertension and abdominal compartment syndrome are deadly complications of third spacing and capillary leak that occur secondary to excessive fluid resuscitation.
Can Hypoalbuminemia cause third spacing?
Hypoalbuminemia (generally defined as a serum albumin concentration ≤30 g/l) [5,30] is very common in critically ill patients, the main reasons probably being increased albumin losses from bleeding and via the gastrointestinal tract [31], increased capillary permeability leading to a redistribution from the
What’s edema?
Edema is swelling caused by excess fluid trapped in your body’s tissues. Although edema can affect any part of your body, you may notice it more in your hands, arms, feet, ankles and legs.
Why do burns cause third spacing?
A subsequent increase in vascular permeability occurs secondary to both direct thermal injury and the release of vasoactive substances. This capillary leak produces burn edema as well as “third spacing,” a phenomenon characterized by large fluid and protein shifts between the vascular and interstitial spaces.
Does the third space exist?
Transcellular compartment (Third Space)
Examples of transcellular spaces include the eye, the central nervous system, and the peritoneal and pleural cavities. A small amount of fluid does exist normally in such spaces.
What are the three fluid spaces?
There are three major fluid compartments; intravascular, interstitial, and intracellular. Fluid movement from the intravascular to interstitial and intracellular compartments occurs in the capillaries.
What makes up the intravascular space?
Intravascular Compartment
The main intravascular fluid in mammals is blood, a complex fluid with elements of a suspension (blood cells), colloid (globulins) and solutes (glucose and ions). The average volume of plasma in the average (70 kg) male is approximately 3.5 liters.
How do I stop third spacing?
The best treatment for third spacing usually depends on the underlying cause and phase of the condition. Managing phase 1 typically includes administering intravenous fluids, often crystalloid or colloid fluid.
How can you tell if someone is hypovolemic?
Other signs of hypovolemic shock include:
- Rapid heartbeat.
- Quick, shallow breathing.
- Feeling weak.
- Being tired.
- Confusion or wooziness.
- Having little or no pee.
- Low blood pressure.
- Cool, clammy skin.
What is fluid shifting?
Translocation of body fluids from one compartment to another, such as from the vascular to the interstitial compartments. Fluid shifts are associated with profound changes in vascular permeability and WATER-ELECTROLYTE IMBALANCE.

What is the space between organs called?
Interstitium. Anatomical terminology. The interstitium is a contiguous fluid-filled space existing between a structural barrier, such as a cell wall or the skin, and internal structures, such as organs, including muscles and the circulatory system.
