Colloid osmometry

Complications related to intravascular fluid resuscitation and maintenance can become life-threatening. Overhydration and underhydration can lead to significant perfusion abnormalities and can delay or prevent recovery. A working knowledge of transcapillary fluid dynamics gives the veterinarian the basis for evaluating the cause of alterations that make up Starling's forces. By combining this knowledge with patient assessment and laboratory diagnostics, the veterinarian can make a logical decision about the best treatment to correct the Starling's force alteration. Colloid osmometry is a particularly useful tool for assessing a patient's colloid osmotic pressure. It allows the veterinarian to distinguish between reduced oncotic pressure and increased hydrostatic pressure as a cause for intravascular fluid loss or edema formation.
