Colloids contain larger insoluble molecules, such as gelatin; blood itself is a colloid. There is no evidence that colloids are better than crystalloids in those who have had trauma, burns, or surgery. Colloids are more expensive than crystalloids. As such, colloids are not recommended for volume expansion in these settings. [2]
Crystalloid fluid resuscitation is preferred over colloid solutions for severe volume depletion not due to bleeding. The type of crystalloid used to resuscitate the patient can be individualized based on the patients' chemistries, estimated volume of resuscitation, acid/base status, and physician or institutional preferences.
A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid , [ 1 ] while others extend the definition to include substances like aerosols and gels .
TCCC promotes the early and far forward use of blood and blood products if available over the use colloids and discourages the administration of crystalloids such as normal saline (sodium chloride). Hypothermia prevention is an early and critical intervention to keep a traumatized casualty warm regardless of the operational environment.
Colloids and crystalloids appear to be equally effective with respect to outcomes., [31] Balanced crystalloids and normal saline also appear to be equally effective in critically ill patients. [32] If the person remains in shock after initial resuscitation, packed red blood cells should be administered to keep the hemoglobin greater than 100 g ...
Gelofusine is a volume expander that is used as a blood plasma replacement if a significant amount of blood is lost due to extreme hemorrhaging, trauma, dehydration, or a similar event. [1] Gelofusine is a 4% w/v solution of succinylated gelatine (also known as modified fluid gelatine) used as an intravenous colloid , and behaves much like ...
Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
Hydroxyethyl starch (HES/HAES), sold under the brand name Voluven among others, is a nonionic starch derivative, used as a volume expander in intravenous therapy.The use of HES on critically ill patients is associated with an increased risk of death and kidney problems.
