Study Notes

Crystalloids vs Colloids in Restoring Intravascular Volume

Crystalloids are equally effective as colloids in restoring intravascular volume when given in sufficient amounts.
When using colloids, the volume needed to replace an intravascular volume deficit is typically 3-4 times less than with crystalloids.
Colloid solutions can rapidly correct severe intravascular fluid deficits more efficiently.

Risks of Rapid Administration of Large Amounts of Crystalloids

Rapid administration of large amounts of crystalloids (>4-5L) is associated with a higher frequency of tissue edema.
Marked tissue edema can impair oxygen transport, tissue healing, and return of bowel function following major surgery.
