What is the difference between fluid resuscitation crystalloids and colloids?
Home > UCSF Hospitalist Handbook > 04. Critical Care > 13. Fluid Resuscitation 13. Fluid Resuscitation Crystalloids: IV fluids composed of water and electrolytes. Colloids: IV fluids composed with larger macromolecules or particles that are relatively membrane-impermeable (e.g., albumin, red blood cell substitutes, Hextend/hetastarch).
What is the most commonly used crystalloid fluid?
While normal saline (0.9% NaCl solution) is the most frequently used crystalloid fluid, many other formulations can provide improved clinical outcomes in specific patient populations. Other commercially available crystalloid fluids include: Lactated Ringer's/Hartman's solution (lactate buffered solution)
Which crystalloid is preferred over NS resuscitation?
Balanced fluids (LR or Plasma-Lyte) are the preferred crystalloid over NS given reduced mortality and RRT. After initial fluid resuscitation, additional fluid needs are determined based on clinical response using capillary refill rate, BP response, PPV, UOP and other dynamic assessments of fluid responsiveness.
What is a colloid solution?
Colloid solutions are suspensions of molecules within a carrier solution that are relatively incapable of crossing the healthy semipermeable capillary membrane owing to the molecular weight of the molecules.
