Crystalloids are aqueous (water-based) solutions of mineral and other water soluble salts. They are used in intravenous fluid replacement to replace lost water and electrolytes due to dehydration, to support blood pressure, and, in some cases, to replace blood volume in circumstances of shock or blood loss.
Crystalloids are used to replace lost water and electrolytes due to dehydration, to support blood pressure, and, in some cases, to replace blood volume in circumstances of shock or blood loss following surgery or injury.
Dosage and Administration
|IV or SQ||Based on body-weight and degree of fluid replacement needed||Dependent on specific crystalloid used||Treatment||As needed|
Leakage of crystalloids around the vein (i.e. from a poorly-placed or dislodged IV catheter) may cause irritation. Inflammation and/or infection of the vein are known risks of IV catheter placement. Inappropriate crystalloid selection may cause electrolyte imbalances.
Intravenous or subcutaneous administration of crystalloid solutions must be done with strict attention to proper sterile technique.
Dosage should be calculated and monitored by a licensed veterinarian.
Certain drugs (i.e. flunixin meglumine) will form precipitates when mixed with particular crystalloids such as Lactated Ringer's solution. Addition of medications to IV crystalloid fluid solutions should not be performed except under the direct supervision of a licensed veterinarian..
Excessive IV fluid therapy can cause symptoms of volume overload, including pleural effusion (build-up of fluid in the chest cavity). Smaller animals are particularly vulnerable. Dosing should be calculated and monitored by a veterinarian
