pulmonary congestion (Too much fluid in lungs)
Administering large amount of IV fluid can cause pulmonary congestion as fluid shifts into the lungs
- In severe case, it may cause pulmonary edema, the collection of fluid within the small alveoli of the lungs
Brain Overload
-The brain is very sensitive to rapid changes in sodium and water balance
-Severe fluid overload can cause neurological changes because the brain cells become overly saturated with water
-This overstimulation of water present the normal electrical impulses from efficiently transmitting signals, which can cause neurological changes such as
NAUSEA
CONFUSION
LETHARGY
SEIZURES
COMA EVEN DEATH
Normal saline
A mixture of salt and water. It is called normal because its salt concentration is similar to tears, blood and other body fluids
Ringers Lactate (like drinking a gatorade)
Contains additives including calcium, potassium, lactate, sodium, and chloride. Used to replace fluid lost by the body. It is commonly used for fluid resuscitation, meaning that the patient needs aggressive fluid replacement for blood loss or illness
5% Dextrose
Dextrose is a form of glucose, sugar. Dextrose 5% in water replaces lost fluids and provides carbohydrates to the body. Used to treat low blood sugar (hypoglycemia), insulin shock, or dehydration, fluid loss
