Examples of Isotonic Solutions
(What is Isotonic to plasma?) |
-Lactated Ringers
-0.9% NaCl (Normal Saline) -D5% in H20 (until glucose is metabolized then it becomes hypotonic) -Sodium Lactate Solution Average Serum Osmolality is 290 mOsm/Kg. Isotonic fluids are 240-340. |
|
|
When are Isotonic Solutions used?
|
Hypovolemia (blood chemistry ok).
Burns, fluid loss, diarrhea, etc. |
|
|
Examples of Hypotonic Solutions
|
-0.45% NaCl
-0.33% NaCl -D5% in H20 AFTER it becomes metabolized! |
|
|
When are Hypotonic Solutions used?
|
Dehydration where electrolytes are still high and you want to supply free water and dilute electrolytes.

|
Examples of Hypertonic Solutions
|
-3% NaCl (used for severe hyponatremia)
-5% NaCl (dangerous) -5% Sodium Bicarb (used to correct severe metabolic acidosis) |
|
|
When are Hypertonic Solutions used?
|
Patients who need electrolytes either for deficit or to regain acid base balance.
