Isotonic
Hypotonic
Hypertonic
Colloid
Hypotonic
Hypotonic solutions like 0.45% NaCl have lower solute concentrations than body fluids, causing cells to swell as water moves into them through osmosis.
Hypovolemic shock
Acute blood loss
Acute kidney injury with hyperkalemia
Metabolic acidosis
Acute kidney injury with hyperkalemia
LR contains potassium, which could worsen hyperkalemia in patients with kidney injury. The potassium content is approximately 4 mEq/L.
0.45% Sodium Chloride
5% Dextrose in Water (D5W)
3% Sodium Chloride
0.225% Sodium Chloride
3% Sodium Chloride
3% Sodium Chloride is hypertonic and creates an osmotic gradient that pulls fluid from brain tissue into blood vessels, reducing cerebral edema and ICP.
Hypotension
Crackles upon lung auscultation
Flat neck veins
Increased urine output
Crackles upon lung auscultation
Crackles (rales) are an early sign of pulmonary edema, which can occur from fluid overload during rapid IV infusion.
Hypotonic
Isotonic
Hypertonic
Buffer
Hypertonic
D5NS is hypertonic because it contains both normal saline (0.9% NaCl) and 5% dextrose, making its total osmolarity higher than body fluids.
It is hypertonic in the bag and remains hypertonic in the body
It is isotonic in the bag but becomes hypotonic once metabolized
It is the preferred fluid for resuscitation in hypovolemic shock
It contains essential electrolytes like potassium and calcium
It is isotonic in the bag but becomes hypotonic once metabolized
D5W is initially isotonic but becomes hypotonic as the body rapidly metabolizes the dextrose, leaving only free water behind.
Lactated Ringer's
0.45% Sodium Chloride
0.9% Sodium Chloride
5% Dextrose in Water
0.9% Sodium Chloride
Normal saline (0.9% NaCl) is the only solution compatible with blood products as it won't cause hemolysis or clotting of red blood cells.
3% Sodium Chloride
0.45% Sodium Chloride
0.9% Sodium Chloride
10% Dextrose in Water
0.45% Sodium Chloride
Hypotonic solutions like 0.45% NaCl help correct hypernatremia by providing free water to dilute the elevated sodium levels.
Fluid resuscitation in trauma
Correcting severe dehydration in infants
Providing calories and treating hypoglycemia
Expanding the intravascular volume
Providing calories and treating hypoglycemia
D10W provides 10g of glucose per 100mL, making it an effective treatment for hypoglycemia while also providing caloric support.
0.45% Sodium Chloride
5% Dextrose in 0.45% Sodium Chloride
3% Sodium Chloride
0.225% Sodium Chloride
3% Sodium Chloride
Hypertonic solutions like 3% NaCl rapidly pull fluid into the intravascular space, increasing the risk of fluid overload in heart failure patients.
