“Also, remember that dextrose gets almost immediately metabolized to water and CO2 when it enters the circulation so it is not osmotically active for too long.”. When it comes to IV fluids, there are a few basic scenarios.
Can you take PO for elective reasons?
Also, patients who are healthy, can take po, and are admitted for an elective reason don’t need fluids. Pre-procedure or NPO patient who is euvolemic: treat this patient like a surgical patient if the patient is going to be NPO for longer than 6-12 hours. Give D51⁄2 NS.
Why does urine output decrease?
As a result, urine output is decreased. When blood is “thicker,” the heart has to work harder, causing the pulse to increase in order to maintain blood pressure. All of these compensatory actions by the body put an already-compromised patient at risk.
What is IV therapy?
All nursing programs include fluid balance and intravenous (IV) therapy as part of the curriculum. The information about the types of IV solutions and when to use them can be confusing for a nursing student. Nurse.Plus is happy to offer this simple reference guide to the four basic types.
How does water move in cells?
Water will move from extracellular space into the cells. Hypertonic: When the extracellular fluid has more solutes (osmolarity) than within the cells, water flows out of the cells. Isotonic: Both the extracellular and intracellular fluids have the same osmolarity, so there is no movement of water between them.
Where is water found in the body?
The rest is found in blood vessels and between the cells. Water makes up 73% of the brain and heart; 83% of the lungs; 79% of the muscles and kidneys; and 64% of the skin. Water is essential to every living cell. Some of its functions: Necessary for cellular metabolism and building materials.
Is saline a sterile fluid?
It is a sterile, nonpyrogenic crystalloid fluid administered via an intravenous solution. Normal saline infusion is used for extracellular fluid replacement (e.g., dehydration, hypovolemia, hemorrhage, sepsis), treatment of metabolic alkalosis in the presence of fluid loss, and for mild sodium depletion.
What happens when fluid is lost?
Joint lubrication. When fluid is lost for any reason, electrolytes become imbalanced, body systems are stressed, and cognitive function in the brain is impaired. Blood becomes concentrated, signaling the kidneys to retain water. As a result, urine output is decreased.
Can you give saline solution via IV?
Normal saline solution can be administered only via intravenous (IV) access. 0.9% Normal Saline (NS, 0.9NaCl, or NSS) is one of the most common IV fluids, it is administered for most hydration needs: hemorrhage, vomiting, diarrhea, hemorrhage, drainage from GI suction, metabolic acidosis, or shock. It is an isotonic crystalloid ...
Why are skin and lung losses increased?
Lung losses are increased due to tachypnea or a tracheostomy.
What are maintenance fluids?
Maintenance fluids consist of water, glucose, sodium, and potassium. The glucose prevents starvation ketoacidosis and decreases the likelihood of hypoglycemia. Water, sodium and potassium protect the patient from dehydration and electrolyte disorders.
How long does it take for a patient to rehydrate?
This is followed by a plan for rehydrating the patient, typically over 24 hours. In addition, many patients in the ICU have intravascular volume depletion due to other mechanisms (e.g. capillary leak). These patients often require fluid resuscitation but may also benefit from other interventions (pressors).
Do ICU patients need intravenous fluids?
What every clinician needs to know. The majority of children in an ICU receive intravenous fluids, especially during their initial course. Enteral feeds are the ultimate goal, but may be precluded due to specific contraindications (e.g. abdominal surgery, respiratory distress). Patients who are NPO require “maintenance” fluids, ...
What is the standard dextrose composition of maintenance fluids?
It is prudent to monitor the sodium concentration at least daily in an ICU patient to detect increases or decreases in the serum sodium concentration and then adjust the rate or composition of the maintenance fluid, depending on the clinical situation. D5 is the standard dextrose composition of maintenance fluids.
How long does it take to give a child a bolus?
A bolus is 20 ml/kg (maximum 1 liter). This is typically given over 20 minutes in the child with moderate dehydration and as fast as possible in the child with severe dehydration.
Can hypotonic fluid cause iatrogenic hyponatremia?
However, the use of hypotonic fluids has been associated with iatrogenic hyponatremia in children. This is thought to be secondary to the multiple stimuli for ADH production in the hospitalized child (e.g. volume depletion, pain, nausea, medications).
What is the osmolality of hypotonic solutions?
Hypotonic solutions have an osmol ality of less than 240 mOsm/liter. They exert less osmotic pressure than the fluid in the extracellular compartment which allows water to be drawn from the extracellular fluid. Blood cells will draw these solutions into them causing the blood cells to swell and burst.
How much sodium is in Hartmann's solution?

What are the complications of lactate infusion?
Complications connected with the infusion of LR (Lactated Ringers) are overhydration, electrolyte excess (particularly sodium), electrolyte dilution, and calorie depletion.
Is D5 1/2 NS hypotonic?
While D5 1/2 NS is hypertonic in the bag, upon intra venous administration it becomes hypotonic- because the body absorbs the glucose (almost immediatelt) leaving only 1/2 NS being absorbed into the vascular space. If this fluid is given inappropriately, it can lead to the swelling and lysis of cells.
What is isotonic solution?
Isotonic solutions have the same tonicity as plasma so that when they are infused into a vein, water neither enters or leaves the cells. These kinds of IV solutions are used to expand the extracellular fluid volume and do not cause any fluid to move from into or out of the blood cells.
Can LR be used for liver disease?
Patient can also develop metabolic alkalosis if LR is run over long periods of time. It shouldn't be used in patients with liver disease because the lactate is metabolized in the liver. You will commonly see LR used for surgical patients. Adding 5% dextrose to LR makes the solution hypertonic.
