Colloids are indicated for patients in malnourished states and patients who cannot tolerate large infusions of fluid. Human albumin is a solution derived from plasma. It is used to increase the circulating volume and restore protein levels in conditions such as burns , pancreatitis , and plasma loss through trauma. They are considered blood transfusion products and uses the same protocols and nursing precautions when administering albumin.
The use of albumin is contraindicated in patients with the following conditions: severe anemia , heart failure, or known sensitivity to albumin. Additionally, angiotensin-converting enzyme inhibitors should be withheld for at least 24 hours before administering albumin because of the risk of atypical reactions, such as hypotension and flushing. Dextrans are polysaccharides that act as colloids.
They are available in either saline or glucose solutions. LMWD contains polysaccharide molecules that behave like colloids with an average molecular weight of 40, Dextran LMWD is used to improve the microcirculation in patients with poor peripheral circulation. They contain no electrolytes and are used to treat shock related to vascular volume loss e.
On certain surgical procedures, LMWDs are used to prevent venous thromboembolism. They are contraindicated in patients with thrombocytopenia, hypofibrinogenemia, and hypersensitivity to dextran.
HMWD contains polysaccharide molecules with an average molecular weight of 70, Dextran 70 or 75, Dextran HMWD used for patients with hypovolemia and hypotension. They are contraindicated in patients with hemorrhagic shock. These solutions are derived from starch and are used to increase intravascular fluid but can interfere with normal coagulation. Gelatins have lower molecular weight than dextrans and therefore remain in the circulation for a shorter period of time. Plasma Protein Fraction is a solution that is also prepared from plasma, and like albumin, is heated before infusion.
It is recommended to infuse slowly to increase circulating volume. The following are the general nursing interventions and considerations when administering colloid IV solutions:. The following are the references and sources for this IV fluid guide that you may find interesting or if you want to further your reading:. It would be a very useful tool if this was also an app, it would make study and accessing material was easier and will attract more people to use the material :.
I can not leave this site without confessing myself. Also a special thanks to my colleague who told me about this website today on the campus when I was in total doubt as to where to go to have a sophisticated guide for my assignment on a care plan and indeed when I entered this lab today I saw myself at the center of my solution.
This website has become a lifesaver! Use caution when administering hypertonic saline solutions because of their potential for causing intravascular fluid volume overload and pulmonary edema. Teach patients to notify a nurse if they develop breathing difficulties or if they feel their heart is beating very fast. Isotonic is when water and solute are at equal levels inside and outside of the cell.
There is no shift of fluid in or out of the cell. Hypotonic solutions is when there is less value in the solution and more solute in the cell, so water goes inside the cell. Hypertonic solutions are when more solute is in the solution and less solute in the cell, so water goes outside of the cell. Study Guides Flashcards Online Courses.
IV Fluids. Welcome to this video tutorial on IV fluids. IV fluids can be placed in two general categories: colloids and crystalloids. Our focus for this lesson will be crystalloids, which is a watery-type solution of mineral salts and other water-soluble molecules. Isotonic Solutions In an isotonic solution, the osmotic pressure is constant inside and outside of the cells.
When administering hypertonic fluids, it is essential to monitor for signs of hypervolemia such as breathing difficulties and elevated blood pressure. Table D10 Used to treat severe hyponatremia and cerebral edema.
Monitor closely for hypervolemia, hypernatremia, and associated respiratory distress. Do not use it with patients experiencing heart failure, renal failure, or conditions caused by cellular dehydration because it will worsen these conditions. Osmolarity is defined as the proportion of dissolved particles in an amount of fluid and is generally the term used to describe body fluids.
As the dissolved particles become more concentrated, the osmolarity increases. Osmolality refers to the proportion of dissolved particles in a specific weight of fluid.
The terms osmolarity and osmolality are often used interchangeably in clinical practice. Skip to content When patients experience deficient fluid volume, intravenous IV fluids are often prescribed. Isotonic Solutions Isotonic solutions are IV fluids that have a similar concentration of dissolved particles as blood.
Figure Monitor closely for hypervolemia, especially with heart failure or renal failure. Often used during surgery. What is a hypotonic solution? Is d5w a hypotonic solution?
