The Process and Purpose of Intravenous Therapy

The Process and Purpose of Intravenous Therapy

Dec 01, 2020

The term intravenous means “within a vein” but is mostly used for IV therapy. Intravenous (IV) therapy is, therefore, the process of administering fluids straight into the vein. IV therapy is either intermittent or continuous. Continuous IV is also called an intravenous drip.

People can be recommended for IV due to many reasons. Mostly, IV therapy in Atlanta is used to replenish the body fluids you lost through dehydration.

When you lose a substantial amount of water, for any reason whatsoever, there is an imbalance in body electrolytes. It affects the brain’s cognitive function and stresses of other body systems.

Your blood concentration rises, which signals the kidneys to retain more water. Your urine output therefore decreases. With concentrated thicker blood, the heart strains to work harder to balance the pressure throughout the body.

It’s through these compensatory actions that the patient becomes at risk.

Through the fluid restoration, this imbalance is corrected, which recuperates your normal body functioning.

For what reasons is Intravenous Therapy Administered

Your Creative Medspa healthcare specialist will recommend an IV therapy for any of these reasons:

  • To provide bodily fluids when you cannot consume adequate fluid amounts through the mouth.
  • To add salts and various electrolytes when there is an electrolyte imbalance
  • Providing glucose (dextrose) in the body. Glucose is the major fuel for body metabolism.
  • To boost the body with water-solvable vitamins and medications
  • If you need a lifeline for essentially vital medications

Basics of Intravenous Fluids

The essential players of IV administration mechanisms are osmosis and osmotic pressure. Various types of fluids are designed to create specific reactions in terms of osmotic blood pressure. This is, of course, depending on what the patient aims to achieve.

Essentially, when something flows in or out of your cells, it creates a certain reaction. So, when we talk about types of IV fluids and solutions, we refer to how they affect the cellular osmotic pressure.

There are two types of IV fluids, Crystalloids and Colloids.

  • Crystalloids

These fluids contain tiny molecular particles that can pass through semi-permeable membranes. Take the cell membrane as a kind of a strainer so that crystalloid particles are small enough to get through.

Once inside the cell, the solutions make available the contents they carried to the cells to use them.

For this reason, crystalloids are used to increase the body’s fluid volume. They also increase the intravascular space in lost blood plasma due to burns and trauma or post-surgery recovery.

Crystalloids are of three types:

Hypotonic: They are used when the fluid outside has a lesser concentration than the cells’ fluid. Water, therefore, moves into the cells from the extracellular space.

Hypertonic: Administered more solutes are in the extracellular fluid, so water flows from inside the cells.

Isotonic: Intracellular and extracellular fluids have an equal osmolarity, so there is no water flow between them.

  • Colloids

Colloids are made to have larger molecules. Unlike crystalloids, their molecules do not penetrate the semi-permeable cell membranes readily.

In medical terms, it means that colloid solutions remain intravascular, unlike crystalloid solutions. It means that they remain in the bloodstream rather than entering the blood cells. Colloids also stay in the bloodstream for a longer period than crystalloids.

Therefore, they are used as a plasma booster to resuscitate the fluid when, for instance, the patient has suffered a severe hypovolemic shock.

Steps before an IV Therapy

Before administering an IV therapy in Atlanta, GA, your physician must take some time to prepare.

First, they have to record a directive, which includes determining the type of solution to give, route of administration, the exact dosage you need, duration of completion for the medication, and fill their signatures.

They then clean your hand using handwashing agents or antimicrobial soap. The physician also has to sanitize their hands to wash off any contamination by blood or other body fluids and germs gotten from other patients.

The doctor gathers tools to use for the procedure, including glass and plastic containers to use with the IV pumps. The prepping solution and a one-inch tape are then set for use.

Next is patient assessment and physical examination. It includes identifying the patient and evaluating their preparedness for the procedure. A medical diagnosis is conducted to check for any vascular conditions, assessment for allergies, and bleeding tendencies.

If found ready, your doctor proceeds to determine the right solution for you and selects an injection site.

If your veins are not dilated, your doctor can use any of these techniques to dilate them:

  • Fist clenching
  • Warm compresses
  • Blood pressure cuff
  • Tapping the vein
  • Latex tourniquet.
