What Does The SWFI Medical Abbreviation Mean?

In this post, we will be looking at the SWFI medical abbreviation, its meaning, and when it is used.

Medical abbreviations are shorthands used by doctors and other health workers when communicating with one another to make the work of attending to patients easier.

In recent times, modern doctors have been advocating for doctors to cut down on the use of certain medical abbreviations as they cause confusion in inpatient care. Misinterpretation of patients’ prescriptions is among the commonest causes of increased patient mortality in hospitals.

But this does not mean that some medical abbreviations have been phased out completely. You can still find them in patients’ folders during clinics and rotations and you should know what they mean and why they are used.

Sterile water for injection

The SWFI medical abbreviation stands for “Sterile Water For Injection”. The term water for injection is derived from Latin; aqua ad injectabilia or aqua ad injectionem.

The ordinary water for injection is a water of very high quality with minimal contamination. The sterile water for injection is used in preparing solutions that are to be given via injection either in a vein, muscle, or subcutaneously.

The Nature Of The Sterile Water For Injection

Sterile water for injection is an isotonic solution comprising mainly of water prepared through osmotic distillation. When given intravenously, care must be taken to ensure that it is isotonic because it might result in the breakdown of red blood cells (hemolysis).

Uses of Sterile Water For Injection.

Water for injection is used for many procedures in both medicine and surgery. It is commonly used;

  • For irrigation during surgeries and some other procedures in medicine.
  • It is used in reconstitution for the administration of parenteral medications
  • It is used in the dissolution of solute to make an approximately isotonic solution
  • It is as well used while setting an intravenous line to ensure the cannula is in the blood vessel before administering the medication.

Route Of Administration

Sterile water for injection is administered parenterally only. It must not be injected into the veins or else it is made isotonic by the addition of a proportional and adequate amount of solute. If it is injected into the veins without being in the isotonic form, it could result cause adverse reactions in the vein.

Some Side-Effects Of Administering Water For Injection:

It could lead to break down of red blood cells (hemolysis) if not isotonic

This can then lead to kidney problems due to the deposition of blood pigments (hemoglobin) in the renal tubules and glomeruli.

When an excessive volume of water for injection is given, it could lead to fluid overload thereby causing low blood sodium (hyponatremia) and electrolyte imbalance.

It could also result in redness and tenderness of the injection site if not properly administered parenterally.

Could cause fever, bruising, swelling, or pain at the site of the injection.

Storage

Water for injection is stored in the pharmacy or in the ward in a cool dry place where the temperature is always below 25 degrees Celcius.
