IV Infusion

IV Infusion

IV Infusion is the administration of nutrients, electrolytes, minerals, and fluids into a patient’s veins. IV infusion allows the intake of nutrients when gastrointestinal absorption of food is inaccessible or insufficient.

History of IV Infusion

Current IV therapy is less than 100 years old. Yet, the knowledge of IV infusion is ancient. But because of a lack of understanding about sterility, infection control, and other scientific methods, original attempts to deliver IV fluids and drugs met with little success. The greatest advance in drugs, equipment, and procedures has occurred in the past 25 years. The methods and parameters of IV therapy are developing.

Importance of IV infusion

Good nutrition is important for the maintenance of health and to avoid disease. Malnutrition problems occur during a hospital stay. Patients are either unable to feed themselves by mouth or they dislike hospital food. IV Infusion solves the problem of malnutrition by bypassing the oral route of food intake. IV infusion delivers minerals and nutrients straight into the bloodstream where they are readily absorbed. In critical-care situations rapid effect of fluids delivered into the bloodstream is essential.

Advantages of IV Infusion

  • IV Infusion is life-saving for patients who cannot maintain nutrients intake for long periods.
  • Body fluids lost by, diarrhea, vomiting, or excessive perspiration produce illness and can cause death. IV Infusion is a quick way to compensate for the loss of bodily fluids.
  • The relationship between the concentrations of sodium and potassium electrolytes in the cells and the extracellular fluid causes the water to flow into and out of the cells. In case of shock electrolytes balance can be disturbed. IV Infusion can restore the electrolyte balance within the body.

Who needs IV Infusion?

Patients with the problem of

  • Loss of appetite.
  • Loss of consciousness.
  • Inability to swallow.
  • Dehydration
  • Excessive nutrient loss.
  • Intestinal failure.
  • Excessive metabolic demands.
  • Unavailability of eternal tube feeding.
  • Pancreatic disease
  • Small intestinal disease.

IV infusion is needed after surgery. IV Infusion is the only solution for patients who suffer from respiratory problems, in whom ETF cannot be used.

Weaknesses of oral administration

  • Advancement of age causes impairment of swallowing which hampers oral administration of medicine.
  • In graphic studies of transit rates of hard gelatin capsules and tablets, elderly subjects were frequently unable to clear the capsules. This appears to be due to the separation of the bolus of water and capsule in the oropharynx, resulting in a ‘‘dry’’ swallow. As a result, capsule adherence occurred in the lower third of the esophagus.
  • The oral administration of many drugs and drug candidates is prevented by their poor penetration through the intestinal barrier.
  • The rate of absorption of medicine by Oral administration is 10 percent compared to this IV Infusion has more success.
  • Most of the data about orally administered drugs are obtained from healthy individuals. However, many drugs are administered to patients who are sick. A disease might affect either their absorption or overall bioavailability.
