Intravenous therapy or IV therapy is the giving of liquid substances directly into a vein. It can be intermittent or continuous.
IV therapy will often be used to correct electrolyte and fluid imbalances in the body
Fluid and electrolyte imbalances often occur as a result of the adrenocortical stress response associated with severe physical trauma or stress (such as surgery).
- The physiological adrenocortical stress response of the body causes the retension of sodium (Na2+) and Water (H2O) by the body
- as Sodium and Water is lost, potassium (K+) is lost
- electrolyte imbalances are often seen in first 2-5 d post-surgery
- the severity of the stress influences degree of electrolyte imbalance
- the more extensive the surgery (Sx) the greater the physiological stress response
- excess or depletion of K+ increases the prevalence of dysrhythmias both pre and post operatively
- A higher prevalence of fluid and electrolyte imbalances in often seen in patients with preexisting, renal, GI or Cardiovascular disorders.
