NURSING NOTES IV THERAPY

Intravenous Administration




When other routes of medication administration are ineffective, the intravenous (IV) route becomes
the preferred method due to its ability to provide rapid and accurate drug delivery. This approach is
ideal for medications that cannot be absorbed orally because of large molecular size or susceptibility
to destruction by the digestive system.


Intravenous (IV) medication administration involves delivering
medications directly into a patient’s bloodstream through a vein. This method allows for rapid onset
of action, and precise control over drug levels, and is essential in various medical settings, including
emergency care, surgeries, and chronic disease management.


Advantages

IV medications deliver numerous benefits, demonstrating effectiveness in various clinical
scenarios and meeting diverse therapeutic needs. This method of administration is particularly
valuable in providing timely and controlled treatment.


 Rapid absorption.
IV administration allows medications to quickly enter the bloodstream, providing immediate
effects where it is needed in emergencies where prompt treatment is necessary, such as in
cardiac arrest, severe allergic reactions, or acute pain management.
 Full bioavailability.
Medications given intravenously bypass the digestive system and liver metabolism, ensuring
that the entire dose reaches the bloodstream. This guarantees full bioavailability, making the
drug more effective.
 Precise control over dosage.
IV administration allows for accurate and controlled dosing. This is particularly important for
medications with a narrow therapeutic window, where exact dosages are vital to avoid
toxicity and ensure efficacy.

,  Continuous drug delivery.
IV infusion can provide a continuous and steady supply of medication over time. This is
beneficial for maintaining consistent therapeutic levels in the blood, as seen with medications
for chronic conditions or during surgery.
 Immediate effect for pain relief.
IV administration is highly effective for acute pain management, delivering pain relief almost
instantly compared to oral or other routes. This is particularly useful in postoperative settings
or for severe, sudden pain.
 Appropriate for patients unable to take oral medications.
Patients who are unconscious, intubated, or have gastrointestinal issues that prevent them
from taking oral medications can still receive necessary treatments through IV administration.
 Effective for large volume administration.
IV routes can handle more fluids and medications than other routes, making it ideal for
administering fluids for hydration, blood transfusions, and total parenteral nutrition (TPN).
 Enhanced monitoring and immediate adjustments.
IV administration facilitates close monitoring of drug effects and allows for rapid adjustments
in dosing or medication changes.
 Use in diagnostic procedures.
IV administration of contrast agents is essential for certain diagnostic imaging procedures,
improving the accuracy and effectiveness of diagnostic tests such as CT scans and MRIs.



Disadvantages

Although the intravenous route offers many advantages, it also has some downsides. Here are a few
disadvantages


 Higher cost.
This method often involves more expensive equipment (syringes, needles, IV sets, infusion
pumps) and requires trained personnel, making it more costly compared to other routes
like oral administration.
 Pain and compliance issues.
Injections cause pain, leading to poor patient compliance, making them a less ideal delivery
method.
 Technical skill required.
Improper administration, including wrong needle placement or lack of sterilization, can cause
complications, discomfort, and lower the drug’s effectiveness.
 Limitations for protein products.
Injections are not suitable for delivering protein products requiring sustained levels, limiting
their effectiveness for such treatments.
