Summary
The manual flow regulator is the most cost-effective and easiest to use for intravenous (IV) therapy in low-resource settings. This method improves patient safety without straining resources, unlike more complex IV infusion devices.
Area of Science:
- Medical Devices
- Healthcare Technology
- Global Health
Background:
- Intravenous (IV) therapy is critical for critically ill patients.
- Low-resource settings face barriers to IV infusion pumps: cost, electricity, and support.
- Inaccurate traditional IV drop-counting poses patient risks.
Purpose of the Study:
- To compare the efficacy of different IV infusion methods in low-resource settings.
- To identify an IV method balancing accuracy, cost, and electricity reliance.
- To evaluate usability and cost-effectiveness of IV devices.
Main Methods:
- Prospective mixed methods study involving nurses, residents, and students.
- Comparison of drop counting, manual flow regulator, infusion pump, and DripAssist variations.
- Data collected on setup time, fluid volume, and user-rated understandability, time, and operability.
Main Results:
- Manual flow regulator had the fastest setup, was most cost-effective, and easiest to use.
- DripAssist with manual flow regulator was most time-consuming and difficult to operate.
- Manual flow regulator rated highest for ease of use and understandability.
Conclusions:
- Manual flow regulator is the most cost-effective and user-friendly IV method for low-resource settings.
- While DripAssist/Manual flow regulator combination improves accuracy, it's less operable.
- Healthcare providers can adapt these devices to enhance IV medication safety with minimal resource strain.

Intravenous (IV) infusion is often utilized when continuous and controlled drug delivery is necessary, such as during surgery or in the treatment of chronic diseases. This method offers numerous advantages, including immediate drug action, precise control over dosage, and bypassing the first-pass metabolism.
The one-compartment model for IV infusion uses mathematical equations to describe the rate of change in drug quantity in the body. At steady-state or infusion equilibrium, the drug input...

01:25Routes of Drug Administration: Parenteral
1.9K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.

A two-compartment model is a vital tool in pharmacokinetics, providing an essential understanding of drug behavior, especially for those administered via zero-order intravenous infusion. This model outlines two compartments: the central compartment, where elimination occurs, and the peripheral compartment.
The model illustrates the decrease in plasma drug concentration from the central compartment with a specific equation. It shows that under steady-state conditions, the drug's input rate...

The two-compartment model for intravenous (IV) bolus administration illustrates drug distribution in the body, subdividing it into central and peripheral compartments. This model operates on the concept of two-compartment kinetics. The drug's plasma concentration shows a bi-exponential decline following IV bolus administration, signaling the presence of two disposition processes: distribution and elimination.

Clearance is a key pharmacokinetic parameter that quantifies the volume of body fluid from which a drug is entirely removed within a specific time frame. It is crucial in assessing how a drug is eliminated from the body and has critical clinical applications.
In the one-compartment open model for intravenous (IV) bolus administration, clearance is estimated by dividing the elimination rate by the plasma drug concentration. This equation leverages the elimination rate constant and the apparent...

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
