Summary
This study compares closed safe intravenous systems to open systems, evaluating clinical performance and complication rates. The research, led by nurses, aims to validate the effectiveness of closed systems in preventing infections and improving patient safety.
Area of Science:
- Nursing research
- Medical device evaluation
- Infection control
Background:
- Safety peripheral intravenous systems are widely used globally.
- The Madrid region pioneered their adoption in Spain.
- Systems evolved from sharps injury protection to include patient protection (pathogen entry prevention).
Purpose of the Study:
- To prospectively and randomly investigate the clinical performance of a closed safe intravenous system versus an open system (COSMOS).
- To provide nursing-validated answers on peripheral venous catheterization implications in intravenous therapy.
- To conduct pioneering research as the first clinical trial on medical devices in a legislated environment, led entirely by nurses.
Main Methods:
- Prospective and randomized study design.
- Comparison of Compact Closed System versus Mounted Open System (COSMOS).
- Evaluation of parameters including ease of handling and overall costs.
Main Results:
- The study aims to compare effectiveness based on complication-free survival time.
- Rates of catheter-related complications (phlebitis, pain, extravasation, blockage, infection) will be assessed.
- Catheter colonization rates and ease of handling will be analyzed.
Conclusions:
- Further articles will detail the study's results and findings.
- The research seeks to scientifically validate the benefits of closed intravenous systems.
- This study contributes novel insights into intravenous therapy practices from a nursing perspective.

01:27Parentral Nutrition: Centeral and Peripheral Parental Nutrition
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

01:09One-Compartment Model: IV Infusion
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...

01:15Two-Compartment Open Model: IV Infusion
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...

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
01:12Two-Compartment Open Model: Extravascular Administration
The two-compartment model for extravascular administration represents a drug's absorption and distribution process. It features a central compartment, where the drug is first absorbed, and a peripheral compartment, which illustrates the drug's distribution throughout the body. The rate of change in drug concentration in the central compartment is calculated by three exponents: absorption, distribution, and elimination.
The absorption exponent (ka) indicates the speed at which the drug is...

01:28Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices
Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...
