The Evidence for Evolution02:55

The Evidence for Evolution

48.5K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

What is an Experiment?01:12

What is an Experiment?

19.2K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Gene Therapy00:59

Gene Therapy

27.7K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Thomson's e/m Experiment

7.0K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

One-Compartment Model: IV Infusion01:09

One-Compartment Model: IV Infusion

543
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...

Controls in Experiments01:13

Controls in Experiments

18.5K
When conducting an experiment, it is crucial to have control to reduce bias and accurately measure the dependent variables. It also marks the results more reliable. Controls are elements in an experiment that have the same characteristics as the treatment groups but are not affected by the independent variable. By sorting these data into control and experimental conditions, the relationship between the dependent and independent variables can be drawn. A randomized experiment always includes a...

Summary

Stopcocks used in infusion therapy pose contamination risks due to their open lumens, as shown by research. This review examines evidence and practices to suggest changes for reducing these risks in patient care.

Area of Science:

  • Medical Devices
  • Infection Control
  • Fluid Dynamics

Background:

  • Stopcocks are widely used for infusion therapy across all patient demographics and healthcare settings.
  • Concerns regarding intraluminal contamination risks associated with open stopcock lumens have been increasingly validated by research over the last two decades.
  • Fluid flow dynamics within stopcocks have also been a subject of recent scientific investigation.

Purpose of the Study:

  • To conduct an integrative literature review on stopcock-related contamination and fluid dynamics.
  • To survey clinician practices concerning stopcock use.
  • To identify potential practice modifications to mitigate risks associated with stopcock use in infusion therapy.

Main Methods:

  • Integrative literature review of published evidence on stopcock contamination and fluid dynamics.
  • Clinician practice survey to assess current usage and awareness of risks.
  • Analysis of existing evidence and reported practices.

Main Results:

  • Published studies confirm the risk of intraluminal contamination through open stopcock lumens.
  • Research highlights the influence of fluid flow dynamics on stopcock performance and potential contamination.
  • Survey data provides insights into current clinical practices and awareness levels regarding stopcock risks.

Conclusions:

  • Stopcock design and usage present inherent risks of microbial contamination during infusion therapy.
  • Evidence supports the need for critical evaluation of current stopcock practices.
  • Recommendations for practice changes are proposed to enhance patient safety and reduce infection risks.
