Standard Precaution01:26

Standard Precaution

3.2K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.4K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Atomic Emission Spectroscopy: Interference01:30

Atomic Emission Spectroscopy: Interference

785
In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

2.0K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Area of Science:

  • Healthcare-associated infections
  • Occupational health and safety
  • Medical device safety

Background:

  • Occupational exposure to blood and body fluids is a significant risk for healthcare professionals.
  • While needlestick injuries are well-researched, the risk of transmission via spatter from safety-engineered syringes is less understood.

Purpose of the Study:

  • To examine the risk of blood-borne virus transmission through spatter contamination from commonly used safety-needle syringes.
  • To identify safety needle designs that minimize spatter contamination.

Main Methods:

  • Evaluation of spatter contamination risk from three types of safety-needle syringes.
  • Analysis of potential for transmission following syringe discharge and safety activation.

Main Results:

  • The study suggests that spatter contamination from safety-needle syringes presents a new and significant occupational hazard.
  • The risk varies among different types of safety needles examined.

Conclusions:

  • Spatter contamination from safety needles is an emerging occupational hazard in healthcare settings.
  • Further investigation is required to quantify this risk and guide the development of safer needle technologies to minimize exposure.
