Cleaning, Sterilization, and Disinfection

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Enhanced Elimination of Poison

Enhanced Elimination of Poison

Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.
Renal excretion is the...

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
Hand washing...

Methods of Sterilization II: Chemical Methods

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based Precautions II: Airborne and Protective Environment

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...

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

Summary

Selective decontamination of the digestive tract (SDD) prevents infections and reduces mortality in critically ill patients. Evidence shows SDD decreases resistant bacteria without increasing workload or costs.

Area of Science:

Critical Care Medicine
Infectious Disease Prevention
Microbiology

Context:

Critically ill patients on prolonged mechanical ventilation are at high risk for endogenous infections.
Historical concerns regarding bacterial resistance and mortality impact of SDD have been challenged by recent evidence.
Implementation requires multidisciplinary cooperation, training, and continuous monitoring.

Purpose:

To evaluate the effectiveness of Selective Decontamination of the Digestive Tract (SDD) in preventing infections and reducing mortality.
To address historical concerns about the development of bacterial resistance and impact on mortality.
To assess the impact of SDD on healthcare professionals' workload and hospital costs.

Summary:

Recent clinical trials demonstrate that SDD significantly reduces the incidence of resistant bacteria and improves mortality rates in critically ill patients.
Studies indicate no increase in bacterial resistance or healthcare costs associated with SDD implementation.
Successful SDD integration necessitates strong leadership, interdisciplinary collaboration, professional training, and ongoing outcome surveillance.

Impact:

SDD offers a proven strategy to decrease infection rates and mortality in intensive care units (ICUs).
The findings support the broader adoption of SDD as a standard preventive measure for critically ill patients.
Incorporation into national and international guidelines, supported by surveillance programs like ENVIN-HELICS, is recommended for effective implementation and monitoring.
