Cleaning, Sterilization, and Disinfection

11.5K
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...

Methods of Sterilization II: Chemical Methods

9.4K
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,...

Suctioning the Nasopharyngeal Airway

6.4K
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

PPE Use in Healthcare Settings II: Doffing

1.6K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Suctioning the Oropharyngeal Airway

1.6K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Endoscopic Procedures I: Esophagogastroduodenoscopy

2.3K
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Summary

Most UK hospitals decontaminate flexible nasal endoscopes using chlorine dioxide wipes, though automated machines are also common. However, many departments lack specific protocols for high-risk patients, indicating a potential gap in infection control practices.

Area of Science:

  • Medical Microbiology
  • Infection Prevention and Control
  • Otolaryngology

Background:

  • Flexible nasal endoscopes are critical for diagnosing ear, nose, and throat (ENT) conditions.
  • Proper decontamination of these instruments is essential to prevent cross-infection.
  • Current practices in the UK require investigation to ensure patient safety.

Purpose of the Study:

  • To assess the current decontamination methods for flexible nasal endoscopes in UK ENT departments.
  • To identify the most frequently used decontamination agents and equipment.
  • To determine adherence to protocols, particularly for high-risk patient groups.

Main Methods:

  • A national survey was conducted via postal questionnaire.
  • The survey targeted Sisters in Charge of 200 ENT outpatient departments across the UK.
  • An overall response rate of 60.5% was achieved.

Main Results:

  • Chlorine dioxide wipes were the predominant decontamination method, utilized by 58% of respondents.
  • Automated decontamination machines were employed in 34% of surveyed departments.
  • Only 7% of hospitals reported using flexible sheaths, and many lacked specific high-risk patient protocols.

Conclusions:

  • Chlorine dioxide wipes are the leading method for flexible nasal endoscope decontamination in the UK.
  • A significant proportion of departments rely on automated machines, suggesting a trend towards mechanization.
  • The absence of dedicated high-risk patient protocols highlights a critical area for improvement in infection control standards.
