Insights

Laryngoscopes can spread infections between patients. Repeated cleaning may reduce their reliability, with 86% of staff finding them intermittently dependable, highlighting a need for better infection control.

Area of Science:

  • Medical Microbiology
  • Infection Control
  • Anesthesiology

Background:

  • Laryngoscopes are critical tools in airway management.
  • Potential for cross-infection via laryngoscope contamination is a significant concern.
  • Existing decontamination protocols may impact instrument reliability.

Purpose of the Study:

  • To investigate the role of laryngoscopes as vectors for cross-infection.
  • To assess bacterial and blood contamination of laryngoscope components.
  • To evaluate the reliability of laryngoscopes after repeated decontamination.

Main Methods:

  • Review of case reports on laryngoscope contamination.
  • Analysis of bacterial and occult blood contamination data.
  • Outline of infection control policies for laryngoscope processing.
  • Departmental survey on laryngoscope reliability.

Main Results:

  • Laryngoscope blades and handles can harbor bacterial and blood contamination.
  • Repeated decontamination procedures may lead to a perceived decrease in laryngoscope reliability.
  • A departmental survey indicated 86% of respondents consider laryngoscopes intermittently reliable.

Conclusions:

  • Laryngoscopes pose a risk for cross-infection in clinical settings.
  • Current decontamination methods may compromise laryngoscope functionality.
  • There is a clear need to improve laryngoscope processing and reliability for enhanced patient safety.

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...

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
Tracheostomy Decannulation01:21

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

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...
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
