Background:
Contaminated medical products may be vectors for infections. A safe disinfection method for the optical instruments used by ENT specialists is undoubtedly needed. So far, a standard method that sufficiently covers the risk of infection for patients and medical staff alike, while serving the need of practicability in daily routine, has not been established.
Patients And Methods:
In the ENT departments of the Mannheim and Kaiserslautern hospitals, a study on the practicability of disinfection rigid optical instruments lacking working channels was conducted using cleaning and disinfection automats. A total of 735 patients were examined (Hopkins 30 degrees and 70 degrees) and the endoscopes subsequently sterilized using a cleaning and disinfection automat.
Results:
Each cleaning cycle took about 40 min. Examining 70-100 patients a day, a minimum of eight 70 degrees Hopkins endoscopes would be needed.
Conclusion:
The sterilization of medical products such as endoscopes is the best practice, but certain hindrances, such as loss of time and costs involved, complicate its general application.
Insights
Disinfection automats offer a practical solution for cleaning ENT optical instruments, but require significant time and multiple devices for daily use. Sterilization remains ideal but faces implementation challenges.
Area of Science:
- Otolaryngology
- Medical Device Sterilization
- Infection Control
Background:
- Contaminated medical instruments pose infection risks.
- Effective and practical disinfection methods for ENT optical instruments are lacking.
- Current methods do not fully address patient safety, staff protection, and routine practicability.
Purpose of the Study:
- To assess the practicability of using automated cleaning and disinfection systems for rigid ENT optical instruments.
- To evaluate the efficiency and requirements of disinfection automats in a clinical setting.
Main Methods:
- A study was conducted in ENT departments using automated cleaning and disinfection systems.
- Rigid optical instruments (Hopkins 30 and 70 degrees) were disinfected after examining 735 patients.
- Disinfection cycles were timed and instrument requirements for daily patient volume were calculated.
Main Results:
- Each cleaning cycle with the automat took approximately 40 minutes.
- To manage 70-100 patients daily, a minimum of eight 70-degree Hopkins endoscopes would be necessary.
- The study highlights the time and equipment demands of automated disinfection.
Conclusions:
- Automated disinfection is a viable method for medical products like endoscopes.
- Significant time investment and high equipment numbers are required for widespread clinical adoption.
- Challenges in time and cost complicate the universal application of sterilization for ENT instruments.

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...
