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...

Area of Science:

Surgical Instrumentation
Medical Device Sterilization
Laparoscopic Surgery

Context:

Ultrasonic scissors are critical tools in minimally invasive surgery.
The cost-effectiveness of surgical instruments is a growing concern.
Evaluating the reliability of resterilized medical devices is essential for safe clinical practice.

Purpose:

To compare the functional reliability and handling of resterilized ultrasonic scissors against new, single-use disposable ones.
To assess key performance parameters including activation force, cutting and coagulation effects, and operational disturbances.
To determine the cost-efficiency and potential impact on surgical efficiency.

Summary:

A prospective randomized study evaluated 51 new and 49 resterilized ultrasonic scissors across 94 operations.

No significant differences were found in activation force, cutting effect, or coagulation between new and resterilized instruments.

Both groups exhibited rare error messages and noise, with a low exchange rate for both new (6) and resterilized (2) instruments.

Impact:

Resterilized ultrasonic scissors offer comparable reliability to new instruments.
Utilizing resterilized instruments significantly reduces surgical costs.
This practice can enhance overall efficiency in laparoscopic surgical procedures.
