Which method is acceptable for manual cleaning of flexible endoscopes?

The acceptable method for manual cleaning of flexible endoscopes involves cleaning below the water level during the process. This technique minimizes the risk of contamination and reduces the likelihood of splashing potentially infectious materials. When cleaning below the water level, any debris or bioburden is more effectively contained within the water, making the process safer for the practitioner and assisting in thorough cleaning due to the submerged environment.

Using water effectively helps to flush out debris, while the action of cleaning, whether it’s scrubbing or rinsing, is reinforced by the presence of the water. Manual cleaning at or above the water level could increase the risk of sanitation failure due to potential splashes and increased exposure to the air, which can be laden with microorganisms.

This method is emphasized in Standard Operating Procedures (SOPs) in endoscopy to ensure that flexible endoscopes are properly processed before they undergo further disinfection or sterilization. Therefore, cleaning below the water level aligns with best practices for maintaining the functionality and safety of endoscopic instruments.
