Study: Manual, automated cleaning equally effective for laparoscopes

Editor’s Note

In this experimental laboratory study, all cleaning and rinsing methods tested were effective in reducing the levels of organic residues on laparoscopic instruments.

Four methods were examined:

  • manual-only cleaning and rinsing with potable tap water
  • manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning without rinsing
  • manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning and rinsing with potable tap water
  • manual cleaning and rinsing with potable tap water, followed by ultrasonic cleaning and rinsing, first with potable tap water and then with sterile distilled water.

None of the cleaning methods resulted in statistically significant differences in the levels of the organic residues tested (ie, protein, hemoglobin, and carbohydrates).

No advantage is gained by supplementing manual-only cleaning with automated ultrasonic cleaning of laparoscopic instruments or by rinsing with potable versus sterile distilled water, the researchers concluded.
