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:
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.
