摘要

Abstract

Objective

To explore the suitable cleaning method for ophthalmic instruments containing silicone oil by comparing the effect of two cleaning methods on the cleaning effect of 23G flute needles for vitrectomy

and to establish a standard procedure for cleaning ophthalmic flute needles to improve the cleaning quality and reduce the risk of postoperative infection in ophthalmic surgery.

Methods

Sixty ophthalmic vitrectomy 23G needles containing silicone oil were rando mly divided into experimental and control groups. The control group was cleaned directly by hand at a conventional temperature with a weak alkaline cleaning agent at 30 °C. The experimental group was cleaned by hand with a modified weak alkaline cleaning agent at 50 °C soaked in an ophthalmic ultrasonic cleaner for 10 minutes and then sonicated for 5 minutes. The silicone oil residue content of the ophthalmic needle was determined by gas chromatography before and after cleaning

and the silicone oil removal rate was calculated

and the cleaning pass rate of the ophthalmic needle was quantified by ATP for both groups.

Results

The removal rate of silicone oil from the ophthalmic needle was 98.65% in the experimental group and 85.32% in the control group (

0.05)

and the cleaning ATP quantification rate was 100% in the experimental group and 80% in the control group (

0.05).

Conclusion

The use of a modified 50 °C weak alkaline detergent soaked for 10 minutes followed by ultrasonication for 5 minutes and then manual cleaning was more effective in removing silicone oil residues from 23G flute needles used for vitrectomy

and improved the quality of instrument cleaning.
