Abstract
Objectives: This study aimed to evaluate the efficacy of the ‘Si-Washer’ in cleansing gynaecological laparoscopic instruments. Materials and Methods: The instruments were randomized into either a control group or an experimental group using a block randomization method, with sequences securely concealed in sealed envelopes. The control group underwent traditional manual cleansing, whereas the experimental group utilized the Si-Washer. Results: A total of 302 instruments were randomized, with 151 allocated to each group. The median operative duration was 135.0 minutes (interquartile range [IQR] 115.0–175.0), and the median blood loss was 50.0 mL (IQR 20.0–100.0). No significant differences were observed between the groups regarding diagnostic parameters, operator expertise, operation types, operative time, instrument types, surgical complications, irrigation volume or blood loss. The Si-Washer achieved 100% cleanliness at an adenosine triphosphate cut-off of <150 relative light units, markedly surpassing the manual method, which achieved 58.9% cleanliness at the same threshold. Conclusion: The Si-Washer effectively decontaminated gynaecological laparoscopic instruments and alleviating the workload of operating theatre nursing staff.
