中文摘要

目的：氯化合物NaDCC消毒錠稀釋溶液，其保存時限及殺菌力皆優於漂白水，故比較兩種消毒溶液使用於醫療環境消毒時ATP變化之差異，並應用於新型冠狀病毒之環境消毒。方法：使用不同消毒溶液（NaDCC組與NaCIO組）之拋棄式抹布在進行常規環境清潔時比較ATP變化之差異，分別於清潔前及清潔後0.5小時、2小時、4小時、24小時分別比較之。使用NaDCC溶液於新型冠狀病毒病人之病室環境消毒，進行SARS-CoV-2 PCR採檢。結果：NaDCC溶液從清潔後2小時到4小時在ATP的下降幅度顯著優於漂白水組，顯示NaDCC溶液消毒後維持效果優於漂白水（P.003），且NaDCC溶液應用於新型冠狀病毒病人之環境消毒後，檢驗SARS-CoV-2 PCR均為陰性。結論：使用NaDCC於醫療環境消毒，其消毒效力之持續時間優於漂白水之外，其人力及時間亦均較節省。且將其應用於新型冠狀病毒環境消毒除便利性高，亦可有效避免病毒傳播，本研究結果可提供各醫療機構於環境消毒上之參考。
英文摘要

Objectives: When using bleach, its dilution ratio has to be calculated and it can only be used for 24 hours after dilution. Moreover, it is instable, has strong alkaline corrosion, and leaves a residue after use. Therefore, it is difficult to appropriately and adequately implement its use by the cleaning staff and difficult to master its disinfection effect. Diluted solution of sodium dichloroisocyanurate (NaDCC) tablets has a longer storage life and stronger bactericidal effect than bleach. Our institution has been using NaDCC to disinfect environments with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and have shared our experience. Methods: The differences in ATP changes when using a disposable cleaning cloth with different disinfection solutions (the NaCIO group and NaDCC group) to perform routine environment cleaning were investigated by comparing the ATP values before cleaning and at 0.5, 2, 4, and 24 hours after cleaning. The two solutions were also applied during environmental disinfection in institutions admitting and treating patients with SARS-CoV-2 infection and environment disinfection of nursing stations. Results: Although the t-test did not reveal any significant difference in ATP at the different time points, the rising trend of the NaDCC group was continuously lower than that of the NaCIO group, which still was within the reference range. The decline in ATP from 2 hours to 4 hours after cleaning with NaDCC disinfection solution was better than that in the bleach group, indicating that the disinfection effect of the NaDCC disinfection solution was better than that of bleach (P = 0.003). In addition, the allocated working hours of the NaDCC group were significantly lower than those of the NaCIO group. After application in disinfecting environments contacted by patients with SARS-CoV-2 infection, it was confirmed that there was no viral residue in the environments. Conclusions and Suggestions: When applied in environment disinfection, NaDCC not only had a longer duration of disinfection effect than bleach but also had lower storage of disinfection solution, labor, and time costs. In addition, its practicality and degree of satisfaction were significantly higher among staff. The results of this study can provide references for medical institutions in environment disinfection and infection control.
