#3351 TRIAL OF ISOLATED HAEMODIALYSIS WITH PATIENT-ENTRY TENT AND HYPOCHLORITE MIST

Abstract Background and Aims The global spread of COVID-19 has posed a serious threat to patients receiving renal replacement therapy the staff who treat them. Every time they patient or operate machine, have wear personal protective equipment (PPE). In order reduce burden on our staff, we introduced two pieces equipment. One is hypochlorous acid mist for room surface disinfection using CLFine®. other an AIR ZIPPER® isolation tent in existing room. Both products were manufactured by Nipro Corporation Osaka, Japan. However, there was no evidence support use ultrasonic humidifier. Therefore, conducted “28-day repeated inhalation toxicity study” rats with third party organisation confirmed results as toxicologically safe. According Occupational Safety Health Act, also school environmental health, concentration chlorine air 0.5 ppm less (8 hours/day, 5 days/week less). CL Fine® shown antiviral effect within these regulations. size about fifth standard 10m3 size, down 2m3. Powerful, high-efficiency particulate filter pumps been fitted replace than minutes at low flow rates (0.4 m3/min airflow), enabling it below negative pressure 2.5 Pascal. addition, equipped intake valves that open close single direction towards inside tent. Prior introduction ZIPPER®, had PPE N95 mask when operating puncturing returning blood patient. Method Patients fever contact infected asked enter AIRZIPPER®. haemodialysis machine placed outside. zipper AIRZIPPER® could not be closed until puncture procedure completed. To viruses outside tent, high volume (air rate 0.9 m3/min) allows one-way from inside. Following puncture, sealed adjusted reach recommended Pa above 1 minute. Furthermore, CLFine® ability disinfect ZIPPER®. after 30 zip room, operated safe zone. Results On 13 January 2022, arrived Toshin Clinic all carrying subsequently developed disease isolated haemodialysed. Quarantine dialysis performed 156 patients, including those fever. A total 96 sessions 22 (male/female: 19/3, age: 69.8 ± 14.2 years, HD duration: 5.38 3.8 years) SARS-CoV-2 infection clinic. Fortunately, transmission died. Conclusion These control measures helped workload prevent infections. conclusion, present method should providers deal Covid 19 infections well new future.
