The aim of our study was to evaluate the difference of effectiveness between daily and after-each-case room disinfection in the endoscopy unit during the COVID-19 pandemic.
This study divided into 2 groups: daily room disinfection and after-each-case room
disinfection. Each group was also subdivided into general anesthesia or non-general
anesthesia gastroscopy, and with or without ventilation consultation room.
Samples collection include: operation unit air (six-stage sieve percussion air sampler for
sampling, airflow rate 28.3L/min, sampling time 4 min); workstation's mouse (wiping sterile
cotton for sampling); endoscopist's gown, control panel buttons, and patient's bed headboard
(contact plate for sampling).
Other: after-each-case room disinfection
After-each-case room disinfection was defined as after completing each case.
Other: daily room disinfection
Daily room disinfection was defined as disinfection after completing 8 non-general anesthesia gastroscopy or 4 general anesthesia gastroscopy.
Inclusion Criteria:
- All the cases received gastroscopy.
Exclusion Criteria:
- High-risk personal through contact history, symptoms, body temperature, COVID-19 virus
nucleic acid testing and chest computed tomography (CT) scan.
