ARTICLE HIGHLIGHTS
Research background

The use of household disinfectants increased significantly during the coronavirus disease 2019 (COVID-19) pandemic. But there are a few clinical case reports on acute chlorine inhalation poisoning caused by improper mixing of household disinfectants and toilet cleaning solutions.

Research motivation

We summarized the clinical data of patients admitted to our center during the COVID-19 pandemic with acute chlorine inhalation poisoning caused by improper mixing of disinfectants and toilet cleaning solutions to help improve a clinician's ability to treat future cases.

Research objectives

To help improve a clinician's ability. Seven patients with acute chlorine inhalation poisoning caused by improper mixing of disinfectants and toilet cleaning solutions admitted to the National Army Poisoning Treatment Center from March 2020 to September 2021.

Research methods

Retrospective descriptive analysis was performed on the clinical data of all patients.

Research results

Post poisoning, patients may present with symptoms of breathlessness, dyspnea, headache, nausea, cough, pharyngeal discomfort, fatigue, nausea, and depression. Out of seven patients, one had type 1 respiratory failure, and five had bilateral lung effusions or inflammatory changes on chest computed tomography. Six patients received humidified oxygen therapy, and one was treated with non-invasive mechanical ventilation. All patients were treated with glucocorticoids.

Research conclusions

Improper mixing of house disinfectants causes damage to the respiratory system due to chlorine poisoning. Corticosteroids may improve lung exudation, and early symptomatic supportive treatment should be performed.

Research perspectives

More case studies are required for improved generalizability and understanding of the clinical characteristics and treatment of chlorine poisoning caused by disinfectant mixing.
