Abstract

BACKGROUND: The aim of this study was to identify practice differences in the treatment of carbon monoxide (CO) poisoning with or without hyperbaric oxygen (HBO₂) therapy in Japan.

MATERIALS AND METHODS: Using an online survey website (Google form), we created a questionnaire and invited interested institutions to join the COP-J Study, a prospective observational study of CO poisoning in Japan.

RESULTS: Forty-eight (63%) of 76 institutions replied to the questionnaire. Thirty-three institutions (69%) administered HBO₂ therapy to patients with CO poisoning, and 15 institutions (31%) did not. Consciousness disturbance on arrival, exposure to CO for a long time, and elevation of arterial carboxyhemoglobin (CO-Hb) were the major indications for HBO₂ therapy. The maximum therapeutic pressures were 2.0, 2.5, and 2.8 atmospheres absolute (ATA) at 19 (58%), 6 (18%), and 8 (24%) institutions, respectively. The number of HBO₂ sessions on the first day was 1-3, and 1-7 sessions were administered on days 2-7. Seventeen (35%) institutions treated patients with delayed neurological sequelae (DNS) and 15 of them used HBO₂ therapy for DNS.

CONCLUSIONS: This survey indicates that HBO₂ therapy for CO poisoning was varied in both the indications and practice regimens used in Japan.
