This prospective cohort study enrolls subjects who experience carbon monoxide (CO) poisoning. The purpose of the study is to evaluate therapeutic effects of various treatments and short and long-term outcomes in CO poisoned patients. In addition, complications of brain and heart susceptible to CO are investigated through various ways and the association between complications and the patient's prognosis is also investigated. All subjects will be regularly monitored by physicians participating in this study.
This prospective cohort study enrolls subjects who experience CO poisoning. The purpose of the study is to evaluate therapeutic effects of various treatments, including hyperbaric oxygen therapy (HBO), therapeutic hypothermia (TH), and additional drugs, and short and long-term outcomes, such as neurocognitive sequelae or mortality, in CO poisoned patients. In addition, complications of brain and heart susceptible to CO are investigated through a variety of ways, such as magnetic resonance image (MRI), computed tomography (CT), ultrasound, and laboratory test, and the association between various complications and the patient's prognosis is also investigated. All subjects will be regularly monitored by physicians participating in this study.
