Comparison of the Effectiveness of Treatments in Carbon Monoxide Intoxications

Carbon monoxide (CO) poisoning is a condition that occurs as a result of inhaling carbon monoxide gas and can potentially lead to serious health issues. The treatment of CO poisoning requires urgent medical intervention. Methods used in the treatment of CO poisoning include normobaric oxygen (oxygen at normal pressure), high-flow oxygen, non-invasive continuous positive airway pressure (CPAP), and hyperbaric oxygen therapy. Studies on these methods are available in the literature.

About this study

When examining the mechanisms of application for these methods:

Normobaric Oxygen Therapy: In normobaric oxygen therapy, researchers treat participants with normobaric (sea level) oxygen. This method provides high concentrations of oxygen, allowing better oxygen saturation of the blood and faster removal of carbon monoxide from the body. Participants inhale normobaric oxygen through devices such as masks or nasal cannulas.

High-Flow Oxygen Therapy: In high-flow oxygen therapy, researchers treat participants with high-flow oxygen. Typically, a nasal cannula or oxygen mask is used. The high flow rate allows more oxygen to reach the alveoli and bind to hemoglobin. This method can be effective, especially in more severe cases of carbon monoxide poisoning.

Non-Invasive CPAP Therapy: Non-invasive CPAP therapy is typically used to treat respiratory problems such as sleep apnea but can also be used in the treatment of CO poisoning. Participants receive oxygen under continuous positive airway pressure with the help of a mask.

Comparison of these methods:

Normobaric oxygen is considered the standard treatment for CO poisoning and generally effectively eliminates carbon monoxide from the body. High-flow oxygen may be more effective in providing additional oxygen in more severe cases, but it works similarly to normobaric oxygen. The choice of which treatment method to use can vary depending on the participant's clinical condition, the severity of poisoning, and other factors. The researchers main goal in designing this study is to determine which treatment, depending on the researcher's decision, most rapidly shortens the half-life of carbon monoxide in participants experiencing severe carbon monoxide poisoning.The researchers aim to identify which treatment participants tolerate better and which method minimizes complications related to CO intoxication.

Treatment and study plan

Primary outcomes

  1. Carboxyhemoglobin

    Time frame: 6 hours later

    Blood carboxyhemoglobin saturation is typically expressed as a percentage. For example, the statement "blood carboxyhemoglobin saturation is 5%" indicates that 5% of hemoglobin has been converted to carboxyhemoglobin. This ratio affects the oxygen-carrying capacity of the blood and serves as an indicator of carbon monoxide poisoning. After treatment, a decrease in this ratio signifies the elimination of carbon monoxide from the body and the restoration of normal oxygen-carrying function.

  2. lactate

    Time frame: 6 hours later

    Blood lactate levels are typically measured in millimoles per liter (mmol/L)
