There is no such thing as a "preferred method for treating acute carbon monoxide poisoning." Treatment methods for acute carbon monoxide poisoning include immediate removal from the contaminated environment, maintaining airway patency, hyperbaric oxygen therapy, symptomatic and supportive treatment, and correction of acid-base imbalances. The core principle is rapid removal from the source of exposure and promoting dissociation of carboxyhemoglobin. If severe symptoms such as coma, difficulty breathing, or low blood pressure occur, immediate medical attention is recommended.
1. Immediate removal from the contaminated environment: Quickly move the patient to a place with fresh, well-ventilated air. Loosen the collar and belt to ensure unobstructed breathing and prevent continued inhalation of carbon monoxide, which could worsen poisoning symptoms.
2. Maintain airway patency: Clear secretions and vomit from the patient’s mouth and nose. If respiratory depression occurs, provide artificial respiration or assisted ventilation promptly to ensure effective oxygen delivery into the body.
3. Hyperbaric oxygen therapy: This is a key treatment approach. By increasing blood oxygen partial pressure under high-pressure conditions, it accelerates the dissociation of carboxyhemoglobin, promotes elimination of carbon monoxide, reduces brain tissue damage, and lowers the risk of long-term complications.
4. Symptomatic and supportive treatment: Administer sedatives and anticonvulsants for patients experiencing seizures or coma; correct hypotension and arrhythmias; protect vital organ functions (such as heart, brain, and kidneys); and prevent complications.
5. Correction of acid-base imbalance: Carbon monoxide poisoning may lead to metabolic acidosis. Intravenous fluid administration and other measures should be used to restore acid-base balance and maintain electrolyte stability, creating favorable conditions for recovery of organ function.
During recovery, patients should get adequate rest and avoid physical exertion and emotional excitement. A light, easily digestible diet rich in high-quality protein is recommended. Ensure good indoor ventilation, avoid re-exposure to carbon monoxide sources such as gas or charcoal fires, and regularly monitor health status.
