Prolonged hypoxia may result in encephalopathy, seizures, and death. Gastrointestinal Local irritation is the usual GI manifestation of hydrocarbon ingestion. Abdominal pain and nausea are common complaints. Vomiting increases the likelihood of pulmonary aspiration. Hydrocarbon toxicity has various CNS effects.
Initial effects are similar to the disinhibition seen with alcohol intoxication.
Narcotic-like depression may be seen as well. As is the case with alcohol and narcotics, a state of euphoria may develop. Eventually, lethargy, headache, obtundation and coma may follow. Seizures are uncommon but are thought to be the result of hypoxia. Cardiac Dysrhythmias are a major concern.
