What are the symptoms of benzene poisoning?

Benzene poisoning is a very dangerous thing. Sometimes it can directly threaten life. Patients with acute benzene poisoning will show symptoms such as dizziness, dazzling, tinnitus, or convulsions, coma, and respiratory central nervous system paralysis.

(1) Nervous system symptoms include headache, dizziness, tinnitus, diplopia, unsteady gait, feeling of being drunk, drowsiness, and in severe cases, convulsions, coma, paralysis of the respiratory center, delirium, hallucinations, and cerebral edema. A small number of patients experience peripheral nerve damage. This condition can further develop into increased confusion and a state of light coma, in which the patient becomes unresponsive to calls. Continuing to inhale high concentrations of benzene can lead to a deep coma. In severe cases, breathing and cardiac arrest may occur. The course of the disease depends on the concentration of benzene in the air, which can last from minutes to hours. Active rescue before cardiac arrest can restore the patient's condition within minutes to hours. If a deep coma occurs, people who inhale high concentrations may die like lightning.

(2) Respiratory system problems are seen in inhalation poisoning, with symptoms such as coughing, shortness of breath, and chest tightness. In severe cases, the symptoms may last for a long time, or when breathing is weak, hypoxic pulmonary edema may occur, which may be accompanied by eye irritation symptoms.

(3) The circulatory system may experience flushing, palpitations, and a drop in blood pressure, which may lead to shock, myocarditis, various arrhythmias, and even ventricular fibrillation. The electrocardiogram showed first to second degree atrioventricular block.

(4) Nausea, vomiting, and abdominal pain in the digestive system. Symptoms are more severe in patients taking oral medication. Occasionally, hepatomegaly and elevated aminotransferase levels may occur. Acute poisoning mainly causes toxic anesthesia, a process similar to general anesthesia during drunkenness or surgery.
