Hazards and Protection.
Nausea and vomiting may occur. Metabolic acidosis may develop secondary to tissue hypoxia.
Dyspnea and tachypnea may occur. CNS effects include headache, dizziness, altered mental status, confusion, lethargy progressing to coma seizures and syncope; these occur secondary to CNS hypoxia, usually with levels > 20 percent.
Central cyanosis unresponsive to oxygen therapy is classic.
Causes severe irritation.
Administer charcoal as a slurry (240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old Consider gastroc ;avage after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in Trendelenburg and left lateral decubitus position or by endotracheal intubation. Control any seizures first.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, for respiratory tract irritation bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids.
Skin should be thoroughly washed with soap and water. Contaminated clothing and shoes should be discarded Seek medical attention. Administer 100 percent humidified supplemental oxygen with assisted ventilation as required. Treat for methemoglobinemia and sequelae. Signs and symptoms of methemoglobinemia may be delayed.
Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
