Abstract

The Ultrasound Examination of the Optic Nerve Sheath Diameter in the Patients Presenting with Carbon Monoxide Poisoning: A pilot study Introduciton: In carbon monoxide poisoning, hypoxia results in neuronal damage and death of brain cells. It is considered that cerebral edema occurs consequently, with an associated increase in intracranial pressure. The present study evaluates the presence of increased intracranial pressure using the measurement of optic nerve sheath diameter by ultrasonography in the patients presenting with carbon monoxide poisoning. Methods: 28 patients diagnosed with carbon monoxide poisoning after presenting to the emergency department underwent the bilateral measurement of optic nerve sheath diameter by ultrasonography. The patients’ demographic data, laboratory results, stage of the poisoning, and optic nerve sheath diameters were recorded. Results: The median optic nerve sheath diameter in the right and left sides was greater than 5 mm. The optic nerve sheath diameter of the right and the left eye was significantly higher in the patients with severe carbon monoxide poisoning than those with moderate and mild poisoning. Conclusion: The measurement of optic nerve sheath diameter can be used to evaluate the presence of an increased intracranial pressure in the patients with carbon monoxide poisoning.
