3203: The change of optic nerve sheath diameter (ONSD) after treatment in increased ICP patients

Abstract

Objectives: There have been no studies analyzing the ONSD related to the patients’ outcome after proper treatment. We evaluated the ONSDs of the patients suspected of increased ICP at the emergency center and analyzed the changes of the ONSDs after the management.Methods: During the 10 mo, we recruited 29 patients who were suspected of increased ICP by the initial computed tomography. After 7 days of admission, neurological status and ONSDs were re-evaluated and compared with the previous data.Results: Total of 29 patients were enrolled. Glasgow Coma Scale (GCS) score at the admission was mean 7.86 ± 3.60. 18 patients showed improved neurological outcomes and 11 showed either no significant changes or worsened outcomes. The initial mean ONSD was 5.41 ± 0.70 mm. The mean ONSD after 7 days of admission showed a significant decrease as compared to the initial measurements (p < 0.05). Patients with improved neurological outcomes had a mean GCS of 13.44 ± 2.15 and mean ONSD of 4.13 ± 0.40 mm, which revealed to be significantly different from the rest of the patients (GCS 3.82 ± 3.82, ONSD 4.86 ± 0.37 mm, p < 0.05).Conclusions: The ONSDs of the patients with increased ICP who had the good neurological outcomes after treatment showed the significantly smaller ONSDs than those of the patients with poor outcomes.
