ABSTRACT
BACKGROUND:
Optic nerve sheath diameter (ONSD) sonography has been proposed as a reliable bedside tool for the detection of increased intracranial pressure (ICP). ONSD reacts almost simultaneously to oscillations in ICP. The aim of this study was to investigate the ONSD dynamics in the acute stage of intracerebral hemorrhage (ICH) and to compare ONSD dynamics to the clinical outcome.METHODS:
We enrolled 35 acute ICH patients and 20 healthy volunteers in this prospective study. At the admission, all patients underwent brain CT scan and ONSD sonography. We repeated the ONSD on the second and the third day in all patients while CT scan was repeated if a patient condition deteriorated. The changes in serial ONSD measurements were termed as stable or unstable ONSD trend. ONSD trend was considered as unstable if variations of average ONSD were above 5%. The outcome of the patient was assessed with the Modified Rankin Scale (mRS) and Glasgow Outcome Scale (GOS).RESULTS:
In healthy volunteers serial ONSD recordings for 3 days revealed a stable trend in 100%. However, in the study group, 23 patients had unstable and 12 had stable ONSD trend during the acute stage of ICH. The patients with unstable ONSD trend were more likely to have worse outcomes (p value 0.003).CONCLUSION:
In patients with ICH, the acute-phase ONSD dynamics can help in predicting the clinical outcome.
