Abstract

Increased intracranial pressure (ICP) is a severe complication of the stroke patient. The diagnosis need the equipment and invasive technique to early measure the ICP for treatment plan. Noninvasive technique such as ultrasound play the important role because we can perform it bedside, realtime and multiple. We conducted the study to apply the ONSD (optic nerve sheath diameter) ultrasound technique to monitor the ICP level of neurocritical patient. Al patients were measured the ICP by invasived device. Results: the correlation between the ONSD and the ICP with r = 0,64 (p<0,05). With the cut-off point of 5.55 mm to diagnosis the increased ICP over 20mmHg, the Se and Sp was relatively 96,4 and 62.3%. Conclusion: ONSD ultrasound is a proper technique to monitor the ICP in critical stroke patient on emergency setting.
