Increased intracranial pressure is usually measured with invasive methods that are not practical in resource-limited countries. However, bedside ultrasound, a non-invasive method, measures the optic nerve sheath diameter and could be a safe and accurate alternative to measure intracranial pressure, even in children.
We report a case of a 15-year old patient who presented with severe headache, projectile vomiting, and neck pain for two months. The bedside ultrasound showed a 10 mm optic nerve sheath diameter and a Computed Tomography scan of her brain revealed obstructive hydrocephalus secondary to a mass in the fourth ventricle. After intervening, we were able to monitor the decrease in her optic nerve sheath diameter with ultrasound.
Performing invasive procedures continues to be a challenge in the resource limited setting. However, bedside ultrasound can be a useful tool in emergency centres for early detection and monitoring of intracranial pressure.
颅内压升高通常采用侵入性方法测量，而这种方法在资源有限的国家并不实用。然而，床旁超声作为一种非侵入性方法，可测量视神经鞘直径，甚至对于儿童而言，也可能是一种安全且准确的测量颅内压的替代方法。
我们报告一例15岁患者，其出现严重头痛、喷射性呕吐及颈部疼痛达两个月。床旁超声显示视神经鞘直径为10毫米，其脑部计算机断层扫描显示第四脑室肿物继发梗阻性脑积水。干预治疗后，我们能够通过超声监测其视神经鞘直径的减小情况。
在资源有限的环境中，进行侵入性操作仍然是一项挑战。然而，床旁超声在急诊中心可成为早期检测和监测颅内压的有用工具。
