Intracranial Pressure Monitoring: Invasive versus Non-Invasive Methods—A Review
Table 3
The different technologies compared.
| Technology | Accuracy | Rate of infection | Rate of hemorrhaging | Cost per patient | Miscellaneous |
| External ventricular drainage | High | Low to moderate | Low | Relatively low | Can be used for drainage of CSF and infusion of antibiotics | Microtransducer ICP monitoring devices | High | Low | Low | High | Some transducers have problems with high zero drift | Transcranial Doppler ultrasonography | Low | None | None | Low | High percentage of unsuccessful measurements | Tympanic membrane displacement | Low | None | None | Low | High percentage of unsuccessful measurements | Optic nerve Sheath diameter | Low | None | None | Low | Can potentially be used as a screening method of detecting raised ICP | MRI/CT | Low | None | None | Low | MRI has potential for being used for noninvasive estimation of ICP | Fundoscopy (papilledema) | Low | None | None | Low | Can be used as a screening method of detecting raised ICP, but not in cases of sudden raise in ICP, that is, trauma |
