[Correlations between intracranial pressure (I.C.P.) and EEG changes during traumatic coma (author's transl)]
Summary
Intracranial pressure (ICP) monitoring in comatose patients reveals EEG changes correlating with ICP fluctuations. Specific EEG patterns indicate ICP instability and potential increases, offering insights into brain injury management.
Area of Science:
- Neurology
- Neurophysiology
- Critical Care Medicine
Context:
- Comatose patients following cranial injuries are studied.
- Polygraphic recordings including ICP, EEG, EMG, EOG, Respiration, and ECG were performed.
- Recordings were conducted during the week post-injury.
Purpose:
- To investigate the relationship between intracranial pressure (ICP) and electroencephalogram (EEG) activity.
- To identify EEG patterns indicative of ICP fluctuations and brain injury severity.
Summary:
- Stable ICP without waves correlated with slow, nonreactive EEG.
- Lundberg's B waves on ICP recordings corresponded to alternating slow and rapid EEG activity.
- EEG flattening preceded ICP increases, while slow wave reappearance indicated ICP decrease.
Impact:
- Provides a correlation between EEG and ICP dynamics in traumatic brain injury.
- Suggests EEG can serve as a non-invasive indicator of intracranial pressure changes.
- Informs clinical monitoring and management strategies for comatose patients with head injuries.

Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
