This article discusses selected aspects of secondary brain injury after ICH and outlines key mechanisms associated with hematoma toxicity, oxidative stress, and inflammation. 2020 Feb 26. 1982 Mar. 1:6-18. This is because the higher the ICP gets, the more resistance the mean arterial pressure (MAP) in the body has to face in order to get oxygenated blood from the heart into the brain for perfusion. Grauwmeijer E, Heijenbrok-Kal M, Peppel L, et al. Parcell DL, Ponsford JL, Rajaratnam SM, et al. Secondary brain injury is defined as any subsequent injury to the brain after the initial injury. As one might imagine, having a poorly perfused brain is bad enough, but having it poorly perfused with poorly oxygenated blood is even worse. The Biological Basis of Chronic Traumatic Encephalopathy following Blast Injury: A Literature Review. As discussed above, increased ICP can be compensated for in three ways: There are three cornerstone approaches to the management of secondary brain injury: To achieve all of these interventions in order to prevent decompensation, these patients are often managed in an intensive care unit. Traumatic brain injury (TBI) is one of the most prevalent causes of morbidity and mortality all over the world.

Therefore, it is the blood and CSF that needs to be displaced out of the brain vault to maintain equilibrium. Chronic traumatic encephalopathy in athletes: progressive tauopathy after repetitive head injury. Recent advances in pathophysiology of traumatic brain injury. Decreases in CBF are the result of local edema, hemorrhage, or increased intracranial pressure (ICP).

If the pathophysiological process of the secondary brain injury is too severe, additional interventions may be required to help with compensation: The insertion of an external ventricular drain (EVD) via a ventriculostomy to help drain excess CSF from the brain vault and additionally monitor ICP, A craniotomy to remove a portion of the skull to allow for excessive swelling of brain tissue.

Caplain S, Blancho S, Marque S, Montreuil M, Aghakhani N. Early Detection of Poor Outcome after Mild Traumatic Brain Injury: Predictive Factors Using a Multidimensional Approach a Pilot Study. There are many causes that can result in increased ICP including: Oedema and swelling that requires time to decrease, Intracranial haemorrhage that requires immediate surgical evacuation if it is large or time to reabsorb if it is smaller, Brain tumour that requires surgical intervention to remove, if possible, Maintain temperature between 35 – 37 degrees to reduce cerebral metabolic demands, Increased ICP can lead to an increased risk of seizures, Seizures further increase ICP and cerebral metabolic demands and therefore should be actively prevented, if possible, Maintain even balance for the patient and ensure that electrolytes are within their normal ranges, If intravascular filling is required, colloids should be avoided due to studies showing an increased mortality when used in patients with neurological pathophysiology, Cerebral oedema can be reduced by utilising Mannitol to shift fluid from the intracellular cerebral tissue into the intravascular space, which can then be removed from the body by utilising a diuretic such as Frusemide.
