They understand that you can’t shake a baby without doing harm to the baby ,but they forget all that when it comes to adult brains. Primary and secondary brain injury are ways to classify the injury processes that occur in brain injury.In traumatic brain injury (TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain. Oh, smiles, I just realized there was more to your post (and I haven’t read that yet). Ann Emerg Med.

Pathophysiology • Primary injury –Injury at the moment of impact –Caused by displacement of physical structures While public health initiatives such as seatbelts and airbags have had a major impact, it will be impossible to prevent traumatic brain injury.Therefore, it is important that we understand the pathophysiology of secondary brain injury to be able to effectively treat our patient and also to develop novel targets of future interventions. An object that penetrates brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury. This article discusses selected aspects of secondary brain injury after ICH and outlines key mechanisms associated with hematoma toxicity, oxidative stress, and inflammation. 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. 2006 Jan-Feb. 21(1):45-56. for: Medscape.

Primary brain injury The primary impact to the brain and skull may cause bony fractures, intracranial haematomas, brain contusion, axonal injury and disruption of the blood-brain barrier. Alex_Malantic. In this next lesson on TBI, we take a look at secondary brain injury. 77(5):640-5. After major brain injury, brain temperature is often higher than and can vary independently of systemic temperature. The pathophysiology of HIBI encompasses a heterogeneous cascade that culminates in secondary brain injury and neuronal cell death. Injury may result from impairment or local declines in cerebral blood flow (CBF) after a TBI. Secondary injury, which is not caused by mechanical damage, can result from the primary injury or be independent of it. [Medline]. The primary impact to the brain and skull may cause bony fractures, intracranial haematomas, brain contusion, axonal injury and disruption of the blood-brain barrier. This article discusses selected aspects of secondary brain injury after ICH and outlines key mechanisms associated with hematoma toxicity, oxidative stress, and inflammation. J Head Trauma Rehabil. Severe cases of traumatic brain injury (TBI) require neurocritical care, the goal being to stabilize hemodynamics and systemic oxygenation to prevent secondary brain injury.
