The primary, secondary, and tertiary brain injury
Traumatic brain injury TBI is one of the most prevalent causes of morbidity and mortality all over the world. The knowledge and understanding of pathophysiology of TBI are the priority as a basic to develop therapeutic opportunities and allow improvement of outcome for TBI patients. In TBI, primary damage occurs at the time of impact and the damage is preventable but not treatable. The process will continue caused following trauma due to complicating processes. Secondary brain insults have been found in many patients of severe TBI. This insult continues, which involves complex molecular and genes cascades, and is not fully understood.

Traumatic Brain Injury TBI is a disruption in the normal function of the brain that can be caused by a blow, bump or jolt to the head, the head suddenly and violently hitting an object or when an object pierces the skull and enters brain tissue. Observing one of the following clinical signs constitutes alteration in the normal brain function:.
Primary and secondary brain injury
Traumatic brain injury TBI remains one of the leading causes of morbidity and mortality amongst civilians and military personnel globally. Despite advances in our knowledge of the complex pathophysiology of TBI, the underlying mechanisms are yet to be fully elucidated. While initial brain insult involves acute and irreversible primary damage to the parenchyma, the ensuing secondary brain injuries often progress slowly over months to years, hence providing a window for therapeutic interventions. To date, hallmark events during delayed secondary CNS damage include Wallerian degeneration of axons, mitochondrial dysfunction, excitotoxicity, oxidative stress and apoptotic cell death of neurons and glia. Extensive research has been directed to the identification of druggable targets associated with these processes.
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. Primary and secondary injuries occur in instances other than a TBI, such as spinal cord injury and stroke. In TBI, primary injuries result immediately from the initial trauma. Secondary injury is an indirect result of the injury. It results from processes initiated by the trauma.

Traumatic brain injured still represents the leading cause of morbidity and mortality in individuals under the age of 45 years in the world. The classification of secondary brain injured is divided into extracranial and intracranial causes. The cause of extracranial such as hipoxia, hypotensi, hyponatremia, hypertermia, hypoglycemia or hyperglycemia. The cause of intracranial such as extradural, subdural, intraserebral, intraventrikular, dan subarachnoid hemorrhage. Beside that secondary injury can also be caused by edema and infection.

Metrics details. Severe cases of traumatic brain injury TBI require neurocritical care, the goal being to stabilize hemodynamics and systemic oxygenation to prevent secondary brain injury. For this reason, neurocritical care is incomplete if it only focuses on prevention of increased intracranial pressure ICP or decreased cerebral perfusion pressure CPP.
Mechanisms of Secondary Brain Damage pp Cite as. The outcome of head injury in the human depends upon the interaction of pre-injury factors, the nature of the injury to the skull and brain and secondary factors that lead to further brain dysfunction and damage Miller and Becker, The important pre-injury factors are age, the psychosocial status of the patient and state of health prior to injury, in particular previous brain injury, hydrocephalus or stroke.
Он опустил глаза и посмотрел на ее протянутую руку. - Речь идет о засекреченной информации, хранящейся в личном помещении директора. Ты только представь себе, что будет, если об этом станет известно. - Директор в Южной Америке. - Извини. Я не могу этого сделать.
Нет. - Он усмехнулся. - Я попросил Фонтейна передать его наследникам Танкадо. - Он взял ее руку и натянул что-то на палец. - Лжец, - засмеялась Сьюзан, открывая .
Беккер достал из кармана бумажник. - Конечно, я буду счастлив тебе заплатить. - И он начал отсчитывать купюры.
