Description

In emergency rooms, Traumatic Brain Injuries (TBI) is a common issue. Brain death, which is the end of the medical scenario, is one of the difficulties that follow cerebral bleeding occurrences and has drawn attention. However, 70 to 80 percent of head injuries are benign, causing no harm to the brain or its function, and they heal on their own with conservative measures. Head trauma is becoming more and more frequent in individuals between the ages of 21 and 30 due to its recent increase in occurrence. Epidural Haemorrhage (EDH), Subdural Haemorrhage (SDH), Subarachnoid Haemorrhage (SAH), and Intraventricular Haemorrhage (IVH) are just a few of the different types of intracranial haemorrhage. By contusion or midline shift, the clinical prognosis of head traumatic hemorrhagic lesions may deteriorate. The Uniform Determination of Death Act (UDDA) guidelines define the diagnosis of brain death as an irreversible loss of brain function brought on by whole-brain trauma. Lack of response, lack of motion, and brain stem reflexes that support the patient's comatose state are among the bedside examinations used to confirm brain death. It should be kept in mind that sedative drug usage, hypothermia, hypotension, or metabolic problems must all be ruled out or treated before a diagnosis of brain death is made. The brain's neural stem's ability to recognise the absence of respiratory drive is evaluated by an apnea test.

Critical paraclinical evidence that supports the brain death event is regarded to be insufficient blood supply to the brain. Although CT scan is a helpful tool in the diagnosis of brain death, brain CT angiography is superior to it (with a sensitivity of 76%). Subarachnoid hemorrhage, a common kind of Intracerebral Haemorrhage (ICH), makes up 0.47 percent of the top causes of death in Iran and 0.8 percent of the top causes of death worldwide, according to health statistics reports on the global burden of illnesses. The early detection and necessary therapies according to the type of cranial haemorrhage determine the clinical outcome and final prognosis when taking into account the peculiar consequences resulting from traumatic brain injury on patients. It would be adequate if the frequency of brain death, the final stage of brain injury, decreased. Unfortunately, there aren't enough reports on the many cranial haemorrhages that cause brain death in head injury victims. The most frequent cerebral hemorrhagic brain death subjects were SAH and SDH, which had varying incidence rates of sequelae.

On the prevalence of SAH, SDH, EDH, ICH, and brain edoema equal to 0.74%, 10.39%, 7.92%, and 3.21% in head trauma patients. It is possible for sources of elevated Intracranial Pressure (ICP), such as brain tumours and intracranial hemorrhages, to result in midline shift, a potentially fatal event. A serious consequence that could arise from cerebral haemorrhage episodes is edoema. Compared to SAH patients, SDH participants showed a higher incidence of cerebral edoema. Physicians gained a thorough understanding of the main causes of death and disability in their communities with the aid of epidemiologic investigations. Head severe intracranial haemorrhage is the most frequent type of hemorrhagic event in these situations, bearing a substantial weight of brain death and serving as its primary cause in emergency clinical settings.

The most frequent cerebral hemorrhagic episodes in people who have experienced brain death are SAH and SDH, with varied incidence rates and prognoses. TBI victims may experience health issues for a few days or the rest of their life, depending on the severity of the injury. For instance, a person with a minor Traumatic Brain Injury (TBI) or concussion could experience transient symptoms before feeling better within a few weeks or months. Additionally, a person who has suffered a moderate or severe TBI could be left with permanent repercussions from the damage. Compared to all other age groups, older persons are more likely to require hospitalization and pass away from a TBI. However, because TBI symptoms coincide with those of other medical illnesses that are frequent in older persons, such as dementia, TBIs may be ignored or incorrectly diagnosed in older adults.
