Portable Head CT Scan and its Effect on Intracranial Pressure (ICP), Cerebral Perfusion Pressure (CPP), and Brain Oxygen

Portable computed tomography (CT) is used for the management and diagnosis of CNS diseases and acute brain injury in neuroscience ICU (NICU) such as traumatic brain injury (TBI), acute stroke, (transient ischemic stroke) TIA It will be. Subarachnoid hemorrhage (SAH). CT research is an important part of the evaluation and management of patients with brain injury. Designed for head and neck scanning, this portable device is ideal for seriously ill patients with high complications and morbidity during in-hospital shipping.

According to research I read, neuroscience nurses are involved in maintaining and managing intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in traumatic brain injury (TBI) in patients. Prevention of complications related to TBI is also generally involved in the management of care for TBI patients, such as deep venous thrombosis (DVT), hyperglycemia, and excessive protein loss. This study suggests guidelines for maintaining or mitigating ICP. Firstly, as uncontrolled intracranial hypertension leads to lack of cerebral perfusion and leads to brain death, the ICP recommended according to the initial guidelines for severe cranial brain injury management as described in this study It should be less than 20 mm Hg (Bullock, Chestnut, & Clifton, 1995). . Second, drainage of cerebrospinal fluid (CSF) - this will reduce ICP

Since CPP is the driving force of cerebral perfusion, cerebral blood flow is determined by MAP and ICP. Therefore CPP can be lowered by raising ICP or decreasing MAP. However, the brain can automatically regulate cerebral blood flow through an autoregulation process ranging from 50 to 150 mm Hg CPP. However, when the CPP value is less than 50 mmHg, the brain can not compensate for it and the cerebral blood flow and cerebral perfusion pressure decrease

Open injury treatment depends greatly on the severity of the skull fracture and the degree of brain injury. Magnetic resonance imaging (MRI), intracranial pressure monitor (ICP) or computed tomography (CT) scan helps detect obvious complications and injuries. Because victims of craniotomy are prone to infection, physicians often use antibiotics to prevent or treat infection. When an open casualties with head injuries arrive at the hospital, doctors quickly assess the visible damage of the head, such as going out and skull fractures. The doctor also measures blood pressure, body temperature, heart rate and breathing. The degree of skull and brain damage can be determined by MRI, ICP or CT scan. After identifying and evaluating fractures, the physician next determines whether the patient needs surgery and / or rehabilitation due to traumatic brain injury.
