Thailand studying electrical engineering at the university. He was ejected from a moving vehicle, which was traveling 70 mph. His injuries included a severe closed head injury with an occipital hematoma, bilateral wrist fractures, and a right pneumothorax. During his neurologic intensive care unit (NICU) stay, Y. W. was intubated and placed on mechanical ventilation, had a feeding tube inserted and was placed on tube feedings, had a Foley catheter to down drain (DD), and had multiple IVs inserted. He developed pneumonia 1 month after admission.
Closed head injuries result from a blow to the head as occurs, for example, in a car accident when the head strikes the windshield or dashboard. These injuries cause two types of brain damage. 1. Define the term primary head injury. A primary head injury (or primary impact) is also known as a “coup injury. ” The injury occurs under the site of impact with an object such as a hammer or a rock. The brain strikes the skull after the head strikes the object of impact (Lewis, et al, Fig 57-14).
This is the site of the direct impact of the brain on the skull.
Often there is edema around the site of impact. 2. Define the term secondary head injury. The secondary head injury is also known as contrecoup injury occurs on the side opposite the area that was impacted. These injuries tend to be more severe and overall patient prognosis depends on the amount of bleeding around the contusion site (Lewis, et al, 1425).
The Essay on Impact of Strike in an Organization
The impact of strike to an organization Article by Rajalakshmi Rahul on June 11, 2012 Discuss now (0) Go to comments An organizational strike not only destroys the power of labor at its source while still professing theoretical support for the right to strike, but also causes many other losses. Labor on the other hand in demanding freedom to use the organizational strike is seeking an instrument ...
Often it is the secondary brain injuries that show few initial symptoms and then have serious side effects days to weeks later. 3. What is normal intracranial pressure (ICP), and why is increased ICP so clinically important?
Normal intracranial pressure ranges from 5 to 15 mm Hg. A sustained pressure above the upper limit is considered abnormal. Pressure changes in the brain effect the brain’s compliance. Compliance is the “expandability of the brain” With low compliance, small changes in volume occur and result in greater increases in pressure. Elevated intracranial pressure is clinically significant because “it diminishes CPP, increases risks of brain ischemia and infarction, and is associated with a poor prognosis”.
