Cushing reflex (also referred to as the vasopressor response, the Cushing effect, the Cushing reaction, the Cushing phenomenon, the Cushing response, or Cushing's Law) is a physiological nervous system response to increased intracranial pressure (ICP) that results in Cushing's triad of increased blood pressure, irregular breathing, and bradycardia. [1]
The symptoms of Cushing's disease are similar to those seen in other causes of Cushing's syndrome. [5] Patients with Cushing's disease usually present with one or more signs and symptoms secondary to the presence of excess cortisol or ACTH. [6] Although uncommon, some patients with Cushing's disease have large pituitary tumors (macroadenomas).
Intracranial pressure (ICP) and its management is a fundamental concept in traumatic brain injury (TBI). [35] The Brain Trauma Foundation guidelines recommend ICP monitoring in individuals with TBI that have decreased Glasgow Coma Scale (GCS) scores, abnormal CT scans, or additional risk factors such as older age and elevated blood pressure. [3]
The most common cause of Cushing syndrome is long-term, high-dose use of glucocorticoids, medications used to treat other medical conditions like asthma, rheumatoid arthritis, and lupus, the NIDDK ...
The expanded maternity unit is designed to handle 3,500 deliveries a year. The expansion of the heart center included two operating rooms and many cardiology upgrades allowing it to function as a fully functioning emergency cardiac treatment center. Following this, in July 2003, an $18 million project to expand the emergency room was completed. [9]
Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
A Cushing ulcer, named after Harvey Cushing, [1] [2] is a gastric ulcer associated with elevated intracranial pressure. It is also called von Rokitansky –Cushing syndrome. [ 2 ] Apart from the stomach , ulcers may also develop in the proximal duodenum and distal esophagus .
Herniation can be caused by a number of factors that cause a mass effect and increase intracranial pressure (ICP): these include traumatic brain injury, intracranial hemorrhage, or brain tumor. [1] Herniation can also occur in the absence of high ICP when mass lesions such as hematomas occur at the borders of brain compartments. In such cases ...
