To date there exists no sensible way of classifying the intensity of haemorrhage following tonsillectomy, though this is a prerequisite when comparing the results presented in literature. We evaluated the incidence of post-operative haemorrhage according to our classification in 602 patients who underwent tonsillectomy at our department in 1999.Definition and Effects of Haemorrhage: Escape of blood, from ruptured blood vessels is called haemorrhage. The effects of haemorrhage depend on the amount and rapidity of blood loss, and the efficiency of the compensatory power of the subject. If the haemorrhage be severe it may lead to circulatory collapse and death.A haemorrhagic stroke or cerebral haemorrhage is a stroke that is caused by a bleed on the brain. Although they are less common than ischaemic strokes, they can be much more serious. A haemorrhagic stroke is a stroke that is caused by bleeding in or around the brain.
Bleeding, also known as a hemorrhage or haemorrhage, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a wound in the skin.
CLASSIFICATION: Strokes can be classified into two major categories: ischemic and hemorrhagic. Ischemia is due to interruption of the blood supply, while hemorrhage is due to rupture of a blood vessel or an abnormal vascular structure. 80% of strokes are due to ischemia; the remainders are due to hemorrhage (Donnan GA, Fisher M. May 2008).
Stroke is a term describe the sudden onset of a constant neurological deficit caused by partial or complete obstruction (ischemic stroke) or rupture of a cerebral blood vessel (haemorrhage). (1) Stroke is the second most common cause of morbidity worldwide and is the primary cause.
Long-term compensation for haemorrhage occurs by several mechanisms: reduced glomerular filtration rate; salt and water reabsorption (aldosterone and vasopressin); thirst; increased erythropoiesis. Haemorrhagic shock causes a significant lactic acidosis; once the mitochondrial PO2 is less than 2 mmHg, oxidative phosphorylation is inhibited and pyruvate is unable to enter the Krebs cycle.
This is a basic article for medical students and other non-radiologists. Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space.This is usually found centrally (around the circle of Willis) but can occur in other parts of the brain.
At one stage in the history of neurology and neurosurgery, subarachnoid haemorrhage scoring systems had proliferated wildly and at one stage there were apparently about 40 of them. Major criticisms of these older systems were subjective measures, retrospective methodology and poor inter-rater reliability. More recent systems (if you can call them that, from the 1980s) have been generally.
A Subarachnoid Hemorrhage, or SAH, is devastating and usually has a traumatic outcome. Basically, an SAH is bleeding that occurs between the brain and what surrounds it. This surrounding area is known as the arachnoid, thus the reasoning behind the name. The main cause of SAH is cerebral, or brain.
The 2012 revised Atlanta classification is an update of the original 1992 Atlanta classification, a standardized clinical and radiologic nomenclature for acute pancreatitis and associated complications based on research advances made over the past 2 decades. Acute pancreatitis is now divided into two distinct subtypes, necrotizing pancreatitis.
An assay is an investigative (analytic) procedure in laboratory medicine, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity (the analyte). The analyte can be a drug, biochemical substance, or cell in an organism or organic sample.
Postoperative bleeding following abdominal surgery is relatively rare and mainly depends on the type of surgery. Although bleeding is usually controlled by simple local treatment of symptoms, specific treatment including surgery or interventional radiology is sometimes necessary.
Classes of the American College of Surgeons (ACS) for Acute Hemorrhage Purpose: To categorize the blood loss from a patient using the American College of Surgeons (ACS) classification system.
James Parkinson’s Essay on the Shaking Palsy SHAKING PALSY. (Paralysis agitans) Involuntary tremulous motion, with lessened muscular power, in parts not in action and even when supported; with a propensity to bend the trunk forward and to pass from a walking to a running pace: the senses and intellects being uninjured.
The prior aneurysmal subarachnoid hemorrhage (aSAH) guidelines, sponsored by the AHA Stroke Council, were previously issued in 1994 1 and 2009. 2 The 2009 guidelines covered literature through November 1, 2006. 2 The present guidelines primarily cover literature published between November 1, 2006, and May 1, 2010, but the writing group has.
Classification and Division: Vacations Vacations are something nine-to-fivers look forward to every year. They can be an escape from the office, a way to take the family somewhere new, or just a moment’s peace from the daily grind.
