In medicine, a coma (from the Greek koma, meaning deep sleep) is a profound state of unconsciousness. A comatose patient cannot be awakened, fails to respond properly or at all to stimuli such as pain or light, does not have sleep-wake cycles, and does not take voluntary actions (BAIUSA). Coma may result from a variety of conditions, including intoxication, metabolic abnormalities, central nervous system diseases, and hypoxia. Coma - Causes. An impairment that affects a large part of th ...

The Glasgow Coma Scale is used to quantify the severity of a coma. There are three components to the score: Eye opening response, Verbal response, and Motor response. In Germany, music therapy is used to quicken the awakening traject. In Belgium a project is set up to train dogs' and cats's "sixth sense" to warn patients and medical staff that a coma patient has awakened. ...

In astronomy, the nebulous envelope around the nucleus of a comet is called its coma (from the Latin word for "hair"). It is formed when the comet passes close to the sun on its highly elliptical orbit; as the comet warms, parts of it melt and/or vaporize. The coma is generally made of ice and dust. Larger dust particles are left along the comet's orbital path while smaller particles are pushed away fro

Unconsciousness, more appropriately referred to as loss of consciousness or lack of consciousness, is a dramatic alteration of mental state that involves complete or near-complete lack of responsiveness to people and other environmental stimuli. Being in a comatose state or coma is an illustration of unconsciousness. Fainting due to a drop in blood pressure and a decrese of the oxygen supply to the brain is an illustration of a temporary loss of consciousness. Loss of consciousness must not be confused with altered st ...

The Apgar score was devised in 1952 by Virginia Apgar as a simple and repeatable method to quickly and summarily assess the health of newborn children immediately after childbirth. The Apgar score is determined by evaluating the newborn baby on five simple criteria on a scale from zero to two and summing up the five values thus obtained. The resulting Apgar score ranges from zero to 10. Apgar score - Criteria. The five criteria of the Apgar score: Glasgow Coma S ...

Aberration in optical systems (lenses, prisms, mirrors or series of them intended to produce a sharp image) generally leads to blurring of the image. It occurs when light from one point of an object after transmission through the system arrives in different points. Instrument-makers need to correct optical systems to compensate for aberration. The articles reflection, refraction and caustic discuss the general features of reflected and refracted rays. Aberrations fall into two classes: chromatic aberrations ...

Diabetes mellitus is a medical disorder characterized by varying or persistent hyperglycemia (elevated blood sugar levels), especially after eating. All types of diabetes mellitus share similar symptoms and complications at advanced stages. Hyperglycemia itself can lead to dehydration and ketoacidosis. Longer-term complications include cardiovascular disease (doubled risk), chronic renal failure (it is the main cause for dialysis), retinal damage which can lead to blindness, nerve damage which can lead to erectile dysfunction (impoten ...

Some conditions share characteristics with coma and must be ruled out in a differential diagnosis before coma is conclusively diagnosed. These include locked-In syndrome, akinetic mutism and catatonic stupor. The difference between coma and stupor is that a patient with coma cannot give a suitable response to either noxious or verbal stimuli, whereas a patient in a stupor can give a crude response, such as screaming, to an unpleasant stimulus. Some psychiatric diseases appear similar to coma. Some forms of schizophrenia, catatonia, and extremely severe major depression ...

An impairment that affects a large part of the brain, called diffuse pathology, is the most common cause of coma, accounting for about 60% of the cases. To maintain consciousness, the brain requires the correct temperature, pressure, pH, oxygenation, and nutrients; denying the brain any of these necessities will lead to coma. A variety of common causes of coma can be classified as diffuse pathologies. For example, head trauma associated with an increased intracranial pressure can lead to coma by compressing delicate brain tissue, as can suba ...

Nonketotic hyperosmolar coma usually develops more insidiously than DKA because the principal symptom is lethargy progressing to obtundation, rather than vomiting and an obvious illness. Extreme hyperglycemia is accompanied by dehydration due to inadequate fluid intake. Coma from NKHC occurs most often in patients who develop type 2 or steroid diabetes and have an impaired ability to recognize thirst and drink. It is c ...

Some patients with head trauma may stabilize and other patients may deteriorate. Children with neurologic deficits may have a history of a lucid interval and relapse into coma, or they may have remained abnormal after the injury. The physocal examination will va ...
