| glasgow coma scale | A scale that assesses the degree of coma in patients with craniocerebral injuries; also assesses brain function, brain damage, and patient progress. (12 Dec 1998) |
|---|---|
| metabolic coma | Coma resulting from diffuse failure of neuronal metabolism, caused by such abnormalities as intrinsic disorders of neuron or glial cell metabolism, or extracerebral disorders that produce intoxication or electrolyte imbalances. (05 Mar 2000) |
| coma | A deep prolonged unconsciousness where the patient cannot be aroused. This is usually as the result of a head injury, neurological disease, acute hydrocephaly, intoxication or metabolic derangement. (27 Sep 1997) |
| coma aberration | The distortion of image formation created when a bundle of light rays enters an optical system not parallel to the optic axis. <botany> Any tuft, as the hairs on a seed, or the greenery on a radish or a pineapple. Synonym: coma. Origin: G. Kome, hair, foliage (05 Mar 2000) |
| coma carcinomatosum | Coma occurring in the final stage of cancerous cachexia. (05 Mar 2000) |
| coma cast | A renal cast of strongly refracting granules said to be indicative of imminent coma in diabetes. Synonym: Kulz's cylinder. (05 Mar 2000) |
| coma scale | A clinical scale to assess impaired consciousness; assessment may include motor responsiveness, verbal performance, and eye opening, as in the Glasgow (Scotland) c.s., or the same three items and dysfunction of cranial nerves, as in the Maryland (U.S.) c.s. (05 Mar 2000) |
| coma vigil | Subacute or chronic state of altered consciousness, in which the patient appears alert intermittently, but is not responsive, although his/her descending motor pathways appear intact; due to lesions of various cerebral structures. Synonym: coma vigil. (05 Mar 2000) |
| hepatic coma | A condition of severe end-stage liver dysfunction that is accompanied by unresponsiveness (coma). A feature of hepatic encephalopathy. (27 Sep 1997) |
| hyperglycaemic hyperosmolar nonketotic coma | A syndrome consisting of extreme hyperglycaemia, serum hyperosmolarity and dehydration in the absence of ketosis and acidosis. (12 Dec 1998) |
| hyperosmolar nonketotic coma | A complication seen in diabetes mellitus in which very marked hyperglycaemia occurs (such as levels over 800 mg/dL) causing osmotic shifts in water in brain cells and resulting in coma. It can be fatal or lead to permanent neurologic damage. Ketoacidosis does not occur in these cases. Synonym: nonketotic hyperglycaemia. (05 Mar 2000) |
| hypoglycaemic coma | A metabolic encephalopathy caused by hypoglycaemia; usually seen in diabetics, and due to exogenous insulin excess. (05 Mar 2000) |
| hypoventilation coma | Coma seen with advanced lung failure and resultant hypoventilation. Synonym: CO2 narcosis, hypoxic-hypercarbic encephalopathy, pulmonary encephalopathy. (05 Mar 2000) |
| delayed coma after hypoxia | Coma that develops a few days to 3 weeks after an acute hypoxic insult; the latter was usually severe enough to cause an initial bout of coma, which cleared, and was followed by a transient interval of apparent normality. Synonym: severe postanoxic encephalopathy. (05 Mar 2000) |
| diabetic coma | A severe metabolic derangement that occurs in the absence of insulin. Insulin allows the body to absorb glucose into cells for energy production. In the absence of insulin, the body starts to break down fats for fuel. A metabolic byproduct of fat metabolism is referred to as a ketone. The presence of elevated blood ketones in this setting is known as diabetic ketoacidosis. In extreme, untreated cases, this can lead to coma and death. (27 Sep 1997) |
