| hypovolaemic shock | A state of inadequate tissue perfusion that occurs secondary to an abnormally low circulating blood volume. May occur as the result of severe dehydration. (27 Sep 1997) |
| hypovolemic shock | A medical condition where there are abnormally low levels of blood plasma in the body, such that the body is unable to properly maintain blood pressure, cardiac output of blood, and normal amounts of fluid in the tissues. This results in a state of deep physical depression. (09 Oct 1997) |
| spinal shock | Transient depression or abolition of reflex activity below the level of an acute spinal cord injury or transection. (05 Mar 2000) |
| neurogenic shock | <neurology> This form of distributive shock results from a change in systemic vascular resistance, mediated by a neurologic injury (for example, head injury, spinal cord injury). Synonym: spinal shock. (27 Sep 1997) |
| nitroid shock | A syndrome resembling that produced by the administration of a large dose of a nitrite, sometimes caused by a too rapid intravenous injection of arsphenamine or some other drug. See: nitritoid reaction. (05 Mar 2000) |
| declamping shock | Shock or hypotension following abrupt release of clamps from a large portion of the vascular bed, as from the aorta; apparently caused by transient pooling of blood in a previously ischemic area. Synonym: declamping shock. (05 Mar 2000) |
| deferred shock | Delayed shock, a state of shock coming on at a considerable interval after the receipt of the injury. (05 Mar 2000) |
| delirious shock | Traumatic or toxic delirium following shock. Synonym: delirious shock. (05 Mar 2000) |
| dengue shock syndrome | <syndrome> Dengue fever of grade III or IV severity. (05 Mar 2000) |
| syndrome, toxic shock | A grave condition occurring predominantly in menstruating women using tampons, toxic shock is characterised by a highly toxic state (with sudden high fever, vomiting, diarrhoea, muscle aching) followed by low blood pressure (hypotension) which can lead to shock (and death). There may be a rash resembling sunburn with peeling of skin. The channing laboratory in boston under dr. Edw. Kass discovered that toxic shock was due to a toxin produced by staph (staphylococcus) aureus bacteria growing under conditions with little or no oxygen. The syndrome occurs rarely in women not using tampons and in men. (12 Dec 1998) |
| systolic shock | The abnormally palpable impact, appreciated by a hand on the chest wall, of an accentuated first heart sound. (05 Mar 2000) |
| diastolic shock | The abnormally palpable impact, appreciated by a hand on the chest wall, of an accentuated third heart sound. (05 Mar 2000) |
| distributive shock | <physiology> A form of shock (low oxygen delivery to the tissues) that results from a decline in vascular tone. This net result is pooling of unoxygenated blood in the tissues. (11 Jan 1998) |
| double-shock sound | Applied by J. B. Bouillaud to describe the cadence of a split-second heart sound, or of the second sound followed by an opening snap or early third heart sound. Synonym: double-shock sound. Origin: Fr. Drum-beat (05 Mar 2000) |
