| shock wave | <radiobiology> Wave produced (for example, in a gas or plasma) as a result of a sudden violent disturbance. To produce a shock wave in a given region, the disturbance must take place in a shorter time than the time required for sound waves to traverse the region. (09 Oct 1997) |

| shock wave lithotripsy | A method of fragmenting calculi. (05 Mar 2000) |
| 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) |
| 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) |
