| accidental hypothermia | Unintentional decrease in body temperature, especially in the newborn, infants, and elderly, particularly during operations. (05 Mar 2000) |
|---|---|
| regional hypothermia | Reduction of the temperature of an extremity or organ by external cold or perfusion with cold blood or solutions. (05 Mar 2000) |
| moderate hypothermia | A body temperature of 23-32캜. Induced by surface cooling. (05 Mar 2000) |
| profound hypothermia | A body temperature of 12-20캜. (05 Mar 2000) |
| hypothermia | <physiology> A low body temperature, as that due to exposure in cold weather or a state of low temperature of the body induced as a means of decreasing metabolism of tissues and thereby the need for oxygen, as used in various surgical procedures, especially on the heart or in an excised organ being preserved for transplantation. Origin: Gr. Therm = heat (11 Jan 1998) |
| hypothermia, induced | Abnormally low body temperature intentionally induced in warm-blooded animals by artificial means. (12 Dec 1998) |
| total body hypothermia | The deliberate reduction of total body temperature, in order to reduce tissue metabolism. (05 Mar 2000) |
| paradoxical | Occurring at variance with the normal rule. (18 Nov 1997) |
| paradoxical contraction | A tonic contraction of the anterior tibial muscles when a sudden passive dorsal flexion of the foot is made. (05 Mar 2000) |
| paradoxical diaphragm phenomenon | In pyopneumothorax, hydropneumothorax, and some cases of injury, the diaphragm on the affected side rises during inspiration and falls during expiration. (05 Mar 2000) |
| paradoxical embolism | Passage of a clot (thrombus) from a vein to an artery. When clots in veins break off (embolise) , they travel first to the right side of the heart and, normally, then to the lungs where they lodge. The lungs act as a filter to prevent the clots from entering the arterial circulation. However, when there is a hole in the wall between the two upper chambers of the heart (an atrial septal defect), a clot can cross from the right to the left side of the heart, then pass into the arteries as a paradoxical embolism. Once in the arterial circulation, a clot can travel to the brain, block a vessel there, and cause a stroke (cerebrovascular accident). Because of the risk of stroke from paradoxical embolism, it is usually recommended that even small atrial septal defects be repaired. Also called crossed embolism. (12 Dec 1998) |
| paradoxical extensor reflex | <clinical sign> Extension of the great toe and abduction of the other toes instead of the normal flexion reflex to plantar stimulation, considered indicative of pyramidal tract involvement ("positive" Babinski). Synonym: Babinski reflex, Babinski's phenomenon, great-toe reflex, paradoxical extensor reflex, toe phenomenon. (05 Mar 2000) |
| paradoxical flexor reflex | Dorsal flexion of the great toe produced by firm lateral pressure on the calf muscles. Synonym: paradoxical flexor reflex. (05 Mar 2000) |
| paradoxical incontinence | Involuntary loss of urine associated with overdistention of the bladder, with or without a detrusor contraction. Synonym: paradoxical incontinence. (05 Mar 2000) |
| paradoxical movement of eyelids | Spontaneous, involuntary elevation or lowering of the eyelids, associated with movement of extraocular muscles or muscles of mastication (external pterygoids). See: jaw winking. (05 Mar 2000) |
