The Trousseau sign of latent tetany is another sign of decreased calcium in blood where muscles in the hand contract when the brachial artery supplying the area is occluded. The Trousseau sign of latent tetany also generally occurs earlier than the Chvostek sign and is a more accurate predictor of hypocalcemia, allowing clinicians to recognise ...
Trousseau sign of latent tetany is a medical sign observed in patients with low calcium. [1] From 1 to 4 percent of normal patients will test positive for Trousseau's sign of latent tetany. [ 2 ] This sign may be positive before other manifestations of hypocalcemia such as hyperreflexia and tetany , as such it is generally believed to be more ...
Trousseau sign of latent tetany (eliciting carpal spasm by inflating the blood pressure cuff and maintaining the cuff pressure above systolic) Chvostek's sign (tapping of the inferior portion of the cheekbone will produce facial spasms) [8] Tendon reflexes are hyperactive; Life-threatening complications Cardiac arrhythmias; Effects on cardiac ...
Trousseau described several cases in which recurrent thrombosis was the presenting feature of visceral cancer, and his confidence in the utility of this connection led him to say, "So great, in my opinion, is the semiotic value of phlegmasia in the cancerous cachexia, that I regard this phlegmasia as a sign of the cancerous diathesis as certain ...
Chvostek sign: František Chvostek: endocrinology: hypocalcemia: tapping over facial nerve elicits abnormal muscle contraction(s) Claybrook sign: Edwin Claybrook: emergency medicine, surgery: blunt abdominal trauma: heart and/or breath sounds heard through abdominal wall indicate rupture of viscus Clutton's joints: Henry Hugh Clutton ...
This is now known as the Trousseau sign of latent tetany. [8] Also, tetany can be demonstrated by tapping anterior to the ear, at the emergence of the facial nerve. A resultant twitch of the nose or lips suggests low calcium levels. This is now known as the Chvostek sign. [citation needed]
Physical examination of someone with hypocalcemia may show tetany, but it is also possible to provoke tetany of the facial muscles by tapping on the facial nerve (a phenomenon known as Chvostek's sign) or by using the cuff of a sphygmomanometer to temporarily obstruct the blood flow to the arm (a phenomenon known as Trousseau's sign of latent ...
Trousseau sign is the name of two distinct phenomena observed in clinical medicine. Both are attributed to Armand Trousseau: Trousseau sign of latent tetany;
