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 ...
Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L ), while levels less than 2.1 mmol/L are defined as hypocalcemic.
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 ...
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 ...
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 ...
Trousseau sign is the name of two distinct phenomena observed in clinical medicine. Both are attributed to Armand Trousseau: Trousseau sign of latent tetany;
Neurological and cardiovascular symptoms are the most common manifestations of hypocalcemia. [3] [14] Patients may experience muscle cramping or twitching, and numbness around the mouth and fingers. They may also have shortness of breath, low blood pressure, and cardiac arrhythmias. [3]
