Trousseau sign

from Wikipedia, the free encyclopedia

The Trousseau's sign is a clinical indication of a tetany , for example in the context of hypoparathyroidism .

If, after inflating a blood pressure cuff above the systolic blood pressure , the hand is in a pawl position , latent tetany due to calcium deficiency ( hypocalcemia ) can be assumed. The paw position consists of a spastic contraction of the finger flexors and hand muscles.

The Trousseau's sign has low sensitivity and specificity , but it is very easy to check and, like the Chvostek's sign and the Faust sign , can be used for medical monitoring of the patient, for example after resection of the thyroid gland .

It is named after the French internist Armand Trousseau (1801–1867).
