What does a positive Trousseau sign mean?
What does a positive Trousseau sign mean?
The Trousseau sign of latent tetany is a way to determine if an individual may have hypocalcemia. Trousseau’s sign is considered positive when a carpopedal spasm of the hand and wrist occurs after an individual wears a blood pressure cuff inflated over their systolic blood pressure for 2 to 3 minutes.
What is Chvostek’s sign and Trousseau’s sign?
Chvostek’s sign is de- scribed as the twitching of facial muscles in response to tapping over the area of the facial nerve (Video 1). Trousseau’s sign is carpopedal spasm that results from ischemia, such as that induced by pressure applied to the upper arm from an in- flated sphygmomanometer cuff (Video 2).
How do you assess Trousseau’s sign?
Test for the Trousseau sign by placing a blood pressure cuff on the patient’s arm and inflating to 20 mm Hg above systolic blood pressure for 3-5 minutes.
What causes Chvostek’s sign?
The Chvostek sign aims to elicit an atypical reaction of the facial nerve, the nerve that innervates many of the muscles of the face. The pressure caused by the tapping acts as a triggering stimulus for involuntary contractions of the facial muscles ipsilaterally, or on the side that the clinical sign is performed.
What is the classic sign of hypocalcemia?
Symptoms of hypocalcemia most commonly include paresthesia, muscle spasms, cramps, tetany, circumoral numbness, and seizures.
What is positive sign of hypocalcemia?
Ipsilateral contraction of the facial muscles is a positive sign. Depending on the calcium level, a graded response will occur: twitching first at the angle of the mouth, then by the nose, the eye, and the facial muscles.
Which hormonal disorder may be suspected when positive Chvostek and Trousseau signs are assessed?
Hypoparathyroidism is similarly correlated with hypocalcemia which can cause abdominal pains, muscle cramping, and paresthesias. The 2 clinical tests commonly done to evaluate for hypocalcemia are Chvostek and Trousseau signs.

What is Chvosteks sign?
The increased irritability of the facial nerve, manifested by twitching of the ipsilateral facial muscles on percussion over the branches of the facial nerve, came to be known as Chvostek sign. This clinical finding has become widely accepted in the medical community as a sign of hypocalcemia.
