Hint : ❣️Low calcium causes tetany and spasms.

Correct Answers:

  • Positive Trousseau's sign


Rationale :

❣️ Hypocalcemia increases neuromuscular excitability, which can produce characteristic signs of tetany such as Trousseau's and Chvostek's signs.

❣️ A positive Trousseau's sign occurs when inflation of a blood pressure cuff causes carpal spasm, including flexion of the wrist and metacarpophalangeal joints.

❣️ Chronic alcoholism can contribute to hypocalcemia through poor nutritional intake, vitamin D deficiency, hypomagnesemia, and impaired calcium metabolism.

❣️ Severe hypocalcemia can also cause muscle cramps, paresthesias, seizures, laryngospasm, and prolonged QT intervals, making prompt recognition important.

❣️ The presence of Trousseau's sign therefore strongly supports significant calcium deficiency and increased neuromuscular irritability.
