Trousseau’s sign

Leg and foot cramps, hypertension, tachycardia, neuromuscular irritability, tremor, hyperactive deep tendon reflexes, confusion, disorientation, visual or auditory hallucinations, painful paresthesias, positive Trousseau s sign, positive Chvostek s sign, convulsions Hypermagnesemia... 

Trousseau s sign An indication of latent tetany in which carpal spasm occurs when the upper arm is compressed, as by a tourniquet or a blood pressure cuff. 

Neurologic Chvostek s and/or Trousseau s signs can be elicited during physical examination. The hallmark of acute hypocalcemia is tetany, which is characterized by neuromuscular irritability including seizure potential. Ex-trapyramidal disorders, mainly parkinsonism but also dystonia, hemiballismus, choreoathetosis, and oculogyric crises, occur in 5% to 10% of patients with idiopathic hypoparathyroidism. 

Neuromuscular Presence of Chvostek s sign. Trousseau s sign (see description below), tremor, and tetany. 

Trousseau s sign—A hand spasm produced by placing a blood pressure cuff over the forearm and inflating the pressure above the systolic pressure for 3 minutes. 

Neuromuscular excitability and tetany Chvostek s and Trousseau s signs... 

A tourniquet applied to the upper arm induces carpopedal spasm due to contraction of the flexors of the arm and wrist, the extensors of the phalanges, and the abductor of the thumb. These combinations of muscle contractions lead to a position of the hand referred to as Trousseau s sign. The application of a mild galvanic current (below 6 milliamps) to the motor nerves leads to contraction of the muscles controlled by these nerves (Erb s sign). 

RED FLAG Keep caldum. gluconate on hand for a patient with a positive Trousseau s or Chvostek s sign. Hypocalcemia may progress quickly to tetany, seizures, respiratory arrest, and death.
