Tauser's sign positive

Introduction The Trousseau levy, also known as the Taurus sign, can be tied to the forearm by a tourniquet or a blood pressure monitor to a systolic pressure of 20 mmHg for 3 minutes. It can also be used to force the upper arm vein to reduce the blood supply to the wrist. Positive may be alkalosis, hypomagnesemia, hypokalemia or hyperkalemia. All manifestations of hypocalcemia can be masked by the presence of hypokalemia. A tourniquet or a blood pressure monitor can be used to inflate the forearm to 20mmHg above the systolic pressure for 3 minutes. The upper arm vein can also be pressed by hand to reduce the blood supply to the wrist.

Cause

Due to hyperventilation, or the use of NaHCO3 or calcium-diuretic diuretics such as furosemide, further reduction of ionized calcium makes the hidden sputum become apparent. All manifestations of hypocalcemia can be masked by the presence of hypokalemia.

Trousseau can be tied to the forearm with a tourniquet or sphygmomanometer to inflate to 20mmHg above the systolic pressure for 3 minutes, so that the blood supply of the hand is reduced to promote the wrist. The Trousseau sign also occurs in alkalosis, hypomagnesemia, hypokalemia and hyperkalemia, and about 6% of people have no electrolyte disorder. Due to hyperventilation, or the use of NaHCO3 or calcium-diuretic diuretics such as furosemide, further reduction of ionized calcium makes the hidden sputum become apparent. All manifestations of hypocalcemia can be masked by the presence of hypokalemia.

Differential diagnosis

The Chvostek sign and the Trousseau sign are carried out at the bedside to stimulate the latent sputum. The Chvostek sign is a slight deduction of the external nerves of the external auditory canal causing involuntary contraction of the facial muscles. 10% of normal healthy people are present, and chronic hypocalcemia is often lacking.
