    Chvostek Chuck — Hypocalcemia

    Twitchy face, tingling lips, watch the airway

    Chvostek Chuck, the MnemoNurse character for Hypocalcemia

    Chuck wakes from thyroid surgery with a buzzing lip and a cheek that jumps when the nurse taps it. His parathyroids took the hit, and now every nerve in his body has its volume turned up.

    Chuck's calcium falls after thyroid surgery, from chronic kidney disease or from massive transfusion. Everything gets irritable: facial twitching (Chvostek's), carpal spasm (Trousseau's), tingling and, at worst, laryngospasm. Keep calcium gluconate and a trach tray nearby.

    The story arc

    1. The setup

      A total thyroidectomy leaves his parathyroid glands bruised and underperforming.

    2. The turn

      He reports tingling around his mouth and in his fingertips overnight.

    3. The crisis

      His cheek twitches when the nurse taps his facial nerve, his hand claws under the cuff, and then his voice turns high and crowing.

    4. The save

      IV calcium gluconate is pushed slowly on a monitor, with a tracheostomy tray at the bedside.
