A 45-year-old woman on day 1 after total thyroidectomy has perioral and finger tingling, and her hand spasms when the BP cuff inflates. Calcium is 7.2 mg/dL. Breathing is normal and her voice is intact. What is the likely cause and treatment?

1. An anaesthetic allergy treated with an antihistamine only
2. Hypocalcaemia from parathyroid injury, treated with calcium
3. Post-operative anxiety, managed by breathing into a bag
4. A neck haematoma needing the wound opened on the ward now

Answer: B) Hypocalcaemia from parathyroid injury, treated with calcium. Parathyroid injury during surgery causes hypocalcaemia with tingling and Trousseau sign; IV or oral calcium is given by severity.
