Abstract

Objective: the aim of this work was to describe characteristics of patients with severe or symptomatic hypocalcemia after total thyroidectomy who required treatment with parenteral calcium.
Methods: the authors conducted an observational retrospective analysis at a reference hospital in Medellín, Colombia.
Background: postoperative hypocalcemia is a frequent complication after thyroidectomy; it is characterized by the presence of hypocalcemia with low or normal values of parathyroid hormone. Symptomatic or severe hypocalcemia (serum calcium <7.5 mg/dL) is a medical emergency and require early diagnostic and treatment with parenteral calcium.
Patients: Patients with severe or symptomatic hypocalcemia after total thyroidectomy.
Intervention: treatment with parenteral calcium.
Results: symptomatic or severe hypocalcemia was present in 8 % of patients who went to total thyroidectomy, most of patients were female, and thyroid cancer was main indication for surgery; the average of parathyroid hormone (PTH) value was 11.3 pg/mL and the lowest calcium value was present at 48 hours in the postoperative period. Parathyroid glands only were visualized in one third of these patients and just one patient had second surgery in the first 24 hours; 18% of patients had hypomagnesemia associated with hypocalcemia.
Conclusion: postoperative hypocalcemia due to hypoparathyroidism is a frequent complication after thyroid surgery; some of these patients will develop symptomatic or severe hypocalcemia and require parenteral calcium. It is important identify and treat this condition as an emergency with the propose of diminishing associated morbidity and mortality.
