Estudo prospectivo da hipocalcemia clínica e laboratorial após cirurgia da tireoide Prospective study of clinical and laboratorial hypocalcemia after thyroid surgery
Abstract
A hipocalcemia pode ser detectada clínica e laboratorialmente após a tireoidectomia. OBJETIVO: Analisar a incidência e fatores de risco da hipocalcemia clínica e laboratorial após cirurgia da glândula tireoide. MÉTODOS: Trata-se de um estudo prospectivo de 91 pacientes submetidos à tireoidectomia. Aspectos demográficos, intraoperatórios e anatomopatológicos foram correlacionados com os achados de hipocalcemia. RESULTADOS: Foram considerados fatores de risco para o hipoparatireoidismo clínico a faixa etária acima dos 50 anos (p = 0,022) e realização de cirurgia não parcial (p Hypocalcemia can be detected clinically and through lab tests after thyroidectomy. AIM: To analyze the incidence and risk factors of clinical and laboratorial hypocalcemia after thyroid surgery. METHODS: Prospective study of 91 patients undergoing thyroidectomy. Demographics, intraoperative, and pathological aspects were correlated to our hypocalcemia findings. RESULTS: Age higher than 50 (p = 0.022) and complete thyroidectomy (p < 0.001) were considered risk factors for hypoparathyroidism. Complete thyroidectomy was considered a risk factor for the 48-hour laboratorial hypoparathyroidism (p = 0.004). There was no risk factor associated with the one-month laboratorial hypoparathyroidism. There was significance between the 48-hour and the one-month laboratorial hypoparathyroidism. CONCLUSIONS: Thyroidectomy extension is a risk factor for both the clinical and laboratorial hypoparathyroidism, whereas age is a risk factor for clinical hypoparathyroidism. The detection of 48-hour laboratorial hypoparathyroidism is a predisposing factor for the one-month laboratorial hypoparathyroidism. However, most of the cases were temporary.
