Frecuencia de hipocalcemia pos tiroidectomía total en pacientes de SOLCA, en la ciudad de Cuenca 2000-2016

Abstract

Background: One of the most frequent complications of thyroid surgery is hypocalcemia due to postoperative hypoparathyroidism caused by its devascularization or excision. Symptoms of hypocalcemia range from mild paresthesias, cramps to tetany, convulsions, arrhythmias, and even death.

Objective: To determine the frequency of hypocalcemia after total thyroidectomy in patients from the Cancer Institute SOLCA - Cuenca, in the period 2000-2016.

Methodology: A transverse analytical study with information from 423 clinical records of the SOLCA Institute - Cuenca, period 2000 to 2016, collected in a form, tabulated in the SPSS program, the results of which were presented in tables and graphs analyzed qualitatively (f,%) and quantitative (, DS).

Results: 90.1% of the patients were female, mean age in the group was 48.4 years (SD 15.4). 83 patients had postoperative hypocalcemia, giving an overall prevalence of 41.1%, of which 83.1% was transitory, while the overall prevalence of definitive hypocalcemia was 6.9%.

Conclusions: The majority of thyroidectomized patients were adult women; transient hypocalcemia was high but most normalized calcium values after 6 months of surgery. Hypocalcemia was higher in patients undergoing thyroidectomy and group IV lymph node dissection and in patients with malignant lesions. The presence of clinical symptoms showed an association with laboratory-measured hypocalcaemia and, the paresthesias and the sign of Chevostek were the most frequent clinical signs
