title: [The application value of parathyroid hormone level in predicting post-operative hypocalcemia after total thyroidectomy].
abstract: OBJECTIVE
  To investigate the application value of parathyroid hormone (PTH) within 24 hours in predicting post-operative hypocalcemia after total thyroidectomy.
  
  
  METHODS
  In this study, we selected 207 consecutive patients, performed total thyroidectomy in our hospital, measured the serum PTH and electrolyte, divided them into subgroups according to the definition of post-operative hypocalcemia, and made the ROC curves analysis combining with clinical data.
  
  
  RESULTS
  The mean value of pre-operative PTHs between groups. show no significant difference (P > 0.05); in the first day after surgery, the post-operative hypocalcemia group have a significant lower average PTHs (P < 0.01). ROC area under the curve (AUC) of day-1 is 0.886, with the PTH cutoff value 16. 8 pg/ml.
  
  
  CONCLUSIONS
  The PTH within 24 hours is an important indicator to judging post-operative hypocalcermia after total thyroidectomy.
