[The application value of parathyroid hormone level in predicting post-operative hypocalcemia after total
Objective:
To investigate the application value of parathyroid hormone (PTH) within 24 hours in predicting post-operative hypocalcemia after total thyroidectomy.
Method:
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.
Result:
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.
Conclusion:
The PTH within 24 hours is an important indicator to judging post-operative hypocalcermia after total thyroidectomy.
