Postoperative parathyroid hormone (PTH) levels reliably predict hypocalcemia after thyroidectomy. Measuring PTH on the first day helps identify high-risk patients, potentially shortening hospital stays.
Area of Science:
- Endocrinology
- Surgical Oncology
- Neurosurgery
Background:
- Post-thyroidectomy hypocalcemia is a common complication.
- Accurate prediction of hypocalcemia is crucial for patient management and hospital resource optimization.
Purpose of the Study:
- To identify patients at high risk of developing hypocalcemia after thyroidectomy.
- To evaluate the utility of postoperative parathyroid hormone (PTH) levels in predicting hypocalcemia.
Main Methods:
- Prospective study of 160 patients undergoing total thyroidectomy.
- Measurement of pre-operative (PTH1) and first-day post-operative (PTH2) parathyroid hormone levels.
- Daily serum calcium monitoring until discharge; hypocalcemia defined by serum calcium below the normal range.
Main Results:
- 66 patients (41.25%) experienced hypocalcemia, with 57 (35.6%) having transient and 9 (5.6%) persistent cases.
- Postoperative hypocalcemia significantly correlated with PTH2 levels and the percentage drop in PTH (P < .001 and P = .002).
- A PTH2 level of 9.6 pg/mL demonstrated optimal sensitivity and specificity for predicting hypocalcemia.
Conclusions:
- First-day postoperative PTH measurement is a valuable tool for predicting post-thyroidectomy hypocalcemia.
- This method can help avoid prolonged hospitalizations by identifying at-risk patients early.
- Postoperative PTH assay is a reliable and cost-effective alternative to intraoperative testing.
