Post-surgical hypoparathyroidism (POSH) is a common complication after total thyroidectomy. This study aims to assess the accuracy of serum and ionized calcium and PTH levels on the first postoperative day (POD-1) to predict postoperative hypocalcemia (PoHC), transient hypoparathyroidism (THPT), and permanent hypoparathyroidism (PtHPT).
Biochemical parameters and clinical variables were retrospectively analyzed in 200 patients. The optimal cut-off points were determined using ROC curve analysis. Results were correlated with analytical and clinical variables and patient outcomes.
PoHC incidence in POD-1 was 46%; THPT and PtHPT were 37 and 9%, respectively. Ionized calcium < 4.43 mg/dL on POD-1 predicted PoHC (AUC = 0.9) better than PTH and serum calcium. PTH < 8.06 pg/mL on POD-1 predicted PtHPT (AUC = 0.797). Multivariate analysis identified PTH < 21.2 pg/mL, ionized calcium < 4.43 mg/dL, and serum calcium < 8.76 mg/dL on POD-1 as significant PoHC risk factors.
Ionized calcium on POD-1 predicts PoHC accurately, while serum PTH indicates higher risk for PtHPT.
术后甲状旁腺功能减退症（POSH）是全甲状腺切除术后常见的并发症。本研究旨在评估术后第1天（POD-1）血清和离子钙及甲状旁腺激素（PTH）水平预测术后低钙血症（PoHC）、暂时性甲状旁腺功能减退症（THPT）和永久性甲状旁腺功能减退症（PtHPT）的准确性。
对200例患者的生化参数和临床变量进行回顾性分析。使用ROC曲线分析确定最佳截断点。结果与分析和临床变量及患者预后相关。
POD-1时PoHC的发生率为46%；THPT和PtHPT的发生率分别为37%和9%。POD-1时离子钙<4.43mg/dL预测PoHC（AUC=0.9）优于PTH和血清钙。POD-1时PTH<8.06pg/mL预测PtHPT（AUC=0.797）。多因素分析确定POD-1时PTH<21.2pg/mL、离子钙<4.43mg/dL和血清钙<8.76mg/dL是PoHC的重要危险因素。
POD-1时的离子钙能准确预测PoHC，而血清PTH提示PtHPT的风险较高。
