Abstract
Serum PTH 24-h after total thyroidectomy is a reliable predictor of hypocalcaemia and can allow safe early discharge of patients from hospital. Patients with a normal postoperative serum PTH and normal serum calcium the following morning will not develop hypocalcaemia and can be considered for discharge that day. Measuring %iPTH decline, where a decline >72.3% was precise for early diagnosis of hypocalcemia after total thyroidectomy too. Our study didn’t find a difference, between combination of both tests and measuring iPTH24hr only, also did not increase the accuracy. Thus, calculation of the %iPTH decline might not be necessary. Only using a single measurement of iPTH24hr is more convenient and cost-effective in early diagnosis of immediate significant postoperative hypocalcemia.
This is a prospective study to estimate the incidence of hypocalcemia and hypo-parathyroidism following total thyroidectomy for simple multi-nodular goiter (SMNG), and to determine which early clinical and biochemical characteristics could be considered as predictive factors. Also to identify PTH-24 (iPTH-24hr) as a simple predictor of early postoperative hypocalcemia.
