The aim of the study was to evaluate the efficacy of parathyroid hormone 1-hour assay for the early prediction of hypoparathyroidism after thyroidectomy. Candidates for total, subtotal, completion thyroidectomy or lobectomy were entered into the study. Pre- and postoperative calcium and parathyroid hormone (1 hour and postoperative day 1 after thyroidectomy) levels and clinical hypocalcaemia were recorded. Patients were divided into 3 groups and 2 subgroups: 1. patients who underwent lobectomy (control group); 2. patients who underwent total thyroidectomy with postoperative hypocalcaemia (2A: asymptomatic patients, 2B: symptomatic patients); 3. asymptomatic patients with normal calcium levels after total thyroidectomy. Of 119 patients, 109 underwent total thyroidectomy and 10 lobectomy. Of the 109 patients submitted to total thyroidectomy, 35 (32.11%) developed postoperative transient hypocalcaemia. Twenty-one patients (19.27%) were asymptomatic and 14 (12.84%) were symptomatic. Parathyroid hormone levels decreased after 1 hour in group 3 (32.98 pg/dl), 2A (9.84 pg/dl) and 2B (7.46 pg/dl). There was no significant difference in parathyroid hormone levels at 1 hour between group 2A and 2B (p = 0.06), but were significantly lower compared to groups 3 and 1 (p < 0.05). Parathyroid hormone levels at 1 hour after total thyroidectomy is a good predictor of early hypocalcaemia. It might be more useful than serum calcium monitoring for the early identification of patients requiring postoperative calcium supplementation.

Abstract

The aim of the study was to evaluate the efficacy of parathyroid hormone 1-hour assay for the early prediction of hypoparathyroidism after thyroidectomy. Candidates for total, subtotal, completion thyroidectomy or lobectomy were entered into the study. Pre- and postoperative calcium and parathyroid hormone (1 hour and postoperative day 1 after thyroidectomy) levels and clinical hypocalcaemia were recorded. Patients were divided into 3 groups and 2 subgroups: 1. patients who underwent lobectomy (control group); 2. patients who underwent total thyroidectomy with postoperative hypocalcaemia (2A: asymptomatic patients, 2B: symptomatic patients); 3. asymptomatic patients with normal calcium levels after total thyroidectomy. Of 119 patients, 109 underwent total thyroidectomy and 10 lobectomy. Of the 109 patients submitted to total thyroidectomy, 35 (32.11%) developed postoperative transient hypocalcaemia. Twenty-one patients (19.27%) were asymptomatic and 14 (12.84%) were symptomatic. Parathyroid hormone levels decreased after 1 hour in group 3 (32.98 pg/dl), 2A (9.84 pg/dl) and 2B (7.46 pg/dl). There was no significant difference in parathyroid hormone levels at 1 hour between group 2A and 2B (p = 0.06), but were significantly lower compared to groups 3 and 1 (p < 0.05). Parathyroid hormone levels at 1 hour after total thyroidectomy is a good predictor of early hypocalcaemia. It might be more useful than serum calcium monitoring for the early identification of patients requiring postoperative calcium supplementation.
