A safe and effective protocol for management of post-thyroidectomy hypocalcemia.

BACKGROUND: This study evaluates the outcomes of a protocol to manage hypocalcemia after thyroidectomy (TTX). METHODS: A review of prospectively collected data was performed in 130 patients who underwent TTX after the introduction of a specific protocol. These patients were compared with a control group of 195 patients who underwent TTX the year prior when routine calcium supplementation was utilized and no specific protocol was used. RESULTS: Of the 120 patients in whom the protocol was followed, 44 (37%) patients were classified as high risk, 15 (13%) intermediate risk, and 61 (51%) low risk. The protocol had a sensitivity of 85% and a negative predictive value of 92% for predicting subsequent hypocalcemia. With the implementation of the protocol, there was significant reduction in temporary hypocalcemia events (P = .008) and intravenous calcium drip (P = .49). Also, calcium supplementation was significantly lower in the protocol group (P ≤ .001). CONCLUSIONS: This hypocalcemia protocol identifies patients who do not require additional supplementation and additional monitoring. At the same time, it identifies those who will benefit from supplementation after TTX
