The protocol had a sensitivity of 85% and a negative predictive value of 92% for predicting subsequent hypocalcemia. The deficiency of parathyroid hormone (PTH) secretion causes postoperative hypocalcemia due to an inhibition of bone resorption, a decrease in the synthesis of 1-25-dihydroxy vitamin D by the kidney and reduced intestinal calcium … DISCUSSION Calcitonin values did not increase after thyroidectomy. A slight correlation was observed between the preoperative serum alkaline phosphatase level and the minimal postoperative serum calcium level. It is concluded that postthyroidectomy hypocalcemia is a multifactorial phenomenon. The Guidelines were compiled by American Thyroid Association ® Guidelines Taskforces selected for their expertise on the topic.

According to age distribution higher incidence of hypocalcemia occurred in patients between 12 to 35 years (table-5,6). Introduction: Hypocalcemia is the most common complication following thyroidectomy in children.

The rate of permanent hypoparathyroidism is 0.4-13.8%. Hypocalcemia Prevention. Hypocalcemia is the most common complication after thyroidectomy surgery and is often the cause of prolonged hospital stay and significant morbidity [8]. Transient hypocalcemia is believed to be caused by transient disruption of the blood supply to the parathyroid glands or removal of one or more glands. 4,9 For example, patients who had their PTH levels measured after surgery and had low levels (< 6-35 pg/mL) 30 minutes to 5 days after total thyroidectomy were prone to development of transient hypocalcemia. If patient remains in mild hypocalcaemic range beyond 72 h post-operatively despite calcium supple-mentation, start alfacalcidol 0.25 micrograms/day (calcitriol may also be used) with close monitoring (see ‘Long-term follow-up’ below) If vitamin D deficiency is the cause, commence vitamin There is a risk of hypocalcaemia following total thyroidectomy and parathyroidectomy surgery, with the nadir being two to five days post operatively.

BAETS recommends that each endocrine / thyroid surgery unit has documented guidelines for the treatment of post thyroid surgery hypocalcaemia and that this document is available to all team members involved in the care of thyroid surgery patients. Your calcium levels can drop below normal as a result of the surgery because the parathyroids regulate calcium levels in your blood. Your doctor should monitor your calcium levels following thyroidectomy. Guidelines to manage post-thyroidectomy hypocalcemia are available for adults, but not children. Transient symptomatic hypocalcemia after total thyroidectomy occurs in approximately 7% to 25% of cases, but permanent hypocalcemia is less common (0.4% to 13.8%). To prevent or manage postoperative symptoms of hypocalcemia after total or completion thyroidectomy, supplementation with calcium, vitamin D, or both should be considered. Given the present evidence, it would appear preferable to diagnose vitamin D deficiency and initiate appropriate cor-rective supplementation prior to surgery (41).
