Introduction: The incidence of transient hypocalcaemia after thyroidectomy varies in centres. It increases morbidity and delays discharge. This randomised controlled trial aimed to ascertain the usefulness of calcium and Vitamin D supplementation for 1 week pre-operatively in the prevention of hypocalcaemia in patients undergoing total thyroidectomy (TT) for multi-nodular goitre. Methodology: Patients undergoing TT for multi-nodular goitre from January 2019 to August 2019 were included in the study. They were randomly divided into two groups by block randomisation. Group A received oral calcium (500 mg every 6 h) and Vitamin D (calcitriol 0.25 mg every 6 h) 7 days before surgery and Group B did not receive supplementation. Symptoms and signs of hypocalcaemia were monitored. Calcium profile was measured pre-operatively and post-operatively at 6 h, 24 h, 72 h and 14th day. Serum calcium level ≤8.5 mg/dl was considered as hypocalcaemia. Results: 8/62 patients in Group A and 26/62 in Group B had symptoms of hypocalcaemia. 11/62 patients in Group A and 34/62 in Group B developed signs of hypocalcaemia. 15/62 patients in Group A and 36/62 in Group B had biochemical hypocalcaemia. 9/62 patients in Group A and 25/62 in Group B developed post-operative hypocalcaemia, which required post-operative oral supplementation. 3/62 patients in Group A and 16/62 in Group B needed post-operative intravenous calcium supplementation. Conclusions: It is concluded that post-operative hypocalcaemia which manifested as signs and symptoms and correlated with biochemical values was lower after receiving pre-operative oral calcium and Vitamin D3 supplement for 7 days. The need for post-operative supplementation was lower in this group.
