Abstract Objective This systematic review aimed to establish the evidence behind the use of pre-operative calcium, vitamin D or both calcium and vitamin D to prevent post-operative hypocalcaemia in patients undergoing thyroidectomy. Method This review included prospective clinical trials on adult human patients that were published in English and which studied the effects of pre-operative supplementation with calcium, vitamin D or both calcium and vitamin D on the rate of post-operative hypocalcaemia following total thyroidectomy. Results Seven out of the nine trials included reported statistically significantly reduced rates of post-operative laboratory hypocalcaemia (absolute risk reduction, 13–59 per cent) and symptomatic hypocalcaemia (absolute reduction, 11–40 per cent) following pre-operative supplementation. Conclusion Pre-operative treatment with calcium, vitamin D or both calcium and vitamin D reduces the risk of post-operative hypocalcaemia and should be considered in patients undergoing total thyroidectomy.

After thyroid surgery, protocols based on postoperative parathyroid hormone (PTH) levels may prevent symptoms of hypocalcemia, while avoiding unnecessary prophylactic calcium and/or vitamin D supplementation. We examined the value of an initial management protocol based solely on a single PTH level measured one hour after completion or total thyroidectomy to prevent symptomatic hypocalcemia by conducting a retrospective review of 697 consecutive patients treated from July 2003 to April 2015. The proportion of patients who developed symptomatic hypocalcemia was similar between those treated before (n = 155) and after (n = 542) implementation of this 1-hour PTH protocol (16.8% vs 15.9%; P = 0.786). Those in the 1-hour PTH groups had lower overnight observation rates (97.4% vs 53.7%; P < 0.001) and length of stay (1.98 ± 2.61 vs 0.89 ± 1.87 days; P < 0.001), and required less calcium (3.9% vs 0.8%; P = 0.015) and vitamin D (2.6% vs 0%; P = 0.002) supplementation one year after surgery. Less than 1 per cent of patients discharged on the day of surgery in accordance with the 1-hour PTH guidelines returned to the emergency room for symptomatic hypocalcemia; none experienced significant morbidity. This protocol facilitates early discharge of low-risk patients and results in a similar or improved postoperative course compared with traditional overnight observation.

IntroductionHypocalcaemia remains the most common postoperative complication after total thyroidectomy. The purpose of the study was to evaluate the clinical usefulness of routine preoperative oral calcium and vitamin D supplementation in the prevention of hypocalcaemia after total thyroidectomy.Material and methodsOne hundred fifty-three consecutive patients with nontoxic multinodular goitre were randomly assigned to routinely receive (group B) or not to receive (group A) calcium carbonate (3 g/d) and alfacalcidol (1 µg/d) on the day before surgery and calcium carbonate (1 g/d) and alfacalcidol (1 µg/d) taken once in the morning on the day of operation. Their preoperative 25-hydroxyvitamin D (25-OHD) levels, hypocalcemic symptoms, serum calcium and parathyroid hormone (iPTH) levels were determined 6 and 24 hour postoperatively and 6 weeks after surgery.ResultsSymptomatic hypocalcaemia was observed in 41/153(26.79%) patients. The incidence of symptomatic hypocalcaemia was significantly lower in the supplemented group than in the group not receiving supplementation: 10 of 77 participants (12.99%) versus 31 of 76 patients (40.79%) (p<0.05). The rates of laboratory and severe hypocalcaemia (corrected calcium <2.0 mmol/l) were 67.11% and 28.95% in group A and 50.65% and 9.09% in group B, respectively (p=0.04, p<0.05). There were no significant differences between groups A and B in corrected calcium levels after surgery and postoperative decreases in corrected calcium levels (p=0.06). 112(73.20%) participants had 25-OHD<20 ng/ml. Vitamin D levels did not influence corrected calcium level changes (p=0.98).ConclusionsOral supplementation of calcium and alfacalcidol may help in the prevention of postthyroidectomy hypocalcaemia. Vitamin D deficiency was widespread among operated patients.

OBJECTIVE: The purpose of this study was to evaluate if the measurement of peri-operative parathyroid hormone (PTH) is able to identify patients with increased risk of developing symptoms of hypocalcemia. SUBJECTS AND METHODS: Forty patients who underwent total thyroidectomy were studied prospectively. Ionized serum calcium and PTH were measured after induction of anesthesia, one hour (PTH1) and one day after surgery (PTH24). Patients were evaluated for symptoms of hypocalcemia and treated with calcium and vitamin D supplementation as necessary. RESULTS: Symptomatic hypocalcemia developed in 16 patients. Symptomatic patients had significant lower PTH1 and greater drops in PTH levels. The selection of 12.1 ng/L as PTH1 level cutoff level divided patients with and without symptoms with 93.7% sensitivity and 91.6% specificity. The selection of 73.5% as the cutoff value for PTH decrease resulted in 91.6% sensitivity and 87.5% specificity. CONCLUSION: PTH1 levels and the drop in PTH levels are reliable predictors of developing symptomatic hypocalcemia after total thyroidectomy.

Vitamin D plays a crucial role in calcium metabolism through the parathormone-dependent process. The deficiency of this important nutrient may be associated with hypocalcemia after thyroidectomy. To evaluate the role of vitamin D in predicting hypocalcemia following total thyroidectomy. In this study, sixty-two patients who underwent total thyroidectomy for benign or malignant thyroid disease were included in this prospective study. Preoperative vitamin D serum levels and parathormone (PTH) levels were determined. The association between preoperative vitamin D status and the development of hypocalcemia was investigated. In this study, 62 patients were evaluated. The mean age of the subjects was 47 years. Of the 62 patients studied, of which 9 were male patients (14.5%), and 53 were female (85.5%), the results of our study showed. In both groups with and without vitamin D deficiency, calcium levels decreased significantly (P=0.01). In our study, it was found that there was no significant relationship between postoperative hypocalcemia and vitamin D deficiency. (P=0.441). After reviewing the data and according to Spearman correlation statistical test, no significant relationship was observed between serum parathyroid hormone (PTH) and calcium after thyroidectomy (P=0.340). Vitamin D deficiency is a risk factor of hypocalcemia after total thyroidectomy for benign goiter. Although post thyroidectomy hypocalcemia is multifactorial, vitamin D deficiency, particularly severe form, is significantly associated with the development of biochemical and clinical hypocalcemia. Vitamin D supplementation can prevent this unwanted complication in such patients.
