Benign Thyroid

Background: Thyroid surgery are among the most common operations performed all over the world. Hypocalcemia following total thyroidectomy is a fairly common complication. Occurrence of acute hypocalcemia can be predicted in patients undergoing thyroid surgery, based on serial calcium measurement and this helps in early prediction of hypocalcemia. The aim of present study was to assess the incidence of post thyroidectomy hypocalcemia and factors which might play a role in its occurrence.Methods: A total 30 patients who underwent bilateral thyroidectomy were analysed. The study period was from June 2017 to March 2019. The incidence of hypocalcemia was analysed with serial calcium estimation in immediate post-operative period, 4 hours and 24 hours after surgery and on 5th post-operative day. The factors analysed included pre-operative and post-operative serum calcium levels, clinical features, the disease type and factors related to surgery. The ethical approval was taken from the ethical committee of the institute. At the end of the study data was collected and analysed by using student t-test and chi square test. A p-value of less than 0.05 was considered significant.Results: Post-operative transient hypocalcemia developed in 21 patients out of 30 (70%). Of them six patients (28.75%) developed severe hypocalcemia and 15 (71.42%) developed mild to moderate hypocalcemia. Out of six patients, five patients were histopathologically diagnosed as malignant thyroid disease. 15 patients who developed mild to moderate hypocalcemia were diagnosed to be having benign thyroid conditions.Conclusions: Patients underwent thyroid surgery for malignant conditions showed higher incidence and severity hypocalcemia as compared to cases where surgery was performed for benign thyroid disease. This complication can be prevented with meticulous perioperative dissection, prompt identification of parathyroid glands and frequent postoperative monitoring of serum calcium levels.

Calcium Measurement

The development and assessment of methods for measurement of total, ultrafilterable and ionised serum calcium is given. An existing fluorimetric technique for total calcium has been automated and modified for routine use. A device for rapidly preparing serum ultrafiltrates has been developed and an electrometric method for ionised calcium measurement assessed. Values in normal subjects are given for all three fractions and compared with the findings of other workers.

Background: Hypocalcemia after thyroidectomy is the most common metabolic complication that prolongs the hospital stay. The aim of this study was to determine timing of hypocalcemia postoperatively and determine the safest day to discharge post-total or near-total thyroidectomy patients based on serum calcium level.Methods: From October 2012 to January 2017, the medical records of 117 consecutive patients who underwent a total or near-total, completion or redo thyroidectomy for benign and malignant thyroid diseases in two university hospitals were prospectively analyzed. The serum calcium was measured preoperatively, on the morning on the first, second, third and fourth postoperative days and the postoperative day on which hypocalcemia developed was identified.Results: Of the 117 patients who underwent a total or near thyroidectomy, 36 (30.7%) developed hypocalcemia, which was transient in 34 (29%) and permanent in two (1.7%) patients. The postoperative hypocalcemia was mild in 10 (8.5%) patients, and 26 (22.2%) patients developed significant postoperative hypocalcemia. Of the 36 patients who developed hypocalcemia postoperatively, the peak incidence of hypocalcemia (72.2%) was on the first postoperative day, and by the third day serum calcium measurement detected 97.3% of patients who developed hypocalcemia.Conclusions: Postoperative serial serum calcium levels may be useful for identifying patients suitable for early discharge following total/near total thyroid surgery in hospitals that lack the facilities. Hypocalcemia peaked on the first postoperative day. However, based on serum calcium levels alone, the third postoperative day is the crucial day for deciding whether to discharge the patients.

Background: Hypocalcaemia following total thyroidectomy is a fairly common complication. Occurrence of acute hypocalcaemia can be predicted in patients undergoing thyroid surgery for malignancy, based on serial calcium measurement and this helps in early prediction of hypocalcaemia. The aim of the study was to assess the incidence of post thyroidectomy hypocalcaemia and methods to treat hypocalcaemia and prevention of its complication at the earliest.Methods: The incidence of hypocalcemia was analysed with serial calcium estimation in immediate post-operative period, 4 hours and 24 hours after surgery and on 5th post-operative day. The factors analysed included pre-operative and post-operative serum calcium levels, clinical features, the disease type and factors related to surgery and histopathologically diagnosis as malignant papillary thyroid carcinoma is confirmed.Results: In this study 30 patients underwent total thyroidectomy for papillary carcinoma were studied. Incidence of 22% of hypocalcemia, with transient hypocalcemia in 20% and permanent hypocalcemia in 2% of cases were noted.  Conclusions: Patients underwent thyroid surgery for malignant conditions showed higher incidence and severity hypocalcaemia. This complication can be prevented with meticulous peroperative dissection, prompt identification of parathyroid gland. Avoiding injury or spasm of the blood vessels supplying them and frequent postoperative monitoring of serum calcium levels.
