Clinical Investigation Of Serum Calcium And Parathyroid Function After Thyroid Surgery

To investigate the rule, etiology and treatment of hypocalcemiaand the effection of parathyroid function after thyroid surgery.Clinical data of 2357 cases was analyzed and serum calcium wasobserved and closely followed up.PTH of 17 patients was checked.We found that during the postoperative period, hypocalcemiahappened,13cases in subtotal thyroid lobectomy,14cases in totalthyroidectory,304 cases in unilateral lobectomy with contralateralsubtotal lobectomy,53 cases in unilateral subtotal lobectomy withcontralateral subtotal lobectomy,2 cases in unilateral lobectomy withcontralateral partial thyroid lobectomy.In 17 patients who acceptedthe inspection of PTH, there were 1 case in total thyroidectory,11cases in unilateral lobectomy with contralateral subtotallobectomy,5 cases in unilateral subtotal lobectomy with contralateralsubtotal lobectomy. Especially, 19 cases in preoperation werehypocalcemia.We can make a conclusion : (1) Hypocalcemia andhypoparathyroidism often occur in total thyroidectory and unilaterallobectomy or subtotal lobectomy, with contralateral subtotallobectomy. (2) Great changes should take in serum calcium withinthree days after thyroid surgery.It is the most significant in thesecond day after thyroid surgery. (3) The patient who has acceptedunilateral subtotal lobectomy with contralateral subtotal lobectomyshould be observed the level of serum calcium in three days afterthyroid surgery at least.it is necessary to treat hypocalcemia. (4)There is relationship between hypocalcemia after thyroid surgeryand doctor experience. Professional doctor is superior to one who isnot professional.(5) It is important for the patient who has acceptedthyroid surgery to observe the level of serum calcium in preoperationand postoperation.Some patients have had hypocalcemia orhypoparathyroidism before the thyroid surgery.
