Description

The usual postoperative measurement of blood calcium is not required in the absence of certain risk factors. While lobectomy or partial thyroidectomy for benign thyroid illness were low risk procedures, whole thyroidectomy, repeat thyroidectomy, and thyroidectomy plus neck dissection all significantly increased the prevalence of long-term hypocalcemia. During thyroid surgery, the accidental removal of several parathyroid glands greatly raised the risk of developing persistent hypocalcemia.

No patient experienced lifelong hypoparathyroidism. Using a multivariate logistic regression analysis, characteristics such as increased free thyroxine levels, malignancy, and sub sternal extension were found to be predictors of postoperative hypocalcemia. Indicating that other variables besides parathyroid damage, ischemia, or removal are involved in the pathophysiology of post-thyroidectomy hypocalcemia, postoperative decline in parathyroid hormone was not an independent risk factor for hypocalcemia. Risk factors for postthyroidectomy hypocalcemia include elevated free thyroxine levels, sub sternal thyroid illness, and cancer. Their existence should prompt frequent postoperative calcium testing.

One further observation relates to the widespread vitamin D insufficiency in the general population, which is an independent cause of hypocalcemia after thyroid surgery and is sometimes referred to as a pandemic. The progression of various electrolyte concentrations, osmolality, proteins, and albumin was similar. The extent of thyroid resection affected both the severity and length of hypocalcemia after thyroid surgery.

Prophylactic calcium and vitamin D supplements appear to be the best course of action up to this point for treating hypocalcemia post-thyroidectomy, which is a complex issue that is still not fully understood. In 135 thyroidectomy patients and 104 control surgery patients, the levels of serum calcium, sodium, potassium, chloride, magnesium, phosphorus, osmolality, total protein, albumin, and parathyroid hormone were rigorously assessed. Following surgery, both thyroidectomies patients and control individuals experienced a brief and mild hypocalcemia. Additional techniques built around quantifying prognostic indicators are required. Permanent hypoparathyroidism necessitates lifelong medication and raises concerns about acute hypocalcemia episodes that can be fatal.

There are a few things about thyroidectomy that is related to hypocalcemia. Three independent risk factors for postthyroidectomy hypocalcemia are parathyroid autotransplantation, bilateral thyroidectomy, and increased free thyroxine levels. First, since thyroid nodules are highly prevalent and relatively easy to find in the general population, thyroidectomies have increased during the past few decades, making post-operative hypocalcemia less uncommon.

For instance, what is the precise time of the post-operative PTH assay to accurately determine the need for calcium supplementation, if the PTH evaluation is a cost-effective technique for detecting hypocalcemia, and what the precise protocol for calcium is and vitamin D supplements following surgery. Additionally, it's critical to appropriately inform patients who receive an early discharge from the hospital or who are treated as outpatients after surgery about the danger of acute tetany and the significance of ongoing monitoring for chronic hypocalcemia.

Conclusion

In this series, we found that the crucial period for serum calcium monitoring was from 24 to 96 hours following surgery. The remainder of the patient's hospital stay would not require serum calcium replacement if it was not required within the first 72 hours following surgery. In addition, we discovered that serum magnesium levels in the postoperative phase should be checked and raised if low. It is unclear what causes transient hypocalcemia after thyroid surgery. An effort was made to keep all parathyroid glands with a healthy blood supply in 18 individuals who had Unilateral (UL) and Bilateral Thyroid Lobectomy (BL).
