Abstract
Hypocalcaemia from hypoparathyroidism is a wellrecognized
complication of thyroidectomy. It might be
permanent in up to 10%, and temporary in up to 50%, of
patients. It can take up to four days to reach its nadir, and
can lengthen a patient’s hospital stay considerably.
There are three hormones that are primarily concerned
with the regulation of calcium metabolism. Parathyroid
hormone (PTH) 1, 25 dihydrocholecalciferol (Vit.D), and
calcitonin. All the three hormones probably operate in
concert to maintain the constancy of the calcium level in the
body fluids.
This study was done to assess the incidence of
hypocalcemia after different form of thyroid surgery
through measuring total serum calcium, ionize serum
calcium and PTH after thyroid surgery and compare with
their level before surgery.
This study included thirty patients underwent
different forms of thyroidectomy for simple nodular goiter. They were allocated into three equal groups of ten
patients each. In group one total thyroidectomy was done. In
group two near total thyroidectomy was done and in group
three subtotal thyroidectomy was done. Preservation of
parathyroid glands and their blood supply was attempted in
all cases.
Pre-operative PTH and serum calcium were estimated for
the three groups, postoperative serum calcium was estimated
on day one and day six postoperatively, the PTH was
estimated six-hours postoperative in the three groups.
The postoperative serum calcium and PTH were reduced
on day one after all types of thyroidectomy but they were
much apparent after total and near total
thyroidectomy than after subtotal thyroidectomy,
although they were within normal range.
The early detection of post thyroidectomy
hypocalcemia through measuring serum calcium in day one
and PTH six hours postoperative is important to decrease
the post thyroidectomy morbidity and mortality.
