Abstract: Background
Postoperative hypocalcemia, a common complication after total thyroidectomy is
multifactorial. The management of early hypocalcemia lack uniformity. Universal or
selective supplementation of calcium with or without vitamin D is carried out. The
predictors for postoperative hypocalcemia is widely studied in literature with some
factors described as independent predictors.
Objective
To explore occurrence of post-thyroidectomy hypocalcemia along with analysis
of factors for predicting early and late hypocalcemia. The efficacy of selective
supplementation of calcium with or without vitamin D was studied.
Method
The retrospective analysis of charts of total thyroidectomy patients above 18 years
within a period of four years in a tertiary institute was carried out. The occurrence
of early and late hypocalcemia and their relation with several preoperative and
intraoperative factors were studied. The rates of readmissions for hypocalcemia
symptoms were evaluated. Detailed analysis for relation of 24 hour serum parathyroid
hormone with early and late hypocalcemia was done.
Result
Among 51 patients, 68.62% had early hypocalcemia and 11.76% had late
hypocalcemia. Among other factors, 24 hour intact parathormone level showed
significant relationship with early hypocalcemia with level less than 15 pg/ml
associated with symptomatic status. Out of total patients, 58.8% of patients were
treated for early hypocalcemia. None of the patients not supplemented with calcium
required readmission for early hypocalcemia symptoms.
Conclusion
The symptom based treatment of post thyroidectomy hypocalcemia is shown to
be effective with intact parathyroid hormone at 24 hours having significant role of
predicting symptomatic early hypocalcemia requiring supplementation.
