Are preoperative serum calcium, parathyroid hormone, and adenoma weight predictive of postoperative hypocalcemia?

From: The American Surgeon | Date: December 1, 2002| Author: | Copyright information

The objective of this study is to determine whether preoperative serum calcium, parathyroid hormone, or adenoma weight is predictive of postoperative hypocalcemia after removal of a parathyroid adenoma. A retrospective chart review was performed for consecutive parathyroidectomy patients over a 6-year period at a community-based teaching institution. Patients with renal failure (serum creatinine >1.7), hyperplastic disease, and parathyroid carcinoma were excluded. The outcome measures were postoperative serum calcium and the presence of signs or symptoms such as paresthesias, anxiety, or ...
