A PTH Value at 6 Hours Postsurgery Predicts the Diagnosis of Transient and Permanent Hypoparathyroidism
Authors' conclusion
Measuring PTH levels at 6 hours postthyroidectomy is an accurate method for predicting which patients are at risk of developing transient and/or permanent hypoparathyroidism.
Study context
- Population
- Patients undergoing total thyroidectomy, public tertiary care hospital (Jaén, Spain), September 2021–November 2023
- Participants
- 105 patients
- Exposure
- PTH at 6 hours postsurgery vs corrected calcium at 24 and 48 hours for predicting hypoparathyroidism
- Outcome
- PTH levels 6 hours postoperatively; corrected calcium (adjusted for total protein) at 24 and 48 hours postsurgery
- Follow-up
- 6 hours postoperatively
