Improving safety in paediatric thyroidectomy by PTH measurements

Area of Science:

• Endocrinology
• Pediatric Surgery
• Oncology

Background:

• Post-thyroidectomy hypocalcemia is a common complication.
• Predicting and managing hypocalcemia is crucial for patient recovery.
• Current management strategies may lead to prolonged hospital stays and unnecessary testing.

Purpose of the Study:

• To evaluate an algorithm using pre- and post-operative parathyroid hormone (PTH) levels to predict hypocalcemia.
• To assess the safety and efficacy of this strategy in reducing hypocalcemia, hospitalisation length, and calcium sampling.
• To determine its utility in pediatric patients undergoing thyroidectomy.

Main Methods:

• A risk stratification algorithm based on intraoperative and postoperative PTH levels was applied to 66 pediatric patients.
• High-risk patients received calcium and vitamin D1-25 supplementation.
• Low-risk patients were monitored with daily calcium sampling for up to 48 hours post-surgery.
• Outcomes were compared to a historical control group.

Main Results:

• The incidence of hypocalcemia in high-risk patients decreased from 100% to 17% (p < .001).
• Median hospitalisation length reduced from 6 to 3 days (p < .001).
• Overall incidence of hypocalcemia decreased by 58% compared to controls.
• Neck dissection was identified as a significant risk factor for postsurgical hypoparathyroidism (RR: 2.1).

Conclusions:

• Utilizing PTH levels for risk assessment and preemptive therapy is an effective strategy.
• This approach enhances patient safety by reducing hypocalcemia and hospitalisation duration post-thyroidectomy.
• The algorithm proved beneficial in managing pediatric patients, improving outcomes and resource utilization.
