What is the post-operative care plan for a patient after parathyroidectomy (surgical removal of a parathyroid gland) for endocrinology follow-up?

From the Guidelines

Post-operative care plan for a patient after parathyroidectomy is crucial to prevent complications and ensure a smooth recovery. The patient should be closely monitored for signs of hypocalcemia, hypercalcemia, and other electrolyte imbalances.

Key Components of Post-Operative Care

• Monitoring of ionized calcium levels: Every 4 to 6 hours for the first 48 to 72 hours after surgery, and then twice daily until stable 1
• Calcium supplementation: Calcium gluconate infusion should be initiated if ionized calcium levels fall below normal, at a rate of 1 to 2 mg elemental calcium per kilogram body weight per hour, and adjusted to maintain normal ionized calcium levels 1
• Oral calcium and vitamin D supplementation: Once oral intake is possible, the patient should receive calcium carbonate 1 to 2 g 3 times a day, as well as calcitriol of up to 2g/day, and these therapies should be adjusted as necessary to maintain normal ionized calcium levels 1
• Phosphate management: Phosphate binders may need to be discontinued or reduced, and some patients may require phosphate supplements, depending on serum phosphorus levels 1

Surgical Considerations

• Subtotal or total parathyroidectomy: Both methods can result in satisfactory outcomes, and the choice of procedure may be at the discretion of the surgeons involved 1
• Parathyroid tissue autotransplantation: May be considered, but the risk of recurrence and persistence of hyperparathyroidism should be weighed against the potential benefits 1

Follow-Up and Outcome Measurement

• Regular monitoring of PTH levels: To assess for recurrence or persistence of hyperparathyroidism 1
• Definition of recurrence and persistence: A standard definition should be developed to ensure consistency in future investigations 1

From the Research

Post-Operative Care Plan

The post-operative care plan for a patient after parathyroidectomy for endocrinology follow-up involves monitoring for potential complications and managing symptoms. Some key considerations include:

• Monitoring serum calcium levels to prevent hypocalcemia, which can be a common complication after parathyroidectomy 2
• Managing post-operative hypercalcemia, which can occur in some patients, with 9% of patients presenting with persistence of hypercalcemia and 14% experiencing recurrence 3
• Identifying patients at risk for recurrence of hyperparathyroidism, such as those with higher post-operative calcium or parathyroid hormone levels, or conflicting pre-operative imaging studies 4

Predictors of Recurrence

Several factors have been identified as predictors of recurrence of hyperparathyroidism after parathyroidectomy, including:

• Subtotal parathyroidectomy (STP) 5
• Pre-operative symptoms of calciphylaxis or calcinosis 5
• Elevated pre-operative calcium levels 5
• Elevated post-operative parathyroid hormone (PTH) levels 5, 6
• Age >66.5 years, calcium ≥9.8mg/dL, and PTH ≥80 pg/mL at 6 months post-operatively 4

Management of Post-Operative Complications

The management of post-operative complications, such as hypocalcemia, involves:

• Intravenous (i.v.) calcium supplements 2
• Calcitriol supplementation 2
• Daily follow-up of serum calcium and phosphorus levels to prevent and treat hypocalcemia 2
• Oral and i.v. calcium supplementation and/or active vitamin D metabolites to prevent and treat post-parathyroidectomy hypocalcemia 2
