Prevention of Hypocalcemia in Patients Undergoing Total Thyroidectomy Plus Central Neck Dissection - Full Text View

Purpose

the increased risk of hypocalcemia following total thyroidectomy plus central neck dissection can be minimized by routine administration of oral calcium and vitamin D supplements during the early postoperative period.

Primary Outcome Measures:

The clinical utility of calcium and vitamin D supplements for prevention of hypocalcemia following total thyroidectomy plus central neck dissection [ Time Frame: To postoperative 12 months ] [ Designated as safety issue: Yes ]

Enrollment:	200
Study Start Date:	May 2004
Study Completion Date:	February 2006
Primary Completion Date:	February 2006 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
No Intervention: C No supplements after total thyroidectomy and central neck dissection
No Intervention: D No central neck dissection group (total thyroidectomy alone)
Active Comparator: A Oral calcium plus vitamin D supplements after total thyroidectomy and central neck dissection	Dietary Supplement: Oral calcium plus vitamin D calcium supplementation took 3 g/day oral calcium (1 g every 8 h) plus 1 mcg/day vitamin D (0.5 mcg every 12 h), beginning on the night of surgery and continuing for 14 days. Other Name: calcium carbonate and one-alpha (vitamin D)
Active Comparator: B Oral calcium alone supplement after total thyroidectomy and central neck dissection	Dietary Supplement: Oral calcium alone calcium carbonate (3 g/day, 1 g every 8 h) Other Name: calcium carbonate (Korea United Pharmaceutical Co, Seoul, Korea)

Detailed Description:

Of patients with differentiated papillary thyroid carcinoma, group D underwent total thyroidectomy alone and groups A-C underwent total thyroidectomy plus CND. The latter were randomized to oral calcium (3 g/day) plus vitamin D (1 mcg/day) (group A, n = 49), calcium alone (group B, n = 49), or no supplements (group C, n = 50). Hypocalcemic symptoms, serum calcium, and parathyroid hormone (PTH) levels were compared among the groups.
