To investigate the protective effect of nano-carbon tracking technology on thyroidectomy for adjacent tissues.

A retrospective analysis of 77 patients with thyroid cancer who underwent thyroidectomy from March 2014 to May 2016 was included in the study. Patients were divided into two groups according to whether or not nano-carbon tracking technology was applied. Routine thyroidectomy for conventional group (n=37), patients in the nanocarbon group (n=40) underwent active nano-carbon first and then thyroidectomy. The data of this study were analyzed by SPSS 20.0 software. The surgical related indexes, PTH and serum calcium levels were described by (±s), and compared by independent t test; the parathyroid injury indexes were described by (n, %) and was compared by χ² test; P<0.05 was statistically significant.

There were no significant differences in the operation time, intraoperative blood loss, hospital stay and lymph node metastasis between the two groups (P>0.05), but the number of lymph node clearance in the nanocarbon group was significantly higher than that in the conventional group (P<0.05); Postoperative parathyroid injury in patients of nanocarbon group was significantly less than that in the conventional group (P<0.05); There was no significant difference in serum PTH and serum calcium levels between the two groups before operation(P>0.05). After operation, the serum PTH and serum calcium levels of the patients in the nanocarbon group were higher than those in the conventional group (P<0.05).

The application of nano-carbon technology in thyroidectomy can completely clear the lymph nodes, reduce the occurrence of incidental parathyroidectomy, and reduce the incidence of postoperative hypoparathyroidism, low parathyroid hormone and hypocalcemia.
