ABSTRACT
Objective:To explore the effect of nano-carbon in lymph node dissection for thyroid cancer.Methods:46 patients with thyriod cancer were randomly divided into treatment group and control group.The identification rate of lymph nodes,lymph node positivity and parathyroid function were compared after surgery.Results:Compare to the control group,the identification rate of lymph nodes in treatment group was higher (P＜0.05),but there was no significant difference on lymph node positivity (P＞0.05).what's more,patients with low blood calcium and parathyroid hormone in treatment group were less than that in control group after surgery (P＜0.05).The difference of severity of clinical symptoms was not statistically significant (P＞0.05).Conclusion:Nano-carbon increases the lymph node identification rate and reduces the risk of parathyriod injury in patients with thyroidectomy.
