ABSTRACT
Objective To investigate the effect of nano carbon tracer for protecting parathyroid function in the surgery of thyroid cancer.Methods A total of 178 patients with thyroid cancer admitted in our hospital from Jun.2014 to Mar.2016 were collected and divided into the control group and the observation group according to the random number table method,89 cases in each group.The control group received routine surgery,while the observation group received nanocarbon suspension during surgery.The levels of serum parathyroid hormone and serum calcium in the 2 groups were measured at 3 days after surgery,and the patients with low parathyroid hormone,normal parathyroid hormone and low calcium were counted.Results The rate of ormal serum calcium in the observation group was 91.01％(81/89),significantly higher than 67.42％(60/89) in the control group (P＜ 0.05).The rate of normal parathyroid hormone in observation group was 94.38％ (84/89),significantly higher than 64.04％ (57/89) in the control group (P＜0.05).Conclusion The nano carbon tracer is helpful for protection of parathyroid function in the surgery of thyroid cancer.
ABSTRACT
Objective:to explore the effect of nano-carbon tracer on the dissection of central group lymph nodes in thyroid cancers.Methods:60 patients with thyroid cancers enrolled from January 2015 to December 2015 in our hospital were selected as research objects.Tracing group contained 30 cases would carry out nano-carbon tracer for the dissection of lymph nodes,while the other 30 patients without using nano-carbon tracer were defined as control group.The number of dissected lymph nodes,the discovery rate of positive lymph nodes and the postoperative parathyroid function were made a comparison between the two groups.Results:the total number of dissected lymph nodes in the tracing group was more than the control group (269 vs 204).The average number of dissected lymph nodes in the tracing group (8.97 ± 1.65/case) was also significantly more than the control group(6.8 ± 1.52/case)(P＜0.05).In the tracing group,the total discovery rate of positive lymph nodes was 40.15％,while the control group was 37.25％.Therefore,the average number of dissected positive lymph nodes in the tracing group (3.6 ± 1.16/case) was significantly more than the control group (2.53 ± 1.17/case)(P＜0.05).Observation of the postoperative adverse reactions,there were fewer patients suffering hypocalcemia or recurrent laryngeal nerve injury in the tracing group compared to the control group.In detail,although the blood calcium levels on the 2nd day after operation in both two groups decreased compared with preoperative baseline values,significantly statistical difference was only observed in the control group with 2.173 ±0.20mmol/L in postoperation vs 2.28 ± 0.06mmol/L in pre-operation (P＜0.05).What's more,the blood calcium level in the tracing group on the 2nd day after operation (2.27 ± 0.19mmol/L) was significantly higher than the control group (2.173 ± 0.20mmol/L)(P＜0.05).Besides,the postoperative PTH levels in both two groups reduced in some degree compared to the preoperative baseline values,but there were no statistical differences (P＞0.05).Conclusion:using nano-carbon tracer during the operation would be benefit for the dissection of positive central group lymph nodes,the recognition of parathyroid glands and reduction of postoperative adverse reactions.
