Objective:In thyroid surgery,evaluating the combination of near-infrared auto-fluorescence imaging(NIRAF)with injection of mitoxantrone hydrochloride(MHI)as a tracer to en-hance the identification rate of parathyroid glands,thereby reducing the occurrence of post-thyroidectomy hypocalcemia and parathyroid dysfunction.Methods:A prospective study was conducted from October 2022 to March 2023 at Yidu Central Hospital in Weifang City,involving 80 patients undergoing thyroid surgery.Patients were randomly divided into a combined group and a control group based on their admission time,with 40 patients in each group.In the combined group,0.6 mL of mitoxantrone hydrochloride(MHI)was injected into the thyroid gland during sur-gery,and near-infrared autofluorescence(NIRAF)was used for parathyroid gland identification.The control group only used NIRAF during surgery.Compared the preoperative levels of serum calcium and parathyroid hormone(PTH)between the two groups,as well as the intraoperative accuracy of parathyroid gland identification and the rate of autotransplantation.Postoperatively,the study ana-lyzed PTH levels,blood calcium levels,the rate of inadvertent parathyroidectomy,and the inci-dence of hypocalcemia symptoms.Results:In the combined group,there were 4 cases(10.0％)of parathyroid transplantation,compared to 12 cases(30.0％)in the control group,with a statisti-cally significant difference between the two groups(x2=3.828,P=0.049).The accuracy of parathy-roid gland identification in the combined group was higher than that in the control group(x2=3.899,P=0.048).Additionally,there were 2 cases(5.0％)of inadvertent parathyroidectomy in the com-bined group compared to 10 cases(25.0％)in the control group,with a statistically significant dif-ference between the two groups(x2=4.804,P=0.028).Postoperatively at day 1,the blood calcium levels were(2.24±0.11)mmol/L in the combined group and(2.16±0.17)mmol/L in the control group,and the PTH levels were(27.18±11.77)ng/L in the combined group and(18.57±9.55)ng/L in the control group,with statistically significant differences(P＜0.05)observed in both parameters.At day 3 postoperatively,the blood calcium levels were(2.32±0.17)mmol/L in the combined group and(2.23±0.12)mmol/L in the control group;the PTH levels were(33.03±7.88)ng/L in the com-bined group and(24.89±9.29)ng/L in the control group,with statistically significant differences(P＜0.05)observed in both parameters.After surgery,3 cases(7.5％)of numbness in the extremities or around the mouth were observed in the combined group compared to 10 cases(25.0％)in the con-trol group,with a statistically significant difference(P=0.034).Conclusion:The use of NIRAF combined with MHI can effectively improve the accuracy of parathyroid gland identification during thyroid surgery,thereby avoiding inadvertent removal,reducing the occurrence of postoperative hypocalcemia and parathyroid dysfunction,lowering the incidence of postoperative numbness in the extremities or around the mouth,and enhancing the overall patient experience.
