应用韩氏穴位神经刺激仪(HANS)辅助小剂量颈丛阻滞对甲状腺手术的麻醉

Application of the Han's Acupoint Nerve Stimulator (HANS) Combined with Plexus Cervicalis Blcoking(PCB) in Thyroid Operation

应用ＨＡＮＳ辅助小剂量颈丛阻滞行甲状腺手术麻醉（ Ａ组）、与对照组（Ｂ组） ＨＡＮＳ麻醉各 ４０例。观察麻醉效果及生理功能变化， Ａ组麻醉优良率为 ９３％， Ｂ组 ７５％，两组比较有显著性差异（Ｐ＜０．０５）；Ａ组甲状腺囊腺瘤切除的麻醉优良率为 ９６％，甲状腺次全切除的麻醉优良率为８６％，但两者比较没有差异性（Ｐ＞０．０５）；Ｂ组甲状腺囊腺瘤切除的麻醉优良率为 ８６％，甲状腺次全切除的麻醉优良率为５０％，两者比较有显著性差异（Ｐ＜０．０５）。病人手术前后１５分钟心率（ＨＲ）、平均动脉压（ＭＡＰ）、血氧饱和度（ＳｐＯ_２）的变化，Ａ组ＨＲ、ＳｐＯ_２术后较术前降低，有非常显著性差异（Ｐ＜０．０１），ＭＡＰ降低，有显著性差异（Ｐ＜０．０５）；Ｂ组ＨＲ术后稍升高，但无显著性差异（Ｐ＞０．０５），ＭＡＰ降低，有显著性差异（Ｐ＜０．０５），ＳｐＯ_２降低明显，有非常显著性差异（Ｐ＜０．０１）术后Ａ组与Ｂ组的ＨＲ、ＭＡＰ、ＳｐＯ_２两组间比较，有非常显著性差异（Ｐ＜０．０１）。

In this paper the clinical efficacies of HANS combined with PCB and HANS alone applicated for anesthesia in thyroid operation were observed in 80 cases. They were divided into two groups,group A (40 cases), using HANS and PCB; group B(40 cases), using HANS alone. Results: ①The satisfactory rate of anesthesia of group A was 93%, while group B was 75 %, the difference was significant(P < 0. 05 ). ②The changes of patients' HR, MAP, SpO_2 at 15 minutes before and after operation: In group A, HR, SpO_2 decreased after operation, which were more lower than that of preparation (P < 0. 01 ). MAP was also decreased significantly(p<0. 05). In group B,HR increased somewhat, but the difference was not marked(p >0. 05). MAP decreased, the difference was significant (P< 0. 05). SpoO_a2 decreased was significant (P < 0. 01 ). In group A, HR, MAP and SpO_2 decreased significantly after operation as compared with those in group B(P < 0. 01 ).
