右美托咪定辅助颈丛神经阻滞在甲状腺切除手术麻醉中的应用效果及对生命体征的影响

目的探讨右美托咪定辅助颈丛神经阻滞在甲状腺切除手术麻醉中的应用效果及对生命体征的影响。方法选择我院行甲状腺切除手术的患者94例为研究对象,将其随机分为对照组和观察组,每组47例。对照组采用单纯颈丛神经阻滞麻醉,观察组在对照组基础上给予右美托咪定。比较两组患者的麻醉效果及患者的生命体征。结果对照组T_1、T_2、T_3、T_4的心率和MAP明显高于观察组与T_0时(P<0.05)。观察组患者的麻醉优良率明显高于对照组,嗜睡、术后恶心呕吐及一过性呼吸抑制的发生率均明显低于对照组(P<0.05)。结论右美托咪定辅助颈丛神经阻滞在甲状腺切除术中可增强麻醉效果,减少不良反应。

Application effect of dexmedetomidine-assisted cervical plexus block in anesthesia for thyroidectomy and its effect on vital signs

Objective To investigate the effect of dexmedetomidine-assisted cervical plexus block in anesthesia for thyroidectomy and its effect on vital signs.Methods A total of 94 cases of patients undergoing thyroidectomy in our hospital were selected as study objects and randomly divided into control group and observation group, with 47 cases in each group.The control group was treated with simple cervical plexus block anesthesia, and the observation group was treated with dexmedetomidine on the basis of the control group.The anesthetic effects and vital signs of patients in the two groups were compared.Results The heart rates and MAP at T1, T2, T3 and T4 in the control group were significantly higher than those of the observation group and at T0 (P<0.05).The excellent and good rate of anesthesia in the observation group was significantly higher than that in the control group, the incidences of sleepiness, nausea and vomiting and transient respiratory depression were significantly lower than those in the control group (P<0.05).Conclusion Dexmedetomidine-assisted cervical plexus block in thyroidectomy can enhance the anesthetic effect and reduce adverse reactions.
