甲状腺癌颈丛麻醉与芬太尼微量泵应用的研究

The study on fentanyl microsyringe applied at neck regional plexus anesthesia

目的 观察芬太尼利用微量泵在颈丛神经麻醉下对手术中病人循环功能的调节作用。方法 选择甲状腺癌病人30例,行单侧甲状腺腺叶切除术,采用颈丛神经阻滞麻醉。随机分两组,对照组输入生理盐水,实验组利用微量泵输注芬太尼,观察两组术中血压、心率的变化。结果 实验组术中应激反应小,血压、心率基本保持在术前水平,而对照组则出现血压升高并心率加快。结论 微量泵输注方法的选择既能减轻心血管反应又能保持无呼吸抑制,避免了芬太尼的副反应,是一种值得推广的麻醉方法。

Abstract Objective To study the fentanyl infused with microsyringe restrain the stress of neck regional plexus anesthesia. Methods Select the patients of thyroid adenocarcinoma with neck regional plexus anesthesia. Divide them into 2 groups at random. The test group (group 1) infused fentanyl with microsyringe; the control group(group 2) infused normal saline with microsyringe. Observe the patients' blood pressure(BP) and heart rate (HR). Results The stress of group 1 was small. BP and HR changed little during the operation, group's 2 BP and HR rised. Conclusion Fentanyl infused with microsyringe can restrain the cardiovascular response of neck regional plexus anesthesia.
