颈丛神经阻滞期脑氧饱和度的变化

Changes in Regional Cerebral Oxygen Saturation during Cervical Plexus Block

目的与方法：随机选择３０例ＡＳＡⅠ级的甲状腺腺瘤病人，在双侧颈丛神经阻滞下行甲状腺腺瘤摘除术，术中测定ｒＳＯ２、ＳｐＯ２、ＢＰ、ＨＲ和ＥＣＧ。结果：所有病人术中ｒＳＯ２值均在正常范围内，ＳｐＯ２、ＢＰ、ＨＲ没有明显的改变，且ｒＳＯ２和ＳｐＯ２、ｒＳＯ２与ＢＰ，ｒＳＯ２与ＨＲ没有相关性。结论：颈丛神经阻滞对病人大脑的氧供需平衡影响极小，是一种安全简单有效的麻醉方法。

bjective and Methods:Thyroid adenoma resections were performed under bilateral cervical plexus nerve block in 30 cases.rSO2,SpO2,BP,HR and ECG were monitored prior to cervical plexus block till the end of operation.Results and Conclusion:rSO2 changes were within the normal range in all patients.SpO2,BP and HR was not changed significantly.No correlation among rSO2 and SpO2,rSO2 and BP,rSO2 and HR was found.rSO2 was not changed significantly during cervical plexus block.
