脑氧饱和度监测用于颈部大动脉手术围术期管理

目的:探讨颈部大动脉手术围术期脑氧供需平衡的管理.方法:通过对颈部大动脉手术患者(颈动脉体瘤8例、颈动脉狭窄7例)围术期脑氧饱和度(rSO2)、动脉压和颈内动脉反流压等监测,维护患者术中脑氧供需平衡.结果:颈动脉狭窄患者和颈动脉体瘤患者双侧rSO2对照差别具有统计学意义(P<0.05);颈动脉体瘤患者术侧阻断前、中、后rSO2有显著差别(P<0.05);颈动脉狭窄患者阻断动脉开放前后即时rSO2的变化是有差别的(P<0.05);两例患者因术中反流压过低行动脉旁路术.结论:术中rSO2监测对患者围术期脑氧供需平衡的管理具有重要的指导意义.

Application of cerebral oximetry in perioperative management for neck regional main artery surgery

AIM: To investigate the management of perioperative cerebral oxygen balance for neck regional main artery surgery. METHODS: Fifteen patients (eight with carotid artery stenosis, seven with carotid body tumor) were enrolled in the study, whose cerebral oximetry (rSO_2), artery blood pressure(ABP) and carotid reverse blood pressure were continuously monitored and recorded during perioperative period. RESULTS: The rSO_2 monitored from the two sides of the carotid was significantly different (P<(0.05)) and the rSO_2 of the patients with carotid body tumor was significantly different before and after carotid clamping (P<0.05). The transient change of rSO_2 of patients with carotid artery stenosis was different before and after clamping the carotid. Two patients underwent artery bypass operation due to the low reflux pressure of internal carotid artery. CONCLUSION: The monitor of rSO_2 during neck regional main artery surgery helps the management of perioperative cerebral oxygen balance for neck regional main artery surgery.
