摘要
目的 :探讨重型颅脑损伤颈静脉氧饱和度 (SjvO2 )变化及影响因素。方法 :重型颅脑损伤 33例为样本 ,采用右颈静脉穿刺置管 ,持续监测SjvO2 ,并同时监测颅内压 (ICP) ,平均动脉压 (MABP)和脑灌注压(CPP)。结果 :重型颅脑损伤后SjvO2 明显降低。影响SjvO2 的主要因素为ICP、CPP、伤后病理及病情转归。结论 :本研究结果表明 ,持续SjvO2 监测能反映重型颅脑损伤后脑氧代谢的情况 ,可以早期发现脑组织的缺血缺氧 ,SjvO2 的显著持续降低提示预后不良。
Objectives:To probe into the alteration of oxygen saturation of juglar vein (SjivO 2) in severe cerbral trauma and its influential factors.Methods:SjvO 2 of 32 cases with severe cerebral trauma were continuously monitored and determined with planting catheters in righ juglar vein,and intracranial pressure(ICP),mean arterial pressure(MAP) and cerebral perfusion pressure(CPP) were monitored simultancously.Results:SjvO 2 in patients with severe ccrebral trauma obviously decreased,the main influential factrocs of which were ICP,CPP,the alteration of pathology after patients' injury and their conditions.Conclusion: Continuous monitoring and determining SjvO 2 can tell us the conditions of oxygen metabolism after brain is severely damaged,and hypoxia and ischemia of cerebral tissues are found as early as possible,so the obvious and continuous decrease of SjvO 2 indicates a bad outcome.
