目的观察急性脑梗死患者颈内静脉血氧饱和度(SjVO2),探讨脑氧代谢变化及其对患者病情及预后评估价值。方法将89例急性脑梗死患者通过SjVO2计算动脉颈内静脉含氧量差(AVDO2)和脑摄氧率(OEF)及治疗1个月后比较预后。结果 SjVO2重症组高于非重症组,而OEF低于非重症组,SjVO2≥70%或≤50%预后不良发生率高于SjVO250%~70%,OEF≤30%预后不良发生率高于OEF>30%组,而AVDO2与预后相关分析差异无统计学意义。结论 SjVO2和OEF可以对大脑半球梗死患者颈内氧代谢状况和脑血流状态客观反映,对患者预后评估有参考价值。
Objective To observe the blood oxygen saturation (SjVO2) of the jugular vein in patients with acute cerebral infarction and to investigate the changes of cerebral oxygen metabolism and the evaluation of the disease and prognosis. Methods 89 cases of acute cerebral infarction patients were calculated by SjVO2 arterial internal jugular vein oxygen difference (AVDO2) and cerebral oxygen uptake rate (OEF) and treatment of 1 month after the comparison of prognosis. Results SjVO2 severe group was higher than non-severe group, while OEF was lower than non-severe group. SjVO2≥70% or≤50%, the incidence of adverse prognosis was higher than SjVO250% ~ 70%, OEF≤30% 30% group, while the correlation between AVDO2 and prognosis showed no significant difference. Conclusion SjVO2 and OEF can objectively reflect the status of intracranial oxygen metabolism and cerebral blood flow in patients with cerebral hemispheric infarction, which may be of reference value for prognosis evaluation.
