探讨失血性休克不同时间血清一氧化氮 (NO)含量变化 ,了解 NO与失血性休克发展机制的关系。方法 应用重氮反应法(Griss法 )检测血清 NO含量。结果 失血性休克 5 h血清 NO含量较休克前、休克后 1h、2 h显著增高 (P<0 .0 0 1)。其他各时间血清NO含量无明显差异。结论 血清 NO含量与失血性休克持续时间长短有关 ,NO在失血性休克进一步发展机制中具有一定作用。
To investigate the changes of serum nitric oxide (NO) in hemorrhagic shock at different times and to understand the relationship between NO and the development of hemorrhagic shock. Methods Serum NO levels were measured by Griss method. Results Serum NO levels at 5 h after hemorrhagic shock were significantly higher than those before shock and 1 h and 2 h after shock (P <0.01). Other time serum NO content no significant difference. Conclusion The serum NO level is related to the duration of hemorrhagic shock, and NO plays a role in the further development of hemorrhagic shock.
