摘 要: | 研究吸痰对组织氧代谢的影响。方法:观察14例危重病人吸痰前,吸痰结束时及吸痰后5min动脉血气和混合静脉血气的变化。结果:与吸痰前相比,吸痰结束时的动脉血氧分压、血氧饱和度,混合静脑海因氧分压,血氧饱和度均显著降低,吸痰结束后5min,SvO3仍未恢复正常。

Effect of Tracheal Suctioning on Tissue Hypoxia in Critically ill Patients |
| |
Abstract: | Objective:To evaluate the effect of tracheal suctioning on tissue oxygenation in critically ill patients. Methods:Fourteen critically ill patients with artificial airway and mechanical ventilation were studied. Data of arterial and mixed venous blood gas were collected at pre suction, end of suction and 5min postsuction. Results:Compared with pre suction,PaO 2, SaO 2,PvO 2 and SvO 2 decreased markedly at the end of suction. 5min post suction, hypoxemia was improved, but SvO 2 remained at low level. Conclusion:Arterial hypoxemia and tissue hypoxia maybe induced by tracheal suction. |
