摘要
目的研究老年人胸段硬膜外麻醉对SpO_2和PETCO_2的影响。方法对48例老年人上腹部手术胸段硬膜外麻醉阻滞过程中SpO_2和PETCO_2进行观察。结果硬膜外注药后SpO_2整个过程各时相与对照值均无显著变化。PETCO_2在硬膜外注药30 min后明显升高,同时动态观察到12例在静推芬氟合剂后PETCO_2升高明显,峰相延长;4例肥胖患者舌后坠明显,PETCO_2有一过性消失;6例患者在30 min后,PETCO_2峰相逐渐低慢,甚至消失,呼吸抑制明显。结论在老年人胸段硬膜外麻醉中监测PETCO_2可及时了解呼吸状态,提高麻醉安全性。
Objective To study the effects of thoracic epidural anesthesia in elderly on 5pO2 and PETCO2. Methods To observe SpO2 and PETCO2 during thoracic epidural anesthesia for abdominal surgery in 48 elderly patients. Results SpO2 in the whole process after epidural injection was of no significant changes. Conclusion PETCO2 monitoring for thoracic epidural anesthesia in elderly can observe timely respiratory status to improve anesthesia safety.
