鼻塞联合高氧液给氧预防高龄患者硬膜外麻醉低氧血症的研究

目的探讨鼻塞联合高氧液预防高龄患者硬膜外麻醉低氧血症的疗效。方法60例硬膜外麻醉的高龄患者,随机分为两组,每组30例。实验组为鼻塞联合高氧液给氧;对照组为单纯鼻塞给氧。观察两组患者麻醉前后不同时点PaO2、SpO2的变化。结果麻醉前两组间比较差异无显著意义;麻醉后各时点两组比较,实验组PaO2,SpO2明显高于对照组(P<0.01/P<0.05)。结论鼻塞联合高氧液给氧技术,能有效预防高龄患者硬膜外麻醉引起低氧血症的发生。

Study for the prevention effect of epidural hypoxemia among aged patents by nasal style combined with high oxygen liquid oxygen

Objective To study the preventive effect of nasal style combined with high oxygen liquid oxygen for aged patients with epidural hypoxemia. Method 60 aged patients with epidural blockade was randomly divided into experimental group and control group. Experimental group was supplied nasal style combined with high oxygen liquid oxygen, The control group was simply supplied nasal style oxygen. The changes of PaO2, SpO2 of the two groups of patients before and after anesthesia was observed in different time points. Result There are no significant differences between the two groups before anesthesia; In the different time points after anesthesia, the arterial blood oxygen partial pressure （PaO2）, blood oxygen saturation （SpO2） in the experimental group is obviously higher than that of in control group （P〈0.01/ P〈0.05）. Conclusion Nnasal style combined with high oxygen liquid oxygen technology can effectively prevent epidural hypoxemia for aged patients, and decrease operative and postoperative adverse reactions.
