摘　　要：[目的]观察麻醉苏醒室低氧血症病人不同给氧方式的效果。[方法]将麻醉苏醒室发生低氧血症的60例病人随机分为观察组和对照组各30例,对照组采取双孔鼻导管吸氧,观察组采取非重复式呼吸面罩吸氧。观察两组病人入苏醒室后即刻(T1)、入苏醒室30min(T2)2个时间点的二氧化碳分压(PaCO_2)、氧分压(PaO_2)、pH值、动脉血氧饱和度(SaO_2);调查两组病人对T2时间点的鼻腔干燥不适、吸氧异味、恶心呕吐及胸闷不适的满意度;观察病人在T1、T2时间点平均动脉压(MAP)、心率(HR)、脉搏血氧饱和度(SPO_2)。[结果]两组病人组内吸氧前后PaO_2、SPO_2比较,吸氧后T2时间点PaO_2、SPO_2比较,差异有统计学意义(P<0.05);观察组在T2时间点心率减慢程度显著高于对照组,差异有统计学意义(P<0.05);观察组病人鼻腔干燥不适、吸氧异味满意度高于对照组,差异有统计学意义(P<0.05)。[结论]麻醉苏醒室低氧血症病人采取非重复式呼吸面罩吸氧能有效改善氧分压和生命体征,利于术后康复。Objective：To observe the effect of different oxygen delivery methods in patients with hypoxemia in postanesthesia care unit（PACU）.Methods：Sixty patients with hypoxemia in recovery room were randomly divided into 2 groups：control group（n=30）treated with oxygen inhalation by nasal cannulas,and observation group（n=30）received non-repetitive respiratory mask oxygen inhalation.The levels of arterial carbon dioxide partial pressure（PaCO2）,arterial oxygen partial pressures（PaO2）,pH,and arterial oxygen saturation（SaO2）were observed immediately in PACU（T1）and after 30 minutes（T2）.The satisfaction was observed at T2.The mean arterial pressure（MAP）,heart rate（HR）,pulse oxygen saturation（SpO2）at time points at T1 and T2.Results：There were significant differences in PaO2 and SPO2 levels between two groups before and after oxygen inhalation（P0.05）.There were significant differences in PaO2 and SPO2 levels between two groups after oxygen inhalation at T2（P0.05）.The reduction rate of heart rate was significantly higher in the observation group than in the control group at T2（P0.05）.The satisfaction of nasal dryness and oxygen odor in the observation group was higher than that in the control group（P0.05）.Conclusion：The non-repetitive respiratory mask oxygen inhalation can effectively improve the oxygen partial pressure and vital signs in patients with hypoxemia in PACU,which is beneficial to postoperative rehabilitation.
