早期氧气面罩雾化给氧对纠正重型颅脑损伤患者低氧血症的影响效果观察

目的探讨氧气面罩雾化给氧方式对重型颅脑损伤患者低氧血症的可行性及安全性，以促进患者早日康复。方法将收治98例重型颅脑损伤患者随机分为观察组48例和对照组50例，在常规治疗的同时，观察组采用氧气面罩接雾化器给氧方式进行给氧；对照组采用鼻塞导管湿纱布覆盖口鼻进行给氧。结果观察组其动脉血氧饱和度、氧分压明显提高。2组病死率比较差异明显，而2组患者的心率、血压、pH、PaCO2比较差异不明显。结论氧气面罩雾化器给氧能快速、有效纠正重型颅脑损伤患者缺氧状态，纠正低氧血症。

Observation in effect of early oxygen atomizing inhalation with oxygen mask on correction of hypoxemia of patients with severe head injury

Objective To explore the feasibihty and safety of early oxygen atomizing inhalation with oxygen mask on correction of hypoxemia of patients with severe head injury in order to promote the early recovery of patients. Methods 98 cases of patients with severe head injury were randomly divided into the observation group（48 cases） and the control group（50 cases）, the observation group received conventional treatment as welt as oxygen atomizing inhalation with oxygen mask, the control group used nasal catheter with wet gauze covering mouth and nose for oxygen supply. Results The arterial oxygen saturation rate, partial pressure of oxygen markedly improved in the observation group. Significant difference existed in mortality rate between the two groups, while no significant difference was seen in heart rate, blood pressure, pH and PaC02 between the two groups. Conclusions Oxygen atomizing inhalation with oxygen mask can quickly and effectively correct the hypoxic state and correct hypoxemia of patients with severe head injury.
