目的探讨气切式医用雾化器应用于重型颅脑损伤气管切开患者的临床应用效果。方法选择2009年1月—2011年6月80例重型颅脑损伤行气管切开术的患者随机分为观察组和对照组,每组40例。观察组应用气切式医用雾化器,对照组采用传统方法在气管切开处覆盖双层生理盐水纱布并辅以雾化吸入、气管滴药,比较两组血气分析及气道湿化情况。结果 SPO2<90%观察组0例,对照组12例,占30.0%两组比较差异有统计学意义(P<0.05)。观察组痰液粘稠度Ⅰ、Ⅱ、Ⅲ度者分别占7.5%、87.5%、5.0%均小于对照组,差异均有统计学意义(均P<0.05)。结论重型颅脑损伤患者在气管切开术后使用气切式医用雾化器,能有效湿化气道,有利于痰液的咳出,减少吸痰次数,提高氧疗效果,降低肺部感染率。
Objective To investigate the clinical effect of gas-jet medical nebulizer in tracheotomy patients with severe traumatic brain injury. Methods From January 2009 to June 2011, 80 patients with severe traumatic brain injury underwent tracheotomy were randomly divided into observation group and control group, 40 cases in each group. In the observation group, the gas-cutting medical nebulizer was used in the control group. The control group was covered with double-layer saline gauze by tracheotomy with atomization inhalation and tracheal drip. The blood gas analysis and airway humidification were compared between the two groups. Results There were 0 cases in SPO2 <90% observation group and 12 cases in control group, accounting for 30.0%. There was significant difference between two groups (P <0.05). The sputum viscosities in observation group were 7.5%, 87.5% and 5.0% respectively, which were significantly lower than those in control group (all P <0.05). Conclusion Severe craniocerebral injury in patients after tracheotomy using air-cutting medical nebulizer can effectively humidify the airway is conducive to the sputum sputum, reduce the number of sputum aspiration, improve oxygen therapy and reduce lung infection rate.
