护理人员对机械通气患者气道内滴注生理盐水湿化认知的调查

目的了解护理人员对机械通气患者气道内滴注生理盐水湿化的认知状况，为临床护理干预提供理论依据。方法采用自行设计的气道湿化认知问卷，对北京市6所三级甲等综合性医院的152名临床护理人员进行问卷调查。结果护理人员对气道内滴注生理盐水湿化相关知识的认知程度相对较低，仅27．63％的护理人员了解痰液黏稠度的分级情况；护理人员对机械通气患者气道内滴注生理盐水湿化的认同率相对较高，77．63％的护理人员支持气道内滴注生理盐水湿化；不同年龄、工作年限的护理人员对湿化液的合适用量、痰液黏稠度分级认知情况差异有统计学意义（x^2=33．33，8．55；P〈0．05）；对于是否根据医嘱执行操作、是否将操作内容写入护理记录、是否有相应的操作标准，不同文化程度、职称的护理人员间差异有统计学意义（P〈0．05）。结论护理人员对机械通气患者气道内滴注生理盐水湿化操作的认同率较高，对人工气道湿化方面的相关知识欠缺，自我保护意识亟待加强。

Investigation on the cognition of nursing staff on mechanical ventilation in patients with normal saline drip airway humidity

Objective To understand the cognitive status of nursing staff on mechanical ventilation in patients with normal saline drip airway humidity,so as to provide theoretical basis and reference for related studies.Methods 152 nursing staff from 6 class-A grade three comprehensive hospitals in Beijing were investigated by a self-designed questionnaire,using convenience sampling method.Results The cognitive degree of the nursing staff on the knowledge of normal saline drip airway humidity was relatively low; only 27.63％ nurses know the classification of cases of sputum viscosity.The approval rating of the operation of normal saline drip airway humidity was relativdy high and 77.63％ staff understand the normal saline drip airway humidity; the cognition of the nursing staff with different age,education,work experience and professional title has significant differences (x2 =33.33,8.55 ;P ＜ 0.05).Whether base the doctor's orders to perform operations,whether the operation was written into the contents of nursing records,whether have appropriate operating standards,education level and title were different between the two groups (P ＜ 0.05 ).Conclusions The approval rating of the operation of normal saline drip airway humidity was relatively high among nursing staff,but relevant knowledge of airway humidity was lack; relevant standards of airway management is insufficient; self-protection awareness of the nursing staff should be strengthened.
