OBJECTIVE
To assess the effectiveness of laryngeal mask airway, endotracheal tube and oropharyngeal airway for airway management in prehospital emergency care.
METHODS
The study sample of this randomized clinical trial was 54 patients needing pre-hospital airway management. All cases of intubation (ETI); after two failed attempts (37 patients), were randomly assigned to the oropharyngeal airway (OPA), and the laryngeal mask airway (LMA) groups. Patients' hemodynamic, SaO2 and airway management parameters, were compared in three groups. The study data were analyzed by the Chi-square and one-way ANOVA, Bonferroni post-hoc, using SPSS, v. 18.0.
RESULTS
The results demonstrated that before and after the study, there was no significant difference among the study groups in terms of hemodynamic variables (P > 0.05) expect SaO2 (P < 0.001). The results also revealed that in the ETI group (n=17), the number of attempts and the time spent on inserting the airway device was significantly more than other two groups (P < 0.05).
CONCLUSION
Laryngeal mask airway is as effective as oropharyngial airway for pre-hospital airway management by paramedics.
目的
评估喉罩气道、气管内插管和口咽气道在院前急救气道管理中的有效性。
方法
本随机临床试验的研究样本为54例需要院前气道管理的患者。所有插管病例（气管内插管）；在两次尝试失败后（37例患者），被随机分配至口咽气道（OPA）组和喉罩气道（LMA）组。比较三组患者的血流动力学、血氧饱和度（SaO2）和气道管理参数。使用SPSS 18.0软件，通过卡方检验和单因素方差分析、Bonferroni事后检验对研究数据进行分析。
结果
结果表明，研究前后，除SaO2外（P < 0.001），各研究组在血流动力学变量方面无显著差异（P > 0.05）。结果还显示，在气管内插管组（n = 17）中，尝试次数和插入气道装置所花费的时间显著多于其他两组（P < 0.05）。
结论
对于护理人员进行的院前气道管理，喉罩气道与口咽气道同样有效。
