ObjectiveTo assess the effectiveness of laryngeal mask airway, endotracheal tube and oropharyngeal airway for airway management in prehospital emergency care.MethodsThe 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.ResultsThe 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).ConclusionLaryngeal mask airway is as effective as oropharyngial airway for pre-hospital airway management by paramedics.
