Application of self-made microphone light wand in patients with difficult airway

Objective To study the clinical efficacy of self-made microphone light wand in patients with difficult airway.Methods 42 patients with difficult airway scheduled for tracheal intubation were randomly divided into two groups,21 cases in each group.Self-made microphone light wand was used in group Ⅰ,while laryngoscope was used in group lⅡ.The first successful rate of intubation and the time of intubation were recorded.Hemodynamic change and the complications of intubation were observed in all patients.Results There were no difference in age,sex and weight between two groups (P＞0.05).The first successful rate of intubation in group Ⅰ was significantly higher than that in group Ⅱ (90.5％ vs 57.1％,P＜0.05),the time of intubation decreased significantly in group Ⅰ [(86±19) s vs (276±36) s,P＜0.05].Compared with group lⅡ,the complications of intubation such as hemodynamic change,oropharyngeal mucosal hemorrhage,sore throat and hoarseness in group Ⅰ were better(P＜0.05).Conclusions Self-made microphone light wand is relatively safe,effective and promising in patients with difficult airway.
