AbstractObjective To compare the impacts of different nostril on nasotracheal intubation with video laryngoscopy.Methods Totally 120 ASA grade I maxillofacial surgery patients were equally randomized into two groups:group A(left nostril)and group B(right nostril).After rapid induction of anesthesia,the nasal intubation was completed by Tosight video laryngoscope,and the success rate of the first attempt of the tube passing through the nasal cavity was recorded and compared between these two groups.In addition,time of tube through nasal cavity,time of glottis exposure,total intubation time,intubation success rate,and nasal bleeding were recorded.Results The success rate of the first attempt of tube passing through the nasal cavity was not significantly different between groups A and B(84.7% vs. 81.7%;χ2=0.202,P=0.653).The time of tube passing through nasal cavity [(7.3±4.6)s vs.(7.5±4.1)s;t=-0.223,P=0.824] and the time of glottic exposure [(6.6±1.4)s vs.(6.7±1.4)s;t=-0.348,P=0.728] had no significant differences between two groups.The success rates of first intubation attempt were 100% in both groups.The total intubation time was(35.1±9.2)s in group A and(34.0±7.8)s in group B(t=0.663,P=0.509).Intubation-related epistaxis was found in 16 cases(27.1%)in group A and in 17 cases(28.3%)in group B(χ2 =0.022,P=0.882).Conclusion Different nasal approaches have no effect on nasal intubation.
