Clinical Application of Shikani Optical Stylet in Guiding Nasal Tracheal Intubation
Objective To explore the clinical application of the Shikani optical style(SOS)in guiding nasal tracheal intubation.Methods A retrospective analysis was made on clinical data of 60 patients who underwent selective operation under general anesthesia through nasal tracheal intubation from January 2017 to December 2022.According to the guidance methods of nasal tracheal intubation,the patients were divided into three groups with 20 cases in each group:video laryngoscope guided nasal tracheal intubation group(group V),fiberoptic bronchoscopy guided nasal tracheal intubation group(group F),and SOS guided nasal tracheal intubation group(group S).The grading of glottis exposure and epistaxis during tracheal intubation were recorded,as well as the success rate,completion time,and incidence of postoperative complications related to nasal tracheal intubation.Results The glottis exposure in the group F and group S were both grade Ⅰ.Among the group V,there were 7 cases of gradeⅠ,10 cases of gradeⅡ,and 3 cases of grade Ⅲ.The glottis exposure effect of patients in the group F and S was significantly better than that of the group V(Z =-4.274,P = 0.000;Z =-4.274,P = 0.000).There were 15 and 14 patients in the group F and the group S without epistaxis,and 5 and 6 patients with mild epistaxis,respectively.There were no patients with severe epistaxis in the group F and the group S.In the group V,there were 7 patients without epistaxis,10 patients with mild epistaxis,and 3 patients with severe epistaxis.The degree of epistaxis in the group F and the group S was significantly less than that in the group V(Z =-2.678,P =0.007;Z =-2.402,P =0.016).The median time for tracheal intubation in the group S was 37.5(34.3,41.5)s,significantly shorter than 45.0(39.8,72.5)s in the group V and 89.0(76.0,102.5)s in the group F(Z =15.703,P =0.013;Z =32.050,P =0.000),with the group V being significantly shorter than the group F(Z =-16.347,P =0.009).The nasal tracheal intubation failed in 2 cases in the group V,while was all successfully completed in the group F and the group S.The difference of success rate was not statistically significant among the three groups(P>0.05).There were no statistically significant differences in the rates of postoperative nasopharyngeal pain and nasal congestion among the three groups(P>0.05).Conclusion The method of SOS-guided nasal tracheal intubation can provide good glottis exposure and achieve a satisfactory success rate of tracheal intubation without increasing the risk of adverse reactions,which can be regarded as a safe and effective method of nasal tracheal intubation.
