Efficacy of Disposcope endoscope for tracheal intubation in patients with difficult glottis exposure / 中华麻醉学杂志

ABSTRACT

Objective To evaluate the efficacy of Disposcope endoscope for tracheal intubation in patients with difficult glottis exposure.Methods Sixty adult patients of both sexes,aged 22-68 yr,scheduled for elective oro-tracheal intubation under general anesthesia,whose glottis was not visible under Macintosh laryngoscope (grade Ⅲ or according to Cormach-Lehane Grading of laryngoscopic view),were randomized into 2 groups (n =30 each) using a random number tablegroup Macintosh laryngoscope-assisted Disposcope endoscope (group DM) and group Disposcope endoscope (group D).The glottis exposure condition and time,intubation condition and time,assisted lifting mandible,laryngeal mucosa bleeding and postoperative sore throat and hoarseness were recorded.Results The success rate of intubation at second attempt achieved 100％ in the two groups.Compared with group DM,the incidence of assisted lifting mandible was decreased,and no significant changes were found in the success rate of glottis exposure,glottis exposure time,intubation time,success rate of intubation at first attempt,incidence of laryngeal mucosa bleeding,and postoperative sore throat and hoarseness in group D.Conclusion Disposcope endoscope can improve the condition for tracheal intubation significantly after lifting mandible in patients with difficult glottis exposure.
