Abstract:
Objective To compare the efficacy of Discoscope endoscope and GlideScope video laryngoscope for difficult glottis exposure.Methods Forty adult patients of both sexes scheduled for elective surgery under general anesthesia whose glottis was not visible at laryngoscopy (grade Ⅲ or Ⅳ according to Cormach-Lehane Grading of laryngoscopic view) were randomized into 2 groups (n =20 each):group GlideScope video laryngoscope (group G) and group Discoscope endoscope (group D).The glottis exposure time,intubating conditions,time from exposure of glottis to completion of tracheal intubation and incidence of postoperative sore throat and throat bleeding were recorded and compared between the 2 groups.Results Compared with group G,the glottis exposure time was significantly longer,the rate of backward pressure of cricoid cartilage lower,the time from exposure of glottis to completion of tracheal intubation shorter and the success rate of tracheal intubation at first attempt higher (P ＜ 0.05).There was no significant difference in the success rate of tracheal intubation at second attempt and postoperative incidence of sore throat and throat bleeding between the 2 groups(P ＞ 0.05).Conclusion DiscoScope endoscope is superior to GlideScope video laryngoscope in the management of difficult intubation in term of glottis exposure and success rate of tracheal intubation at first attempt.
