Comparison of HC video-laryngoscope versus Macintosh laryngoscope for tracheal intubation / 中华麻醉学杂志

ABSTRACT

Objective To compare HC video-laryngoscope with Macintosh laryngoscope for tracheal intubation.Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes,aged 18-64 yr,with body mass index 19-27 kg/m2,Mallampati grade Ⅰ-Ⅱ,undergoing elective surgery,were randomly divided into 2 groups (n =30 each)HC video-laryngoscope group (group H) and Macintosh laryngoscope (group M).After induction of anesthesia,the patients underwent orotracheal intubation assisted by HC video-laryngoscope in group H,and by Macintosh laryngoscope in group M.The glottic exposure time,intubation time,Cormack-Lehane grade,the number of pressing the cricoid and intubation-related complications were recorded.Results The rate of satisfactory glottic exposure was significantly higher and the number of pressing the cricoid was smaller in group H than in group M (P ＜ 0.05).There was no significant difference in the glottic exposure time,intubation time and incidence of intubation-related complications between the two groups (P ＞ 0.05).Conclusion The efficacy of tracheal intubation guided by HC video-laryngoscope is better than that guided by Macintosh laryngoscope.
