HPHJ-A视频喉镜临床应用价值的初步评估

Clinical value of HPHJ-A video laryngoscope:a preliminary assessment

目的初步评估HPHJ-A视频喉镜的临床应用价值。方法 60例需进行气管插管全身麻醉的患者使用HPHJ-A视频喉镜进行插管操作,由两位操作者分别进行30例插管操作,观察并记录患者使用两种喉镜暴露声门的Cormack-Lehane分级、插管所需的操作时间、插管的尝试次数、插管所致各种损伤包括口咽黏膜损伤和(或)牙齿损伤等。结果应用HPHJ-A视频喉镜暴露,13例患者声门Cormack-Lehane分级由Ⅱ级提升为Ⅰ级,7例患者由Ⅲ级提升为Ⅱ级,2例患者由Ⅳ级提升为Ⅱ级,1例患者由Ⅳ级提升为Ⅲ级;26例声门Macintosh喉镜下Cormack-Lehane分级≥Ⅱ级的患者有23例声门可视状况有提升。60例患者中,53例患者一次插管成功,7例患者在第2次尝试中成功。所有患者均无任何重大不良事件,也没有发生黏膜损伤和牙齿损伤。结论 HPHJ-A视频喉镜相比Macintosh喉镜可以提供更好的声门视界,学习操作更容易,可有效改善插管条件,有利于辅助临床麻醉插管。

Objective To preliminarily assess the clinical value of HPHJ-A video laryngoscope. Methods Sixty patients who were to undergo general anesthesia with endotracheal intubation were managed with HPHJ-A video laryngoscope. Two investigators each performed 30 intubations, and the following data were observed and recorded： the Cormack-Lehane grades for exposure of glottis, intubation time, intubation attempts, and intubation-caused injuries such as oropharyngeal mucosa injuries and （or） the teeth injury by two laryngoscopes. Results HPHJ-A video laryngoscope improved the view of the larynx in 23 patients, i.e. 13 patients from grade Ⅱ to grade Ⅰ, 7 from grade Ⅲ to grade Ⅱ, one from grade Ⅳ to grade Ⅲ, and two from grade Ⅳ to grade Ⅱ. HPHJ-A video laryngoscope improved the view of the larynx in 23 of the 26 cases who underwent a standard Macintosh blade. Fifty-three patients were successfully intubated at the first attempt and 7 patients at the second attempts. No patients had noticeable adverse events or mucosal and（or） tooth damage. Conclusion Compared with the Macintosh laryngoscope, HPHJ-A video laryngoscope provides a better glottic view, and it is easier to perform, greatly improving the intubation condition and benefiting the clinical anesthesia with endotracheal intubation.
