Comparison between HPHJ-A video laryngoscope and macintosh laryngoscope in clinical intubation / 第二军医大学学报

ABSTRACT

Objective: To compare the clinical outcomes of intubation between HPHJ-A video laryngoscope and Macintosh laryngoscope, and to analyze the advantages and disadvantages of each approach. Methods: Totally 100 patients who were to undergo general anesthesia with endotracheal intubation were randomly allocated for airway management with one of the two devices HPHJ-A video laryngoscope and Macintosh laryngoscope. The following data were observed and recorded for the two groups the Cormack-Lehane grade of exposing the glottis, hemodynamic alteration before and after endotracheal intubation, intubation time, and intubation attempts. Results: HPHJ-A video laryngoscope resulted in a better glottis exposure than the Macintosh laryngoscope, and the results of hemodynamic alteration, intubation time, and intubation attempts were similar between the two groups. For patients with a difficult airway (Cormack-Lehane III-IV), HPHJ-A video laryngoscope resulted in a slighter hemodynamic alteration(P < 0.05), a higher successful intubation rate, and a shorter intubation time(P < 0.05) compared with Macintosh laryngoscope. Conclusion: The HPHJ-A video laryngoscope can greatly improve the glottic exposure compared with the Macintosh laryngoscope, especially for patients with difficult airway.
