Abstract：Objective To observe the clinical effects of the Airtraq laryngoscope in patients of general anesthesia with difficult tracheal intubation.Methods Sixty Mallampatis Ⅲ to Ⅳ patients with difficult tracheal intubation scheduled for elective operation under general anesthesia were randomized allocated into two groups ( n=30 for each), which was the Airtraq group and the Macintosh group.Both of the two groups were adopted slow induction.Patients in each group were o-rally intubated with Airtraq laryngoscope or Macintosh laryngoscopy, respectively.The success rate of the first time, intu-bation time, systolic blood pressure ( SBP) , diastolic blood pressure ( DBP) , heart rate ( HR) before anesthesia induction ( T1 ) , after anesthesia induction ( T2 ) , during intubation ( T3 ) and 3 minutes after intubation ( T4 ) of the two groups were compared.The glottic exposure view and postoperative complications of the two groups were observed.Results The first-time successful intubation rate of Airtraq group was higher than Macintosh group (P<0.05).Intubation time of Airtraq group was significantly shorter than Macintosh group (P<0.05).Compared with Macintosh group,SBP, DBP and HR at T3 and T4 of Airtraq group were lower (P<0.05).Airtraq group had lower rate of postoperative complications than Macin-tosh group(P<0.05).The laryngeal exposure rate of grade I in Airtraq group was higher than that in Macintosh group. Conclusions Airtraq laryngoscopy could effective solve the difficult tracheal intubation quickly, achieve better glottic ex-posure view, with less hemodynamic effects and less intubation injuries on human body.Airtraq laryngoscopy was suitable for patients with difficult tracheal intubation.
