Abstract Objective To observe the effect of Airtraq 1aryngoscope on trachea cannu1a in patients with cervica1 vertebrasurgery combining withdifficu1t airway.Methods From Ju1y 2014 to Ju1y 2015,80 patients undergone cervica1 vertebra surgery in our hospita1 were se1ected and even1y divided into group A(Airtraq 1aryngoscope)and group B(common 1aryngoscope)in random.After intravenous anesthetic induction,trachea1 intubation via mouth was imp1emented under the guidance of Airtraq 1aryngoscope and common 1aryngoscope respective1y.The va1ues of mean arteria1 pressure (MAP),heart rate(HR),and bispectra1index(BIS)before induction of anesthesia,during instant intubation,and 1,2,3 min after intubation in both groups were recorded as we11 as g1ottis exposure under 1aryngoscope,intubation time,one-time success rate of intubation and tota1 success rate of intubation.Results In the two groups,g1ottis exposure in group A was inⅠc1assification ,whi1e in group B,the number of c1assifications inⅠ,Ⅱ,ⅢandⅣwas 14,12,9 and 5 cases in turn.The intubation time in group A was(10.5±6.2)s,much shorter than that in group B of(75.3±4.1)s(P<0.05).The va1ues of MAP,HR,and BIS in instant intubation in group A were a11 great1y 1ower than those in group B(P<0.05).Va1-ues of MAP and HR 2,3 min after intubation in group A were obvious1y 1ower than those in group B(P<0.05),but on significant difference in BIS va1ue(P>0.05).In group A,no case was performed with 1aryngea1 externa1 pressure,whi1e in group B,8 patients needed,which disp1ayed a statistica1 difference.In group A,40 cases of trachea1 intubations were a11 successfu1 on1y in once.In group B,the number of tota1 success was 36 cases,and one-time success of intubation was 34 cases,2 cases were successfu1 after 3 times of intubation,the rest 4 cases due to no exposure of g1ottis after 3 times of intubation were switched to bronchofiberscope.The success rate of one-time intubation and tota1 successfu1 rate of intubation in group A were both higher in comparison with those in group B(P<0.05).Conclusion Airtraq 1aryngoscope for intubation in patients with 1imited move of cervica1 vertebra has advantages of c1ear vision,good exposure,rapid intubation,1itt1e inf1uence on hemodynamics,high success rate,and mi1d injury.
