Abstract:
Objective To observe the clinical effect of modified laryngeal mask airway combining fiberoptic bronchoscope intubation in difficult airways.Methods Forty patients,21 males and 1 9 females,aged 30-55 years,ASA physical status Ⅰ or Ⅱ,scheduled for elective general anes-thesia surgery after failure to direct laryngoscope two attempts were randomly divided into two groups,20 cases in each group.Patients in group LMA-FOB underwent intubation with modified la-ryngeal mask airway combining fiberoptic bronchoscope,and patients in group FOB underwent intu-bation with fiberoptic bronchoscope.The fiberoptic bronchoscope score,the intubation time and the rate of successful intubation at first attempt were recorded.All the patients were followed up postop-eratively for adverse effects.Results The fiberoptic bronchoscope scores (Ⅰ/Ⅱ/Ⅲ/Ⅳ:1 5/4/1/0 vs. 8/4/5/3,P <0.05)and the rate of once successful intubation (90% vs.60%,P <0.05)was signifi-cantly higher,and the intubation time [(75 ± 20)s vs.(105 ± 25 )s,P < 0.05 ]was significantly shorter in group LMA-FOB than that in group FOB.In group LMA-FOB,one patient had blood stain in the LMA and one patient felt slight sore throat.There were no significant adverse effects in the two groups.Conclusion Modified Laryngeal mask airway combining fiberoptic bronchoscope intubation in difficult airways was effective to improve the grade of the view of the larynn and the success rate of intubation and shorten the intubation time.No significant adverse effect postoperatively was reported. It is relatively safe,effective and promising in patients with difficult airway.
