中文摘要:
      目的 评价LEMON法预测困难气道的临床效果。方法 选择择期行全身麻醉下喉镜暴露气管插管的手术患者1 528例,男680例,女848例,年龄18～83岁,ASA Ⅰ或Ⅱ级。麻醉前进行LEMON法评分,采用受试者工作特征曲线 (receiver operating characteristic curve,ROC)及曲线下面积(area under the curve,AUC)评价LEMON法预测困难气道的临床效果。结果 困难气管插管患者37例,发生率为2.4％。困难喉镜暴露患者106例,发生率为6.9％。LEMON法预测困难喉镜暴露及困难气管插管的AUC分别为0.884(95％CI 0.867～0.899)和0.934(95％CI 0.921～0.946)。结论 LEMON法在患者困难气道预测中有较好的临床效果。
英文摘要:
      Objective To evaluate the effect of the LEMON method in predicting difficult airway. Methods A total of 1 528 patients scheduled for elective surgery requiring tracheal intubation under general anaesthesia, 680 males and 848 females, aged 18-83 years, ASA physical status Ⅰ or Ⅱ, were enrolled in the study. We used the LEMON method to assess airway conditions before anaesthesia and recorded the scores. The primary end point was difficult tracheal intubation. The secondary end point was difficult laryngoscopy. Receiver operating characteristic (ROC) curve analysis and the area under the curve (AUC) were used to evaluate the clinical effect of the LEMON mothod. Results There were 37 cases with difficult tracheal intubation and 106 cases with difficult laryngoscopy. The incidence of difficult tracheal intubation and difficult laryngoscopy were 2.4％ and 6.9％, respectively. The area under the curve of the LEMON method for predicting difficult laryngoscopy and difficult tracheal intubation were 0.884 (95％CI 0.867-0.899) and 0.934 (95％CI 0.921-0.946), respectively. Conclusion The LEMON method has good clinical effect in predicting difficult airway.
