甲状腺癌手术全麻时困难气道发生率与性别的关系

 目的 探讨甲状腺癌手术全麻时困难气道发生率及与性别的关系。方法 回顾性研究2014-01至2014-12甲状腺癌手术146例，术前评估困难气道评分级，5分及以上使用视频喉镜插管，5分以下普通喉镜插管。记录诱导前、气管插管即刻、气管插管后5 min、手术开始血压、心率。统计困难气道的发生率，分析发生困难气道与性别的关系。结果 男性患者29例，发生困难气道7例;女性患者117例，发生困难气道8例，男性体重指数26.8±3.7;女性体重指数24.0±3.9。结论 甲状腺癌困难气道的总发生率为10.2%。男性高于女性，可能与男性体重指数高有关。

A retrospective study of incidence of difficult airway for thyroid cancer patrents and relationship with gender

Objective To investigate the incidence of difficult airway during general anesthesia in patients under going thyroid cancer surgery. Method A retrospective study was carried out for 146 cases of thyroid cancer surgery from January 2014 to December 2014 , glidescope was used for intubation when preoperative evaluation difficult airway score was 5 or above, while general laryngoscope was used when difficult airway score was below 5. Blood pressure and heart rate were recorded at the time points of before induction, endotracheal intubation, 5min after intubation, beginning of surgery. The probability of the occurrence of the difficult airway was counted, and relevant factors which may lead to difficult airway were analyzed. Result 7 cases of difficult airway develoved in 29 males and 8 cases of difficult airway in 117 females, body mass index was 26.8±3.7 for male cases and 24.0±3.9 for female cases.Conclusion The overall incidence of difficult airway is 10.2% for thyroid cancer. The incidence is higher for males than for females, which may be related to the higher male body mess index.
