摘　　要：目的 探讨一种判断气管插管深度的新方法及其可行性。方法 选择全身麻醉下行妇科腹腔镜手术的成年患者50例,ASA分级Ⅰ-Ⅱ级。在气管插管前,将盲探气管插管装置中的光索置入气管导管,测量套囊中点至气管导管尖端的距离。常规全麻诱导气管插管后置入同样距离的光索,根据光点位于胸骨上窝中点调整气管导管深度。记录气管导管尖端距离门齿的距离，利用纤维支气管镜测量气管导管尖端至隆突的距离。结果 气管导管尖端距离门齿和隆突的距离分别为（20.5±1.1）cm和（4.1±1.1）cm。结论 采用光索定位气管导管套囊位于胸骨上窝,有助于判断气管插管深度。Objective To explore a new method of the judgment for the depth of endotracheal intubation and its feasibility. Methods Fifty female patients with ASA ofⅠ-Ⅱwere conducted general anaesthesia for gynecological laparoscopic surgery.The distance between endotracheal tube tip and cuff was recorded with a light-guided catheter before anesthesia.After the rapid sequence induction,the light-guided catheter was inserted into endotracheal tube according to the length recorded.The distance from upper incisors and carina to endotracheal tube tip was recorded, respectively. Results The distance from the upper incisors and carina to endotracheal tube tip was （20.5±1.1） cm and （4.1±1.1） cm,respectively. Conclusions Using a light-guided catheter location suprasternal fossa attribuated judgment the depth of endotracheal intubation.
