颈外动脉插管的应用解剖

目的:为提供临床颈外动脉插管的解部学依据,提高插管术的成功率。方法:利用经福尔马林固定的教学用的成人尸体30具。对60侧颈外动脉进行解剖、观察和测量。结果:颈外动脉的发起部位距甲状软骨上缘的距离为14.8±3.3mm,面动脉、颞浅动脉发起部位距颈总动脉分叉处的距离分别为68.0±1.8mm和65.4±13.4mm。结论:临床面动脉插管是从甲状软骨上缘15mm处将导管插入颈外动脉内。导管头端留在距插入部6.5mm处为最佳。

The Applied Anatomy of External Carotid Artery for Intubation

Objective: To supply the evidences of clinical anatomy of external carotid artery for intubation and to promote the correctness of successful intubation. Results: To dissect, observe and measure the 60 external carotid arteries in both sides of 30 bodies of adults for teaching which were fixed by formalin. Results: The distance from the occuring places of external arteries to the up-edges of the thyroid cartilages are 14.8 ± 3.3mm.The distances from the occuring places of the facial arteries and the supperficial temporal arteries to the branching positions of the chief carotid arteries are 68.0 ± 1. 8mm and 65.4 ± 13. 4mm respectively. Conclusion: Clinical intubation in the facial carotid arteries can be carried out in such a way as the catheter is inseted from the position which are 15mm on the up-edges of thyroid cartilages into the external carotid arteries. It would be better to leave the end of the catheter at the position which is 6.5mm from the inseting place.
