研究新生儿气管、主支气管的长度、管径、气管叉夹角及毗邻关系。方法：在手术显微镜下对气管、主支气管及毗邻关系进行观测。结果：气管长（３７．０５±３．８７）ｍｍ，左主支气管长（１６．９６±２．５２）ｍｍ，右主支气管长（９．３８±１．６１）ｍｍ，气管内周径、内横径、内前后径分别是（１５．３２±１．１６）ｍｍ、（４．６９±０．４１）ｍｍ、（３．６２±０．４６）ｍｍ，左主支气管内周径、内横径、内前后径分别是（１０．３７±１．５５）ｍｍ、（３．２２±０．４１）ｍｍ、（２．４２±０．４２）ｍｍ．右主支气管内周径、内横径、内前后径分别是（１１．７７±１．３２）ｍｍ、（３．７４±０．３９）ｍｍ、（２．８７±０．４７）ｍｍ，气管叉夹角为（７４．９３±４．８４）°。颈段气管前方颈前静脉弓出现率为１００％．胸腺均伸入到颈静脉切迹上方，头臂干、甲状腺下动脉、左头臂静脉、甲状腺下静脉的出现率分别是（２６．６６±８．０７）％、（２６．６６±８．０７）％、（１３．３３±６．２１）％、１００％。结论：气管的长度随身高增加而加长，左、右主支气管与气管长轴的夹角不等并非生后发育所致，甲状腺下动脉、头臂千出现率较高。
Study neonatal trachea, the length of the main bronchus, diameter, tracheostomy angle and the adjacent relationship. Methods: The trachea, main bronchus and adjacent relationship were observed under a surgical microscope. Results The length of trachea (37.05 ± 3.87) mm, length of left main bronchus (16.96 ± 2.52) mm, length of right main bronchus (9.38 ± 1.61) mm, tracheal inner diameter, The internal diameter and internal diameter of the left main bronchus were (15.32 ± 1.16) mm, (4.69 ± 0.41) mm and (3.62 ± 0.46) mm, The transverse diameter and anteroposterior diameter were (10.37 ± 1.55) mm, (3.22 ± 0.41) mm and (2.42 ± 0.42) mm, respectively. The inner diameter, inner diameter and inner diameter of right main bronchus were (11.77 ± 1.32) mm, (3.74 ± 0.39) mm and (2.87 ± 0.47) mm respectively. The trachea The fork angle is (74.93 ± 4.84) °. Cervical anterior cervical arch in front of the anterior arch vein was 100%. The thymus extended into the jugular vein notch. The incidences of the brachiocephalic trunk, inferior thyroid artery, left brachiocephalic vein and inferior thyroid vein were (26.66 ± 8.07)% and (26.66 ± 8)%, respectively. 07)%, (13.33 ± 6.21)%, 100%. Conclusion: The length of the trachea increases with the increase of height. The angle between the main bronchus and trachea of left and right trachea is not due to the development after birth. The occurrence rate of the thyroid artery and the first arm is high.
