目的：对正常成年人主支气管的长度及内径进行测量,分析长度及内径与体质量指数(BMI)的相关性,为临床术前气管插管提供依据。方法100例正常成年男性和100例正常成年女性进行胸部 CT 扫描,利用三维后处理软件测量左、右主支气管开口处内径及左、右主支气管的长度,并与 BMI 进行相关分析。结果男性左、右主支气管的长度分别为(50.3±4.7)mm 和(19.7±5.2)mm,女性左、右主支气管的长度分别为(46.3±4.5)mm 和(18.2±4.1)mm,左主支气管(LMB)的长度是右主支气管(RMB)长度的3~4倍,男性左、右主支气管的横截面积分别为(175.3±29.6)mm2和(209.4±32.7)mm2,女性左、右主支气管的横截面积分别为(120.5±24.8)mm2和(144.4±33.7)mm2,实验者的主支气管的长度和年龄、身高、体重的 P 值分别为0.564、0.033和0.005；主支气管的长度同 BMI 之间没有显著的相关性。结论正常成年人双侧主支气管的长度及内径同 BMI 没有直接关系,BMI 不能作为选择双腔球囊插管(DLT)的参考标准,建议利用三维重建技术来确定主支气管的大小,以此来选择合适的 DLT。

Objective To measure the length and diameter of the main bronchus using three-dimensional reconstruction from spi-ral chest computerized tomography scans in Chinese patients,and to evaluate the relationship between the BMI of patients and the length and diameter of main bronchi in order to provide the basis for pre-operative tracheal intubation.Methods 100 males and 100 females,who were scheduled to undergo a chest CT scan for physical examination,the diameter at the carina of the left and right main bronchus were measured.The length of the main bronchi extending from the carina to the line that is vertical to the bronchial wall at the starting point from the branches of the upper lobe was measured at the workstation.Results the length of the men’s right and left main bronchus was (1 9.7±5.2)mm and (50.3 ±4.7)mm.the length of the women’s right and left main bronchus was (18.2±4.1)mm and (46.3±4.5)mm,The length of the left main bronchus(LMB)was about 3-4 times greater than right main bronchus(RMB).the cross-section of the men’s left and right main bronchus was (175.3±29.6)mm2 and (209.4±32.7)mm2 ,the cross-section of the women’s left and right main bronchus was (120.5±24.8)mm2 and (144.4±33.7)mm2 .There was no signifi-cant relationship between the length and diameter of main bronchi and the BMI of patients.Conclusion The results showed that there was no direct relationship between the diameter and the length of main bronchi and the BMI of patients.BMI is not the criteri-on for choosing double-lumen tube (DLT)size.We proposed that three-dimensional reconstruction be used to measure the size of the main bronchi and determine the optimal size of the DLT in a clinical setting.
