摘　　要：目的探讨成人上腔静脉下段后前位胸片投影是否与性别、年龄、身高、体重相关,以期提高床旁PICC体外测量的准确性。方法成人体检资料100份,在后前位胸片上测量上腔静脉下段中点至右锁骨内端下缘距离(即横L体外测量法垂直段距离,以下简称"垂直段距离"),上腔静脉下段中点所在前肋肋单元平面,各数据会同性别、年龄、身高、体重,利用IBM SPSS Statistics v19统计软件作Pearson相关分析。结果上腔静脉下段中点所在前肋肋单元平面与性别、年龄、身高、体重无显著相关(r=-0.196～0.130,P=0.051～0.936);垂直段距离与身高、性别显著相关(r=0.197、-0.339,P=0.049、0.001),与年龄及体重无关(r=0.052、-0.066,P=0.604、0.512)。结论成人上腔静脉下段投影存在个体差异,相关因素复杂,难以通过性别、年龄、身高、体重来提高床旁PICC体外测量的准确性。Objective The aim of this study was to explore the relationship between the variables （age, sex, height, weight） and the lower segment of superior vena cava on the posteroanterior thorax radiograph, and to improve the in-vitro measurements accuracy of beside PICC. Methods The data of 100 cases adults physical examination were collected in TaiZhou hospital. We measnred the distance between the middle of the lower segment of superior vena eava to the inner side of the right clavicle, observed the front rib units which was projected the middle of the lower segment of superior vena cava, and then analyzed the correlation between the data （distance between vertical segment, the front rib units） and the variable （age, sex, height, weight） with IBM SPSS Statistics v19 software. Results The front rib units planes was no sig nificant correlation with sex, age, height and weight （ r =-0. 196-0. 130, P =0. 051-0. 936）. The distance between vertical segment was obvious correlation with body height and sex （ r =0. 197, -0. 339, P =0. 049,0. 001） and no significant correlation with age and body weight（ r =0. 052, -0. 066, P=0. 604, 0. 512）. Conclusion The projection of the lower segment of superior vena cava has the individual differences, which is affected by many factors besides age, sex, height and weight. Thus, it is difficult to improve the in-vitro measurements accuracy of beside PICC by analyzing the age, sex, height and weight of the patient.
