摘　　要：采用血清尿素氮(BUN)/肌酐(Cr)值(mmol/mmol)对194例急性消化道出血患者的出血部位鉴别及影响因素进行了探讨。上消化道出血、空肠出血及胃肠道广泛出血患者的BUN/Cr值明显增高,而回肠和大肠出血者无明显改变。上消化道出血时、BUN/Cr值随出血量的增大而增高。该比值可排除肝、肾功能不全对血清BUN浓度变化的影响。动态观察发现,上消化道出血后该比值的增高早于BUN浓度的增高。结果表明,血清BUN/Cr值是一项鉴别上、下消化道出血简单、灵敏的方法。The application of the ratio of serum urea ni-trogen to creatinine(BUN/Cr)in identifying thesource of acute gastrointestinal hemorrhage wasreviewed in 194 cases.The ratio was significantlyincreased in upper jejunal and extensivegastrointestinal bleeding,but not changed in ilealand large intestinal hemorrhage.The ratio wasprogressively increased with increasing blood lossin the upper gastrointestinal tract,With the use ofthe ratio of BUN/Cr,the influence of liver andkidney dysfunction on serum BUN concentrationcould be excluded.Dynaimic observation revealedthat the increase of the ratio of BUN/Cr was ear-lier than the elevation of BUN concentration inupper gastrointestinal hemorrhage.It is shown thatthe ratio is a simple and an accurate parameter indistinguishing between upper and lower gastro-intestinal hemorrhage.
