血清尿素与肌酐在上下消化道大出血鉴别诊断中的意义

目的：探讨血清尿素与肌酐在上下消化道大出血鉴别诊断中的意义。方法：回顾性分析68例消化道大出血病例。结果：36例上消化道大出血病例中32例血清尿素〉8.9mmol/L,其X±SD为13.9±2.5,血清肌酐的X±SD为86.3±14.2。32例下消化道大出血病例中血清尿素的X±SD为5.8±2.4,血清肌酐的X±SD为84.5±12.5。上消化道出血组血清尿素与下消化道出血组比较,P〈0.01有显著差异。其血清肌酐间比较P〈0.05无显著差异。上消化道和下消化道出血组的血清肌酐与对照组比较均P〈0.01有显著差异。结论：在参考血清肌酐的情况下,血清尿素浓度有助于鉴别诊断上下消化道大出血。

Significance of Serum Urea and Creatinine in the Differentiation and Diagnosis of Massive Hemorrhage in Upper and Lower Digestive Canal

Objective：To explore the significance of serum urea and creatinine in the differentiation and diagnosis of massive hemorrhage in upper and lower digestive canal.Methods：68 cases with massive hemorrhage of digestive canal were retrospectively analyzed.Results In 36 cases with massive hemorrhage of upper digestive canal,the serum urea of 32 cases was8.9.1mmol/L,the was 13.9±2.5,the of serum creatinine was 86.3±14.2.The of serum urea in 32 cases with lower digestive canal was 5.8±2.4,the of serum creatinine was 84.5±12.5.The serum urea in upper digestive canal hemorrhage group and lower digestive canal hemorrhage group had obvious differences,P0.01,serum creatinine in the 2 groups had no obvious differences,P0.05.The serum creatinine in upper digestive canal hemorrhage group and lower digestive canal hemorrhage group had obvious differences with control group,P0.01.Conclusions：Serum urea was helpful to differentiate and diagnose massive hemorrhage in upper and lower digestive canal under the situation of referring serum creatinine.
