概念 创伤后急性肾功能衰竭(PTARF)是创伤病人的严重并发症。常由复合因素所致,能发生在创伤时,亦出现在其后的治疗过程中。病理变化虽属可逆性的,但诊治不当死亡率极高。病人具有肾小球滤过率每分钟突然少于1～2毫升,血尿素氮和肌酐显著上升的特征。并有由此而致的氮质血症、体液过多、高血钾、代谢性酸中毒、创面延迟愈合及凝血机制失常等表现。故不是一个单独的疾病,而是一种复杂多变的临床综合症。
The concept of posttraumatic acute renal failure (PTARF) is a serious complication of trauma patients. Often caused by a combination of factors that can occur in the trauma, also appeared in the subsequent treatment process. Although pathological changes are reversible, but the diagnosis and treatment of improper mortality is extremely high. Patients with glomerular filtration rate suddenly less than 1 to 2 ml per minute, blood urea nitrogen and creatinine increased significantly. And resulting from azotemia, body fluid too much, hyperkalemia, metabolic acidosis, delayed wound healing and coagulation disorders and other performance. It is not a single disease, but a complex and ever-changing clinical syndrome.
