以往的研究证明,血透时血压的调节至少有6个重要的因素,即心输出量,交感神经张力,渗透压,超沪率,血清钾和循环中的血管活性物质。作者通过一例病人证明了血透时调节血压的另一个重要因素。患者男性,56岁。患慢性间质性肾炎、右侧肾乳头坏死作肾移植失败后长期进行维持血透已4年。因出现尿毒症心包炎考虑为透析不充分而改用大面积中空纤维型透析器透析。在透析过程中,频繁发生严重 Previous studies have shown that there are at least six important factors in the regulation of blood pressure during hemodialysis, namely, cardiac output, sympathetic tone, osmotic pressure, super-Shanghai rate, serum potassium and circulating vasoactive substances. The author demonstrates another important factor in regulating blood pressure when hemodialysis, through a patient. Male patient, 56 years old. Suffering from chronic interstitial nephritis, right renal papillary necrosis after long-term renal failure to maintain hemodialysis has been 4 years. Due to uremia pericarditis considered inadequate dialysis instead of using a large area hollow fiber dialyzer dialysis. In the process of dialysis, frequent serious
