Hypotension occurs in 20% of hemodialysis procedures.
To study the effects of midodrine on hypotension during hemodialysis.
Ten patients on chronic hemodialysis and with a history of hypotension during the procedure, were studied. They received midodrine 10 mg per os or placebo during 5 dialytic procedures each, in a double blind cross over design.
Blood pressure levels prior to dialysis were similar during the midodrine or placebo administration periods. During dialysis, systolic blood pressure fell 19.3 +/- 28 mmHg with midodrine and 23.4 +/- 28 mmHg with placebo. Diastolic blood pressure fell 7.3 +/- 11.5 mmHg with midodrine and 11.1 +/- 12 mmHg with placebo. The reduction in median arterial pressure was also less pronounced with midodrine.
Midodrine lessens the fall in arterial pressure during hemodialysis, in patients with symptomatic hypotension.
20%的血液透析过程中会出现低血压。
研究米多君对血液透析期间低血压的影响。
对10例接受慢性血液透析且在透析过程中有低血压病史的患者进行研究。采用双盲交叉设计，他们在每次5次透析过程中分别口服10毫克米多君或安慰剂。
在服用米多君或安慰剂期间，透析前的血压水平相似。透析期间，服用米多君时收缩压下降19.3±28毫米汞柱，服用安慰剂时下降23.4±28毫米汞柱。服用米多君时舒张压下降7.3±11.5毫米汞柱，服用安慰剂时下降11.1±12毫米汞柱。米多君使平均动脉压的降低也不那么明显。
对于有症状性低血压的患者，米多君可减轻血液透析期间动脉压的下降。
