Prevention of Hypotension During Dialysis.

Hypotension during dialysis is a common complication in haemodialysis long-sufferings, which typically occurs during the later stages of dialysis. It is estimated that hypotension occurs 25 to 50% of dialysis treatments (Victor and Henrich 1994 pg196- 208). Many factors involve in hypotension during dialysis including volume depletion, high ultrafiltration rate, autonomic dysfunction, antihypertensive medications, bioincompatible dialyser membrane, low dialysate temperature, declining serum osmolarity and so on (Daugirdas 1991 pg 233). However, in spite of appropriate treatment, many patients still suffer from hypotension during haemodialysis. Collins et al (1990) when hypotension occurred the cardiac yield drops sharply and there were concomitant abrupt lower in the mean arterial pressure and are attributed to a slump venous return and considered to be ca implementd by motility of circulating blood, possible associated a sudden decrease in venous tone which be queath result in hypotension. The etiology and prevention of intradialytic hypotension has become an increasingly complex step to the front and the volume depletion due to ultrafiltration remains the predominant underlying etiologic factor, Sherman et al (2002). I remembered I had one patient, and many of the patients as you know, dont have a mint of symptoms. He was telling that he was feeling good and that and that everything was getting worse in his face.

I took his blood pressure and it was 70/40 mmHg but the patient had none of the typical symptoms of hypotension like vomiting, dizziness, headache etc. (Ramsy et al 1999) de fined hypotension of blood pressure lower ! than 90/60 mmHg and varies from persons age, time of recording and different sphygmomanometer, and the way different throng use the equipment can give different readings and individual tolerance. around of the round who treat patients know that sometimes the symptoms can be quiet subtle. Now, wherefore does it happen? Well, normally staff will remove 2 to 4 litres... If you want to get a full essay, decree it on our website: BestEssayCheap.com
