Assessing the adequacy of dialysis and its relationship with kind of filter in patient under hemodialysis referred to 22-Bahman hospital of Gonabad

Inadequacy of dialysis is one of the main reason of mortality of dialysis patient and it is completely effective on forewarning. The aim of this study was to determine the adequacy of dialysis and its relationship with the kind of filter in patient referred to 22-Bahman hospital of Gonabad. This crossover study was done on all patients underlying dialysis that enrolled in the study in 22-Bahman Hospital. They were divided into two groups in simple random sampling. Each group involved 15 patients. In one group High flux filters and in another group low flux filters were used. The filters were changed after one month. Dialysis was done 3 times a week and lasted 4 hours. KT/V > 1.2 was considered as dialysis adequacy. The result showed 60% of the patients had dialysis adequacy >1.2. The means of KT/V was 1.34±0.42 in Low flux group. 80% of the patients had dialysis adequacy>1.2 and the means of kt/v was 1.44±0.32 in High flux group. There wasn’t a significant relationship between dialysis adequacy and the kind of filter (p=0.29). The means of Haemoglobin was 11. 49± 2.03 in Low flux group and 12.58±2.01 in High flux group. There was a significant relationship between Haemoglobin and the kind of filter. (p=0.04) In this study dialysis adequacy with High flux filter was desired in comparison with other studies. Although there wasn’t a difference between Low flux and High flux filter in dialysis adequacy, but the means of KT/V in High flux filter was more than Low flux filter and also the most patients that used High flux filter had enough dialysis adequacy (80% against 60%). The means of Haemoglobin in High flux was more than Low flux filter. So it is recommended to use High flux filter if there is any contradiction.
