[ effect of increasing blood flow rate on complications and dialysis adequacy in hemodialysis patients with low KT/V]

Insufficient dialysis, increasing complication, duration of hospitalized and expenditures in end stage renal disease patients. Several factors, including increased blood flow rate in the absence of complications can improve dialysis adequacy. So the aim of this study is to investigate the Effected of increasing blood flow rate on complications and dialysis adequacy in hemodialysis patients with Low KT/V. In this quasi-experimental study ,one group [pre-post test], all 45 hemodialysis patients, at 6 month bygone had 3 times in week, each time 3 to 4 hours of hemodialysis and KT/V was less than 1.2, in two sessions, that in first session adjustment blood flow rate on 230 ml/min and other increased 15% of blood flow rate in patients<65 Kg of body weight and 20% in patients>65 Kg in 2009 By the questionnaire and Check list were studied, and than we control KT/V and complications and finally by the statistical tests such Paird-Samples /-test and McNamara were compared. Mean systolic and diastolic blood pressure, incidence of hypotension, nausea, vomiting, muscle cramp did not have a significant difference within the tow status and the mean KT/V with the before and after increased blood flow rate ,was respectively 0.99 +/- 0.09 and 1.3 +/- 0.12 and results showed significant difference [P=0.001] comments from dialysis adequacy. Although the Complications during hemodialysis, while the two study conditions did not have a significant difference and also increase blood flow rate caused increase dialysis adequacy can be concluded that increased blood flow rate is effective on dialysis adequacy

[Knowledge of health care workers in hospitals of Zabol about the appropriate procedure for administration of blood and blood components]

Blood and blood components are used inappropriately in surgery and non surgery procedures. In medical settings, blood transfusion is important and its appropriate practice requires adequate expertise and knowledge; thus, this study is designed to assess the knowledge level of health care workers regarding appropriate use of blood and blood components in hospitals of Zabol. This is a descriptive study conducted on 122 nurses and health care workers. Data were collected by a questionnaire including 30 questions; they were then analyzed by SPSS version 11 software and Chi-Square. Findings showed that 26.2% of health care workers had a low level, 22.1% a moderate, and 51.6% an acceptable level of knowledge about appropriate use of blood. We did not find any significant correlation between the knowledge level of health care workers and their years in profession, age, gender, university degree, etc. Results strongly emphasized the need for a curriculum to promote knowledge of health care workers regarding blood transfusion because we found a low and moderate level of knowledge in approximately half of the participants
