Introduction: Studies have shown when hemodialysis treatment is sufficiently effective, complications of uremic syndrome, additional treatment costs and hospitalization length are reduced. Several methods have been proposed to improve hemodialysis adequacy. Objectives: In this study, the effects of the synchronic use of the stepwise profile dialysis fluid flow rate with increased blood flow rate (BFR) were studied on hemodialysis adequacy. Patients and Methods: This is a cross-over clinical trial study conducted on 34 hemodialysis patients selected from a hemodialysis center of Qazvin University of Medical Sciences, Qazvin, Iran. The patients were randomly allocated into two groups (n= 17 patients in each group) in two sequences. In the first sequence, the subjects received four routine hemodialysis sessions in group one and four hemodialysis sessions with the stepwise profile of the fluid flow rate with increased BFR in group two. In the second sequence, the treatment methods were exchanged. Hemodialysis sessions were performed in both sequences, consecutively. Each session was at least three hours. Hemodialysis adequacy was measured using Kt/V software on the hemodialysis machines after each session. Results: The mean score of dialysis adequacy was 0.89 in the routine method and 1.26 in the profile with increased BFR. There was a statistically significant difference between the methods (t= -7.9, df = 33, P < 0.001). Conclusion: The results of the study suggest that the stepwise profile of the dialysis fluid flow rate with increased BFR should be used synchronously to improve hemodialysis adequacy.
Introduction: Emotions have significant roles in different aspects of life such as coping with stressful and traumatic life events. Therefore, success in life depends not only on intellectual abilities, but also on emotion regulation competence. Emotion regulation is of greater importance in professions with high levels of daily occupational stress such as nursing. The aim of this study was to determine cognitive emotion regulation strategies used by a group of Iranian critical care nurses. Methods: This descriptive-analytic study was conducted on 193 critical care nurses. They were recruited through stratified random sampling from ICU, CCU, and Hemodialysis center and Emergency departments of six hospitals under supervision of Qazvin university of medical science, qazvin, Iran,. The 36-item Cognitive Emotion Regulation Questionnaire was used for data gathering. Descriptive statistics measures (frequency, mean, and SD) and inferential statistics (T test, Pearson correlation analysis) were used for data description and analysis. Results: There were significant differences among nurses of different units respecting the mean scores of strategies Acceptance (P = 0.002), Rumination (P = 0.001), Catastrophizing (P = 0.046), and Self-blame (P = 0.029). Age and work experience were correlated with acceptance and putting into perspective strategies while work experience was inversely correlated with rumination strategies.
