Objective To compare the clinical effect of continuous renal replacement therapy (CRRT) and intermittent hemodialysis (IHD) in the treatment of severe acute renal failure (ARF). Methods A hundred patients with severe ARF treated between May 2011 and December 2014 were chosen to be the study subjects. According to the order of admission, they were divided into control group and observation group with 50 patients in each. Patients of the control group underwent IHD, while those in the observation group underwent CRRT. Serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine clearance rate (Ccr), treatment effective rate and survival rate were compared between the two groups before and after the treatment. Results Scr, BUN and Ccr were all improved after treatment in both the two groups. However, Scr, BUN and Ccr in the observation group [(225.1±162.7) μmol/L, (14.2±9.3) mmol/L, (23.4±10.5) mL/min] were significantly better than those in the control group [(588.4±183.6) μmol/L, (29.1±10.4) mmol/L, (15.9±8.2) mL/min]. The treatment effective rate and patients’ survival rate in the observation group were respectively 60% and 70%, both significantly higher than those in the control group (40% and 52%) All the differences were significant (P<0.05). Conclusion CRRT is superior in the treatment of severe ARF with a higher survival rate of the patients, which is worthy of clinical promotion.
ObjectiveTo discuss and analyze the sense of dignity and its influencing factors of maintenance hemodialysis (MHD) patients.MethodsPatients with MHD in hemodialysis center of West China Hospital of Sichuan University were selected from November 2019 to January 2020. Patients were selected by convenience sampling. The patients were investigated with Patient Dignity Inventory (PDI), Connor-Davidson Resilience Scale (CD-RISC) and Hospital Anxiety and Depression Scale.ResultsA total of 150 patients were included. The average scores of CD-RISC, anxiety, depression and PDI were 61.20±14.54, 4.97±1.38, 5.90±2.42 and 41.32±16.24, respectively. Among them, 121 cases (80.67%) had mild dignity impairment, 22 cases (14.67%) had moderate dignity impairment, 6 cases (4.00%) had severe dignity impairment, and 1 case (0.67%) had very serious dignity impairment. The results of multiple linear stepwise regression showed that depression, economic burden, social support, and vascular access were all positive predictors of esteem scores (P<0.001).ConclusionsClinical nurses can aim at the main factors affecting the sense of dignity of MHD patients. And individualized nursing plan and intervention measures can be formulated to improve the sense of dignity of patients and improve the quality of life of maintenance hemodialysis patients.
Most patients with end-stage renal disease choose maintenance hemodialysis to prolong survival. The clinical application of exercise therapy has a definite effect on maintenance hemodialysis patients, and can effectively improve their quality of life and promote rehabilitation. Individualized exercise therapy under the guidance of medical professionals has positive effects on patients’ physical and mental rehabilitation. This paper mainly summarizes the status of exercise, factors affecting exercise, exercise therapy, exercise and rehabilitation of maintenance hemodialysis patients, and reviews the impact of exercise therapy on the physical and mental health of maintenance hemodialysis patients, in order to provide some references for clinical intervention and prognosis studies.
Blood pressure variability (BPV) is a novel predictor related to blood pressure level, and a large number of studies based on the hypertension cohort have shown that BPV is an independent predictor of target organ damages and cardiovascular adverse outcomes. Due to the significant hemodynamic changes, BPV in patients with chronic kidney disease (CKD) and hemodialysis is higher than the simple hypertension cohort, suggesting that BPV may be of great significance to patients with chronic kidney disease and hemodialysis. In recent years, studies based on CKD and hemodialysis cohort have published in succession whose results revealed that BPV of this cohort is of great prognostic significance for predicting target organ damages and cardiovascular disease risks. This article aims to provide an overview on these research, so as to survey and predict the clinical significance of BPV in CKD and hemodialytic patients.
ObjectiveTo preliminarily explore the effect of Osteoporosis Self-assessment Tool for Asians (OSTA) and Fracture Risk Assessment Tool (FRAX) on predicting osteoporosis and osteoporosis fracture in postmenopausal patients with maintenance hemodialysis (MHD).MethodsThirty-six postmenopausal patients undergoing MHD from August 2017 to October 2018 in Hemodialysis Center of Nephrology Department, West China Hospital of Sichuan University were selected. Relevant data such as age, height, and weight were collected. OSTA index and the 10-year probability of major osteoporotic fractures and 10-year probability of hip fractures of FRAX score were calculated. Bone mineral densities (BMD) of the hip and lumbar spine were measured by dual energy X-ray absorptiometry (DXA) at the same time. The value of OSTA index and FRAX scale in evaluating the risk of osteoporosis predicated on T value ≤−2.5 determined by DXA BMD and fracture in postmenopausal patients with MHD were analyzed.ResultsThe DXA BMD of the 36 patients showed that 50.0% (18/36) had a T value≤−2.5, and 30.6% (11/36) had a fracture history. BMD in postmenopausal patients with MHD was negatively correlated with FRAX score (model without BMD values), and positively correlated with OSTA index. The sensitivity and specificity of OSTA in the prediction of osteoporosis were 94.4% and 61.1%, respectively; and the sensitivity and specificity of FRAX (the model without BMD values) in the prediction of osteoporosis were 88.9% and 50.0%, respectively. The FRAX score with or without BMD had the same clinical value in predicting osteoporosis.ConclusionsPostmenopausal MHD patients have a higher risk of osteoporosis and fracture. Both OSTA index and FRAX scale can predict osteoporosis risk among postmenopausal MHD patients, and the FRAX scale with or without BMD has the same clinical value in predicting osteoporosis risk. In clinical work, for primary hospitals and dialysis centers lacking DXA, preliminary screening of osteoporosis in MHD patients can be performed with OSTA and FRAX scales.
ObjectiveTo investigate the effect of 24-week intradialytic progressive resistance exercise on hemoglobin and iron metabolism in maintenance hemodialysis (MHD) patients.MethodsFrom April to May 2019, 62 MHD patients were enrolled and randomly assigned into exercise group (n=31) and control group (n=31). Both groups of patients received regular routine hemodialysis, on that basis, patients in the exercise group completed intradialytic resistance exercise three times per week for 24 weeks. Each exercise included 8-10 muscle groups (grasping the grip ring with both hands, flexion and extension of the elbows and shoulders on the non-vascular side and lower limbs with sandbag), 3 sets of 15 repetitions with a rest of 1-2 min between 2 sets. Exercise began with a low load, the sandbag weight was gradually increased, and the Borg score was aimed to be 11-13 points after exercise. Hemoglobin, serum ferritin, transferrin saturation, serum creatinine, high-sensitivity C-reactive protein, urea clearance index, recombinant human erythropoietin (rHuEPO) dosage at baseline and after 24 weeks, as well as the cumulative iron supplement dose and hemoglobin variation of the two groups during the study period were evaluated.ResultsThere were 20 patients in the exercise group and 30 ones in the control group who completed the study. After 24 weeks of progressive resistance exercise, the medium (lower quartile, upper quartile) of the amount of rHuEPO in the exercise group decreased from 6 000 (6 000, 9 000) U/week to 6 000 (4 500, 7 125) U/week (Z=−2.599, P=0.009), while that in the control group had no statistically significant difference (Z=−1.340, P=0.180); there was no statistically difference in hemoglobin, hemoglobin coefficient of variation, serum ferritin, transferrin saturation, or 24-week cumulative iron supplementation between the two groups.ConclusionIntradialytic progressive resistance exercise can reduce the amount of rHuEPO in MHD patients, which is benefitial to optimizing the management of hemoglobin.
ObjectiveTo explore the clinical curative effect of high flux hemodialysis on diabetic nephropathy (DN) and impact on patients' insulin resistance (IR). MethodsA total of 96 patients with DN meeting the inclusion criteria treated between January 2013 and January 2014 were selected. The patients were randomly divided in to the observation group and control group with 48 in each. The control group received low flux hemodialysis, while the observation group underwent high flux hemodialysis. Before the treatment and in the first half of the year after the treatment, the clinical renal function and inflammatory indexes, lipid metabolism, and glucose metabolism related markers were recorded, and IR index (HOMA-IR) were calculated and compared. ResultsBefore and after the treatment, the Kt/V showed no significant change in the two groups (P > 0.05). Serum creatinine levels was lower after the treatment compared with that before the treatment in both of the two groups; in the observation group, C-reactive protein, interleukin-6 and tumor necrosis factorαwere significantly lower than those before the treatment and than those in the control group after the treatment (P < 0.05). HOMA-IR and fasting insulin levels in the observation group after the treatment were significantly lower than those before the treatment and than those in the control group after the treatment (P < 0.05). No significant changes of fasting plasma glucose and glycosylated hemoglobin levels in the two groups before and after the treatment in patients were found (P > 0.05). ConclusionHigh flux hemodialysis therapy is effective on DN, which can effectively remove the body and large molecular type of inflammatory mediators, alleviate the micro inflammatory state, improve the IR status and correct the lipid metabolic abnormalities.
Objective To understand the current situation of eHealth literacy of maintenance hemodialysis (MHD) patients and analyze the influencing factors to improve the eHealth literacy of MHD patients. Methods Using cross-sectional survey method, MHD patients in West China Hospital of Sichuan University were selected as the subjects between February and April 2022. eHealth Literacy Scale (eHEALS) was used to investigate the status of eHealth literacy, and the influencing factors of MHD patients were analyzed. Results A total of 194 MHD patients were investigated. The total eHEALS score of MHD patients was 24.55±9.14. The results of generalized linear regression showed that education level, medical payment method, age, frequency of internet forums, interest in internet health knowledge search, and Baidu search engine (a common channel for searching disease information online) were the influencing factors of MHD patients’ electronic health literacy. Conclusion The electronic health literacy level of MHD patients is low, so renal medical staff should pay attention to the electronic health literacy of MHD patients and develop targeted interventions to help patients better manage their own health problems.
Objective To study the influence of calcium acetate tablets combined with compound alpha-keto acid on calcium and phosphorus metabolism in maintenance hemodialysis (MHD) patients. Methods A total of 112 MHD patients with hyperphosphatemia treated between May 2014 and May 2015 were included in this study. Based on random number table method, they were divided into calcium acetate group (n=37), compound alpha-keto acid group (n=36) and combined drug use group (n=39). All the patients were given a low protein diet. Twelve weeks after treatment, we compared the calcium and phosphorus metabolic indexes, nutrition indicator levels and adverse reactions within and across the three groups. Results Before treatment, there was no significant difference among the three groups in terms of serum calcium, phosphorus, calcium-phosphorus product, and parathyroid hormone (PTH) level (P>0.05). After treatment, the combined drug use group had significantly lower levels of serum phosphorus, calcium-phosphorus product and PTH than the other two groups (P<0.05). Before treatment, the levels of creatinine, serum total protein and albumin were not significantly different among the three groups (P>0.05). After treatment, the serum total protein and albumin level in the combined drug use group were significantly higher than those in the other two groups (P<0.01). Three was no significant difference among the three groups in terms of adverse reactions (P>0.05). Conclusions For MHD patients with hyperphosphatemia, the combined use of calcium acetate tablets and compound alpha-keto acid is better than the use of single drugs, which can effectively improve patients’ symptoms and reduce the level of serum phosphorus with high security. It is worthy of clinical recommendation.
Blood pressure variability (BPV) refers to the fluctuations of blood pressure in a certain period of time. In recent years, BPV is becoming a predictive marker for cardiovascular events. Given the hemodynamic and internal environmental change brought by hemodialysis as well as the complex complications, hemodialysis patients always have complex BPV. Nowadays there is no consensus on an optimal standard to evaluate BPV in hemodialysis population. Metrics usually used are as follows: blood pressure change during a certain period of time, standard deviation, coefficient of variation, variation independent of mean, average real variability, weighted mean of daytime and night-time standard deviation, residual derived from generalized linear models, and residual standard deviation. Impact factors of BPV in hemodialysis patients include age, ultrafitration volume, hemodialysis frequency and time length, peripheral vascular disease, serum calcium, antihypertensive drugs and so on. Recent studies showed significant associations between both long-term and short-term BPV with prognosis of hemodialysis patients. This review focuses on the evaluation methods, the influencing factors and the impact on prognosis of BPV.
