Venous pressure monitoring is an important indicator for the arteriovenous fistula evaluation. Direct static venous pressure monitoring is recognized as the most accurate way of venous pressure monitoring, which is widely used in the functional monitoring, functional evaluation of arteriovenous fistula, the diagnosis of complications and the evaluation of surgical efficacy. Venous pressure monitoring has obvious advantages and disadvantages, so it is necessary to improve relevant knowledge to correctly guide clinical diagnosis and treatment. In this paper, the study of static venous pressure monitoring of arteriovenous fistula was summarized, in order to improve the understanding of the significance and clinical application of static venous pressure monitoring of arteriovenous fistula.
ObjectiveTo study the clinical characteristics of elderly hemodialysis (HD) patients and discuss how to control their complications, in order to improve their quality of life and lower their mortality rate. MethodContrastive study and analysis were performed on the clinical data of 98 maintenance HD patients (between elderly and young HD patients) between January 2013 and January 2014. Complications, rate of hospitalization and mortality were analyzed during the follow-up of one year. ResultsThe ratio of hypertensive kidney disease and diabetic nephropathy, as primary disease of the elderly HD patients, gradually increased. More people chose to use semi-permanent jugular vein catheter for elderly HD patients. Compared with young HD patients, the levels of hemoglobin, albumin, serum creatinine, KT/v were lower in the elderly patients, and C-reactive protein was much higher (P<0.05). There was no significant difference in cholesterol, triglyceride, calcium, phosphorus, parathormone between the two groups (P>0.05). Dialysis-related hypotension and blocking of vascular access occurred more frequently in elderly HD patients. Hospitalization rate and mortality rate were higher in elderly HD patients (P<0.05). ConclusionsImproving nutritional status, keeping vascular access unobstructed for a long time and decreasing complications related to hemodialysis are helpful for elderly HD patients to enhance their quality of life and reduce the mortality rate.
Objective To assess the cost-utility study of renal transplantation compared with nemodialysis (HD) and peritoneal dialysis (PD). Methods A prospective study of end-stage renal disease patients was followed up for 3 months after renal replacement therapy. The study population included 196 patients (renal transplant [RT] n=63, hemodialysis [HD] n=82 and continious ambulatory peritoneal dialysis [CAPD] n=51) from 6 hospitals of Sichuan province. Health-related quality of life was assessed by using the WHOQOL-BRIEF questionnaire. Utility scores were obtained so as to conduct CUA (cost-utility analysis). Costs were collected from financial department and by patient interview. Results The utility values were 0.539 9± 0.013 for RT, 0.450 8± 0.014 for HD, 0.512 2±0.099 for CAPD, respectively. The mean direct cost of the first three months of renal transplant was significantly higher than dialysis (RT and CAPD). Over 3 months, the average cost per quality-adjusted life year (QALY) for patients after CAPD was lower than HD and RT. Compared to HD, incremental cost analysis showed that CAPD was more ecnomical than RT. Sensitive analysis showed that CAPD was more effective than RT when ΔQALY varied in the limit of 95% confidence interval. However, the cost-utility of RT vs HD and CAPD vs HD was varied with ΔQALY level. Conclusions Cost-utility analysis showed that CAPD was a more favorable cost-utility ratio when compared to RT at early stage RT vs HD and CAPD vs HD, but which cost-utility ratio is better, we can not draw a certain conclusion.
ObjectiveTo explore the risk factors for central venous catheter (CVC)-related infections and its Countermeasures, as CVC is an important vascular access for blood purification and is widely used in clinical applications, but catheter-related infection is one of the common severe complications. MethodsWe retrospectively analyzed the clinical data of 725 patients with complicated infections of indwelling center venous double lumen catheter treated between January 2009 and December 2012. ResultsAmong all 725 cases, 15 had catheter-related infection. There were one case of subcutaneous tunnel infection (staphylococcus aureus by the secretion culture, negative for blood culture), and 14 cases of positive blood culture including 9 staphylococcus aureus cases, 3 escherichia coli cases, 1 colorless bacillus case and 1 stenotrophomonas maltophilia case. Eight cases were cured by antibiotic therapy while antibiotics were invalid in the other 7 cases resulting in tube withdrawing. ConclusionThe central venous catheter-related infections are related to medical service ability, catheter indwelling position, indwelling time, hemodialysis adequacy, patients' general condition and personal hygiene. Taking relative measures in view of each factor is the key to prevent infections.
The patency of vascular access is of great significance to hemodialysis patients. Combining with guidelines and literature associated with vascular access for dialysis in recent years, the authors interpret the effectiveness and limitations of prophylactic drug strategies, including using fish oil, anticoagulation, anti-platelet, lipid-lowering agents, etc., in order to promote the proper use of these agents in clinical practice, and improve the effect of prophylaxis and treatment of vascular access dysfunction.
Objective To investigate the efficacy and prognostic factors of pars plana vitrectomy (PPV) in the treatment of proliferative diabetic retinopathy (PDR) with chronic renal failure (CRF). MethodsA retrospective study. From January 2016 to June 2021, a total of 82 eyes of 58 patients diagnosed with PDR combined with CRF and treated with PPV in Department of Ophthalmology, The Second Hospital of Hebei Medical University were included in the study. There were 32 cases in males and 26 cases in females. The mean age was (48.45±10.41) years. The course of renal failure was (4.15±3.23) years, and the course of diabetes was (14.45±6.71) years. All patients undergo best-corrected visual acuity (BCVA). The BCVA examination was performed using the international standard Snellen visual acuity chart, which was converted to logarithm of the minimum angle of resolution (logMAR) visual acuity for recording. The mean number of logMAR BCVA was 2.04±0.82 (0.7-2.8). The duration of vitreous hemorrhage averaged (2.65±1.55) months. There were 38 eyes (46.3%, 38/82) with traction retinal detachment; 32 eyes had a history of panretinal photocoagulation (PRP) treatment (39.0%, 32/82). All eyes were treated with 25G PPV. Patients with traction retinal detachment were treated with intravitreal injection of anti-vascular endothelial growth factor (VEGF) 3 days before surgery. Opacification of the lens affected the operation operator combined with phacoemulsification. Biochemical indexes such as hemoglobin, glycosylated hemoglobin, albumin, creatinine, uric acid, and alternative treatment (non-dialysis/hemodialysis/peritoneal dialysis) were collected. Postoperative follow-up time was ≥6 months. χ2 test or Fisher's exact test were used for comparison between groups. A logistic regression model was used for multivariate analysis, and Spearman correlation analysis was used to evaluate the correlations between variables. ResultsAt 6 months after surgery, the mean logMAR BCVA was 1.16±0.57. Compared with logMAR BCVA before surgery, the difference was statistically significant (t=－0.837, P＜0.001); 44 eyes had BCVA ≥0.1 and 38 eyes had BCVA ＜0.1. Postoperative vitreous hemorrhage (PVH) was observed in 17 eyes after surgery (20.7%, 17/82). PVH occurred in 15 (46.9%, 15/32), 1 (2.3%, 1/44), and 1 (16.7%, 1/6) eyes in patients without dialysis, hemodialysis and peritoneal dialysis, respectively. There was significant difference between those without dialysis and those on hemodialysis (χ2=26.506, P＜0.05). There was no significant difference between peritoneal dialysis patients and those without dialysis and hemodialysis patients (χ2=2.694, 2.849; P＞0.05). PVH occurred in 3 (10.0%, 3/30) and 14 (27.0%, 14/52) eyes of vitreous cavity filled with silicone oil and perfusion fluid, respectively. The difference was statistically significant (χ2=3.315, P＜0.05); 1 (33.3%, 1/3) and 10 (71.4%, 10/14) eyes were treated with PPV again, respectively, and the difference was statistically significant (P＜0.05). Neovascular glaucoma (NVG) occurred in 12 eyes (14.6%, 12/82). Logistic regression analysis showed that age [odds ratio (OR) =0.911, P＜0.05], diabetic retinopathy (DR) stage (OR=7.229, P＜0.05), renal failure duration (OR=0.850, P＜0.05), operation time (OR=1.135, P＜0.05) was an independent risk factor for poor vision prognosis. Diabetes duration (OR=1.158, P＜0.05), renal failure duration (OR=1.172, P＜0.05) and alternative therapy were independent factors affecting the occurrence of PVH. Diabetes duration (OR=1.138, P＜0.05) and renal failure duration (OR=1.157, P＜0.05) were independent risk factors for postoperative NVG. Spearman correlation analysis showed that PVH was strongly correlated with post-operative NVG (r=0.469, P＜0.01). There was no significant correlation between blood glucose, hemoglobin, creatinine and blood urea nitrogen and prognosis of postoperative vision, PVH and NVG occurrence (P＞0.05). ConclusionsIn PDR patients with CRF, DR Stage, age, renal failure course and operation duration are correlated with vision prognosis. Compared with those who do not receive alternative therapy, hemodialysis treatment can reduce the occurrence of PVH and NVG after surgery.
During the medical rescue after Wenchuan earthquake, based on the design and implementation of the management process of blood purification equipment, we gave the top priority to those patients with post-disaster crush syndrome to ensure their hemodialytic treatment. Through strict management of blood purification technology, the outcomes of these patients have been fundamentally improved and the incidence of complications was substantially reduced. Safe and effective hemodialytic treatment have been administered to 77 patients with crush syndrome (813 case-times).
Objective To explore the vitamin K level in Chinese maintenance hemodialysis (MHD) patients. Methods MHD patients and healthy subjects from our outpatient clinic were enrolled from 1 to 30 in March 2016. Demographic data was collected. Fasting serum samples from all subjects were collected for biochemistry tests and the measurement of known vitamin K-dependent proteins, i.e. matrix Gla protein (MGP), osteocalcin (OC) and uncarboxylated osteocalcin (ucOC). We also quantified the fraction of ucOC of total OC (%ucOC). Differences of these parameters between the two groups were analyzed. Results We enrolled 70 MHD patients as a test group and 70 healthy subjects as a control group. There was no significant difference in MGP between MHD group and the control group [(4.1±2.2) vs. (4.4±1.0) pg/mL, P=0.441]. The value of %ucOC was significantly higher in the MHD group than that in the control group [(79.3±19.3)% vs. (51.9±13.0)%, P<0.001]. Conclusions Deficiency of vitamin K appears common in Chinese MHD patients. Besides pathological reasons, dietary habit may also contribute to this phenomenon.
ObjectiveTo investigate the application and effect of quality control circle (QCC) in the management of hand hygiene for nurses in hemodialysis center. MethodsQCC was applied in the management of hand hygiene in hemodialysis center from March 2013 to February 2014. Factors affecting the compliance and correctness of hand hygiene in hemodialysis nurses were analyzed, and counter measurements were established and applied. Moreover, effect of QCC management was also assessed. ResultsAfter the application of QCC, the compliance and correctness of hand hygiene in hemodialysis nurses increased significantly from 41.02% to 88.46% (P<0.05) and 46.88% to 91.30% (P<0.05), respectively. Moreover, maneuver application, team spirit, professional knowledge, communication and cooperation among nurses were also increased by QCC management. ConclusionThe application of QCC can not only increase the compliance and correctness of hand hygiene in hemodialysis nurses but also improve team cohesiveness, which is worth recommendation and promotion.
Objective To understand the cognition and acceptance of community hemodialysis centers among hemodialysis patients in Yangzhou, and to provide theoretical basis for the development of community hemodialysis centers. Methods A cluster random sampling method was used to select 400 maintenance hemodialysis patients treated in various areas of Yangzhou in April 2021 for a questionnaire survey to analyze the influencing factors of patients’ medical treatment behavior. Results A total of 390 valid questionnaires were recovered, with an effective recovery rate of 97.50%. Among the patients, 40.51% were very concerned about the construction of hemodialysis centers in the community, 56.67% understood the relevant policies, and 56.92% of the patients were willing to choose the community for dialysis treatment. The results of logistic regression analysis showed that the main factors affecting whether patients choose community for hemodialysis treatment include the patients’ residence [Jiangdu vs. Guangling: odds ratio (OR)=7.183, 95% confidence interval (CI) (2.010, 25.674), P=0.002; Gaoyou vs. Guangling: OR=22.512, 95%CI (7.201, 70.373), P<0.001; Yizheng vs. Guangling: OR=25.137, 95%CI (7.636, 82.744), P<0.001; Baoying vs. Guangling: OR=23.784, 95%CI (7.795, 72.569), P<0.001], degree of concern [some concern vs. very concerned: OR=0.267, 95 %CI (0.137, 0.521), P<0.001; not very concerned vs. very concerned: OR=0.062, 95%CI (0.023, 0.168), P<0.001; not concerned vs. very concerned: OR=0.101, 95% CI (0.023, 0.439), P=0.002], awareness [somewhat know vs. know very well: OR=0.025, 95%CI (0.002, 0.318), P=0.004; don’t know very well vs. know very well: OR=0.035, 95%CI (0.003, 0.439), P=0.009; don’t know vs. know very well: OR=0.006, 95%CI (0.000, 0.084), P<0.001]. Conclusions Hemodialysis patients in Yangzhou have a low level of awareness and acceptance of community-based hemodialysis centers. The patients’ residence, degree of attention and awareness of community-based hemodialysis center directly affect whether they choose the community for treatment. The relevant departments and medical institutions can start from the factors that affect patients’ choice of medical treatment, further strengthen the publicity of community dialysis, optimize the allocation of medical resources, and improve the capacity of community health services.
