Objective To summarize our experience of cardiovascular surgery for patients dependent on dialysis, and evaluate its safety and efficacy.?Methods?Clinical data of 10 consecutive patients dependent on maintenance dialysis underwent cardiovascular operations between Dec. 2004 and April 2011 in Peking Union Medical College Hospital were analyzed retrospectively. There were 6 male and 4 female patients, aged between 23 to 71 （57.6±13.2） years. They were put on dialysis 3-98 （25.2±30.6） months prior to operation due to diabetic nephropathy in 6 patients, chronic glomerulitis in 3 patients and systemic lupus erythemus in 1 patient, and 8 were dependent on hemodialysis and 2 on peritoneal dialysis. Five patients underwent coronary artery bypass grafting, one underwent Bentall procedure，two underwent aortic valve replacement, one underwent mitral valve replacement, and one underwent superior vena cava thrombectomy and patch repair. Patients underwent dialysis on the day before elective operation, followed by continuous ultra-filtration during cardiopulmonary bypass, and then bedside heparin-free continuous veno-venous hyperfiltration-dialysis started 5-32 hours after the operation. Conventional peritoneal dialysis or hemodialysis was resumed 4-7 days after operation.?Results?All operations were successfully completed. Cardiopulmonary bypass time was （125.8±33.5）minutes, aortic clamp time was（77.2±25.5） minutes. One in-hospital death occurred due to septic shock after deep chest wound infection. One patient underwent re-exploration due to pericardial temponade to achieve hemostasis. Three patients experienced atrial fibrillation and were all converted to sinus rhythm by amiodarone. Nine patients recovered to discharge and were followed-up for 8-76 months. Two late deaths occurred due to intracranial hemorrhage and liver carcinoma respectively. Seven survived patients were all in New York Heart Association grade II functional class, and none of them experience major advertent cardiac events related to grafts or prosthetic valve. One patient switched to hemodialysis 14 months after discharge due to peritonitis.Conclusion?Cardiovascular surgery can be practiced in patients dependent on maintenance hemodialysis or peritoneal dialysis with appropriate peri-operative management, so that symptoms can be relieved and quality of life improved.
ObjectiveTo investigate the current situation of stress load and professional benefit of hemodialysis nurses during the outbreak period and the remission period of coronavirus disease 2019 (COVID-19) epidemic, and discuss the differences in stress load and professional benefit of hemodialysis nurses between the two periods.MethodsIn February 2020, 119 hemodialysis nurses from three hemodialysis centers in Sichuan Province were selected as the respondents. Using the Stress Overload Scale and the Questionnaire of Nurses’ Perceived Professional Benefits, questionnaire survey was conducted in February 2020 and April 2020, respectively. Paired-sample t test was used for analysis.ResultsA total of 109 valid questionnaires were collected. The scores of stress load of hemodialysis nurses in outbreak period and remission stage were 3.00±1.26 and 2.17±1.16, respectively, of which the scores of event load dimension were 3.49±1.15 and 2.31±1.27, respectively, and the scores of individual vulnerability dimension were 2.59±1.19 and 2.05±1.06, respectively; the professional benefit scores of hemodialysis nurses in outbreak and remission were 4.19±0.83 and 4.21±0.78, respectively. The difference in stress load of the same group of hemodialysis nurses between different time periods was statistically significant (P<0.05), while there was no significant difference in professional benefit (P>0.05).ConclusionsDuring the outbreak of COVID-19 epidemic, the stress load of hemodialysis nurses was ata medium level, and that in the remission stage of COVID-19 epidemic was at a low level; the professional benefit of nurses in the outbreak and remission period was at a high level. The stress load status of hemodialysis nurses was different between different periods of the epidemic. We should take incentive mechanism or targeted psychological intervention measures to improve the professional benefit level of nurses.
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.
Although the recent studies have concerned the pathogenesis and therapeutic strategies of acute kidney injury (AKI), the mortality of AKI is still terribly high, and it is still one of the most important death factors in the intensive care unit. There is no doubt that early verdict of AKI, is good for a more aggressive treatment and can promise an improved prognosis for AKI patients. Serum creatinine level, serving as the gold standard for diagnosis of kidney injury, cannot meet current clinical work in its sensitivity and specificity of diagnosis of early AKI. Over the past decades, researchers worked to find and verify novel AKI biomarkers, including neutrophil gelatinase associated lipocalin, interleukin-18, kidney injury molecule-1 and cystatin-C, which were proved to be the potential reliable predictor of AKI development and prognosis, and were of great importance to the early diagnosis and clinical monitoring of AKI. This paper reviews the main studies on these novel prognostic predictors of AKI over the decades and evaluates their roles and limitations in early diagnosis and clinical prognosis prediction.
Objective
To investigate the therapeutic effect of continuous renal replacement therapy (CRRT) plus hemoperfusion (HP) on patients with diabetes and uremic encephalopathy.
Methods
Fifty-five patients with diabetes and uremic encephalopathy from January 2010 to December 2017 were retrospectively collected in this study and divided into CRRT plus HP (CRRT+HP) group (n=28) and hemodialysis (HD) plus HP (HD+HP) group (n=27). The changes of vital signs, related biochemical indicators before and after treatment and curative effects were compared between the two groups.
Results
The two groups were comparable in general. No significant differences were found in blood pressure or heart rate before and after treatment between the two groups (P>0.05). The incidence of hypotension events in CRRT+HP group was significantly lower than that in HD+HP group (P<0.05), and the effective rate of cardiac function improvement in CRRT+HP group was significantly higher than that in HD+HP group (P<0.05). After treatment, the blood urea nitrogen, creatinine, parathyroid hormone, β2-microglobulin, phosphorus, C-reactive protein and brain natriuretic peptide in the two groups were significantly decreased than those before treatment (P<0.05). Parathyroid hormone, β2-microglobulin, C-reactive protein and brain natriuretic peptide were significantly decreased in CRRT+HP group as compared with those in HD+HP group (P<0.05). The remission rate of uremic encephalopathy in CRRT+HP group was significantly higher than that in HD+HP group (P<0.05).
Conclusions
As compared with HD+HP pattern, CRRT+HP pattern is more stable in the hemodynamics, and more effective in the improvement of heart failure and the clearance of inflammatory mediators, middle molecular and macromolecular substances associated with uremic encephalopathy. CRRT+HP pattern is suitable for the treatment of patients with diabetes and uremic encephalopathy.
The formation of an arteriovenous fistual for dialysis by routine interrupted sutures anastomosing the vein and artery is difficult to perform and time-consuming. A new method, telescopic adhesive anastomosis was studied and applied in 10 hemodialysis patients, who were in need of an arteriovenous fistula. The external diameter of the vessels anastomosed was 2.40 +/- 0.20 mm (radial artery) or 2.40 +/- 0.35 mm (cephalic vein). After thorough debridement of the vascular ends, the arterial end was put in the venous lumen. In order to fix the telescopic vessels, two stitches were applied 180 degrees apart from each other and tied. Each stitch was inserted from vein (penetrating the whole wall) to artery (just through the adventitia and partial thickness of the media vasorum). The distance from the stitch to the edge of the vein was 0.5 mm, and that of the artery was approximated to the external diameter of the vessle. The medical adhesive was then applied for sealing the anastomotic adventitia. Ten seconds were given for the solidification of the adhesive. The patients were followed up for 8 months. The patency rate was 100%, and the rate of blood flow was more than 300 ml/min (measured by ultrasonography). It was shown that this method could be managed easily and quickly, and the so-formed fistula would fulfill the need of hemodialysis.
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.
ObjectiveTo study the differences in body composition between maintenance hemodialysis (MHD) patients with reduced muscle mass and the ones with normal muscle mass by bioelectrical impedance analysis, and explore the influencing factors.MethodsA total of 122 patients undergoing MHD in the hemodialysis center of a general hospital between September 2018 and May 2019 were selected as the research subjects. According to the relative skeletal muscle mass index, they were divided into the muscle loss group and the normal muscle mass group. Their general conditions, post-dialysis body composition, and serum albumin were collected to analyze the differences between the two groups, and a multiple stepwise logistic regression analysis was carried out.ResultsAmong the included subjects, 53 patients had normal muscle mass and 69 patients had muscle mass loss. The post-dialysis body weight, muscle-related indexes, intracellular water, extracellular water (ECW), total body water (TBW), protein, minerals, body cell mass, bone mineral content, body mass index, arm circumference, and arm muscle circumference in the normal muscle mass group were higher than those in the muscle loss group (P<0.05); the percentage of ECW/TBW in the normal muscle mass group was lower than that in the muscle loss group (P<0.05). The multiple stepwise logistic regression analysis showed that the post-dialysis weight [odds ratio (OR)=0.679, 95% confidence interval (CI) (0.535, 0.862), P=0.001] was a protective factor from losing muscle in MHD patients, and the high ECW/TBW [OR=6.926, 95%CI (1.014, 47.280), P=0.048], low body cell mass [OR=57.707, 95%CI (6.927, 480.761), P<0.001], low bone mineral content [OR=9.743, 95%CI (1.220, 77.831, P=0.032], and arm circumference [OR=2.183, 95%CI (1.004, 4.749), P=0.049] were risk factors for muscle loss in MHD patients.ConclusionsMHD patients have a high incidence of muscle loss. It is necessary to monitor the changes of their body composition, especially those who with low post-dialysis body weight, lack of bone minerals and body cells, excessive ECW/TBW, and increased arm circumference after hemodialysis. Both nutritional interventions and exercise interventions should be performed timely and routinely to prevent the occurrence of sarcopenia.
ObjectiveTo investigate the prevalence of gallbladder stone in dialysis patients, determine whether it is higher than that in the general population, find out the difference of prevalence between hemodialysis and peritoneal dialysis patients, and analyzes the possible causes.
MethodsWe analyzed the prevalence of gallbladder stone in 358 dialysis patients (126 cases of hemodialysis and 232 cases of peritoneal dialysis) followed up in our hospital from January 2009 to October 2012. And we compared it with 376 patients diagnosed with chronic kidney disease stage 5 (CKD5) and the general population.
ResultsThe prevalence of gallbladder stone in dialysis patients followed up in our hospital was 23.5%, which was higher than CKD5 patients (P=0.002). The prevalence was significantly greater in dialysis patients than that in the general population (P<0.000 5). In the dialysis patients who were younger than sixty years old, the prevalence of gallbladder stone in peritoneal dialysis patients was obviously higher than that in the hemodialysis patients (P<0.05). The albumin level was significantly lower in peritoneal dialysis patients than in the hemodialysis patients. At the same time, cholesterol, low density lipoprotein, and the ratio of low density lipoprotein to high density lipoprotein were much higher with statistical significance. Logistic regression analysis showed that increasing age (OR=2.581, P=0.001), female (OR=2.554, P=0.000), the primary disease (diabetes mellitus) (OR=1.947, P=0.044) and dialysis period (OR=1.000, P=0.006) were risk factors for gallbladder stone in dialysis patients.
ConclusionThe prevalence of gallbladder stone in dialysis patients is higher than that in the general population. Peritoneal dialysis patients have more risk factors to get gallbladder stone than hemodialysis patients. Risk factors for gallbladder stone in dialysis patients are increasing age, female, primary disease (diabetes mellitus), dyslipidemia, hypoalbuminemia, long dialysis period and so on.
Objective
To evaluate the effect of Fogarty balloon catheter embolectomy on arteriovenous graft thrombosis in hemodialysis patients.
Methods
We retrospectively analyzed the clinical data of 11 patients who underwent maintaining hemodialysis and arteriovenous graft thrombosis through Fogarty balloon catheter embolectomy between March 2010 and November 2014. The thrombosed graft was incised, and a 4 or 6 French catheter was placed in the venous and arterial limbs of the graft respectively. The Fogarty balloon was passed beyond the thrombus and pulled out after saline was infused into the balloon, and the thrombus was taken out. The procedure was considered unsuccessful if the blood flow was not re-established or if the graft re-thrombosed within hours.
Results
The treatment was successfully performed in all the patients. Of the 11 patients, 3 received balloon dilation due to stenosis of venous anastomosis, and 2 received angioplasty due to underlying arterial anastomosis lesion. After corresponding measures were taken, the thrombus of all the 11 patients were taken out, and blood flow was recovered. Two to seven days after surgery, low molecular weight heparin was used for anti-coagulation. The blood flow of all arteriovenous grafts reached over 250 mL/min. All the patients were followed up for 4 to 30 months. During the follow-up, the arteriovenous graft remained functional in 5 patients; 4 patients had re-thrombosis on day 2, 3, 25, and 71 after surgery respectively; one changed to undergo peritoneal dialysis due to rupture and infection of the graft, and one patient was transferred to another hospital in another area and was not followed up any longer. The therapy was successful in 81.8% of this group of patients.
Conclusion
Fogarty balloon catheter embolectomy is effective in restoring patency of thrombosed arteriovenous graft in hemodialysis patients, and more studies are needed.
