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.
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.
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).
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 assess the efficacy and safety of Lanthanum Carbonate for hyperparathyroidism in dialysis patients. Methods We searched MEDLINE (1996 to April 2006); EMBASE (1996 to April 2006); Cochrane Central Register of Controlled Trials (Issue 1, 2006); CBM disc; VIP and CNKI. We also checked the references of relevant studies. Randomized controlled trials (RCTs) comparing Lanthanum Carbonate with placebo and standard therapy were eligible for inclusion. Quality assessment and data extraction were done by two reviewers independently. Meta-analysis was conducted using The Cochrane Collaboration’s RevMan 4.2.8. Results Six RCTs were included. Lanthanum Carbonate was found to be more effective than placebo in treating hyperparathyroidism of dialysis patients (OR 4.74, 95%CI 2.66 to 8.45; Plt;0.0001) and the incidence of all drug-related adverse events was similar between Lanthanum Carbonate and placebo-treated group (OR 1.23, 95%CI 0.74 to 2.04; P=0.42). The meta-analysis also showed that the efficacy of treating hyperparathyroidism of dialysis patients was similar between Lanthanum Carbonate and conventional phosphate binders (OR 0.97, 95%CI 0.74 to 1.27; P=0.81) and the incidence of all drug-related adverse events was also similar (OR 1.29, 95%CI 0.62 to 2.47; P=0.49). However, serum calcium level was lower in the Lanthanum Carbonate group than in the conventional phosphate binders group. Conclusion Lanthanum Carbonate is effective and well-tolerated in treating hyperparathyroidism of dialysis patients with end-stage renal disease(ESRD). The incidence of hypercalcemia induced by Lanthanum Carbonate is significantly lower than that of the conventional phosphate binders. However, more large-scale, randomized, double-blinded trials are required to investigate the long-term safety and efficacy of Lanthanum Carbonate.
Objective To investigate and analyze the employment status and related influencing factors of maintenance hemodialysis (MHD) patients. Methods MHD patients from four hemodialysis centers in Beijing between January 2020 and January 2021 were selected. The baseline data and clinical data of patients with long dialysis interval were collected. An anxiety and depression survey was conducted on the patient. Results A total of 108 MHD patients were included. Among them, 41 patients were working and 67 patients were not working. Among the 41 patients at work, there were 3 workers, 1 farmer, 14 company employees, 6 public institution employees, 11 self-employed, 5 freelancer and 1 other. Among the 67 patients who did not work, 8 patients had the ability to work but did not work. Body mass index was an independent influencing factor for employment in MHD patients [odds ratio=1.135, 95% confidence interval (1.017, 1.266), P=0.024]. Conclusion The nutritional status of MHD patients should be taken seriously to improve their employment rate.
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.
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.
