ABSTRACT

Objective:To explore the puncture management in hemodialysis patients with difficult new arteriovenous fistula based on the finest evidence-based best practice evidence and evaluate the clinical effects.Methods:A team was formed, according to theoretical framework basing on the evidence of continuous quality improvement model, the best evidence-based interventions were obtained by adopting evidence-based practice. Formulated review indicators, evaluated obstacles and promoting factors in the process of practice, and took corresponding action strategies. From February 2020 to June 2020, 30 patients admitted to the dialysis center of Sir Run Run Shaw Hospital of Zhejiang University were recruited in the baseline review group by convenience sampling method. From September 2020 to January 2021, 30 patients from September 2020 to January 2021 were recruited in the after-effect evaluation group. The baseline review group adopted the original difficult new arteriovenous fistula puncture management scheme, and the after-effect evaluation group adopted the difficult autologous new internal fistula puncture management scheme based on the best evidence. The success rate of one puncture of fistula, the incidence rate of hematoma during puncture and dialysis, the incidence rate of discontinuation of treatment and the compliance with examination indexes were compared in the patients before and after applying for the evidences.Results:Compared with the baseline review group, the success rate of one-time puncture of internal fistula in the aftereffect evaluation group increased from 36.7% (11/30) to 73.3% (22/30), the incidence rate of hematoma during puncture and dialysis were decreased from 33.3%(10/30) to 6.67%(2/30) and 40%(12/30) to 0, the incidence rate of discontinuation of treatment were decreased from 40%(12/30) to3.33% (1/30), the difference was statistically significant ( χ2 values were 6.67-11.88, P<0.05). The implementation rate of review indexes in the aftereffect evaluation group was higher than that in the baseline review group, and the difference was statistically significant ( P<0.05). Conclusions:Evidence-based practice can improve the success rate of difficult new arteriovenous fistula, and reduce the incidence of arteriovenous fistula hematoma, reduce treatment interruption, and better maintain the lifeline of patients.

ABSTRACT

Objective To preliminarily investigate the methods,safety and short to medium-term effectiveness of the interventional ultrasound applying in the hybrid procedure to treat the thrombosis of arteriovenous graft(AVG).Methods Twenty patients with the thrombosis of AVG,who received the hybrid procedure defined as Fogarty catheter thrombectomy and percutaneous transluminal angioplasty (PTA) guided by the ultrasonography,were retrospectively investigated. The display effects of the ultrasonography were observed.The technical and clinical success rates were evaluated.All the cases were followed up every 3 months for at least 1 year to evaluate the post-interventional assisted primary patency and the post-interventional secondary patency.Results All the processes were clearly displayed and well guided by the interventional ultrasound during the procedure.The technical and the clinical success rates were both 100%.No major complications were recorded.The post-intervention assisted primary patency rate was 100%,92.9%,85.7%,71 .4% at 3,6,9,12 months,respectively.The post-intervention secondary patency was 100%,100%,89.5%,89.5% at the correspondent months.Conclusions This pilot research shows the hybrid procedure guided by the interventional ultrasound to treat the thrombosis of AVG has high success rate and satisfied patency in short to medium-term.The interventional ultrasound is an effective, safe and convenient guiding method to the hybrid procedure,and has the value for clinical application.

ABSTRACT

Objective To design and investigate the clinical effects of parallel double venous pots hemodialysis tubing set in patients with heparin-free hemodialysis.Methods Totally 120 patients who received hemodialysis therapy in our hospital from May,2014 to June,2016 were randomly divided into the experimental group (n=60) and the control group(n=60) via random number table.The experimental group received self-designed parallel double venous pots dialysis tubing set,while the control group received the normal dialysis tubing set.The number of preventive replacement of dialyzer and tubing set during heparin-free dialysis,the number of discarded tubing set due to coagulation and the time frame for the first tubing set were recoded from two groups.Results There were statistically significant differences in the number of discarded tubing set due to coagulation and the time frame for the first tubing between two groups(P<0.05).Conclusion Parallel double venous pots dialysis tubing set can reduce the number of discarded tubing set due to coagulation,prolong the time frame for the first tubing.

ABSTRACT

Objective To elucidate the role of renal progenitor-like tubular cells in the repair process after acute tubular necrosis(ATN)induced by ischemia. Methods Rat ATN was developed by clamping left kidney artery for 60 minutes,and bromodeoxyuridine(BrdU),a cell division and proliferation marker,was administrated one hour before rats were sacrificed.Kidneys were isolated at 1,3,5,7,14,21,28 days after injury.The proliferative and apoptotic cells were determined by immunostaining using anti-BrdU,Pax2(an embryonic renal marker),vimentin(an immature mesenchymal cell marker),and activated caspase-3(a cell apoptosis marker). Results Cell death was found in tubules at day 1 after ischemia and reperfusion injury.BrdU-positive cells were dramatically increased and reached peak at day 3 after injury.In addition,the number of BrdU positive cells in the contralateral kidney was significantly increased compared to sham operated group.Double immunostaining showed that BrdU-positive cells co-expressed Pax2 or vimentin,but not activated caspase-3. Conclusions Renal progenitor-like tubular cells may play a predominant role in repair process following ATN in rats.They may dedifferentiate,proliferate,and then redifferentiate into mature tubular cells.Growth factors may regulate the repair process.
