Objective To investigate the efficacy and safety of polyethersulfone highflux dialyzer for uremic patients. Methods Forty eligible uremic patients were randomized into two groups, i.e. polyethersulfone (PES) group and polysulfone(PSF) group, according to a random number table. The PES group received hemodialysis for 4 hours with polyethersulfone highflux dialyzer (Chengdu OCI Medical Device Co., Ltd), and the PSF group with polysulfone highflux dialyzers (Fresenius Polysulfones, Fresenius Medical Care, Bad Homburg, Germany). Changes in serum creatinine, urea, β2-microglobulin, hemoglobin and albumin levels were determined for efficacy and safety evaluation. Results All the 40 patients completed the trial. The serum creatinine, urea, β2-microglobulin levels of all the patients in the two groups decreased (gt;30%) after the hemodialysis with different highflux dialyzers, and no significant difference was observed between the two groups (Pgt;0.05). Changes in solute clearance index (KT/V) value, hemoglobin and albumin levels were also comparable between the two groups (Pgt;0.05). Conclusions The efficacy and safety of the PES hollow fiber membrane hemodialyzer is equivalent to that of the PSF hemodialyzer in hemodialysis for uremic patients.
目的 总结妊娠合并尿毒症患者血液透析的护理措施。 方法 回顾性分析2001年3月－2012年6月收治的15例妊娠合并尿毒症患者行血液透析的临床资料。患者年龄平均30.5岁；2例为早期妊娠，孕13周，其中1例伴有尿毒症急性发作，其余均为中晚期妊娠，孕24+周，均血清肌酐＞445 μmol/L（5 mg/dL），尿氮素＞20 mmol/L。15例患者入院后即刻行血液透析治疗，治疗过程中进行必要的心理干预，在透析前、中、后护理中，密切观察患者心理状况，孕妇各项生命体征及胎儿胎心胎动等，择期终止妊娠。 结果 9例经维持性血液透析治疗后，病情稳定，顺利产下胎儿；另外3例患者经血液透析治疗后病情稳定，其中1例产下一死婴，另2例行人工钳取术终止妊娠；还有3例患者由于经济条件限制而中途退出治疗。 结论 适时的干预和加强妊娠合并尿毒症患者血液透析的护理，可取得很好的治疗效果，有可能改变妊娠的结果。
ObjectiveTo evaluate the value of computed tomography examination in the clinical diagnosis guidance and therapeutic effect assessment for patients with uremic pneumonia. MethodsWe reviewed the clinical situation and pathogenesis turnover of 64 cases of uremic pneumonia from February 2011 to January 2013,and analyzed the correlation between image modification and treatment effectiveness. ResultsSixty-four cases of uremic pneumonia had different image manifestations in each phase of the disease course,including 27 cases of pulmonary venous pleonaemia,51 of lung interstitial edema,8 of pulmonary alveoli effusion,and 15 of pulmonary interstitial fibrosis.Dropsy of serous cavity and the heart shape could be viewed by CT scanning.CT rechecking was carried out after hemodialysis and symptom-targeted treatment.The results showed that CT results of 27 cases of pulmonary venous pleonaemia,51 cases of edema in the interstitial tissue and 41 cases of pleural effusion changed significantly after treatment (P<0.001);the image manifestations of 8 cases of pulmonary alveoli edema also changed significantly (P<0.05);the CT result of 15 cases of pulmonary interstitial fibrosis had no change;six cases among the fourteen cases of pericardial effusion were not absorbed by treatment (P>0.05). ConclusionThe diagnosis of uremic pneumonia mainly depends on imaging results.CT scanning plays an important role on the determination of clinical stage,the choice of therapeutic method,and evaluation of curative effect for uremic pneumonia.
ObjectiveTo explore the value of ultrasound evaluation and marking before arteriovenous internal fistula in end-stage renal disease hemodialysis patients. MethodsTwenty-five uremia end-stage patients were admitted into our nephrology department from January 2012 to July 2012. All of the patients had encountered several times of fistula failure or had difficulty in establishing the forearm arteriovenous fistula. We focused on observing the brachial artery, radial artery, cephalic vein, the basilica vein and great saphenous vein. We measured the diameter of the vessels and marked the trend of arteries and veins in the body surface under the ultrasonic navigation. Our goal was to look for appropriate bypass vessels in the elbow and the upper arm. ResultsFourteen patients had endured several times of fistula failure. Among the 14 patients, 9 patients completed the surgery of reengineering fistula and autogenous great saphenous vein transplantation, 2 accepted artificial vascular transplantation, 1 completed the removal of blood clots in the left upper limb artificial blood vessels and arteriovenous internal fistula molding, and 2 gave up surgery. Eleven patients could not complete the arteriovenous fistula operation for the fine forearm superficial vein. Of them, 2 patients accepted artificial vascular operation, 6 underwent autogenous great saphenous vein transplantation, 1 with slender radial artery in diameter completed higher position fistula between the brachial artery and median cubital vein, and 2 gave up surgery. ConclusionArteriovenous internal fistula preoperative ultrasound assessment and marking have very important value in improving the success rate of operation in end-stage uremia patients.
Objective To investigate the change of cardiac structure and function in patients with uremia before and after peritoneal dialysis (PD). Methods Eighty three standard continuous ambulatory peritoneal dialysis (CAPD) patients treated between October 2009 and October 2014 were selected in this study. According to the ultrasound cardiogram before and 6 months after the PD, we analyzed the influence of age, diabetes mellitus, dialysis interval, hemoglobin, serum albumin, serum creatinine, serum calcium and phosphate and parathyroid hormone (PTH) on the cardiac structure and function. Results Hemoglobin increased significantly after PD (P <0.01), while albumin and PTH decreased significantly (P <0.01). The changes in creatinine, triglyceride and cholesterol were not statistically significant (P > 0.05). For CAPD patients, cardiac systolic function did no t obviously change before and after dialysis, while the diastolic function improved obviously after dialysis. Conclusion PD may improve cardiac diastolic function of CAPD patients.
目的探讨为维持性血液透析患者行肘部动静脉内瘘的手术方法及技巧。 方法回顾性分析我院2009年8月至2012年8月期间行肘部动静脉内瘘68例患者的临床资料。 结果68例患者手术均成功。所有患者术后血流量都能满足血液透析需要，无感染、皮下血肿等并发症。随访至今，未发现血管内血栓形成、造瘘口狭窄等。 结论对于腕部自体动静脉不能行造瘘术时，肘部动静脉内瘘为血液透析患者提供了一条新的血管通路。
ObjectiveTo investigate the effectiveness of a suture bridge technique for quadriceps tendon rupture repair in uraemic patients. MethodsBetween March 2010 and September 2012, 10 uraemic patients (14 sides) with quadriceps tendon rupture were treated with the suture bridge technique. Of them, 8 were male and 2 were female, aged from 30 to 62 years (mean, 54.2 years). The duration of uremia was 3-11 years (mean, 5.5 years);the duration of quadriceps tendon rupture was 5 days to 2 months (median, 12 days). Six cases had a trauma history, and one case had diabetes. The left side was involved in 2 cases, the right side in 4 cases, and both sides in 4 cases. The active range of motion (ROM) of the knees was (115.0±8.3)°in flexion, and (72.5±21.2)°in extension. Lysholm score was 19.5±16.3. X-ray films showed downward shifting of patella. MRI revealed discontinuity between distal quadriceps tendon and upper pole of patella. ResultsThe operation time was 30-50 minutes (mean, 40.3 minutes). Primary healing of incision was obtained in all patients without complications. All patients were followed up 12-25 months (mean, 16.3 months). There was no re-rupture of quadriceps tendon or loosening of internal fixation during follow-up. At last follow-up, the active ROM of the knees was (121.0±7.9)°in flexion, showing no significant difference when compared with preoperative one (t=-2.075, P=0.058); the active ROM was (8.2±6.1)°in extension, showing significant difference when compared with preoperative one (t=11.702, P=0.000). Lysholm score was 84.6±12.4, showing significant difference when compared with preoperative score (t=-16.226, P=0.000). According to the American Knee Society score (KSS), the results were excellent in 4 sides, good in 9 sides, and fair in 1 side, and the total excellent and good rate was 92.9%. At last follow-up, the active ROM of the knee, Lysholm score, and KSS score were significantly better in young patients (<45 years) than in elder patients (≥45 years), and in patients receiving early operation (<2 weeks) than in patients receiving late operation (≥2 weeks) (P<0.05). ConclusionFor fewer traumas and early functional exercise after operation, the suture bridge technique benefits functional restoration of knee joint in uraemic patients. Operation chance and age seem to be important factors to the results. Early operation should be considered when quadriceps tendon ruptured.
