Objective To assess the possible causes of acute pancreatitis (AP) in long term peritoneal dialysis (PD) and hemodialysis (HD) patients, and to discuss the diagnosis and treatment of AP in this kind of patients. Methods The clinical data of 9 cases of AP in PD and HD patients who were admitted in the hospital during January 1993 and January 2000 were analysed retrospectively. Results The serum levels of amylase of all the 9 cases were over three and a half times of upper limit value of healthy subjects. B mode ultrasound and CT scan examinations were useful for diagnosis of AP. Eight patients recovered very well with conservative treatment, while one patient who was diagnosed as acute severe pancreatitis and complicated with shock died. Conclusion Long term PD and HD patients are predisposing to develop AP. Diagnosis of AP in these patients primarily depends on the detection of serum amylase. Dialysis treatment is indispensable for cure of AP.
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 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.
ObjectiveTo reduce the incidence of peritoneal dialysis (PD) catheter complications through a continuous quality improvement (CQI) process. MethodsTwenty-nine patients with catheters inserted (from January 2011 to March 2011) before CQI, and another 41 patients with catheters inserted (between April 2011 and January 2012) after CQI were observed and analyzed. The possible causes of complications of catheter were summarized, and then on the basis of that, a PDCA four-step (plan-do-check-act) method was designed with a view to reducing the incidence of postoperative complications. ResultsPD catheter dysfunction decreased from 6.90% to 2.44%. The incidence of leakage decreased from 44.83% to 9.76%. ConclusionCQI is a useful method to reduce the incidence of postoperative complications of PD catheter in peritoneal dialysis.
ObjectiveTo observe whether proteinuria is relate to the decline of residual renal function (RRF) in peritoneal dialysis (PD) patients. MethodsThis is a prospective cohort study including 45 PD patients (underwent PD between January 2011 and January 2013) with a 12-month follow-up. All the patients were divided into 2 groups with respect to the initial proteinuria level: massive proteinuria group A (n=20) and non-massive proteinuria group B (n=25) at baseline. We established regression models to do univariate analysis and multivariate analysis of the relationship between the decline of RRF≥50% of baseline and the indices of age, sex, PD-associated peritonitis, baseliner residual glomerular filtration rate (rGFR), initial proteinuria, and use of ACEI/ARB. ResultsThe primary outcome (RRF>50% of baseline) at 12 months was 65% in group A, and 80% in group B (P<0.05). Based both on the results of univariate and multivariate Cox regression analysis, non-massive proteinuria and higher rGFR at baseline were factors to protect RRF from decline (P<0.05). ConclusionThe study demonstrates that massive proteinuria and lower rGFR at baseline may be associated with a rapid decline of RRF in PD patients. Treatment aimed at reducing albuminuria may lead to protect RRF and improve life quality of patients.
ObjectiveTo explore the practice effect of the combination management of tertiary hospital and community hospital for home peritoneal dialysis patients. MethodsA total of 50 patients of end-stage renal disease from December 2012 to May 2013 were involved in this study, including 26 males, and 24 females with the average age of 47.1±13.9. The patients were randomly divided into hospital group (30 patients) and combination group (20 patients). For the patients in the hospital group, the specialists take care of them with regular outpatient service and follow-up; for the patients in the combination group, they were taken care by doctors from both tertiary hospital and community hospital, while the community general practitioners were trained by the tertiary hospital regularly with peritoneal dialysis basic treatment and standardization management and communication. All the patients were managed for 9 months. ResultsAt the end of the observation,the dialysis adequacy success rate, hemoglobin, blood potassium, phosphorus, calcium, albumin, CO2CP, blood pressure success rate, the incidence of peritonitis, and average monthly medical treatment expense between the two groups were not statistically different (P>0.05); the difference in cost of transportation was statistically significant (P<0.05). ConclusionThe standardization manage of combination of tertiary hospital and community for patients with home peritoneal dialysis may reduces the patients' expense in transportation, and improve the community general practitioners' level of basic knowledge and indication of peritoneal dialysis.
ObjectiveTo investigate whether continuous quality improvement (CQI) measures can reduce the episodes of peritonitis. MethodsWe analyzed the data of 114 cases of peritoneal dialysis related peritonitis from January to December 2011 before applying CQI measures and 72 cases from January and December 2012 after applying CQI measures in West China Hospital. Then we studied the episodes, cause and pathogenic bacteria species of peritonitis in peritoneal dialysis patients. We implemented the process of reducing the episodes of peritonitis by applying PDCA four-step design: plan-do-check-act. ResultsThe episodes of peritonitis were reduced from per 60.8 patient-months (0.197/patient-years) to per 66.6 patient-months (0.180/patient-years) after applying CQI measures. The positive rate of pathogenic bacteria culture was both 50.0% before and after applying CQI measures, in which 66.7% were gram-positive cocci. The curing rate of peritonitis was increased from 57 case/times (76.3%) to 87 case/times (79.2%). Switching to hemodialysis rate was reduced from 17 cases/times (14.9%) to 10 cases/times (13.9%). Death cases was reduced from 9 cases/times (7.9%) to 5 cases/times (6.9%). ConclusionThese results show that the incidence of peritoneal dialysis related peritonitis decreases and the curing rate increases through CQI measures.
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.
ObjectiveTo investigate the influence of evidence-based nursing intervention on the treatment effect and quality of life in patients with peritoneal dialysis. MethodSixty-four patients who underwent peritoneal dialysis between January 2013 and December 2014 in our hospital were randomly divided into control group (n=32) and intervention group (n=32) . The control group received routine nursing and the intervention group received evidencebased nursing intervention. Urea clearance index (KT/V), serum albumin and hemoglobin levels were detected for both groups of patients before and after nursing intervention. Generic Quality of Life Inventory (GQOLI)-74 scale was used to assess patients' quality of life. ResultsAfter nursing intervention, KT/V, serum albumin and hemoglobin levels in the intervention group were significantly higher than those in the control group (P<0.05) . The scores of such items as physical function, psychological function, social function and overall evaluation in the GQOLI-74 scale in the intervention group were significantly higher than those in the control group (P<0.05) . ConclusionsEvidence-based nursing intervention can effectively improve the treatment effect and quality of life in patients with peritoneal dialysis, which is worthy of clinical popularization and application.
Objective To investigate the efficacy and safety of ultrasound-guided TAP block for the anesthesia in peritoneal dialysis (PD) catheter implantation. Methods Patients with end-stage renal disease who intended to receive PD catheter implantation in the West China Hospital of Sichuan University were enrolled from April 2015 to February 2016. Those who met the inclusion criteria were randomly divided into two groups: the local filtration anesthesia (LF) group and the TAP group. The two groups got the ultrasound guided TAP block (The LF group got a shame TAP block by making the skin wheal and just inserting the needle into the TAP with the guidance of ultrasound), then the LF group received local filtration anesthesia twenty minutes later, with the TAP group had sham LF anesthesia by injection of saline at the incision subcutaneously. The anesthetist generated the random allocation sequence and performed all TAP/sham blocks according to the allocation of each patient. The patients, investigators were all blind to the allocation. The follow-up time was 3 months. The primary outcomes were the rate of alteration to general anesthesia and the VAS score during and after the surgery. The dosages of sufentanil for analgesia during and after were recorded. The satisfaction to the effect anesthesia by the operation doctors, PD catheter related complications and adverse events related to TAP block or anesthetic agent were also recorded. Statistic analysis was conducted using SPSS 19.0 software. Results A total of 36 patients were included, 12 cases in the LF group and 24 cases in the TAP group. The rate of alteration to general anesthesia in the TAP group was 4.12% and was significantly lower than that in the LF group (33.3%) (P=0.034). The VAS scores at the time points of incision of skin, division of subcutaneous tissue and anterior rectus sheath, opening the peritoneum, insertion of PDC, suture of skin, 2 hours and 24 hours after operation were significantly lower in the TAP group compared to the LF group (P values=0.001, 0.037, 0.000, 0.001, 0.029, 0.035, and 0.000, respectively). The TAP group consumed less sufentanil during the operation and showed a higher satisfaction of the operation doctors. There were no significant differences in the PD catheter related complications and adverse events between the two groups. Conclusion The ultrasound-guided TAP block can be an effective and safe anesthesia method for PD catheter implantation. Because of the limitation of small sample size of this study, a multiple center study with larger sample size is suggested.
