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.
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.
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.
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 systematically review the pharmacoeconomics of hemodialysis and peritoneal dialysis in patients with end-stage renal disease. MethodsCRD, NICE, CADTH, HITAP, NECA, IWIQG, ISPOR, PubMed, EMbase, CNKI, and WanFang Data databases were electronically searched to collect pharmacoeconomic studies on the hemodialysis and peritoneal dialysis in the treatment of end-stage renal disease from inception to December 2020. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, the conclusions of research models, pharmacoeconomic evaluation results, and sensitivity analysis were summarized. ResultsA total of 15 pharmacoeconomic studies were included, among which 9 studies used the Markov state transition model, and 6 were observational studies. From the perspective of health outcomes, peritoneal dialysis had cost-effectiveness advantages over hemodialysis in the treatment of end-stage renal disease under the condition of a clear threshold. ConclusionsCurrent evidence shows that compared with hemodialysis, peritoneal dialysis has certain cost-effectiveness advantages in the treatment of end-stage renal disease. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
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.
ObjectivesTo systematically review the influence for catheter mechanical dysfunction of different peritoneal dialysis catheterization methods.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were searched to collect randomized controlled trials (RCTs) and cohort studies on comparisons of different peritoneal dialysis catheterization from inception to March 31st, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Network meta-analysis was then performed by using ADDIS 1.16.6 software.ResultsA total of 33 studies (9 RCTs and 24 cohort studies) involving 3 301 patients were included. Network meta-analysis showed that the incidence of catheter mechanical dysfunctionwas the least and had statistically significant difference compared with that in percutaneous catheterization (OR=3.60; 95%CI, 1.64 and 15.38) and open surgery catheterization (OR=5.86; 95%CI, 2.68 and 14.53). Percutaneous catheterization was superior to open surgery catheterization, but there was no significant difference.ConclusionsLaparoscopic catheterization may be the best technique for catheter insertion in peritoneal dialysis considering catheter dysfunction. Each technology has its own advantages. Choice of insertion method should be based on the characteristics of both the patient and the insertion techniques.
ObjectiveTo compare the incidences of peritoneal dialysis (PD)-associated peritonitis among HIV and non-HIV patients, and to analyze the risk factors of PD-associated peritonitis. MethodsEnd-stage renal disease patients with HIV infection who newly started PD in West China Hospital of Sichuan University from 2012 to 2020 were retrospectively included, and non-HIV PD patients in the same period were included as controls at a ratio of 1 to 4. The risk factors of PD-associated peritonitis were analyzed by univariate analysis and multivariate logistic analysis. Kaplan-Meier survival analysis and COX regression analysis were used to compare the peritonitis-free survival between HIV group and non-HIV group. ResultsA total of 60 PD patients were included. The average follow-up time was 31.2±21.3 months. Peritonitis occurred in 7 HIV patients (58.33%) and 8 non-HIV patients (16.67%). Logistic regression analysis showed that HIV infection (P=0.018) and high platelet (>150×109/L) (P=0.032) were independent risk factors for PD-associated peritonitis. The incidence of PD-associated peritonitis in HIV patients significantly increased (HR=10.944, 95%CI 1.503 to 79.707). Kaplan-Meier survival analysis showed that the 5-year peritonitis-free survival of non-HIV group was significantly higher than that of HIV group (75.7% vs. 31.1%) (P=0.003). Multivariate COX survival analysis showed that the 5-year accumulative risk of peritonitis in HIV PD patients was 5.896 times (95%CI 1.508 to 23.043, P=0.01) higher than that of the non-HIV PD patients. ConclusionHIV infection is an independent risk factor for PD-associated peritonitis.
Objective To investigate the change of pathogenic distribution and drug resistance in peritoneal dialysis associated peritonitis (PDAP). Methods The clinical data of all the patients undergoing continuous ambulatory peritoneal dialysis and suffered from PDAP between January and December in 2014 was retrospectively collected, and the pathogens, drug resistance, outcomes and underlying causes were analyzed. Results A total of 64 patients had 72 cases of PDAP. Only 36 strains (50.0%) had positive culture results, among which 24 strains (66.7%) were Gram-positive bacteria strains, 7 strains (19.4%) were Gram-negative bacteria strains, and 5 strains (13.9%) were fungi. For Gram-positive bacteria strains, the resistance rates to vancomycin, linezolid and rifampicin were all 0%; the resistance rate to levofloxacin, gentamycin and cefazolin was 14.3%, 26.3% and 50.0%, respectively. For Gram-negative bacteria strains, the resistance rates to amikacin and imipenem were both 0%; the resistant rate to gentamycin, ceftazidime, levofloxacin and ampicillin was 28.6%, 28.6%, 42.9% and 100.0%, respectively. Conclusions The pathogenic spectrum and drug resistance in PDAP have been markedly changed. Selection of antibiotics should be chosen according to the characteristic of the pathogenic spectrum and drug resistance of each center. Great effort is still needed to improve the culture positive rate of the effluent dialysate and to improve the recovery rate of peritonitis.
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.
