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.
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.
ObjectivesTo explore the association between initial peritoneal transport characteristics and patient survival, and to evaluate the risk factors for mortality of continuous ambulatory peritoneal dialysis (CAPD) patients.MethodsBetween January 2011 and December 2016, the patients diagnosed with end stage renal disease commencing CAPD in West China Hospital were enrolled. According to the value of dialysate to plasma ratio for creatinine at 4 hour [D/P Cr (4 h)], CAPD patients were divided into two groups: the lower transport group [D/P Cr (4 h)<0.65] and the higher transport group [D/P Cr (4 h)≥0.65]. The survival of these two groups of peritoneal dialysis patients were plotted using survival analysis. CAPD patient outcomes were analyzed using multivariable Cox proportional hazards regression models.ResultsCompared with the lower transporter (n=246), higher transporter (n=345) were older, and with more peritoneal protein loss, lower level of serum albumin, lower level of hemoglobin, and less ultrafiltration (P<0.001). Higher transport group had lower survival rate compared to those in the lower transport group (P=0.001). The 1-, 3- and 5-year patient survival rates were 97.0%, 83.2%, and 71.7% in the higher transport group, and 98.7%, 93.9%, and 86.1% in the lower transport group, respectively. There was a positive relationship between D/P Cr (4 h) and serum peritoneal protein loss (P<0.001). D/P Cr (4 h) was inversely related to serum albumin (P<0.001). Cox regression analysis demonstrated that lower albumin [hazard ratio (HR)=0.921, 95% CI (0.885, 0.958), P<0.001], presence of cardiovascular disease [HR=1.996, 95% CI (1.256, 3.173), P=0.003], elder age [HR=1.049, 95% CI (1.033, 1.065), P<0.001], lower hemoglobin [HR=0.988, 95% CI (0.976, 1.000), P=0.044] and lower urea clearance index (KT/V)[HR=0.680, 95%CI (0.465, 0.994), P=0.046] could independently predicted mortality with significance in CAPD patients. But higher peritoneal transport was not a risk factor for mortality [HR=1.388, 95%CI (0.829, 2.322), P=0.212] in either model including serum albumin.ConclusionsFor CAPD patients, initial higher transporter had a higher mortality than lower transporter. However, initial higher peritoneal transport was not a risk factor for mortality independent of serum albumin in CAPD patients. Relationship between D/P Cr (4 h) and serum peritoneal protein loss and serum albumin suggests that higher peritoneal transport characteristics might worsen prognosis by lowering serum albumin level at initiation of peritoneal dialysis.
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 investigate the clinical characteristics, treatment and outcomes of patients with Acinetobacter baumannii peritoneal dialysis-related peritonitis.MethodsWe retrospectively analyzed the clinical data of patients with Acinetobacter baumannii peritoneal dialysis-related peritonitis in the First Affiliated Hospital of Airforce Military University from January 2011 to December 2018. The clinical baseline data, treatment process, microbiological data, antibiotic susceptibility test of the bacterial isolates and outcomes were analyzed.ResultsA total of 10 patients were enrolled, including 4 males and 6 females. The average age of all patients was (44.90±17.03) years, the average age of peritoneal dialysis was (21.70±17.06) months. Seven cases were infected for the first time, and 3 cases were reinfected. The infections were mainly caused by mechanical failure of catheter connection system (3 cases) or enterogenous infection (3 cases). The main symptoms were abdominal pain (10 cases), fever (7 cases) and diarrhea (3 cases). Empirical anti-infective treatment was given after admission, only 1 case was effective, and the treatment of the other 9 cases were adjusted according to the results of drug sensitivity. Acinetobacter baumannii was sensitive to cefoperazone, carbapenem (meropenem, imipenem), quinolones (ciprofloxacin, levofloxacin), aminoglycosides (gentamicin) and polymyxin. Only one case was resistant to ceftazidime. Among the 10 patients, 8 cases were cured (continued peritoneal dialysis), 1 case died, and 1 case dropped out from peritoneal dialysis to hemodialysis.ConclusionsAcinetobacter baumannii peritoneal dialysis-related peritonitis in this hospital is mainly caused by mechanical disturbance of catheter connection system or enterogenic infection. Appropriate measures, including aseptic standard operation, follow-up and effective anti-infective treatment, should be taken to decrease the incidence and mortality of Acinetobacter baumannii peritoneal dialysis-related peritonitis.
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 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.
ObjectiveTo investigate the status of exit-site care in patients undergoing peritoneal dialysis, and analyze the relationship between exit-site care practice and exit-site infection.MethodsThe patients undergoing peritoneal dialysis in Nanfang Hospital, Southern Medical University between January and October 2019 were recruited by convenience sampling method. The Exit-site Schaefer Scale was used to diagnose the occurrence of exit-site infection. According to the guidelines of the International Society of Peritoneal Dialysis and relevant research, a questionnaire was developed to investigate the status of exit-site care in all peritoneal dialysis patients. Logistic regression analysis was used to analyze the influence of care practice on exit-site infection.ResultsA total of 208 peritoneal dialysis patients were recruited. There were 39 patients with (totally 43 times of) exit-site infections, with an exit-site infection incidence of 0.06 episodes per patient-year. The main bacteria were Staphylococcus aureus (30.2%) and Pseudomonas aeruginosa (16.3%). Of the 39 infected patients, 8 (20.5%) had peritonitis and 3 (7.7%) had been infected more than once. The exit-site Schaefer score of the 208 patients was 3.14±2.75. Of the 208 patients, 204 (98.1%) had received training of exit-site care from nurses, 166 (79.8%) could wash their hands and wear masks as required, 196 (94.2%) covered dressings on the exit site, and 184 (88.5%) fixed catheters, but the application of antibiotic ointment did not follow the latest guidelines. The logistic regression analysis revealed that the history of redness and swelling at the exit site [odds ratio (OR)=7.926, 95% confidence interval (CI) (2.367, 26.535), P=0.001] and the history of traction-associated bleeding [OR=5.750, 95%CI (1.878, 17.610), P=0.002] were risk factors of exit-site infection.ConclusionsExit-site infection is common in peritonealdialysis patients. Most patients can perform the exit-site care as required, but the care content is yet to be updated. Nursing staff should improve the training content according to the latest guidelines, strengthen the exit-site assessment, follow-up, and retraining, treat the redness and swelling at the exit site timely, and tell the patients to pay attention to catheter fixation and avoiding excessive traction, to prevent the exit-site infection and the further development of peritonitis.
ObjectiveTo observe the changes of blood flow density and perfusion density in the macula of non-diabetic peritoneal dialysis (PD) patients, and their correlation with blood pressure, total protein, albumin, prealbumin, serum creatinine, urea, and high-sensitivity C-reactive protein were preliminarily analyzed.MethodsA single-center, cross-sectional, clinical observational study. From January to December 2018, 63 eyes of 63 non-diabetic patients (non-diabetic PD group) and 75 eyes of normal healthy people (the normal control group) who underwent PD treatment at the PD Center of Peking University First Hospital were included in the study. All were monocular into the group. Among the 63 patients in the non-diabetic PD group, 24 were males and 39 were females. The duration of PD was 7 to 185 months, with the average duration of 67.87±48.36 months. There were 75 healthy persons in the normal control group. There was no significant difference in age (t=－0.558), sex ratio (χ2=0.492), axial length (t=－1.197), and BCVA between the two groups (P＞0.05). OCT angiography was used to scan the macular area of 3 mm×3 mm and 6 mm×6 mm in the subject’s right eye. The blood flow density and perfusion density of superficial retinal capillaries in the macular area, as well as the area, circumference, and morphological index of the foveal avascular zone (FAZ) were measured. The blood flow density and perfusion density at different locations in the macular area of the two groups of eyes were compared by independent sample t test. The blood pressure, total protein, albumin, prealbumin, serum creatinine, urea, and high-sensitivity C-reactive protein was performed by Pearson correlation analysis.ResultsCompared with the healthy control group, the blood flow density and perfusion density of superficial retinal capillaries in the macular area of the non-diabetic PD group decreased in different scanning ranges with the macular vessel 3×3 center (t=－2.409), the macular vessel 3×3 macular (t=－2.423), macular vessel 3×3 intact (t=－2.759), macular vessel 6×6 intact (t=－1.882), macular vessel 6×6 outer layer (t=－2.188), macular perfusion 3×3 center (t=－1.990), macular perfusion 3×3 complete (t=－2.719), macular perfusion 6×6 complete (t=－2.113), and macular perfusion 6×6 outer layer (t=－2.205). The difference was statistically significant (P＜0.05). The comparison of the macular FAZ area of the two groups of eyes was statistically significant (t=1.985, P＜0.05). Correlation analysis showed that 3×3 macular blood vessels were intact and mean arterial pressure was positively correlated (r=0.256, P=0.043). The macular blood vessels were 3×3 intact, macular perfusion was 3×3 intact, and macular blood was 6×6 intact, which the pre-white protein was positively correlated with (r=0.468, 0.362, 0.333; P＜0.001, P=0.004, 0.008). The macular vessel 3×3 was intact, the macular perfusion 6×6 was intact, which the hypersensitive C-reactive protein was negatively correlated with (r=－0.370, －0.287, P=0.005, 0.030).ConclusionThe superficial retinal blood flow density and perfusion density in the macular area of non-diabetic PD patients are lower than those of normal healthy people.
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.
