Objective To summarize the experience of open heart operation on neonates with critical and complex congenital heart diseases and evaluate the methods of perioperative management. Methods From May 2001 to January 2003, 12 patients of neonates with congenital heart diseases underwent emergency operation. Their operating ages ranged from 6 to 30 days, the body weights were 2.8 to 4.5 kg. Their diagnoses included D-transposition of the great arteries in 4 cases, ventricular septal defect with atrial septal defect in 5 cases, complete atrioventricular septal defect, obstructed supracardiac total anomalous pulmonary venous drainage and cardiac rhabdomyomas in 1 case respectively. 12 cases were operated under moderate or deep hypothermic cardiopulmonary bypass. Results All cases were observed in ICU for 2-11 days and discharged 7-19 days after operation. The postoperative complications included low cardiac output, mediastinal infection, respiratory distress syndrome, systemic capillary leak syndrome and acute renal failure. All cases were cured and the follow-up (from 6 months to 2 years) showed satisfactory outcome. Conclusion A particular cardiopulmonary bypass and proper perioperative management is very important to ensure the successful outcome. Peritoneal dialysis is an effective and safe method for treating acute renal failure after cardiac operation in neonates.
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.

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.
目的:探讨腹膜透析相关性腹膜炎的治疗。方法:回顾性分析的89例腹膜透析相关性腹膜炎患者,初期使用头孢菌素和或氨基糖甙类抗生素治疗,严重者使用头孢唑林和头孢他啶治疗。结果:89例腹膜炎患者透析液培养阳性33例(37.1%),其中19例1～4d治愈(21.3%),56例4～14 d治愈(62.9%),复发11例(12.4%),2例因尿毒症而全身衰竭死亡(2.2%)。结论:虽然腹膜透析相关性腹膜炎的发病率有降低趋势,但其仍然是腹膜透析最常见并发症之一,我们在强调对腹膜炎治疗的同时,更要强调对腹膜炎的预防。
目的 探讨持续性非卧床腹膜透析（CAPD）患者低钾血症的发生及临床特点。 方法 选取2002年12月－2011年12月采取持续非卧床腹膜透析治疗的47例尿毒症患者，就其透析过程中低钾血症发生情况进行总结分析。 结果 低钾血症31例（66%）；低钾血症组与非低钾血症组比较，低钾血症组血尿素氮、肌酐、血钠、血氯、血钙及白蛋白明显降低（P＜0.05）；两组年龄、性别、糖尿病肾病所占的比例及透析龄差异均无统计学意义（P＞0.05）。血钾水平随白蛋白浓度、血氯及血钙的提高而下降（OR=0.756， 0.772，0.022，P＜0.05）。 结论 密切联系、定期随诊观察CAPD患者，提高患者就诊依从性，及时发现与纠正低钾血症，有助于提高CAPD患者的生活质量与长期存活率。
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 and discuss the effects of lanthanum carbonate on serum calcium and phosphorus of continuous ambulatory peritoneal dialysis (CAPD) patients with chronic renal failure receiving calcitriol pulse therapy due to secondary hyperparathyroidism (SHPT). MethodsCAPD patients caused by SHPT in peritoneal dialysis centre of the Qingdao Municipal Hospital of Eastern Hospital from March to June, 2013 were selected and randomly divided into two groups (lanthanum carbonate group and calcium carbonate group). The lanthanum carbonate group were treated with oral lanthanum carbonate and calcitriol pulse therapy, while the calcium carbonate group were treated with calcium carbonate and calcitriol. Change of levels of serum calcium, phosphorus and iPTH were observed and statistic analysis was conducted using SPSS 17.0. ResultsA total of 40 CAPD patients were included, 20 cases in each group. After 12-week treatment, levels of serium phosphate (t=5.095, P=0.000) and iPTH (t=1.225, P=0.000) in the lanthanum carbonate group were significantly lower than those before treatment. The levels of serum calcium (t=1.127, P=0.001) and phosphate (t=2.035, P=0.000) in the lanthanum carbonate group were significantly lower than those in the calcium carbonate group (P < 0.05). ConclusionLanthanum carbonate serves as a useful approach to improve hypercalcemia and the hyperphosphatemia in CAPD patients receiving calcitriol pulse therapy due to SHPT.
