OBJECTIVES:
To evaluate the effect of fluid load on the prognosis of children with sepsis-associated acute kidney injury (AKI) undergoing continuous renal replacement therapy (CRRT).
METHODS:
A total of 121 children who underwent CRRT for sepsis-associated AKI from August 2018 to March 2021 were enrolled in the retrospective study. According to the fluid load from admission or disease progression to CRRT, they were divided into three groups: low fluid load (fluid load: <5%; n=35), high fluid load (fluid load: 5% - <10%; n=35), and fluid overload (fluid load: ≥10%; n=51). Baseline data and clinical biochemical data before CRRT were collected for comparison and analysis. The Kaplan-Meier survival curve analysis was used for comparison of 28-day survival between groups. The multivariate logistic regression model was used to identify the influencing factors for the prognosis of the children.
RESULTS:
The survival analysis showed that the fluid overload group had a significantly higher 28-day mortality rate than the low fluid load and high fluid load groups (P<0.05). The multivariate logistic regression analysis showed that an increase in fluid overload volume was a risk factor for increased 28-day mortality in the fluid overload group, while earlier initiation of CRRT was a protective factor (P<0.05).
CONCLUSIONS
Fluid overload before CRRT may increase the mortality in children with sepsis-associated AKI, and CRRT should be performed for these children as early as possible.

Objective: To explore the application effects of bundle nursing of citric acid extracorporeal anticoagulation on continuous renal replacement therapy (CRRT) of severe burn patients. Methods: A non-randomized controlled study was conducted. Forty-six patients who met the inclusion criteria and received regular nursing of citric acid extracorporeal anticoagulation during CRRT in the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from January to December 2017 were included in regular nursing group (30 males and 16 females, aged 42.0 (38.7,47.0) years, with 201 times of CRRT performed), and 48 patients who met the inclusion criteria and received bundle nursing of citric acid extracorporeal anticoagulation during CRRT in the same hospital from January to December 2018 were included in bundle nursing group (32 males and 16 females, aged 41.0 (36.0,46.0) years, with 164 times of CRRT performed). The clinical data of all the patients in the two groups were recorded, including the length of intensive care unit (ICU) stay, total cost of treatment in ICU, cost of CRRT, unplanned ending of treatment, ending of treatment due to operation (with the rates of unplanned ending of treatment and ending of treatment due to operation calculated), times of disposable hemodialysis filter and supporting pipeline filter (hereinafter referred to as filter) with use time>24 h, times of CRRT, and lifetime of filter. For the patients in both groups who continuously received CRRT for 3 days or more from the first treatment, the prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), total calcium, ionic calcium (with the difference of total calcium or ionic calcium between before and after treatment calculated), creatinine, urea, β2 microglobulin, cystatin C, platelet count, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid levels before the first treatment (hereinafter referred to as before treatment) and 3 days after the first treatment (hereinafter referred to as after 3 days of treatment). The treatment-related complications of all patients in the two groups were recorded during hospitalization. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, and chi-square test. Results: Compared with those in regular nursing group, the length of ICU stay was significantly shortened (Z=-4.71, P<0.01), the total cost of treatment in ICU was significantly reduced (t=-1.39, P<0.01), the cost of CRRT had no significant change (P>0.05), the rates of unplanned ending of treatment and ending of treatment due to operation were both significantly decreased (with χ2 values of 12.20 and 17.83, respectively, P<0.01), the times of filter service time>24 h was increased significantly (Z=-5.93, P<0.01), the times of CRRT were significantly reduced (Z=-4.75, P<0.01), and the filter service life was significantly prolonged (Z=-9.24, P<0.01) among patients in bundle nursing group. Thirty-one patients in bundle nursing group and 28 patients in regular nursing group continuously received CRRT for 3 days or more from the first treatment. Before treatment, PT, APTT, and INR of patients in bundle nursing group were 24.10 (16.08, 39.20) s, 38.81 (32.32, 45.50) s, and 1.17 (1.12, 1.19), respectively, similar to 31.75 (22.99, 40.96) s, 41.82 (35.05, 48.06) s, and 1.15 (1.11, 1.19) of patients in regular nursing group (P>0.05); the levels of total calcium and ionic calcium of patients in the two groups were similar (P>0.05). After 3 days of treatment, PT, APTT, and INR of patients in bundle nursing group and regular nursing group were 29.06 (20.11, 39.46) s, 35.25 (30.06, 40.28) s, 1.13 (1.09, 1.17) and 36.51 (26.64, 42.92) s, 39.89 (34.81, 46.62) s, 1.14 (1.10, 1.18), respectively, similar to those before treatment (P>0.05); the level of ionic calcium of patients in regular nursing group was significantly higher than that before treatment (Z=-2.08, P<0.05); the levels of total calcium and ionic calcium of patients in bundle nursing group were both significantly higher than those before treatment (with Z values of -3.55 and -3.69, respectively, P<0.01); compared with those in regular nursing group, APTT of patients was significantly shorter (Z=-2.29, P<0.05), while the total calcium level of patients was significantly higher in bundle nursing group (Z=-2.26, P<0.05). The difference of total calcium between before and after treatment of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-3.15, P<0.01). The differences of ionic calcium between before and after treatment of patients in the two groups were similar (P>0.05). Before treatment, the level of β2 microglobulin of patients in bundle nursing group was significantly higher than that in regular nursing group (Z=-2.84, P<0.01), the platelet count of patients in bundle nursing group was significantly lower than that in regular nursing group (Z=-2.44, P<0.05), while the levels of creatinine, urea, cystatin C, mean arterial pressure, pH value, oxygenation index, bicarbonate radical, and lactic acid of patients in the two groups were similar (P>0.05). After 3 days of treatment, the levels of creatinine, urea, β2 microglobulin, cystatin C, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -2.10, -2.90, -3.11, -2.02, -2.34, -2.63, and -2.84, respectively, P<0.05 or P<0.01), while the levels of platelet count, oxygenation index, and mean arterial pressure of patients were all significantly higher than those before treatment in bundle nursing group (with Z values of -6.65 and -2.40, respectively, t=-9.97, P<0.05 or P<0.01); the levels of creatinine, urea, β2 microglobulin, cystatin C, platelet count, pH value, bicarbonate radical, and lactic acid of patients were all significantly lower than those before treatment (with Z values of -5.32, -2.31, -2.41, -2.21, -3.68, -2.93, -2.20, and -2.31, respectively, P<0.05 or P<0.01), while the oxygenation index and mean arterial pressure of patients were both significantly higher than those before treatment in regular nursing group (Z=-5.59, t=-7.74, P<0.01). After 3 days of treatment, compared with those in regular nursing group, the levels of creatinine, cystatin C, platelet count, oxygenation index, bicarbonate radical, and mean arterial pressure of patients were all significantly higher (with Z values of -2.93, -1.99, -6.39, -2.09, and -2.52, respectively, t=-3.28, P<0.05 or P<0.01), while the levels of urea, β2 microglobulin, pH value, and lactic acid of patients were all significantly lower (with Z values of -3.87, -2.58, -4.24, and -2.75, respectively, P<0.05 or P<0.01) in bundle nursing group. During hospitalization, there were no treatment-related bleeding events or hypernatremia related to citric acid treatment of patients in the two groups. The ratio of total calcium to ionic calcium in one patient in bundle nursing group was >2.5, but there was no manifestation of citric acid accumulation poisoning; 1 patient had hypoionic calcemia, and 1 patient had severe metabolic alkalosis. Five patients had hypoionic calcemia and 2 patients had severe metabolic alkalosis in regular nursing group. Conclusions: The implementation of bundle nursing of citric acid extracorporeal anticoagulation during CRRT for severe burn patients shortens the length of ICU stay, reduces the total cost of treatment in ICU and the occurrence of treatment-related complications, relieves the economic burden of patients, and improves the continuity and quality of treatment.

OBJECTIVE:
To investigate the incidence and risk factors of hypothermia in patients with acute renal injury (AKI) receiving continuous renal replacement therapy (CRRT), and to compare the effects of different heating methods on the incidence of hypothermia in patients with CRRT.
METHODS:
A prospective study was conducted. AKI patients with CRRT who were admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to December 2022 were enrolled as the study subjects. Patients were divided into dialysate heating group and reverse-piped heating group according to randomized numerical table method. Both groups were provided with reasonable treatment mode and parameter setting by the bedside physician according to the patient's specific condition. The dialysis heating group used the AsahiKASEI dialysis machine heating panel to heat the dialysis solution at 37 centigrade. The reverse-piped heating group used the Barkey blood heater from the Prismaflex CRRT system to heat the dialysis solution, and the heating line temperature was set at 41 centigrade. The patient's temperature was then continuously monitored. Hypothermia was defined as a temperature lower than 36 centigrade or a drop of more than 1 centigrade from the basal body temperature. The incidence and duration of hypothermia were compared between the two groups. Binary multivariate Logistic regression analysis was used to explore the influencing factors of hypothermia during CRRT in AKI patients.
RESULTS:
A total of 73 patients with AKI treated with CRRT were eventually enrolled, including 37 in the dialysate heating group and 36 in the reverse-piped heating group. The incidence of hypothermia in the dialysis heating group was significantly lower than that in the reverse-piped heating group [40.5% (15/37) vs. 69.4% (25/36), P < 0.05], and the hypothermia occurred later than that in the reverse-piped heating group (hours: 5.40±0.92 vs. 3.35±0.92, P < 0.01). Patients were divided into hypothermic and non-hypothermic groups based on the presence or absence of hypothermia, and a univariate analysis of all indicators showed a significant decrease in mean arterial pressure (MAP) in hypothermic patients (n = 40) compared with the non-hypothermic patients [n = 33; mmHg (1 mmHg ≈ 0.133 kPa): 77.45±12.47 vs. 94.42±14.51, P < 0.01], shock, administration of medium and high doses of vasoactive drug (medium dose: 0.2-0.5 μg×kg-1×min-1, high dose: > 0.5 μg×kg-1×min-1) and CRRT treatment were significantly increased [shock: 45.0% (18/40) vs. 6.1% (2/33), administration of medium and high doses of vasoactive drugs: 82.5% (33/40) vs. 18.2% (6/33), administration of CRRT (mL×kg-1×h-1): 51.50±9.38 vs. 38.42±10.97, all P < 0.05], there were also significant differences in CRRT heating types between the two groups [in the hypothermia group, the main heating method was the infusion line heating, which was 62.5% (25/40), while in the non-hypothermia group, the main heating method was the dialysate heating, which was 66.7% (22/33), P < 0.05]. Including the above indicators in a binary multivariate Logistic regression analysis, it was found that shock [odds ratio (OR) = 17.633, 95% confidence interval (95%CI) was 1.487-209.064], mid-to-high-dose vasoactive drug (OR = 24.320, 95%CI was 3.076-192.294), CRRT heating type (reverse-piped heating; OR = 13.316, 95%CI was 1.485-119.377), and CRRT treatment dose (OR = 1.130, 95%CI was 1.020-1.251) were risk factors for hypothermia during CRRT in AKI patients (all P < 0.05), while MAP was protective factor (OR = 0.922, 95%CI was 0.861-0.987, P < 0.05).
CONCLUSIONS
AKI patients have a high incidence of hypothermia during CRRT treatment, and the incidence of hypothermia can be effectively reduced by heating CRRT treatment fluids. Shock, use of medium and high doses of vasoactive drug, CRRT heating type, and CRRT treatment dose are risk factors for hypothermia during CRRT in AKI patients, with MAP is a protective factor.

OBJECTIVES:
To study the role of plasma exchange combined with continuous blood purification in the treatment of refractory Kawasaki disease shock syndrome (KDSS).
METHODS:
A total of 35 children with KDSS who were hospitalized in the Department of Pediatric Intensive Care Unit, Hunan Children's Hospital, from January 2019 to August 2022 were included as subjects. According to whether plasma exchange combined with continuous veno-venous hemofiltration dialysis was performed, they were divided into a purification group with 12 patients and a conventional group with 23 patients. The two groups were compared in terms of clinical data, laboratory markers, and prognosis.
RESULTS:
Compared with the conventional group, the purification group had significantly shorter time to recovery from shock and length of hospital stay in the pediatric intensive care unit, as well as a significantly lower number of organs involved during the course of the disease (P<0.05). After treatment, the purification group had significant reductions in the levels of interleukin-6, tumor necrosis factor-α, heparin-binding protein, and brain natriuretic peptide (P<0.05), while the conventional group had significant increases in these indices after treatment (P<0.05). After treatment, the children in the purification group tended to have reductions in stroke volume variation, thoracic fluid content, and systemic vascular resistance and an increase in cardiac output over the time of treatment.
CONCLUSIONS
Plasma exchange combined with continuous veno-venous hemofiltration dialysis for the treatment of KDSS can alleviate inflammation, maintain fluid balance inside and outside blood vessels, and shorten the course of disease, the duration of shock and the length of hospital stay in the pediatric intensive care unit.

Objective: To investigate the prognosis factors for death within 90 days after discharge in patients with acute kidney injury(AKI) treated requiring continuous renal replacement therapy(CRRT) undergoing surgery for acute Standford type A aortic dissection. Methods: The clinic data of 126 patients undergoing CRRT for postoperative AKI after acute type A aortic dissection surgery in the Center for Cardiac Intensive Care, Beijing Anzhen Hospital from July 2016 to February 2019 were analyzed retrospectively. There were 83 males and 43 females, aging (52.9±11.2) years(range: 25 to 70 years). The patients' demographic characteristics, disease-related information, perioperative data, laboratory indexes during CRRT, complications, and survival information within 90 days after discharge were recorded. Independent prognosis factors for death within 90 days of discharge were determined by Kaplan-Meier survival analysis, univariate and multifactorial Cox regression analysis. Results: Totally 57 of 126 patients(45.2%) died over the first 90 days after discharge. Kaplan-Meier survival analysis and univariate Cox regression analysis showed that there were significant differences between the non-survival and survival group including ≥65 years old, high lactate values 12 hours after CRRT, pulmonary infection, liver dysfunction, presence of permanent neurological complications, and postoperative ejection fraction(EF)<45%. Multifactorial Cox regression analysis revealed that ≥65 years old(HR=2.14, 95%CI: 1.09 to 4.21, P=0.03), high lactate values 12 hours after CRRT(HR=1.13, 95%CI: 1.06 to 1.20, P=0.01) and postoperative EF<45%(HR=2.21, 95%CI: 1.09 to 4.51, P=0.03) were independent prognosis factors for patients' death within 90 days after hospital discharge. Conclusions: ≥65 years old, high lactate values 12 hours after CRRT and postoperative EF<45% are independent prognosis factors for death within 90 days after discharge in patients undergoing CRRT for AKI after acute type A aortic dissection surgery. Proper identification and management of prognosis factors could be beneficial to improve patients' outcomes.

Journal of the Korean Association of Pediatric Surgeons 2003;9(2):77-80
Continuous Ambulatory Peritoneal Dialysis (CAPD) has now become an established form of renal replacement therapy in children. Despite of technical improvements, there are various complications in CAPD. We reviewed medical records of children who received CAPD at Seoul National University Children's Hospital in the period between May 1991 and June 2002. Ninety-three procedures of CAPD catheter insertion in 70 patients were included in this study. Complication rate was 64.5%, and CAPD catheter related peritonitis was most common. In conclusion, CAPD catheter related peritonitis develops in considerable number of pediatric patients. Although the peritonitis could be treated with empirical antibiotics therapy, further investigation to prevent complication is required.

Continuous ambulatory peritoneal dialysis (CAPD) is an effective renal replacement therapy for the end stage renal disease. The hydrothorax secondary to leakage of dialysate via pleuroperitoneal communication is a rare complication of CAPD. A variety of symptoms are complained. The regular chest X-ray and pleural fluid examination are needed to find out this complication with vague symptoms. Although our understanding of its mechanisms is incomplete, it is apparent that the key to successful therapy is obliteration of a transdiaphragmatic route of dialysate leakage (pleuroperitoneal communication). Several treatments of CAPD-induced hydrothorax have included pleurodesis with tetracycline, talc, fibrin, or autologous blood and surgical treatment. We have recently managed with a patient CAPD-induced massive hydrothorax with decreased amount of effluent dialysate volumes using talc pleurodesis. This patient was successfully returned to CAPD.

BACKGROUND: Continuous ambulatory peritoneal dialysis (CAPD) has become firmly established as an effective mode of renal replacement therapy. The purpose of this study was to understand the clinical courses in stable CAPD patients. METHODS: Fifty-four patients were analyzed with residual renal function (RRF), adequacy of dialysis (such as weekly Kt/V), urine volume, normalized protein catabolic rate (nPCR), serum albumin and dialysate CA125. We retrospectively compared the changes of several indices at mean 5.8 months and mean 31.3 months after initiation of CAPD. RESULTS: During CAPD, body weight was significantly increased (59.6+/-10.9 vs. 62.7+/-10.6 kg, p < 0.01: 2.9 kg/year) but RRF (2.61+/-2.78 vs. 2.02+/-2.73 mL/min, p < 0.05) were significantly decreased with time. Higher RRF group showed higher nPCR (1.07+/-0.36 vs. 0.89+/-0.15 g/kg/day, p < 0.01) and higher weekly Kt/V (2.49+/-0.66 vs. 1.97+/-0.40, p < 0.01). DM group showed lower dialysate CA125 (17.34+/-6.83 vs. 28.03+/-19.08 U/mL, p < 0.05) and lower serum albumin. From the beginning, hypoalbuminemic patients showed higher 4hr (D/P)Cr (0.68+/-0.11 vs. 0.59+/-0.12, p < 0.05). Serum albumin was negatively correlated with 4hr (D/P)Cr (r=-0.308, p=0.008). CONCLUSION: Stable CAPD patients showed weight gain and decrement of RRF with time. And better RRF group showed better clinical indices (nPCR, wKt/V). We can conclude that maintaining of RRF will be important to keep better clinical courses of CAPD patients. Further study (including effect of peritonitis) will be necessary to evaluate the clinical courses of CAPD patients.
