Abstract
Pediatric acute kidney support therapy (paKST) programs aim to reliably provide safe, effective, and timely extracorporeal supportive care for acutely and critically ill pediatric patients with acute kidney injury (AKI), fluid and electrolyte derangements, and/or toxin accumulation with a goal of improving both hospital-based and lifelong outcomes. Little is known about optimal ways to configure paKST teams and programs, pediatric-specific aspects of delivering high-quality paKST, strategies for transitioning from acute continuous modes of paKST to facilitate rehabilitation, or providing effective short- and long-term follow-up. As part of the 26th Acute Disease Quality Initiative Conference, the first to focus on a pediatric population, we summarize here the current state of knowledge in paKST programs and technology, identify key knowledge gaps in the field, and propose a framework for current best practices and future research in paKST.

Method to Alleviate Dilutional Coagulopathy Caused by Continuous Renal Replacement Therapy Introduction in a Low-Birth-Weight Neonate: A Case Report. Cureus 2023; 15:e39556. [PMID: 37378151 PMCID: PMC10292080 DOI: 10.7759/cureus.39556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/27/2023] [Indexed: 06/29/2023] Open
Abstract
Continuous renal replacement therapy (CRRT) in neonates and children has recently been used to treat hyperammonemia and metabolic disorders. However, CRRT introduction in low-birth-weight neonates is still a challenge due to vascular access limitations, bleeding complications, and a lack of neonatal-specific devices. We present the case of a low-birth-weight neonate whose severe coagulopathy due to CRRT introduction with a red cell concentration-primed circuit was alleviated by priming the new circuit with blood from the current circuit. This male preterm infant (birth weight: 1,935 g) was admitted to the pediatric intensive care unit at two days old with metabolic acidosis and hyperammonemia, which required CRRT. Following CRRT introduction, he showed marked thrombocytopenia (platelet count: 305,000-59,000/μL) and coagulopathy (prothrombin time international normalized ratio (PT/INR) >10), necessitating platelet and fresh frozen plasma transfusions. Upon circuit exchange, we primed the new circuit with blood from the current circuit. This resulted in only a slight worsening of thrombocytopenia (platelet count: 56,000-32,000/μL) and almost no change in coagulation (PT/INR: 1.42-1.54). We also reviewed the literature regarding safe CRRT management in low-birth-weight neonates. Since there is no established method for the use of blood from the current circuit during circuit exchange, this should be addressed in future work.

Blood Purif 2022; 51:959-966. [DOI: 10.1159/000522258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 01/25/2022] [Indexed: 11/19/2022]
Abstract
<b><i>Introduction:</i></b> When starting continuous renal replacement therapy (CRRT), vasopressor-dependent patients are at risk of hemodynamic instability. Thus far, only a few studies have analyzed the impact of CRRT circuit replacement for vasopressor-dependent patients. Hence, we compared the effect of double-machine replacement protocol (DMRP) with single-machine replacement protocol (SMRP) for CRRT circuit replacement in vasopressor-dependent patients. <b><i>Methods:</i></b> The medical records of 96 vasopressor-dependent patients treated with CRRT in the general intensive care unit of the Shunde Hospital, Southern Medical University, between January 2017 and April 2018 were retrospectively analyzed. The major measures of the SMRP included returning the blood to the patient and sealing access catheter with heparin and starting a new CRRT machine with a slow blood pump, while DMRP involved simultaneous drawing and return of blood with two machines using a slow blood pump for circuit replacement. The primary outcome measures were changes in vasopressor dose and hemodynamic parameters, and the secondary outcome measure was the pause time difference between the two groups during the period. <b><i>Results:</i></b> A total of 53 patients were treated with SMRP and 43 patients with DMRP. Heart rate was higher in the SMRP group as compared to the DMRP group (<i>p</i> < 0.05). There were no significant changes in central venous pressure, mean arterial pressure, and vasopressor dose in either group (<i>p</i> > 0.05). The patients in the DMRP group had a significant reduction in CRRT pause time (5.62 ± 0.69 min in DMRP group vs. 37.01 ± 8.72 min in SMRP group, <i>p</i> < 0.01). The DMRP group needed a lower volume of circuit purging and priming fluid related to CRRT circuit replacement (0 mL in DMRP group vs. 463 mL in SMRP group). <b><i>Conclusions:</i></b> Implementation of the DMRP for CRRT circuit replacement had a slight hemodynamic effect on vasopressor-dependent patients. It also reduced the pause time and volume of circuit purging and priming fluid related to CRRT circuit replacement compared with SMRP.

Abstract
Hematopoietic stem cell transplant (HSCT) is a curative therapy for malignant and non-malignant conditions. However, complications post-HSCT contribute to significant morbidity and mortality in this population. Acute kidney injury (AKI) is common in the post-allogeneic transplant phase and contributes to morbidity in this population. Continuous renal replacement therapy (CRRT) is used often in the setting of AKI or multiorgan dysfunction in critically ill children. In addition, CRRT can be useful in many disease processes related to transplant and can potentially improve outcomes in this population. This review will focus on the use of CRRT in critically ill children in the post-HSCT setting outside the realm of acute renal failure and highlight the benefits and applications of this modality in this high-risk population.

Hemofiltration circuit use beyond 72 hours in pediatric continuous renal replacement therapy. Int J Artif Organs 2012; 35:139-43. [PMID: 22388940 DOI: 10.5301/ijao.5000013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/14/2011] [Indexed: 11/20/2022]
Abstract
INTRODUCTION During continuous renal replacement therapy (CRRT), hemofiltration circuits ideally are changed after 72 h since tubing integrity and flow rates are not guaranteed after this time interval. This potential risk must be weighed against the risk of hypotension during elective circuit changes in the unstable patient. The aim of this study was to examine the safety of circuits used beyond 72 h in pediatric CRRT. METHODS A retrospective chart review of all patients who underwent CRRT at our institution from January 2003 to October 2005 was performed. Procedures were divided into standard (≤72 h) and extended (>72 h) circuit duration groups. Patients who had more than one CRRT procedure (n=13) were excluded from study. RESULTS 71 CRRT procedures were performed for 71 patients. A total of 254 circuits were used, of which 64 (25%) were used for >72 h. For circuits >72 h, the mean duration of use was 5.5 days ± 1.8 (range 4-11). There were no differences between the groups in age (p=0.12), weight (p=0.48), diagnosis (p=0.21), CRRT indication (p=0.07), CRRT mode (p=0.37), anticoagulation (p=0.53), blood flow rate (p=0.06), replacement rate (p=0.50) or dialysate rate (p=0.89). There were no incidents of membrane or tubing rupture in either group. CONCLUSIONS Use of hemofiltration circuits beyond 72 h may be safe in pediatric patients undergoing CRRT without increased risk of tubing rupture. Our data suggest a need to redefine the limits of prolonged circuit use in pediatric CRRT.

Abstract
BACKGROUND The simultaneous use of plasma-exchange (PE) and haemodialysis (HD), known as tandem PE and HD (TPH), may be an additional resource for treating patients who need both therapies at the same time. However, little experience is reported in the paediatric setting. CASE-DIAGNOSIS/TREATMENT We retrospectively reviewed the TPH sessions performed in the last 5 years in our unit. Thirty-nine TPH treatments in eight pediatric patients were traced. The median age of the patients was 10.5 (range 5.1-19.2) years, and median weight was 27.6 (range 14.7-66.2) kg. Indications for TPH were atypical haemolytic uremic syndrome due to factor H or factor I dysregulation, or to a not yet defined abnormality, in most of the sessions (34/39 sessions). The remaining five sessions were performed for vasculitis, focal segmental glomerulosclerosis and hyperimmunization in a patient waiting for kidney transplant. In all treatments, TPH was completed and reached the desired ultrafiltration and substitution volumes; the duration of PE was shorter than that of HD. No significant adverse events were observed. CONCLUSIONS In those rare patients who require both PE and HD, TPH can improve their quality of life by reducing the time spent in extracorporeal circulation. This tandem treatment is safe and well-tolerated, even in subjects of relatively small body size.

Continuous renal replacement therapy results in respiratory and hemodynamic beneficial effects in pediatric patients with severe systemic inflammatory response syndrome and multiorgan system dysfunction. Pediatr Crit Care Med 2010; 11:737-40. [PMID: 20068503 DOI: 10.1097/pcc.0b013e3181ce7593] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Proinflammatory mediators have been implicated in the pathogenesis of systemic inflammatory response syndrome and multiorgan system dysfunction. These mediators are of molecular weights that render them amenable to clearance by the hemodiafiltration mode of continuous renal replacement therapy. OBJECTIVE To determine whether a period of 48 hrs of continuous renal replacement therapy in patients with multiorgan system dysfunction secondary to systemic inflammatory response syndrome improves their degree of anasarca as well as their cardiovascular and respiratory systems performances. DATA SOURCE Retrospective chart review. STUDY DESIGN Charts of patients diagnosed with systemic inflammatory response syndrome, who were mechanically ventilated in the pediatric intensive care unit and at the same time were receiving continuous renal replacement therapy, from 2004 to 2008, were reviewed. Patients with preexisting renal failure and/or received extracorporeal membrane oxygenation were excluded. Changes in the patients' body weights, oxygenation indices, and vasopressor scores were used as markers for responsiveness to continuous renal replacement therapy. DATA ANALYSIS AND MAIN RESULTS: Data from twenty-two patients with systemic inflammatory response syndrome and with three to five concomitantly diagnosed organ system dysfunctions, at the time continuous renal replacement therapy was initiated, were analyzed. None of the six patients who had five organ system dysfunctions survived to be discharged from the pediatric intensive care unit. Of the remaining 16 patients with three or four organ system dysfunctions, eight (50%) survived and eight (50%) died. The patients' weight, oxygenation indices, and vasopressor scores did not significantly change with 48 hrs of continuous renal replacement therapy. CONCLUSIONS Mechanically ventilated patients with systemic inflammatory response syndrome and multiorgan system dysfunction demonstrated a precarious and insignificant response to 48 hrs of continuous renal replacement therapy in a hemodiafiltration mode. However, the patients' overall clinical status did not deteriorate during this therapy. More prospective studies are necessary to determine the effectiveness of continuous renal replacement therapy in patients with multiorgan system dysfunction.
