Correlation between early computed tomography findings and neurological outcome in pediatric traumatic brain injury patients.

Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in children. Head computed tomography (CT) is frequently utilized for evaluating trauma-related characteristics, selecting treatment options, and monitoring complications in the early stages. This study assessed the relationship between cranial CT findings and early and late neurological outcomes in pediatric TBI patients admitted to the pediatric intensive care unit (PICU). The study included children aged 1 month to 18 years who were admitted to the PICU due to TBI between 2014 and 2020. Sociodemographic data, clinical characteristics, and cranial CT findings were analyzed. Patients were categorized based on their Glasgow Coma Scale (GCS) score. Of the 129 patients, 83 (64%) were male, and 46 (36%) were female, with a mean age of 6.8 years. Falls (n = 51, 39.5%) and in-vehicle traffic accidents (n = 35, 27.1%) were the most common trauma types observed. Normal brain imaging findings were found in 62.7% of the patients, while 37.3% exhibited intracranial pathology. Hemorrhage was the most frequent CT finding. Severe TBI (n = 26, p = 0.032) and mortality (n = 9, p = 0.017) were more prevalent in traffic accidents. The overall mortality rate in the study population was 10.1%. In children with TBI, cranial CT imaging serves as an essential initial method for patients with neurological manifestations. Particularly, a GCS score of ≤ 8, multiple hemorrhages, diffuse cerebral edema, and intraventricular bleeding are associated with sequelae and mortality.

The impact of fragmented QRS on clinical findings and outcomes in children with dilated cardiomyopathy with or without left ventricular non-compaction.

OBJECTIVE: The aim of this study is to investigate the frequency of fragmented QRS and its associations with clinical findings and prognosis in children diagnosed with dilated cardiomyopathy with or without left ventricular non-compaction. METHODS: This retrospective study was conducted between 2010 and 2020. Patients with dilated cardiomyopathy were classified into two groups according to the presence of left ventricular non-compaction: Dilated cardiomyopathy with left ventricular non-compaction and dilated cardiomyopathy without left ventricular non-compaction. Patients were also divided into two groups according to the presence of fragmented QRS (fragmented QRS group and non-fragmented QRS group). RESULTS: Twenty-three of 44 patients (52.3%) were male. Among left ventricular non-compaction patients, the fragmented QRS group had more complex ventricular arrhythmias (p = 0.003). Patients with fragmented QRS had a significantly higher rate of major adverse cardiac events and/or cardiac death in both cardiomyopathy groups (p = 0.003 and p = 0.005). However, the rate of major adverse cardiac events and/or cardiac death was similar between dilated cardiomyopathy patients with and without left ventricular non-compaction. Multivariate logistic regression analysis showed that the presence of fragmented QRS strongly predicts major adverse cardiac events and/or cardiac death (odds ratio, 31.186; 95% confidence interval, 2.347-414.307). Although the survival rates between cardiomyopathy groups were similar, patients with fragmented QRS had a markedly lower survival rate during the follow-up period, as mean of 15 months (p = 0.001). CONCLUSION: Our study showed that the presence of fragmented QRS may be an important ECG sign predicting an major adverse cardiac event and/or cardiac death in patients with dilated cardiomyopathy. We believe that recognising fragmented QRS could be valuable in forecasting patient prognosis and identifying high-risk patients who require additional support.

Cardiovascular manifestations and cardiac magnetic resonance follow-up of multisystem inflammatory syndrome in children (MIS-C).

OBJECTIVE: This study aimed to evaluate the cardiovascular manifestations and surveillance of multisystem inflammatory syndrome in children (MIS-C) and to determine the correlation of echocardiographic findings with cardiac magnetic resonance imaging findings. METHODS: Forty-four children diagnosed as MIS-C with cardiac involvement were enrolled in this observational descriptive study. The diagnosis of MIS-C was made according to the criteria of Centers for Disease Control and Prevention. Clinical findings, laboratory parameters, and electrocardiographic and echocardiographic findings at the time of diagnosis and during follow-up were evaluated. Cardiac magnetic resonance was performed on 28 (64%) cases. The 1-year follow-up imaging was performed in all cases with abnormal initial cardiac magnetic resonance findings. RESULTS: Forty-four patients (56.8% male) with a mean age of 8.5 ± 4.8 years were enrolled in this study. There was a significant positive correlation between high-sensitivity cardiac troponin T (mean: 162 ± 444.4 pg/ml) and N-terminal pro b-type natriuretic peptide (mean: 10,054 ± 11,604 pg/ml) (p < 0.01). Number of cases with an electrocardiographic and echocardiographic abnormality was 34 (77%) and 31 (70%), respectively. Twelve cases (45%) had left ventricular systolic dysfunction and 14 (32%) cases had pericardial effusion on admission. Three cases (11%) had cardiac magnetic resonance findings that may be attributed to the presence of myocardial inflammation, and pericardial effusion was present in seven (25%) cases. Follow-up cardiac magnetic resonances of all cases were normal. Cardiac abnormalities were completely resolved in all except two cases. CONCLUSIONS: Myocardial involvement can be seen during acute disease, but MIS-C generally does not lead to prominent damage during a year of surveillance. Cardiac magnetic resonance is a valuable tool to evaluate the degree of myocardial involvement in cases with MIS-C.

Antidepressant Poisoning Trends in Pediatric Intensive Care: A Comparative Study of New- and Old-Generation Antidepressants.

PURPOSE/BACKGROUND: This study aimed to compare the frequency, clinical findings, treatment practices, and outcomes of toxicity to old-generation (OG) and new-generation (NG) antidepressants in our pediatric intensive care unit (PICU) by year-to-year. METHODS/PROCEDURES: The study included patients hospitalized for antidepressant poisoning during the 11-year period of January 2010 through December 2020. Antidepressants were classified as OG and NG. The groups were compared in terms of patient demographic characteristics, type of poisoning (accidental/suicidal), clinical findings, supportive and extracorporeal treatments received, and outcomes. FINDINGS/RESULTS: The study included 58 patients (NG, n = 30; OG, n = 28). The median age of the patients was 178 months (range, 13.6-215 months) and 47 patients (81%) were female. Patients admitted for only antidepressant poisoning constituted 13.3% of all poisoning cases (58/436). Of these, 22 cases (37.9%) were accidental and 36 (62.3%) were suicidal. The most common cause of poisoning was amitriptyline (24/28) in the OG group and sertraline (13/30) in the NG group. Neurological symptoms were significantly more common in the OG group (76.2% vs 23.8%), while gastrointestinal involvement was more common in the NG group (82% vs 18%; P = 0.001 and P = 0.026, respectively). Old-generation antidepressant poisoning was associated with more frequent intubation (4 vs 0 patients, P = 0.048) and longer length of PICU stay (median, 1 day [range, 1-8] vs 1 day [range, 1-4], P = 0.019). Rates of therapeutic plasma exchange and intravenous lipid emulsion therapy did not differ ( P = 0.483 and P = 0.229, respectively). IMPLICATIONS/CONCLUSIONS: In poisoned patients, proper evaluation and management of patients requiring PICU admission are vital for favorable patient outcomes.

Predictors of kidney complications and analysis of hypertension in children with allogeneic hematopoietic stem cell transplantation.

BACKGROUND: This study aimed to determine incidence of kidney complications in pediatric allogeneic hematopoietic stem cell transplantation (HSCT) patients. METHODS: Pediatric allogeneic HSCT patients were included. Post-transplantation urinary system complications were collected from medical records and glomerular filtration rates at last visit compared with clinical parameters. Additionally, 24-h ambulatory blood pressure monitoring was performed. RESULTS: The study included 165 pediatric patients. Acute kidney injury (AKI) developed in 125 (75.8%) patients of whom 54 (43.2%) had stage 1, 36 (28.8%) stage 2, and 35 (28%) stage 3 AKI. Primary malignant disease and viral infection post-HSCT were associated with increased risk of AKI (OR: 4; 95%CI: 1.2-13, p = 0.022 and OR: 2.9; 95%CI: 1.2-6.8, p = 0.014, respectively). Mean duration of post-HSCT follow-up was 4.4 ± 2.5 years, during which time 8 patients had chronic kidney disease (CKD) (stage 1, 4 patients; stage 2, 3 patients; stage 3, 1 patient). CKD incidence was higher in patients in whom stem cell product was bone marrow + cord blood and mobilized peripheral blood, compared to bone marrow alone (40-37.5% versus 5.1%, p = 0.002). Based on 24-h ABPM, 14.7% and 7.4% of patients with normal office blood pressure had pre-hypertension and hypertension, respectively. In patients with albuminuria/severe albuminuria, daytime and nighttime systolic SDS scores were higher than those without albuminuria/severe albuminuria (p = 0.010 and p = 0.004, respectively). CONCLUSIONS: Incidence of AKI is higher in pediatric HSCT patients with primary malignant disease and those with documented viral infection. Our study highlights the beneficial role of 24-h ABPM as a routine part of standard care of pediatric HSCT recipients.

Acute kidney injury in critically ill children with COVID-19 and MIS-C.

BACKGROUND: This study's objective was to investigate the incidence of acute kidney injury (AKI) in children with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and multisystem inflammatory syndrome (MIS-C) and to report our clinical experience. METHODS: Acute COVID-19 and MIS-C-diagnosed patients observed in two pediatric intensive care units (PICUs) between 2019 and 2021 were examined for AKI and retrospectively compared to children with AKI. RESULTS: The study comprised 163 children, of whom 98 (60.1%) were diagnosed with acute COVID-19 and 65 (39.9%) with MIS-C. AKI was observed in 40 (40.8%) of the acute COVID-19 patients and 18 (27.7%) of the MIS-C patients. Low calcium level and hypotension were linked with AKI at initial presentation (OR: 0.56, 95% CI: 0.369-0.560, p = 0.006 and OR: 3.64, 95% CI: 1.885-7.152, p = 0.001, respectively). A history of nephrotoxic medication usage played an essential role in the development of AKI in patients who acquired AKI after hospitalization (p = 0.001, odds ratio: 9.32, confidence interval: 3.106-27.973). In clinical practice, individuals with respiratory distress and cough had a high chance of having AKI (OR: 4.47, 95% confidence interval: 2.25-8,892 and OR: 3.48, 95% confidence interval: 1.76-6.88). AKI patients had a greater demand for respiratory assistance and a longer period of stay in the PICU. CONCLUSIONS: AKI in the COVID-19 and MIS-C patient groups is related with increased mortality and extended hospitalization, according to the findings. These statistics imply that identifying and preventing risk factors is necessary. A higher resolution version of the Graphical abstract is available as Supplementary information.

Prolonged extracorporeal membrane oxygenation in pediatrics: How long did we wait?

BACKGROUND: In this study, we aimed to evaluate the duration of extracorporeal membrane oxygenation (ECMO) and its effect on outcomes. Also, we sought to identify hospital mortality predictors and determine when ECMO support began to be ineffective. METHODS: This was a single-center, retrospective cohort study conducted between January 2014 and January 2022. The prolonged ECMO (pECMO) cut-off point was accepted as 14 days. RESULTS: Thirty-one (29.2%) of 106 patients followed up with ECMO had pECMO. The mean follow-up period of the patients who underwent pECMO was 22 (range, 15-72) days, and the mean age was 75 ± 72 months. According to the results of our heterogeneous study population, life expectancy decreased dramatically towards the 21st day. Hospital mortality predictors were determined in the logistic regression analysis in all ECMO groups in our study as high Pediatric Logistic Organ Dysfunction (PELOD) two score, continuous renal replacement therapy (CRRT) use, and sepsis. The pECMO mortality was 61.2% and the overall mortality was 53.0%, with the highest mortality rate in the bridge-to-transplant group (90.9%) because of lack of organ donation in our country. CONCLUSIONS: In our study, the PELOD two score, presence of sepsis, and use of CRRT were found to be in the predictors of in-hospital ECMO mortality model. Considering the complications, in the COX regression model analysis, the factors affecting the probability of dying in patients followed under ECMO were found to be bleeding, thrombosis, and thrombocytopenia.

Hybrid extracorporeal membrane oxynegation in pediatric intensive care patients: A single center experience: More is better?

BACKGROUND: The initial extracorporeal membrane oxygenation (ECMO) configuration is inefficient for patient oxygenation and flow, but by adding a Y-connector, a third or fourth cannula can be used to support the system, which is called hybrid ECMO. METHODS: This was a single-center retrospective study consisting of patients receiving hybrid and standard ECMO in our PICU between January 2014 and January 2022. RESULTS: The median age of the 12 patients who received hybrid ECMO and were followed up with hybrid ECMO was 140 (range, 82-213) months. The total median ECMO duration of the patients who received hybrid ECMO was 23 (8-72) days, and the median follow-up time on hybrid ECMO was 18 (range, 3-46) days. The mean duration of follow-up in the PICU was 34 (range, 14-184) days. PICU length of stay was found to be statistically significant and was found to be longer in the hybrid ECMO group (p = 0.01). Eight (67%) patients died during follow-up with ECMO. Twenty-eight-day mortality was found to be statistically significant and was found to be higher in the standard ECMO group (p = 0.03). The hybrid ECMO mortality rate was 66% (decannulation from ECMO). The hybrid ECMO hospital mortality rate was 75%. The standard ECMO mortality rate was 52% (decannulation from ECMO). The standard ECMO hospital mortality rate was 65%. CONCLUSIONS: Even though hybrid ECMO use is rare, with increasing experience and new methods, more successful experience will be gained. Switching to hybrid ECMO from standard ECMO at the right time with the right technique can increase treatment success and survival.

Clinical characteristics and outcomes of continuous renal replacement therapy performed on younger children weighing up to 10 kg.

BACKGROUND: This study aimed to investigate the clinical features, modality, complications, and effecting factors on the survival of children weighing up to 10 kg who received continuous renal replacement therapy (CRRT). METHODS: This study was a retrospective observational study conducted in five pediatric intensive care units in tertiary hospitals in Turkey between January 2015 and December 2019. RESULTS: One hundred and forty-one children who underwent CRRT were enrolled in the study. The median age was 6 (range, 2-12)months, and 74 (52.5%) were male. The median weight of the patients was 6 (range, 4-8.35) kg and 52 (36.9%) weighed less than 5 kg. The most common indication for CRRT was fluid overload in 75 (53.2%) patients, and sepsis together with multiorgan failure in 62 (44%). The overall mortality was 48.2%. DISCUSSION: Despite its complexity, CRRT in children weighing less than 10 kg is a beneficial, lifesaving extracorporeal treatment modality.

Continuous Renal Replacement Therapy with Regional Citrate Anticoagulation in Children with Liver Dysfunction/Failure.

Regional citrate anticoagulation (RCA) is an option but citrate accumulation is risk and it is a giving up cause for this situation. This retrospective study was conducted in the pediatric intensive care unit (PICU) between May 2019 and April 2021. We investigated 47 patients with liver failure (LF) in our PICU, and RCA during continuous renal replacement therapy (CRRT) was applied to 10 (21.3%) of them. Half of them were male (n: 5/10), their mean age was 104.7 ± 66.20 months. Nine of them needed vasoactive support during follow-up. The most common indication for CRRT was hepatorenal syndrome (40%). There was no significant difference between liver transaminases and liver function tests before and after CRRT (p > 0.05). In terms of citrate toxicity of the patients, there was no significant difference between total calcium/ionized calcium, lactate level, pH and bicarbonate values before and after CRRT (p > 0.05). The mean total CRRT time was 110.2 ± 118.2 h, and the mean circuit lifespan was 43.8 ± 48.7 h; the mean number of circuits was 2.7 ± 2.4. Total Ca/ionized Ca >2.5 was a clinically relevant endpoint, but no patient interrupted dialysis for this cause. There was no complication about RCA. This study did not observe any adverse effects on acid-base status, transaminases, an increase in bilirubin during RCA-CRRT treatment in pediatric patients with LF. Total calcium/ionized calcium ratio, serum lactate level and prothrombin time level should be closely monitored daily in terms of citrate accumulation in this patient group.

Colchicine Poisoning Cases in a Pediatric Intensive Care Unit: A Twenty-Year Study.

OBJECTIVES: Colchicine intoxication is rare but potentially fatal. The toxic dose of colchicine is not well established; it has been reported that major toxicity starts after doses of 0.5 mg/kg. We aimed to evaluate the demographic, clinical aspects, treatments, and outcome of colchicine toxicity cases in the pediatric intensive care unit (PICU). METHODS: We collected the data of patients aged between 0 and 18 years, admitted to Ankara University Faculty of Medicine PICU for colchicine poisoning (n = 22), from October 1999 to January 2020, retrospectively. Data extracted from the cases included age, sex, chronic condition, time between intake of drug and admission to PICU, source of drug, amount of drug ingested, other drug intake, symptoms, clinical findings, cardiac involvement, laboratory results, time of stay in PICU, treatment, and outcome. RESULTS: Patients' age ranged from 7 months to 17 years. Median age was 86 months. The most common symptom at time of admission was vomiting, occurring in 13 (59%) of the patients. Two of the patients presented with change in mental status. Time between taking medication and applying to the hospital ranged from half an hour to 4 days. Medication intake of 3 of 22 patients was more than 0.5 mg/kg. One patient whose parents' best estimate of dose ingested was 0.48 mg/kg died because of the development of multiorgan failure. One patient who ingested 0.4 mg/kg of colchicine underwent plasma exchange and recovered without any complications. CONCLUSIONS: Colchicine poisoning has a high risk of mortality, and death can be seen in doses less than a single acute dose of 0.5 mg/kg. These patients need close monitoring because there is always a risk of them to require aggressive support. Prognosis is poor in patients who have rapidly developing hemodynamic failure.

Influenza Virus Associated Pediatric Acute Respiratory Distress Syndrome: Clinical Characteristics and Outcomes.

BACKGROUND AND OBJECTIVE: The aim of this multicenter retrospective study was to determine the clinical characteristics, treatment approaches and the course of pediatric acute respiratory distress syndrome (PARDS) which developed associated with the influenza virus in the 2019-20 season. METHODS: Patients included 1 month to 18 years who were diagnosed with PARDS associated with the influenza virus in the 2019-20 season. RESULTS: Sixty-seven patients were included in the study. The mean age of the patients was 64.16 ± 6.53 months, with 60% of the group <5 years. Influenza A was determined in 54 (80.5%) patients and Influenza B in 13 (19.5%). The majority of patients (73.1%) had a comorbidity. Fifty-eight (86.6%) patients were applied with invasive mechanical ventilation, Pediatric Acute Lung Injury Consensus Conference classification was mild in 5 (8.6%), moderate in 22 (37.9%) and severe in 31 (52.5%) patients. Ventilation was applied in the prone position to 40.3% of the patients, and in nonconventional modes to 24.1%. A total of 22 (33%) patients died, of which 4 had been previously healthy. Of the surviving 45 patients, 38 were discharged without support and 7 patients with a new morbidity. CONCLUSION: Both Influenza A and Influenza B cause severe PARDS with similar characteristics and at high rates. Influenza-related PARDS cause 33% mortality and 15.5% morbidity among the study group. Healthy children, especially those aged younger than 5 years, are also at risk.

The Evaluation of Transported Children to Pediatric Intensive Care Unit: Indications, Problems, and Outcomes.

OBJECTIVE: Critically ill children often require transport to tertiary centers where higher levels of care can be provided. In this study, we aimed to evaluate the reasons for transport, complications that occurred during transport, and the clinical outcomes of the patients transferred to our tertiary pediatric intensive care unit (PICU). METHODS: This retrospective study was conducted in a tertiary pediatric hospital with 250 beds and 20 tertiary PICU beds. RESULTS: During the study period, 108 patients were transferred to our PICU. The mean age was 75.0 ± 70.5 months (range, 1-211 months), and 59 were female. Most patients (82.4%) were transported by land; 17.6% were transported by air ambulance. Fourteen patients were referred for liver transplantation, and 7 patients were referred because of a need for extracorporeal membrane oxygenation support and heart transplantation or left ventricular assist device placement. Two patients were transported by air while on extracorporeal membrane oxygenation. Complications occurred in 25% of patients. CONCLUSION: Vital signs were assesed, and certain critical interventions such as intravenous fluids and respiratory support were provided more frequently during air transport, possibly due to the fact that physicians were always present during air transport. Quality improvement of transport teams and multicenter and nationwide studies on PICU transport are needed.

An Outbreak of Shiga Toxin-Positive Enteroaggregative Escherichia coli 0104:H4 Related Hemolytic Uremic Syndrome in Turkey: A Multicenter Study.

INTRODUCTION: Serious outbreaks related to Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) have been reported globally. In 2011, Germany experienced a significant outbreak of HUS caused by enteroaggregative Escherichia coli (EAEC) O104:H4 strain. Since then, no other outbreaks of this strain have been reported. This study aims to evaluate pediatric patients affected by the second documented worldwide outbreak of STEC-HUS (EAEC O104:H4 serotype) contaminating local drinking water. METHODS: Medical records of patients hospitalized in five pediatric intensive care units (PICU) diagnosed with STEC-HUS between July and September 2022 were evaluated retrospectively. RESULTS: Eighteen patients (14 girls, and 4 boys) were enrolled in the study. The median age was 7.4 [Intetquartile range (IQ) 1.3-17] years. Abdominal pain was the most common symptom (100%). The mean duration between symptom onset and development of STEC-HUS was 3 days (IQ 1-9). EAEC O104:H4 serotype was detected in the stool samples of eight patients. Neurological involvement was observed in three patients, cardiac involvement in two patients, and both in one patient. Two patients required respiratory support and dialysis was performed in 16 (88.8%) patients. Plasmapheresis was administered to two patients, and eculizumab was given to four. No mortality was reported during follow-up; the mean durations of PICU and hospital stays were 11.3 and 31.6 days, respectively. CONCLUSION: Outbreaks of HUS can have severe implications on mortality and morbidity. However, timely diagnosis and implementation of appropriate supportive care, including dialysis, respiratory support, and suitable medical treatment for eligible patients, can lead to favorable outcomes.

Extracorporeal Membrane Oxygenation after Pediatric Cardiac Surgery: A Single-Center Experience.

Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment option providing cardiopulmonary support when standard therapies prove insufficient for reversible diseases. The mean objective of this study was to evaluate our center's experience with ECMO following pediatric cardiac surgery. This retrospective study was conducted in our pediatric intensive care unit (PICU) between November 2014 and March 2021 and included patients who received ECMO following cardiac surgery. Over the 7-year period, 324 patients underwent cardiac surgery, of which 24 (7.4%) required ECMO support. Among them, 13 (54.2%) were female, with a median age of 16.0 (2.0- 208) months and a median weight of 7.0 (3.5-70) kg. The mean vasoactive inotrope score (VIS) was 53.9 ± 44.5. Atrioventricular septal defect repair was the most common surgical procedure (n = 8/24, 41.6%). The primary indication for ECMO was low cardiac output syndrome (LCOS) in 14 (58.3%) patients. The median duration of ECMO support was 6.0 (1.0-46.0) days. Nonsurvivors had significantly higher Pediatric Risk Score of Mortality (PRISM) III scores (P = .014) and VIS scores during the pre-ECMO period (P = .004). Early or late neurological complications developed in 12 (50%) patients, with significant differences in lactate levels and pH levels preECMO between those with and without neurological complications (P = .01, P = .02, respectively). We successfully decannulated 16 (66.6%) patients, with a final survival rate of 12 (50%). ECMO plays a crucial role in providing pre- and post-cardiac surgery support for children. LCOS remains the main indication, and high PRISM III and VIS scores are valuable predictors of outcomes.

Early period intensive care follow-up after liver transplantation in children: a single center experience.

BACKGROUND: Liver transplantation (LT) is a well-established, life-saving treatment for children with irreversible acute and chronic liver failure (LF). We aimed to evaluate the factors associated with morbidity and mortality in the early period of LT in children by reviewing our pediatric intensive care unit (PICU) experience. METHODS: We reviewed children`s medical records followed in the PICU after LT between May 2015-August 2021, including demographic parameters, indications for LT, operative variables, respiratory and circulatory support requirements, LT-related complications and survival. RESULTS: During this period, 40 pediatric patients who underwent LT were evaluated. LT was performed in 35 (87.5%) cases of chronic liver disease and 5 (12.5%) cases of acute liver failure. Twenty-four patients had chronic liver failure due to cholestatic liver disease. The patients` Pediatric Risk of Mortality (PRISM) III score was 18.82±SD (2-58) at PICU admission. 1-year survival was 87.5%, and overall survival was 85%. Younger age, low body weight, preoperative pediatric end-stage liver disease (PELD), and model for end-stage liver disease (MELD) values of 20 and higher were important risk factors for unfavorable outcomes after living donor liver transplantation (LDLT). These risk factors are both associated with technically more challenging vascular and bile duct reconstruction and higher complication rates, and increased mortality during the early period after LT. CONCLUSIONS: The early period of optimum PICU management in pediatric LT recipients is crucial for successful outcomes, which is also related to the patients` characteristics, disease severity scores, and surgical procedures.
