RESUMEN
BACKGROUND & AIM: Fast-track or enhanced recovery after surgery (ERAS) is a care pathway for surgical patients based on a multidisciplinary team approach aimed at optimising recovery without increasing risk with protocols based on scientific evidence, which is monitored continuously to ensure compliance and improvement. These protocols have been shown to reduce the duration of postoperative mechanical ventilation and intensive care unit (ICU) length of stay (LOS) following paediatric cardiac surgery. We present the first structured implementation of ERAS in paediatric cardiac surgery in Australia. METHODS: All patients enrolled in the ERAS pathway between October 2019 and July 2023 were identified. Demographic and perioperative data were collected retrospectively from hospital records for patients operated before June 2021 and prospectively from June 2021. A control group (non-ERAS) was identified using propensity matching from patients who underwent similar procedures and were not enrolled in the ERAS pathway (prior to October 2019). Patients were matched for age, weight, and comprehensive Aristotle score. Outcomes of interest were duration of postoperative mechanical ventilation, ICU LOS, readmission to the ICU, hospital LOS, cardiac reintervention rate, postoperative complication rate, and number of 30-day readmissions. RESULTS: Of 1,084 patients who underwent cardiac surgery during the study period (October 2019-July 2023), 121 patients (11.2%) followed the ERAS pathway. The median age at the time of surgery was 4.8 years (interquartile range [IQR] 2.8-8.8 years). The most common procedure was the closure of atrial septal defect (n=58, 47.9%). The median cardiopulmonary bypass and cross-clamp times were 40 min (IQR 28-53.5 minutes) and 24.5 min (IQR 13-34 minutes) respectively. The majority were extubated in the operating theatre (n=108, 89.3%). The median ICU and hospital LOS were 4.5 hrs (IQR 4.1-5.6 hours) and 4 days (IQR 4-5 days) respectively. None of the patients required readmission to the ICU within 24 hrs of discharge from the ICU. Three (3) patients (2.5%) required reintervention. When compared with the non-ERAS group, the duration of postoperative mechanical ventilation, ICU and hospital LOS were significantly lower in the ERAS group. There was no significant difference in the ICU readmission rate, reintervention rate, complication rate, and number of 30-day readmissions between both groups. CONCLUSIONS: ERAS after paediatric cardiac surgery is feasible and safe in select patients with low preoperative risk. This pathway reduces the duration of postoperative mechanical ventilation, ICU and hospital LOS without increasing risks, enabling the optimisation of resources.

BACKGROUND: Flexible fibreoptic bronchoscopy (FFB) has the potential to enhance diagnostic capabilities and improve pulmonary function in children on extracorporeal membrane oxygenation (ECMO). OBJECTIVES: The objective of this study was to evaluate the benefits (clinical, radiological, and microbiological) of FFB and assess associated complications in children on ECMO. METHODS: We conducted a single-centre retrospective observational cohort study in a tertiary paediatric intensive care unit. All FFB episodes performed during the study period on children aged 0-18 years on ECMO were included. RESULTS: Out of the 155 children who received ECMO, 36 (23%) underwent a total of 92 episodes of FFB. FFB provided anatomical and pathological information in 53% (19/36) of cases and proved beneficial in clearing the airways in 62% (54/87) of the episodes. Overall, patients exhibited transient increases in ECMO and mechanical ventilation support 1 h post FFB in 14% (13/92) and 9.7% (9/92) episodes, respectively. At 6 h, the mean fraction of inspired oxygen on the mechanical ventilator was lower (0.46 [±0.21] vs 0.53 [±0.21] p < 0.01), with no change in mean airway pressure. Similarly, compared to pre-FFB, the fraction of inspired oxygen on the mechanical ventilator on ECMO was lower at 6 h and 24 h (0.65 [±0.25] vs 0.71 [±0.23] p < 0.01 and 0.006, respectively), with no significant change in the sweep gas flow and ECMO flow. The radiological imaging indicated improved or stable findings in 91% (83/91) of FFB episodes. FFB contributed to the identification of new and previously unknown microbiological information in 75% (27/36) of the patients. The incidence of major complications was 7.6%. Minor self-resolving bleeding occurred in 25% (23/92) episodes, and major bleeding occurred in two episodes, with a total of 10 episodes needing blood product transfusion. CONCLUSIONS: FFB is a valuable adjunct in managing children with severe respiratory failure on ECMO, offering clinical benefits with a low rate of major complications. Further studies should aim to develop a consensus approach encompassing criteria and clinical management around FFB in patients on ECMO.
RESUMEN
BACKGROUND/AIM: The objective of this study was to describe current surveillance platforms which support routine quality measurement in paediatric critical care. METHOD: Scoping review. The search strategy consisted of a traditional database and grey literature search as well as expert consultation. Surveillance platforms were eligible for inclusion if they collected measures of quality in critically ill children. RESULTS: The search strategy identified 21 surveillance platforms, collecting 57 unique outcome (70%), process (23%), and structural (7%) quality measures. Hospital-associated infections were the most commonly collected outcome measure across all platforms (n = 11; 52%). In general, case definitions were not harmonised across platforms, with the exception of nationally mandated hospital-associated infections (e.g., central line-associated blood stream infection). Data collection relied on manual coding. Platforms typically did not provide an evidence-based rationale for measures collected, with no identifiable reports of co-designed, consensus-derived measures or consumer involvement in measure selection or prioritisation. CONCLUSIONS: Quality measurement in critically ill children lacks uniformity in definition which limits local and international benchmarking. Current surveillance activities for critically ill children focus heavily on outcome measurement, with process, structural, and patient-reported measures largely overlooked. Long-term outcome measures were not routinely collected. Harmonisation of paediatric intensive care unit quality measures is needed and can be achieved using prioritisation and consensus/co-design methods.

OBJECTIVES: Milrinone is an inodilator widely used in the postoperative management of children undergoing cardiac surgery. The literature supporting its inotropic effect is sparse. We sought to study the effect of milrinone on the vasculature and its effects on the ventricular function using wave intensity analysis. We also intended to evaluate the feasibility of using wave intensity analysis by the bedside. DESIGN: prospective single-center observational study. SETTING: PICU of a tertiary children's hospital. PATIENTS: Children (< 18 yr) admitted to PICU following cardiac surgery who required to be commenced on a milrinone infusion. INTERVENTIONS: Echocardiography and Doppler ultrasound assessments for wave intensity analysis were performed prior to commencing milrinone and 4-6 hours after milrinone infusion. MEASUREMENTS AND MAIN RESULTS: Wave intensity analysis was successfully performed and analyzed in 15 of 16 patients (94%). We identified three waves-a forward compression wave, backward compression wave, and forward decompression wave. The waves were described with their cumulative intensity and wave-related pressure change. There was a 26% reduction in backward compression wave cumulative intensity following the introduction of milrinone. Other variables (backward compression wave cumulative intensity/forward compression wave cumulative intensity ratio, backward compression wave wave-related pressure change, backward compression wave wave-related pressure change/forward compression wave wave-related pressure change ratio) consistent with vasodilation also decreased after milrinone. It also decreased the vascular wavespeed by 7.1% and increased the distensibility of the vessels by 14.6%. However, it did not increase forward compression wave cumulative intensity, a variable indicating the systolic force generated by the ventricle. Forward decompression wave cumulative intensity indicating ventricular early diastolic relaxation also did not change. CONCLUSIONS: In a cohort of children recovering in PICU after having undergone cardiac surgery, we found that milrinone acted as a vasodilator but did not demonstrate an improvement in the contractility or an improved relaxation of the left ventricle as assessed by wave intensity analysis. We were able to demonstrate the feasibility and utility of wave intensity analysis to further understand ventriculo-vascular interactions in an intensive care setting.

Pediatric index of mortality (PIM)-2 and PIM3 are the most recent versions of severity of illness scoring generated from a pediatric intensive care unit (PICU) population in Australia and the United Kingdom. The authors present a single-center evaluation of a performance of these scores in a PICU in Colombia. PIM3 seemed to demonstrate a marginally better performance at predicting mortality, although the discrimination was similar for both scores. Incorporation of this approach to the rest of the units throughout the country would help with benchmarking PICU performance. HOW TO CITE THIS ARTICLE: Rahiman S.

RESUMEN
OBJECTIVE: To identify the most appropriate timeframe for Pediatric Index of Mortality-2 data collection in patients transported to PICUs by specialist teams. DESIGN: Retrospective cohort study. SETTING: A regional PICU transport team in London, United Kingdom. PATIENTS: Children admitted for intensive care to a tertiary children's hospital PICU following transport by a PICU transport team between January 1, 2007, and December 31, 2008. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data on case mix and outcome from children transferred to the tertiary PICU during the study period were analyzed. The "standard" timeframe used in calculating Pediatric Index of Mortality-2 was compared with Pediatric Index of Mortality-2 calculated using data from two other 1-hour timeframes (during "retrieval" and during "admission"). A total of 759 transported admissions were studied. Eighty-three children died (mortality rate, 10.9%). Data were missing in up to 42.7% of admissions for some Pediatric Index of Mortality-2 variables from transport. However, missing data persisted even after the first hour of PICU admission in most cases. There was significant improvement in some physiological variables following transport (p < 0.01), but Pediatric Index of Mortality-2 did not change significantly. Pediatric Index of Mortality-2 from all three timeframes exhibited good discrimination (area under the receiver-operating characteristic curve ≥ 0.77). Calibration across deciles of mortality risk was poor for the "admission" Pediatric Index of Mortality-2 (Hosmer-Lemeshow goodness-of-fit test p = 0.04) but good for the other two calculated Pediatric Index of Mortality-2 models (p > 0.20). CONCLUSIONS: The findings of our single-center study do not support the need for different timeframes for Pediatric Index of Mortality-2 data collection in transported and direct PICU admissions. Uniformity in scoring procedure may simplify data collection and improve data quality.

OBJECTIVES: The aim of this study was to assess the early outcomes and risk factors of paediatric patients requiring extracorporeal membrane oxygenation after cardiac surgery (post-cardiotomy). METHODS: Retrospective binational cohort study from the Australia and New Zealand Congenital Outcomes Registry for Surgery database. All patients younger than 18 years of age who underwent a paediatric cardiac surgical procedure from 1 January 2013 to 31 December 2021 and required post-cardiotomy extracorporeal membrane oxygenation (PC-ECMO) in the same hospital admission were included in the study. RESULTS: Of the 12 290 patients included in the study, 376 patients required post-cardiotomy ECMO (3%). Amongst these patients, hospital mortality was 35.6% and two-thirds of patients experienced a major complication. Hypoplastic left heart syndrome was the most common diagnosis (17%). The Norwood procedure and modified Blalock-Taussig shunts had the highest incidence of requiring PC-ECMO (odds ratio of 10 and 6.8 respectively). Predictors of hospital mortality after PC-ECMO included single-ventricle physiology, intracranial haemorrhage and chylothorax. CONCLUSIONS: In the current era, one-third of patients who required PC-ECMO after paediatric cardiac surgery in Australia and New Zealand did not survive to hospital discharge. The Norwood procedure and isolated modified Blalock-Taussig shunt had the highest incidence of requiring PC-ECMO. Patients undergoing the Norwood procedure had the highest mortality (48%). Two-thirds of patients on PC-ECMO developed a major complication.

Introduction: Monitoring healthcare quality is challenging in paediatric critical care due to measure variability, data collection burden, and uncertainty regarding consumer and clinician priorities. Objective: We sought to establish a core quality measure set that (i) is meaningful to consumers and clinicians and (ii) promotes alignment of measure use and collection across paediatric critical care. Design: We conducted a multi-stakeholder Delphi study with embedded consumer prioritisation survey. The Delphi involved two surveys, followed by a consensus meeting. Triangulation methods were used to integrate survey findings prior tobefore the consensus meeting. In the consensus panel, broad agreement was reached on a core measure set, and recommendations were made for future measurement directions in paediatric critical care. Setting and participants: Australian and New Zealand paediatric critical care survivors (aged >18 years) and families were invited to rank measure priorities in an online survey distributed via social media and consumer groups. A concurrent Delphi study was undertaken with paediatric critical care clinicians, policy makers, and a consumer representative. Interventions: None. Main outcome measures: Priorities for quality measures. Results: Respondents to the consumer survey (n = 117) identified (i) nurse-patient ratios; (ii) visible patient goals; and (iii) long-term follow-up as their quality measure priorities. In the Delphi process, clinicians (Round 1 n = 191; Round 2 n = 117 [61% retention]; Round 3 n = 14) and a consumer representative reached broad agreement on a 51-item (61% of 83 initial measures) core measure set. Clinician priorities were (i) nurse-patient ratio; (ii) staff turnover; and (iii) long term-follow up. Measure feasibility was rated low due to a perceived lack of standardised case definitions or data collection burden. Five recommendations were generated. Conclusions: We defined a 51-item core measurement set for paediatric critical care, aligned with clinician and consumer priorities. Next steps are implementation and methodological evaluation in quality programs, and where appropriate, retirement of redundant measures.
RESUMEN
INTRODUCTION: Intravenous fluid therapy is the most common intervention in critically ill children. There is an increasing body of evidence questioning the safety of high-volume intravenous fluid administration in these patients. To date, the optimal fluid management strategy remains unclear. We aimed to test the feasibility of a pragmatic randomised controlled trial comparing a restrictive with a standard (liberal) fluid management strategy in critically ill children. METHODS AND ANALYSIS: Multicentre, binational pilot, randomised, controlled, open-label, pragmatic trial. Patients <18 years admitted to paediatric intensive care unit and mechanically ventilated at the time of screening are eligible. Patients with tumour lysis syndrome, diabetic ketoacidosis or postorgan transplant are excluded. INTERVENTIONS: 1:1 random assignment of 154 individual patients into two groups-restrictive versus standard, liberal, fluid strategy-stratified by primary diagnosis (cardiac/non-cardiac). The intervention consists of a restrictive fluid bundle, including lower maintenance fluid allowance, limiting fluid boluses, reducing volumes of drug delivery and initiating diuretics or peritoneal dialysis earlier. The intervention is applied for 48 hours postrandomisation or until discharge (whichever is earlier). ENDPOINTS: The number of patients recruited per month and proportion of recruited to eligible patients are feasibility endpoints. New-onset acute kidney injury and the incidence of clinically relevant central venous thrombosis are safety endpoints. Fluid balance at 48 hours after randomisation is the efficacy endpoint. Survival free of paediatric intensive care censored at 28 days is the clinical endpoint. ETHICS AND DISSEMINATION: Ethics approval was gained from the Children's Health Queensland Human Research Ethics Committee (HREC/21/QCHQ/77514, date: 1 September 2021), and University of Zurich (2021-02447, date: 17 March 2023). The trial is registered with the Australia New Zealand Clinical Trials Registry (ACTRN12621001311842). Open-access publication in high impact peer-reviewed journals will be sought. Modern information dissemination strategies will also be used including social media to disseminate the outcomes of the study. TRIAL REGISTRATION NUMBER: ACTRN12621001311842. PROTOCOL VERSION/DATE: V5/23 May 2023.

INTRODUCTION: Peripheral intravenous catheters (PIVCs) frequently fail during therapy administration, resulting in infusates pooling in the surrounding tissue. These extravasation injuries can cause significant pain, tissue destruction and scarring. ivWatch is a biosensor that uses visible and near-infrared light to measure tissue changes surrounding the PIVC and alert clinicians when extravasation may occur. The effectiveness of ivWatch, in comparison to clinical observation, in decreasing injury severity is unknown. The present study aims to investigate whether using ivWatch may potentially detect injury earlier and decrease the severity of PIVC extravasation injuries. METHODS AND ANALYSIS: A single centre, parallel group, open-label superiority randomised controlled trial comparing (a) standard care (clinical observation) to (b) ivWatch monitoring in addition to standard care, to decrease the severity of extravasation injuries. 200 children with PIVCs inserted in the distal half of the limb, receiving intermediate-risk to high-risk infusates for ≥24 hours, will be consecutively recruited at a paediatric intensive care unit in Queensland, Australia. The primary outcome is extravasation severity, measured by the Cincinnati Children's Extravasation Harm Scale. Secondary outcomes include severity assessed with three-dimensional camera imaging, extravasation volume, treatment sequelae, the number of PIVCs used and dwell time, quality of life and healthcare costs. The between treatment difference in extravasation severity will be compared using ordinal logistic regression, with the treatment group included as the main effect, and reported with corresponding 95% CIs. Estimates of value will be presented as net monetary benefits and cost per reduction in extravasation injury severity, both presented with corresponding 95% credible intervals. ETHICS AND DISSEMINATION: This study received approval from the Children's Health Queensland Hospital and Health Service Human Research Ethics Committee (HREC) (reference number: HREC/20/QCHQ/60867) and the Griffith University HREC (reference number: 2020/310) and will be disseminated via peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: ACTRN12620000317998.

BACKGROUND: Patients with severe portopulmonary hypertension (PoPH) responsive to medical therapy may be considered for liver transplantation. We present a case of extracorporeal membrane oxygenation (ECMO) resuscitation for PoPH crisis in a child following liver transplantation (LT), and review the literature on management of this challenging setting. CASE REPORT: A 7-year-old girl, with previous Kasai portoenterostomy and subsequent severe PoPH responsive to pulmonary vasodilator therapy, underwent orthotopic LT. Five days following surgery, she had an asystolic arrest with suprasystemic pulmonary hypertension, and was resuscitated with ECMO therapy. Multi-modal strategies included sildenafil, ambrisentan, nitric oxide, intravenous Epoprostenol infusion, levosimendan, and atrial septostomy. Ten days after her LT, exploration for bleeding was necessary following abdominal drain removal. By 10 days of ECMO support, she was reviewed and considered for lung transplantation. Unfortunately, she deteriorated precipitously with abdominal compartment syndrome and multi-organ failure; sadly, life support was withdrawn 23 days after transplantation. DISCUSSION: Patients with severe PoPH may need combined thoracic organ and liver transplantation either at single or serial events. Case reports on ECMO use include resuscitation after massive pulmonary embolism during liver transplantation, bridge until the goal of vasodilatory therapy was reached in worsening PoPH following LT, and bridge to lung or repeat liver transplantation for severe pulmonary hypertension. CONCLUSIONS: ECMO resuscitation and support may be deployed as rescue therapy around the period of liver transplantation. We highlight the importance of patient selection and high risk of complications during ECMO therapy as a bridge to PoPH control.
