Objectives: Despite the recommendation for lung-protective mechanical ventilation (LPMV) in pediatric acute respiratory distress syndrome (PARDS), there is a lack of robust supporting data and variable adherence in clinical practice. This study evaluates the impact of an LPMV protocol vs. standard care and adherence to LPMV elements on mortality.

Background As point-of-care ultrasound (POCUS) has gained popularity, some educational guidelines have been developed. However, in Vietnam, no training course in pediatric POCUS has yet been developed. This was challenging, especially during the COVID-19 pandemic.

Melioidosis is reported to cause a high fatality rate in children, even in the absence of risk factors for disease. The aim of this study was to identify characteristics of fatal pediatric melioidosis infection. We performed a retrospective analysis of children aged < 15 years with culture-confirmed melioidosis admitted to Bintulu Hospital in Sarawak, Malaysian Borneo, from January 2011 to December 2020.

The Surviving Sepsis Campaign International Guidelines for the Management of Septic Shock and Sepsis-associated Organ Dysfunction in Children was released in 2020 and is intended for use in all global settings that care for children with sepsis. However, practitioners managing children with sep sis in resource-limited settings (RLS) face several challenges and disease patterns not experienced by those in resource-rich settings. Based upon our collective experience from RLS, we aimed to reflect on the difficulties of implementing the international guidelines.

Abdominal pain is one of the most common presenting complaints encountered in the pediatric emergency department. The use of point-of-care ultrasonography by emergency physicians has been shown to expedite the diagnosis of a large variety of conditions and can be used to accurately identify intra-abdominal pathology in children. We describe the case of a pediatric patient who presented to the pediatric emergency department with acute abdominal pain, in whom point-of-care ultrasonography helped expedite the diagnosis of acute portal vein thrombosis and liver abscess.

Melioidosis is an infectious disease most commonly found in places with tropical climates. Definitive diagnosis can be confirmed by culture or pathological results of blood or infected organ. However, imaging study is helpful in providing early provisional diagnosis and guiding therapy.

Background: Haemoptysis is an uncommon presenting symptom in children and is usually caused by acute lower respiratory tract infection or foreign body aspiration. We report a rare case of right unilateral pulmonary vein atresia (PVA) as the underlying aetiology of recurrent haemoptysis in a child.

Case Presentation: A 4 years old girl presented with history of recurrent haemoptysis.

Background: High-frequency oscillatory ventilation (HFOV) use was associated with greater mortality in adult acute respiratory distress syndrome (ARDS). Nevertheless, HFOV is still frequently used as rescue therapy in paediatric acute respiratory distress syndrome (PARDS). In view of the limited evidence for HFOV in PARDS and evidence demonstrating harm in adult patients with ARDS, we hypothesized that HFOV use compared to other modes of mechanical ventilation is associated with increased mortality in PARDS.

Point-of-care ultrasound is currently widely used across the landscape of pediatric care. Ultrasound machines are now smaller, are easier to use, and have much improved image quality. They have become common in emergency departments, ICUs, inpatient wards, and outpatient clinics.

Introduction: Evidence supporting non-invasive ventilation (NIV) in paediatric acute respiratory distress syndrome (PARDS) remains sparse. We aimed to describe characteristics of patients with PARDS supported with NIV and risk factors for NIV failure.

Materials And Methods: This is a multicentre retrospective study.

Article Synopsis
  • - The study focuses on intravenous colistin use in pediatric patients, highlighting the lack of detailed pharmacological data to inform dosage regimens despite reliance on adult dosage guidelines from the FDA and EMA.
  • - Five pediatric patients were treated with colistimethate, with findings indicating that their plasma colistin levels varied significantly, even with a standard dose, suggesting that current dosing recommendations may not be adequate for this age group.
  • - The research concludes that renal function plays a crucial role in how colistin is processed in the body, indicating that the dosing guidelines set by regulatory bodies may need to be reconsidered to better suit pediatric patients.

Article Synopsis
  • - This study aimed to analyze and compare the characteristics, risk factors for mortality, and outcomes of extrapulmonary versus pulmonary pediatric acute respiratory distress syndrome (ARDS) in mechanically ventilated children across ten PICUs in Asia from 2009 to 2015.
  • - A total of 307 patients were examined, with 41 classified as having extrapulmonary ARDS (primarily caused by sepsis) and 266 with pulmonary ARDS (primarily caused by pneumonia). The extrapulmonary group was found to be older and had more severe health issues at admission.
  • - The primary focus of the analysis was the mortality rate in the Pediatric Intensive Care Unit (PICU), with methods such as Cox proportional hazard regression used to identify

Objectives: The Pediatric Acute Lung Injury Consensus Conference developed a pediatric specific definition for acute respiratory distress syndrome (PARDS). In this definition, severity of lung disease is stratified into mild, moderate, and severe groups. We aim to describe the epidemiology of patients with PARDS across Asia and evaluate whether the Pediatric Acute Lung Injury Consensus Conference risk stratification accurately predicts outcome in PARDS.

Background And Objectives: Current practices and available resources for nutrition therapy in paediatric intensive care units (PICUs) in the Asia Pacific-Middle East region are expected to differ from western countries. Existing guidelines for nutrition management in critically ill children may not be directly applicable in this region. This paper outlines consensus statements developed by the Asia Pacific-Middle East Consensus Working Group on Nutrition Therapy in the Paediatric Critical Care Environment.
