Background: The aim of this study is the evaluation of a closed-loop oxygen control system in pediatric patients undergoing invasive mechanical ventilation (IMV).

Methods: Cross-over, multicenter, randomized, single-blind clinical trial. Patients between the ages of 1 month and 18 years who were undergoing IMV therapy for acute hypoxemic respiratory failure (AHRF) were assigned at random to either begin with a 2-hour period of closed-loop oxygen control or manual oxygen titrations.

Background: In pediatric intensive care units, extubation failure following invasive mechanical ventilation poses significant health risks. Determining readiness for extubation in children can minimize associated morbidity and mortality. This study investigates the potential role of renal near-infrared spectroscopy (RrSO2) in predicting extubation failure in pediatric patients.

Article Synopsis
  • The study investigates multisystem inflammatory syndrome in children (MISC) related to COVID-19, focusing on comparing clinical and laboratory characteristics of children hospitalized in ICU versus those who were not.
  • Conducted from June 2021 to January 2022, the observational study included 601 patients, with 157 requiring ICU care, revealing significant differences in demographics, lab results, and disease features.
  • Key findings showed that older age groups and higher levels of certain inflammatory markers increased the likelihood of ICU admission, highlighting the severe impact of MISC on children's health.

Introduction: Malnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.

Background: Hyperlactatemia is a common finding in critically ill patients and has significant prognostic implications. However, a single lactate measurement has not been correlated to mortality consistently. In this study, we aimed to correlate the clinical efficacy of lactate clearance for the prediction of mortality in pediatric intensive care unit patients.

Background: We assessed the effect of a closed-loop oxygen control system in pediatric patients receiving high-flow nasal oxygen therapy (HFNO).

Methods: A multicentre, single-blinded, randomized, and cross-over study. Patients aged between 1 month and 18 years of age receiving HFNO for acute hypoxemic respiratory failure (AHRF) were randomly assigned to start with a 2-h period of closed-loop oxygen control or a 2-h period of manual oxygen titrations, after which the patient switched to the alternative therapy.

Objective: The aim of this study was to determine the association between the use of intravenous N-acetylcysteine (NAC) and hepatic healing in pediatric intensive care unit (PICU) patients with non-acetaminophen-induced hepatic injury, except for acute liver failure.

Methods: The data of patients who received intravenous NAC as adjuvant therapy for transaminase levels more than sixfold normal values during their PICU stay between 2010 and 2014 were retrospectively collected from the medical records database. The patients who did not receive NAC with elevated transaminase levels during their PICU stay between 2014 and 2018 were also collected as the standard of care (SOC) cohort.

Background: Central line-associated bloodstream infection is one of the four primary health-care-associated infections applicable to pediatric intensive care units defined by The Centers for Disease Control and Prevention. According to current guidelines, it is essential to flush vascular access devices before each infusion to assess catheter function and prevent catheter-related complications.

Objective: This prospective trial aimed to assess the potential differences between pre-filled and manually prepared saline syringe use during vascular access device management in a pediatric intensive care unit.
