Article Synopsis
  • This study examines how cardiovascular responses (like heart rate and blood pressure) can help predict the outcomes for children with acute acquired brain injury (ABI) who are admitted to the pediatric intensive care unit (PICU).
  • The research included 72 children, where significant associations were found between conditions like tachycardia and abnormal blood pressure levels and their likelihood of mortality.
  • The findings suggest that the Poincaré SD1/SD2 ratio may be a useful tool for predicting mortality in these patients, indicating the need for larger studies to confirm these results.

The prevalence of aneurysms in children is low when compared to adults, being even rarer in the first year of life. They can be secondary to infections, traumatic brain injury, autoimmune diseases, or connective tissue diseases. Dissecting etiology is rare.

Background: Brain injury is a leading cause of morbidity and mortality in the pediatric population. Neurogenic stunned cardiomyopathy is a complication associated with several neurological conditions that can lead to worse outcomes. It presents as alterations in blood pressure, cardiac rhythm disturbances and the increase in cardiac injury biomarkers.

Background: Acute kidney injury (AKI) is associated with worse outcomes and increased morbidity and mortality in pediatric intensive care unit (PICU) patients. The renal angina index (RAI) has been proposed as an early prediction tool for AKI development.

Objectives: The objective was to evaluate outcomes of RAI-positive patients and to compare RAI performance with traditional AKI markers across different patient groups (medical/post-surgical).

Objective: This study aimed to do a literature review to prove the hypothesis that a change in autonomous nervous system regulation, more precisely a decrease in heart rate variability (HRV), is associated with a worse outcome and could be used as a prognostic factor in children with TBI.

Methods: Databases (Pubmed, World of Science and Scopus) studies were conducted from 1996 to 2017, considering HRV in children with TBI. Seven studies were analyzed.

Purpose: Heart rate variability (HRV) has been a relevant tool in the assessment of the autonomic nervous system (ANS). How autonomic control normally develops in newborns and how it is affected by gestational age (GA) is not fully understood. We aimed to review the current evidence on HRV in preterm (PT) and term neonates (TN) and investigate the relation between GA and the maturation of ANS.

Pulmonary artery sling is a rare congenital condition often associated with congenital tracheal stenosis. Untreated pulmonary sling carries a high morbidity and mortality, most of which is due to the airway and other associated anomalies rather than the aberrant artery itself. We report the case of an infant presenting progressive respiratory distress after a viral infection.

The objective of this study is to report a case of ischemic subglottic damage after a short-time intubation with a large, overinflated endotracheal tube cuff in a child. The study uses individual case report. A 6-year-old boy was admitted to the pediatric intensive care unit after a head trauma intubated with a 5.
