ICU patients are weaned from sedation and mechanical ventilation through spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs). Weaning can be distressing for patients and their families. Family-led coaching could reassure patients and reduce stress for families by engaging them in patient care. This study developed and piloted a family-led coaching tool to support patients undergoing SATs/SBTs. ⋯ Family-led coaching of patients during SATs/SBTs appears to be feasible, favorably perceived by families and clinicians, and potentially associated with lower family anxiety.

Pediatric asthma is a significant cause of emergency department visits and hospital admissions. While most patients respond well to standard pharmacologic treatments, those with more severe disease frequently require noninvasive respiratory support (NRS) and adjunct therapies, or admission to an intensive care unit-a condition termed critical asthma. NRS modalities include high-flow nasal cannula (HFNC), continuous positive airway pressure (CPAP), and noninvasive ventilation (NIV) to deliver standard air-oxygen mixtures or helium-oxygen (heliox). ⋯ Despite the growing use of NRS, robust evidence supporting its efficacy in pediatric critical asthma is limited, with few published clinical trials and a heavy reliance on observational studies to inform clinical practice. This narrative review explores the current evidence, physiological rationale, practical considerations, and future research directions for the use of NRS in pediatric critical asthma. The goal is to provide clinicians with a comprehensive overview of the benefits and limitations of NRS modalities to better inform therapeutic decisions and improve patient outcomes.

Pediatric critical asthma, or formerly known as status asthmaticus, is a common pediatric condition encountered in emergency departments, hospital wards, and pediatric intensive care units. Systemic corticosteroids and inhaled bronchodilators are evidence-based, initial treatments for patients with pediatric critical asthma. If clinical symptoms do not improve, pediatric practitioners often prescribe adjunctive medications including inhaled anticholinergics, intravenous ketamine, intravenous magnesium, intravenous short acting beta 2 agonists, and intravenous methylxanthines (such as aminophylline). In this narrative review, we will summarize the current evidence and present the research gaps related to these therapies in the pediatric population.

Comparative Study
In Vitro Comparison of Aerosol Delivery in High-Frequency Assisted Airway Clearance Devices With Integrated Nebulizers.
High-frequency assisted airway clearance systems combine positive expiratory pressure or oscillatory positive airway pressure with integrated nebulizers to improve the delivery of aerosols and assist with airway clearance. This aerosol study evaluated lung delivery efficiency during positive expiratory pressure and oscillatory positive airway pressure therapy of 2 high-frequency assisted airway clearance/nebulizer systems. ⋯ The BiWaze Clear system showed greater delivery efficiency than did the Volara during positive expiratory pressure and oscillatory positive airway pressure. The high residual nebulizer dose and fugitive aerosol losses through the handset leak valve contributed to the lower delivery efficiency observed with the Volara. The nebulizer type, circuit design, and handset are important factors when targeting effective aerosol delivery to the lungs with high-frequency assisted airway clearance therapy.
