Status asthmaticus is a frequent cause of admission to a pediatric intensive care unit. Prompt assessment and aggressive treatment are critical. First-line or conventional treatment includes supplemental oxygen, aerosolized albuterol, and corticosteroids. There are several second-line treatments available; however, few comparative studies have been performed and in the absence of good evidence-based treatments, the use of these therapies is highly variable and dependent on local practice and provider preference. In this article the pathophysiology and treatment of status asthmaticus is discussed, and the literature regarding second-line treatments is critically assessed to apply an evidence basis to the treatment of this severe disease.

Article Synopsis
- The study investigates the practice of withholding oral nutrition from children with critical asthma receiving continuous albuterol in a pediatric ICU, aiming to determine its safety and effects on respiratory failure.
- A retrospective analysis was conducted with 36 cases (children receiving nutrition) and 72 matched controls (children not receiving nutrition), focusing on outcomes like aspiration-related respiratory failure and the duration of albuterol treatment.
- Findings indicated no respiratory failure events in either group, with those receiving nutrition having longer albuterol treatment durations but similar outcomes in terms of length of stay and mortality, suggesting that withholding nutrition may not be necessary.

Background: Current knowledge of the impact of socioeconomic factors on the risk of admission to the pediatric intensive care unit (PICU) for asthma is limited. Using composite measures of social vulnerability-Social Vulnerability Index (SVI) and Child Opportunity Index (COI) 2.0-we compared patients admitted for status asthmaticus to the PICU and pediatric ward at Children's Hospital Los Angeles (CHLA).

To compare deprescribing rates of stress ulcer prophylaxis (SUP) between children receiving "usual-dose" (<4 mg/kg/day methylprednisolone equivalents) versus "high-dose" (≥4 mg/kg/day methylprednisolone equivalents) corticosteroids for status asthmaticus in the pediatric intensive care unit (PICU). This retrospective, cohort study included children <18 years of age receiving corticosteroids for status asthmaticus and SUP from 1/1/2017 to 6/31/2022. The primary objective was to compare the number of children that were deprescribed SUP following transition from the PICU to the floor and at hospital discharge between groups.
