Severe asthma exacerbations remain a major cause of pediatric intensive care unit (PICU) admissions, particularly in early childhood. To describe the demographic characteristics, clinical features, management strategies, and short-term outcomes of children admitted to the PICU with severe acute asthma exacerbations. A retrospective descriptive study was conducted of pediatric patients aged 1-14 years with severe acute asthma requiring PICU admission at King Salman Medical City, Madinah, Saudi Arabia (January 2023-October 2024). A total of 73 patients were included. Data included demographics, risk factors, medical history, clinical presentation, management, and outcomes. The mean patient age was 4.6 years, with most (57.5%) aged 1-5 years. Males comprised 56.2% of cases. WHO BMI-for-age z-score assessment revealed a bimodal nutritional distribution: 27.9% of patients were underweight, including 20.6% with severe underweight, while 29.4% were overweight or obese; 42.6% had normal nutritional status. Severe undernutrition was concentrated in the 1-5-year age group, whereas obesity predominated in the 6-10-year age group.

Abstract
Severe asthma exacerbations remain a major cause of pediatric intensive care unit (PICU) admissions, particularly in early childhood. To describe the demographic characteristics, clinical features, management strategies, and short-term outcomes of children admitted to the PICU with severe acute asthma exacerbations. A retrospective descriptive study was conducted of pediatric patients aged 1-14 years with severe acute asthma requiring PICU admission at King Salman Medical City, Madinah, Saudi Arabia (January 2023-October 2024). A total of 73 patients were included. Data included demographics, risk factors, medical history, clinical presentation, management, and outcomes. The mean patient age was 4.6 years, with most (57.5%) aged 1-5 years. Males comprised 56.2% of cases. WHO BMI-for-age z-score assessment revealed a bimodal nutritional distribution: 27.9% of patients were underweight, including 20.6% with severe underweight, while 29.4% were overweight or obese; 42.6% had normal nutritional status. Severe undernutrition was concentrated in the 1-5-year age group, whereas obesity predominated in the 6-10-year age group. A family history of asthma was noted in 54.8% of patients; 16.4% had prior COVID-19 infection. Early symptom onset and delayed diagnosis were common. Poor asthma control was documented in 60.3%, with low medication adherence (9.6%) and limited aerochamber use (13.7%). The most frequent presenting symptoms were dyspnea, cough, and wheezing. Management followed evidence-based protocols: systemic corticosteroids and bronchodilators were first-line therapies. The mean PICU stay was 3.1 days and the mean hospital stay was 8.1 days. No mortality or major complications occurred; 93.2% of patients were discharged in good health. Severe pediatric asthma requiring PICU admission is associated with early symptom onset, a bimodal pattern of nutritional risk encompassing both undernutrition and overweight/obesity, family history of asthma, and inadequate outpatient management. These descriptive findings highlight the need for age-adjusted nutritional screening, enhanced medication adherence support, and targeted outpatient education to reduce avoidable PICU admissions.
