Status Asthmaticus and Central Herniation: A Case for Multidisciplinary Critical Care

Area of Science:

• Critical Care Medicine
• Pulmonology
• Neurology

Background:

• Acute respiratory syncytial virus (RSV) infection can trigger severe asthma exacerbations.
• Permissive hypercapnia is a ventilation strategy used in status asthmaticus.
• Managing patients with co-existing respiratory and neurological compromise presents unique challenges.

Observation:

• A 24-year-old woman with asthma developed acute status asthmaticus due to RSV infection.
• Ventilation was complicated by auto-positive end-expiratory pressure and high pressures.
• Cerebral edema with central herniation was observed on hospital day 2, indicated by anisocoria.

Findings:

• Difficult ventilation and permissive hypercapnia contributed to severe cerebral edema.
• The patient required comanagement by neurology and medical/pulmonary intensivists.
• Balancing treatment for status asthmaticus and cerebral edema was critical.

Implications:

• This case underscores the critical need to balance conflicting physiological requirements in critically ill patients.
• Effective interdisciplinary collaboration is essential for managing complex cases with dual organ system involvement.
• Understanding the interplay between respiratory mechanics, hypercapnia, and cerebral edema is vital for optimizing patient outcomes.
