Early noninvasive positive pressure ventilation and high-dose nitroglycerin provide rapid symptom relief and may reduce intubation rates in sympathetic crashing acute pulmonary edema.
Does early NIPPV and high-dose nitroglycerin improve outcomes compared to traditional management with morphine and diuretics in patients with SCAPE?
Modern management of SCAPE should prioritize early NIPPV and high-dose nitroglycerin while avoiding morphine and diuretics in the acute phase to optimize clinical outcomes.

Sympathetic crashing acute pulmonary edema (SCAPE) is a life-threatening condition caused by a sudden surge in sympathetic activity, leading to fluid redistribution, hypoxia and severe dyspnea. To summarize SCAPE diagnosis, review historical and modern pharmacological treatment regimens, and provide an evidence-based approach to medication management in the Emergency Department. Traditional use of morphine and diuretics in initial SCAPE management is discouraged due to associations with hypotension, intubation, and ICU admission. Current evidence supports early initiation of noninvasive positive pressure ventilation (NIPPV), either continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP), and high dose nitroglycerin for rapid preload and afterload reduction. The choice of NIPPV modality should be guided by equipment availability and clinician experience, as no clear advantage exists in literature. High-dose nitroglycerin, as a continuous infusion with or without bolus, has demonstrated rapid symptom relief and may reduce intubation rates. Hypotension is the most common side effect and typically resolves with small fluid boluses. Modern management of SCAPE should prioritize early NIPPV and high-dose nitroglycerin with avoidance of morphine and diuretics in the acute phase. Further studies are needed to clarify the optimal dosing strategy of nitroglycerin – bolus, infusion, or a combination approach. Rapid initiation, close monitoring and frequent titrations are essential to achieve the best clinical outcomes.
