Podcast 723: Nitro Drip in Flash Pulmonary Edema

Contributor: Alec Coston, MD

Educational Pearls:

• Flash pulmonary edema or Sympathetic Crash Acute Pulmonary Edema (SCAPE) is a severe illness that requires aggressive treatment
• Often in patients with heart failure and a sympathetic surge increasing heart rate, decreased diastolic filling, increased preload, and increased afterload causing pulmonary edema
• Clinical diagnosis: acute onset diaphoresis and respiratory distress, hypoxia and tachypnea on exam
• Bedside lung ultrasound will demonstrate B-lines, indicative of pulmonary edema
• Treatment is nitroglycerin and BiPAP
• Nitroglycerin drip can be started at 80 micrograms/minute, which is similar to the dose delivered by sublingual nitroglycerin
