Podcast 779: Pulse Pressure in Trauma

Podcast 779: Pulse Pressure in Trauma

Contributor: Aaron Lessen, MD Educational Pearls:
  • Pulse pressure is the difference between the systolic and diastolic blood pressure, normal is about 40
  • A narrow pulse pressure is generally thought of as less than 30 mmHg which may signal peripheral vasoconstriction in response to lower blood volumes
  • 2020 study examined hypotension and narrow pulse pressure in trauma and outcomes
  • 37% of patients who were hypotensive on ED arrival had a severe injury, 22% of patients who had a narrow pulse pressure had a severe injury, and 11% of patients with normal blood pressure and normal pulse pressure had a severe injury
  • Need for thoracotomy, death, cardiac arrest, and need for other interventions was highest in the hypotensive group, the lowest in the normal blood pressure/normal pulse pressure group, and narrow pulse pressure group outcomes fell in the middle
  • Narrow pulse pressure in the setting of trauma may be a helpful vital sign to incorporate into trauma care in the ED
