A 46-year-old man presented after a motor vehicle collision. He suffered abdominal injuries (liver laceration, avulsed gall bladder) which were successfully managed non-operatively. The patient remained intubated on mechanical ventilation and remained hypotensive after the injuries resolved. The patient required norepinephrine at low doses to maintain a normal blood pressure. It was noted the patient had a history of remote tricuspid valve replacement. A bedside echocardiogram was then performed to determine the etiology of the patient’s persistent hypotension after hypovolemia had been excluded.

Ultrasound for Critical Care Physicians: Hungry Heart

A 31-year-old incarcerated man with a past medical history of intravenous drug use and hepatitis C, presented with a one week history of dry, non-productive cough, orthopnea and exertional dyspnea. He denied current intravenous drug use, and endorsed that the last time he used was before he was incarcerated over 3 years ago, his last tattoo was in prison, 6 months prior. He was found to have an oxygen saturation of 77% on room air, fever of 40º C, heart rate of 114 bpm, and blood pressure of 80/50 mmHg. The patient had a leukocytosis of 14 x109/L, and a chest x-ray demonstrating patchy airspace disease. Blood cultures were sent and he was treated with antibiotics and vasopressors for septic shock. The patient was intubated for acute hypoxemic respiratory failure secondary to multifocal pneumonia. A bedside transthoracic echocardiogram was performed.
