Prone Ventilation in ARDS

ICM Case SummariesLeave a comment

An 63 year old woman with a history of bronchiectasis required intubation for a community acquired pneumonia. Several days into her ICU admission she developed a rapid worsening in her oxygenation and new bilateral pulmonary infiltrates. She also required increasing vasopressor support and began to develop multiorgan failure. She was paralysed and ventilated with inverse ratios but remained profoundly hypoxic. She was proned with no effect on oxygenation. She was commenced on inhaled nitric oxide with no effect. She continued to rapidly deteriorate and died shortly after.

Vasopressin for Adults with Septic Shock

ICM Case SummariesLeave a comment

A 70 year old man with known prostatic malignancy and stage III chronic kidney disease developed fevers, left flank pain, urinary frequency and confusion. He deteriorated rapidly in ED becoming hypotensive and drowsy. He had a lactic acidosis. CT abdomen was showed left hydronephrosis and hydroureter and was suggestive of an infected obstructed kidney. During the scan he became peri-arrest and was intubated. There was a logistical delay in achieving nephrostomy, and he was requiring escalating levels of noradrenaline. Vasopressin was commenced in order to maintain his mean arterial pressure and reduce the noradrenaline requirement from 0.8mcg/kg/min. Nephrostomy was achieved around 12 hours later and he subsequently made a full recovery.
