The patients general condition has been deteriorating, the doctors looking
after her have observed that the dose of inotropic drugs needed to maintain
the target blood pressure has been increasing, and when the drugs are briefly
discontinued there is a precipitous fall in blood pressure. The urinary output
has fallen to 20 ml per hour and the base deficit is increasing. She has
received 3 doses of broad spectrum antibiotics for an infiltrate noted on the
CXR.
Would any further investigations be helpful?
