SAH and pulmonary edema..think of Diuresis


Delayed cerebral ischemia (DCI) is the most common cause of secondary neurologic injury in patients with aneurysmal subarachnoid hemorrhage (SAH).

Intravascular volume depletion is one of several factors thought to cause, or worsen, DCI.

Pulmonary edema frequently occurs in patients with SAH.

A recent study in patients with SAH and pulmonary edema demonstrated that many were not volume overloaded.  In fact, many were intravascularly volume depleted.

Think twice about aggressive diuresis in patients with SAH and pulmonary edema, as this may exacerbate volume depletion and may worsen DCI.

Driving Pressure in ARDS: A new concept!

Driving Pressure and Survival in the Acute Respiratory Distress Syndrome Marcelo B.P. Amato, M.D., Maureen O. Meade, M.D., Arthur S. Slutsky, M.D., Laurent Brochard, M.D., Eduardo L.V. Costa, M.D., David A. Schoenfeld, Ph.D., Thomas E. Stewart, M.D., Matthias Briel, M.D., Daniel Talmor, M.D., M.P.H., Alain Mercat, M.D., Jean-Christophe M. Richard, M.D., Carlos R.R. Carvalho, M.D., and Roy G. Brower, M.D. N Engl J Med 2015; 372:747-755 February 19, 2015 DOI: 10.1056/NEJMsa1410639 BACKGROUND Mechanical-ventilation strategies that use lower end-inspiratory (plateau) airway pressures, lower tidal volumes (V T ), and higher positive end-expiratory pressures (PEEPs) can improve survival in patients with the acute respiratory distress syndrome (ARDS), but the relative importance of each of these components is uncertain. Because respiratory-system compliance (C RS ) is strongly related to the volume of aerated remaining functional lung during disease (termed functional lung size)...
