A variety of therapeutic agents has been recommended to increase blood flow in shock, including vasodilators,⁷ ganglionic block agents,⁸ adrenergic blocking agents,⁹ isoproterenol¹⁰ and corticosteroids.¹¹

Dextran has been widely used in the emergency treatment of shock associated with blood loss,¹² but it has not been routinely employed in hypotensive patients without a history or signs of blood volume depletion. The ten patients studied in the present report became acutely hypotensive without obvious blood loss. Right atrial pressures were not significantly elevated, indicating the absence of overt right . . . [Full Text PDF of this Article]
