Dear vasopressin, where is your place in septic shock?

Cardiovascular failure is one of the central therapeutic problems in patients with severe infection. Although norepinephrine is a potent and, in most cases, highly effective vasopressor agent, very high dosages leading to significant side effects can be necessary to stabilize advanced shock. As a supplementary vasopressor, arginine vasopressin can reverse hemodynamic failure and significantly decrease norepinephrine dosages. Whether the promising possibility of 'bridging' advanced septic shock when the benefit/risk ratio of catecholamine therapy leaves a clinically tolerable range may improve quantitative and qualitative patient outcome can only be determined by a large, prospective, randomized study.
