Because of the increasing popularity of arginine vasopressin it is important to evaluate its effects on microcirculatory blood flow. Such studies are crucial if we are to appreciate the microcirculatory consequences of our various resuscitation strategies. However methodological issues must always be considered because they can significantly influence interpretation of the results. Some aspects of use of laser Doppler to evaluate the microcirculation are reviewed within the context of recent findings presented by Luckner and coworkers in this issue of Critical Care. Introduction Arginine vasopressin AVP is increasingly used in the management of refractory vasodilatory shock. Indeed it was recently incorporated into the recommendations grade IIB proposed by the American Heart Association for treatment of refractory septic shock 1 and the guidelines of the Surviving Sepsis Campaign grade E 2 . However although the global haemodynamic effects of AVP are relatively well described its effects on the microcirculation are still largely unknown. In this issue of
