GOALS FOR THE RESUSCITATION OF SHOCK

Objective: To remind practitioners of the conventional goals of resuscitation of overt hypotensive or uncompensated shock (''ABC,'' for airway, breathing, and circulation) and to introduce additional goals, represented by successive letters of the alphabet, to aid clinicians in recognizing the persistence of compensated shock in the splanchnic organs and in achieving more complete resuscitation by eliminating inadequate tissue perfusion in these organs. Data Sources: Review and analysis of current medical literature on shock and organ failure, combined with the author's prior research and expertise in the areas of tissue oxygenation and tonometric monitoring in the critically ill. Conclusions: In traumatic and septic shock, multiple system organ failure is associated with a persistent state of compensated shock in which hypotension and oliguria are corrected, but in which inadequate perfusion persists in the splanchnic organs and especially in the mucosal lining of the gut. The additional goals recommended include ''D'' for increasing the delivery of oxygen to levels that meet the metabolic demand by all tissues in the body, especially those tissues within the splanchnic circulation, and ''E'' for ensuring extraction and utilization of oxygen by the tissues. Future needs for goals that address reperfusion injury, translocation of bacterial toxins, and the release of toxic mediators are also considered.
