Stephanie; I am not entirely clear about your question. Are you saying that the literature shows that elevated lactate (>3.9) in the face of severe sepsis does NOT indicate shock? The definition of shock is impaired perfusion to tissues - this causes anaerobic metabolism and the production of lactic acid. One could argue about the arbitrary choice of 4 or greater - but how can you argue that tissue hypoperfusion (or the use of lactate as a surrogate of deranged perfusion) is not a valid physiological marker? Blood pressure is only ONE component of adequate perfusion and everyone is willing to hang their hats on this. Combined with cardiac dysfunction, intravascular volume depletion and micro-vascular clotting, a low BP is concerning - but if the other 3 are present, even in the absence of low BP (often in younger folks or hypertensives) a high lactate is a very important indicator of hypoperfusion = shock

We have had conversation with the physicians at our facility about the value and appropriate use of Lactate levels. However, it is still part of the Surviving Sepsis Campaign and we're stuck with Lactate levels being part of the criteria for determining Septic Shock in the Core Measures world, at least for the time being. How are others dealing with a perceived discrepancy between current literature and the Sepsis Core Measure guidelines? Not everything that counts can be counted, and not everything that can be counted counts.

"Septic shock: sepsis with persisting arterial hypotension or hypoperfusion despite adequate fluid resuscitation." Lactic acid is a measure of tissue hypoxia indicating severe sepsis defined as sepsis with organ dysfunction, hypotension or hypoperfusion. This is a good reference showing all of the lab indicators and their meaning. http://www.clevelandclinicmeded.com/medicalpubs/diseasemanagement/infectious-disease/sepsis/ Lewis Holmes, MD, MPH Porter Medical Center On Nov 13, 2015, at 1:03 PM, Harkey,Jessica <[email protected]<mailto:[email protected]>> wrote: This patient has already coded out with a sepsis diagnosis, therefore the elevated lactate would be the criteria for septic shock. The way I understand the intent of the treatment, the measure and criteria, is that even if there were other types of lactic acidosis, the sepsis will more than likely be higher risk of mortality therefore treat the septic shock without delaying while other sources of lactic acidosis are considered. So infection + SIRS+ shock (lactate >4)= implement the bundle timely and treat sepsis first regardless of other potential sources of lactate. Then evaluate after the bundle has been completed.
