Although the review quotes many references, much of the basis for the conclusions are from 2 experiments, both originating from the authors' own laboratory. As a result, the authors tend to look at the field as a whole in the perspective of these 2 reports, which have major flaws.First, the dose of endotoxin used to induce lethality is 400 times greater than the dose that causes moderate to severe hypotension in dogs. Indeed, the same group worked diligently for years to develop a sepsis model using an intraperitoneal septic clot that more closely simulates the human cardiovascular response than the endotoxin bolus model. Interestingly, when they finally used the clot model to study
