Hemorrhagic shock: a review

I read with interest the review by Prof. Gutierrez and colleagues on hemorrhagic shock [1]. The treatment of hemorrhagic shock is addressed in the review, and mention is made of the main goals: to stop the source of hemorrhage and to restore the circulating volume. Conserving blood products, on the grounds of cost, restricted availability and their pathophysiological effects, is becoming a necessary shift in the approach to these difficult patients and was not touched upon in the review. There have been clear advances in recent years in developing other strategies to aggressively stem the flow.
