“…AVP and copeptin levels proved to be clearly correlated in trauma patients, confirming once more the role of copeptin as a surrogate marker for AVP [15]. Moreover, in a cohort of patients with severe trauma, AVP levels were significantly higher in patients with ISS > 15 compared to those with ISS < 15 [23]. Interestingly AVP did not show any correlation with SBP in patients with trauma, suggesting that, in trauma patients, a drop in SBP may not be the only trigger to AVP release, and/or that AVP secretion may be highly effective in sustaining hemodynamic stability, at least in a first compensated phase [16].…”

“…Its use in hemorrhagic shock was associated with increased survival in animal studies and in several case reports on humans [35,36]. Although the studies on the relationships between AVP, hypoxia and hypoperfusion are at their early stages, it is intriguing to consider that an early responsiveness of AVP to hypoperfusion (in addition to the other wellknown AVP-triggering stimuli) would explain both the stronger correlation of copeptin with the need for transfusion than with hemodynamic parameters reported in previous studies, and its high reliability, even higher than that of lactate, in predicting the clinical course of patient lacking overt initial physiologic derangement that we observed [23]. It is fascinating to speculate that in the challenging situation of early management of trauma patients copeptin may support the clinician in identifying occult hemorrhage before a drop in SBP or in hemoglobin level.…”
