OBJECTIVE: Selective vasopressin V(1A) receptor agonists may have advantages over
arginine vasopressin in the treatment of septic shock. We compared the effects of
selepressin, a selective V(1A) receptor agonist, arginine vasopressin, and
norepinephrine on hemodynamics, organ function, and survival in an ovine septic
shock model. DESIGN: Randomized animal study. SETTING: University hospital animal
research laboratory. SUBJECTS: Forty-six adult female sheep. INTERVENTIONS: Fecal
peritonitis was induced in the anesthetized, mechanically ventilated,
fluid-resuscitated sheep, and they were randomized in two successive phases.
Three late-intervention groups (each n = 6) received IV selepressin (1
pmol/kg/min), arginine vasopressin (0.25 pmol [0.1 mU]/kg/min), or norepinephrine
(3 nmol [0.5 ?g]/kg/min) when mean arterial pressure remained less than 70?mm Hg
despite fluid challenge; study drugs were thereafter titrated to keep mean
arterial pressure at 70-80?mm Hg. Three early-intervention groups (each n = 7)
received selepressin, arginine vasopressin, or norepinephrine at the same initial
infusion rates as for the late intervention, but already when mean arterial
pressure had decreased by 10% from baseline; doses were then titrated as for the
late intervention. A control group (n = 7) received saline. All animals were
observed until death or for a maximum of 30 hours. MEASUREMENTS AND MAIN RESULTS:
In addition to hemodynamic and organ function assessment, plasma interleukin-6
and nitrite/nitrate levels were measured. In the late-intervention groups,
selepressin delayed the decrease in mean arterial pressure and was associated
with lower lung wet/dry weight ratios than in the other two groups. In the
early-intervention groups, selepressin maintained mean arterial pressure and
cardiac index better than arginine vasopressin or norepinephrine, slowed the
increase in blood lactate levels, and was associated with less lung edema, lower
cumulative fluid balance, and lower interleukin-6 and nitrite/nitrate levels.
Selepressin-treated animals survived longer than the other animals. CONCLUSIONS:
In this clinically relevant model, selepressin, a selective V(1A) receptor
agonist, was superior to arginine vasopressin and to norepinephrine in the
treatment of septic shock, especially when administered early.
