Volume kinetics in a translational porcine model of stabilized sepsis with fluid accumulation.

Background: Fluid dynamics during and after a septic event is complex, but better knowledge could guide both fluid resuscitation and fluid removal. We aimed to compare fluid dynamics before and after sepsis in a clinically relevant mono-bacterial porcine model.

Methods: Twelve sows with a mean body weight of 56 kg were anesthetized, mechanically ventilated, and invasively monitored.

Temporary bilateral clamping of renal arteries induces ischemia-reperfusion: A new pig model of acute kidney injury using total intravenous anesthesia.

Ischemia-reperfusion (IR) is a leading cause of acute kidney injury (AKI), and pigs are commonly used in preclinical AKI models. However, existing models often vary in the methods used to induce ischemia, and the resulting AKI tends to be mild-to-moderate. Moreover, follow-up is often performed under volatile anesthesia, which, in contrast to total intravenous anesthesia (TIVA), can induce malignant hyperthermia and cause hemodynamic instability.
