Postconditioning of stellate ganglion block improves intestinal barrier function by inhibiting autophagy in conscious rats following hemorrhagic shock and resuscitation

To the Editor:Hemorrhagic shock is a critical pathological process characterized by microcirculation dysfunction and hypoperfusion,with severe consequences of cell damage and organ dysfunction.Intestinal barrier dysfunction is a critical link of distant organ injury caused by hemorrhagic shock.Prophylactic treatment with stellate ganglion block(SGB)significantly reduces hemorrhagic shock-induced intestinal barrier damage.
