Typical protocols for postconditioning. (1) Control ischemia. (2) Postconditioning with a series of interruption of reperfusion (stuttering reperfusion), which consists of 3 or more cycles of brief reperfusion and occlusion. (3) Postconditioning with a single period of ischemia, hypoxia or anesthesia. (4) Postconditioning was induced by injection of neurotoxic agents. Solid bar, ischemia; open bar, reperfusion. The therapeutic time windows for postconditioning vary from a few seconds to 2 days after reperfusion.
