The absolute safe limit of tourniquet duration has not been established and may depend on location and vary from animal to animal. The usual clinical recommendation is to limit the time of tourniquet to 2 hours, although in the author’s clinical experience this time has sometimes been exceeded with no negative consequences. In experimental rhesus monkeys, the systemic changes produced as a result of the application of a tourniquet for periods of up to 3 hours were not marked and readily reversible, and the local acid–base changes in the ischemic limb recovered in less than 40 min post‐release [111]. However, it should be noted that these were healthy animals, and shorter tourniquet times are recommended in debilitated animals.

It is recommended to use a staggered tourniquet release, which will both avoid a sudden release of local anesthetic into the systemic circulation and will reduce the cardiovascular consequences of limb reperfusion.
