1In certain instances when the sump did not reach or did not remain in the cul-de-sac, we were not successful in avoiding stagnation. Such a stagnant pool can be the source of unintended overhydration if it remains after ionic equilibrium is reached. The time required for this depends on the fluid volume, but it is surprisingly short. Therefore, it is essential to remove a stagnant pool of fluid before it loses hypertonicity.
