We propose to model the dissipative hydrodynamics used in description of the multiparticle production processes (d-hydrodynamics) by a special kind of the perfect nonextensive fluid (q-fluid) where q denotes the nonextensivity parameter appearing in the nonextensive Tsallis statistics. The advantage of q-hydrodynamics lies in its formal simplicity in comparison to the d-hydrodynamics. We argue that parameter q describes summarily (at least to some extent) all dynamical effects behind the viscous behavior of the hadronic fluid.
