We present a study of the inelastic decay rate of quasiparticles in a two-dimensional (2D) electron gas with spin-orbit interaction. The study is done within the ${G}^{0}{W}^{0}$ approximation. The spin-orbit interaction is taken in the most general form that includes both Rashba and Dresselhaus contributions linear in magnitude of the electron 2D momentum. Spin-orbit interaction effect on the inelastic decay rate is examined at different parameters characterizing the electron gas and the spin-orbit interaction strength in it.
