The {ital ab}-plane thermal conductivity {kappa} of single-crystal Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8{minus}{ital x}} has been measured from 25 to 300 K, for samples of varying oxygen configuration. Complementary electrical-conductivity measurements on the same crystals allow {kappa} to be accurately decomposed into electronic and phonon contributions. For metallic samples the electronic contribution to {kappa} is substantial. Analysis of {kappa} in the normal and superconducting states allows the defect-scattering and electron-scattering contributions to {kappa}{sub phonon} to be evaluated near {ital T}{sub {ital c}}. {kappa} in the superconducting state is consistent with a BCS description.
