Lethal injection is the standard way. However, an inmate can request other methods. Electrocution, gas, hanging, and firing squads are still allowed in some states, if the inmate wants it or if lethal injection isn't available.
As for track record, one just happened last month.
If it really is that rough and states are still doing it then that is just fucked up. Whether it's using dated drugs or cheaping out or whatever. None of that should happen (coughing/struggling/not dying in a reasonable timeframe).
