  We study triatomic systems in the regime of large negative scattering lengths
which may be more favorable for the formation of condensed trimers in trapped
ultracold monoatomic gases as the competition with the weakly bound dimers is
absent. The manipulation of the scattering length can turn an excited weakly
bound Efimov trimer into a continuum resonance. Its energy and width are
described by universal scaling functions written in terms of the scattering
length and the binding energy, $B_3$, of the shallowest triatomic molecule. For
$a^{-1}<-0.0297 \sqrt{m B_3/\hbar^2}$ the excited Efimov state turns into a
continuum resonance.
