  We present some wormhole configurations using analytic and numerical
solutions of the Euclidean field equations considering Einstein Gauss Bonnet
dilaton coupled interaction in the Robertson Walker metric. Analytic solutions
invoking slow-roll type approximation for some potentials yield identical
wormholes in the early era. Eventually, in a later era, the universe enters to
an expanding era much faster than usual inflation accompanied by oscillations
with analytic continuation \tau=it. The numerical solutions of wormholes in
terms of the scale factor a(\tau) are almost identical for some standard
potentials of the dilaton field, except for the evolution of potentials. The
Hubble parameter and deceleration parameter obtained by curve fit of a(\tau) of
the numerical solution of wormhole yield an inflationary era away from the
throat of the wormhole using \tau=it. A sharp decay of the potential is also
observed.
