  QCD sum rules for positive and negative parity heavy baryons in the heavy
quark limit are formulated. We apply the method to $\Lambda$ and $\Sigma$
channels. We include the next-to-leading order corrections in
$\alpha_s$-expansion to dimension 0 and 3 terms in the operator product
expansion. The corrections lead to the considerable reduction of the predicted
masses and significantly improves the stability with respect to the Borel
parameter, especially for negative parity states. It is also found that in the
heavy quark limit chiral odd condensates do not contribute to the negative
parity states.
