Hey Akhila !

As per the details of the Round 3 of AIIMS UG Counselling for the course of MBBS. The cutoff rank for AIIMS Bhubaneswar was :

General Rank : 9038

SC category Rank : 171

Your SC rank of 145 seems to be quite well ahead of the stats mentioned regarding that of above, hence there's a good chance that by the end of the Counselling rounds, you might end up in AIIMS-BBSR.

Good Luck !
