I think if you can release your zanpakuto by only saying its name but without the release command, it is still a sign of having bankai. Kyoraku did that, and Tousen, and Renji... I can't remember anyone who does NOT have bankai being able to do that.

Also, I'm positive Isane did use healing Kido during the HM arc, when Ichigo and Unohana went through the Garganta and left her to heal the wounded.
