Matilda's UTH has been disconnected and I am now using a red bulb heat lamp on a REAL thermostat, which I raised slowly to 89. I didn't want to flood her tank with heat after it had been in the upper 70's alone while I waited for the vet visit and purchasing of the bulb/fixture. She seems to enjoy it as she's stayed in her warm hide since I turned it on (I think she's still recuperating from being manhandled at the vet yesterday). I've been instructed to give her a betadine bath every day, plus a light smear of silver sulfadiazine, and she's receiving injections of Fortaz every 72 hours. Now...I absolutely promise to follow all advice to the letter, as I have a few questions about some of the aspects of the burn healing process:

1)I've read conflicting articles on whether to rinse the snake after the betadine bath, but to me, rinsing her seems like it would defeat the purpose of the betadine in the first place...What are your thoughts?
2) How can I keep her tank humidity up to 50% without misting or getting her paper towel substrate wet/damp?
3) Any other advice is not only welcome but encouraged. I really want to do right by my snake and correct the mistake I made. I really do have her best interest at heart and I really reeeeally want to see her make a full and quick recovery. (Well, as quickly and *safely* as possible). I've learned my lesson about not following advice on here and I really am seeking to kind of 'mend-fences' by showing I really can listen and observe advice. I'm asking humbly for your guidance to help me on this path to getting my gorgeous snake back to good health. Please and thank you!
