I just had this surgery in September with the fibular free flap, and agree with Christine that the OR and Rooms are kept cool here, and I usually need two or three blankets to keep warm. What I had was a smal humidifier over the trache for a few days, nasal tube. compressions stockings, various drains, foley and boot on the flap donor leg. They did check the jaw flap with a portable Doppler for blood flow hourly.
Good luck
