I'm just a newbie (only 5 weeks post op) but I always bring 2 bottles of water, a flushing syringe, and a small k basin (any tray will do) plus all necessary supplies. I always flush the tube once while intubating, and then once more after I remove it from the stoma. If possible I also flush the catheter with hot water in the sink. I carry a small can of air freshener, dry off the catherter with TP, give it a quick spray of Fabreeze, and presto, no odor! I promise, it will work like a charm!
