We stopped using Mastisol a few years ago and we have never used the NeoBars, which I have used at other facilities.
We use a bone (Which is actually an umbi clamp that has a hole drilled through the middle. The holes are individually drilled to match ETT size). This is clamped onto the ETT. We use Cavilon (which we love) on the cheeks, followed by a layer of Replicare, then a piece of cloth tape on each side. The cloth is cut like a "Y" and the top end wraps around the tube while the bottom end wraps around the bone, and we aim for a "fish lip", or for the lips to be puckered. It works fantastically and our accidental extubation rate is low.
