I have been fortunate, or I guess unfortunate enough to have 2 surgical airways under my belt. One medical scenario and one trauma, performed with a different technique each time with the second one being dictated by my medical director's (at the time) preferred method. Honestly, there is some blood, but it's not a blood bath as some make it out to be. As long as you stay midline and away from the vascular structures that run parallel to midline you're all good. An open surgical airway is a procedure that is done all by feel, or at least should be, so blood obscuring your visualization shouldn't be a worrying factor. As stated here the biggest difficulty is just mentally committing to the procedure itself. Once executed it's an easy day, you have likely just saved a life, and the minor bleeding is easily controlled with 4x4's cut into trach sponges with scissors. Hold them in place as you hold the tube for the duration of the transport.
Given a known airway obstruction in the unconscious patient, that I can't visualize using DL and remove with Magill forceps or dislodge with CPR, I'm absolutely resorting to a surgical airway as a last ditch otherwise the patient is priority 4.
