The head-tilt/chin-lift is the primary maneuver used in any patient in whom cervical spine injury is not a concern. The simplest way of ensuring an open airway in an unconscious patient is to use a head-tilt/chin-lift technique, thereby lifting the tongue from the back of the throat.
CONCLUSIONS: The safe placement of airway tubes for multiple of types of surgeries, in patients varying from newborns to 100-year-olds, is one of the reasons physician anesthesiologists train for many years. Prior to surgery, some patients are alarmed at the notion of such a breathing tube invading their body. They fear theyâll be awake during the placement of the breathing tube, or that theyâll choke on the breathing tube. Be reassured that almost every breathing tube is placed after your unconsciousness is assured, and breathing tubes are removed prior to your return to consciousness. A sore throat afterward is common, but be reassured this is a minor complaint that will clear in a few days.
