 Although technically possible to maintain an airway with the supralaryngeal ETCKing LT-D, endotracheal intubation has been the gold standard. In the trauma setting, if a patient has arrived in the trauma bay with a supralaryngeal airway in place, it has traditionally been exchanged out for an ETT during the primary survey initial assessment. This exchange is possible using a number of techniques widely described in the literature. Although the skilled anesthesiologists reportedly can do this exchange safely and rapidly according to a limited number of clinical trials, the safety of the exchange during the primary survey and initial resuscitation of the trauma patient has not been well documented.
