01Approach to the Critical Patient/attcp49

Immediate priorities

›Airway management (highest priority)

›Le Fort III carries the highest tracheostomy rate among Le Fort patterns (43.5%)

›Posterior midface displacement causes oropharyngeal obstruction

›26.5% of Le Fort patients present with airway obstruction

›Orotracheal intubation is the preferred emergent approach

›RSI if no suspected cervical spine injury precludes in-line stabilization

›Surgical airway (cricothyrotomy or tracheostomy) if oral intubation fails

›Avoid nasotracheal intubation if skull base fracture suspected

›Theoretical risk of intracranial passage

›Recent evidence suggests equivalent complication rates to tracheostomy

›If severe midface displacement obstructs pharynx, manual anterior traction on maxilla

›Rowe disimpaction forceps technique

›Temporizing measure only

Hemorrhage control

›Hemorrhage threats

›Anterior nasal packing as first-line epistaxis control

›Bilateral nasal packing for posterior source

›Foley catheter balloon tamponade as alternative

›If refractory epistaxis, interventional radiology embolization

›Internal maxillary artery and branches
