Overview

1. Preparation2. Triage3. Primary Survey4. Resuscitation5. Secondary Survey6. Continued postresuscitation monitoring and re-evaluation

7. Definitive care

PreparationPrehospital

Notify receiving hospital Closest appropriate facility Report pertinent information

Inhospital Warmed IV solutions Ancillary departments notified Equipment made readily available Hospital personnel protection

Endotracheal Surgical

Breathing Supply O2 Ventilate alveoli

Resuscitation

Secondary Survey (PE)Maxillofacial

Midline facial fracturesBite occlusionBleedingFracture repair can wait

Midface FracturesLaFortI: Maxilla only transversely above the alveolar ridge

Most common isolatedII (pyramidal): Through nasal bone or nasal bone disarticulation with frontal bone

Most common when associated with other fractures

III (dislocated face): Through nasal bone, across floor of orbit, through lateral wall of orbit, zygomatic arch Rare
