Synopsis

Coma bullae : Coma, Flaccid bullae, Pressure exposure, Tense bullae, Immobilized patient
Coma bullae are typically large bullae that are caused by physical forces.

They occur in comatose or immobile patients at points of maximum pressure and in patients with neurologic disorders. They form within 48-72 hours after the immobility. They can be skin colored or red / purple from hemorrhage. Coma bullae have been associated with barbiturate overdose.
