Hyperbaric oxygen: a useful adjunct for purpura fulminans: case report and review of the literature.

Introduction: We report a case of a previously healthy adult with flulike symptoms who precipitously declined due to pneumococcal sepsis complicated by disseminated intravascular coagulation (DIC) and purpura fulminans (PF). After one week of care, including ventilation support and hemodialysis, the patient was stable enough for hyperbaric oxygen (HBO2) in an attempt to salvage his threatened extremities. HBO2 resulted in reduction of ischemic tissue and demarcation of blackened tissue to the distal digits.
